3/23/2015 — Japan moves forward on WIRELESS POWER using Microwaves — SPS coming soon

March 23, 2015 Michael Janitch

Japanese move forward on wireless power using microwaves!

New experiments done in Japan by the Japanese Space Agency, confirm older findings from NASA – that wireless power is VERY efficient in the microwave band of 2-3GHz (S- band RADAR classification).
Much more efficient than using wires!
The Japanese are now developing a space based satellite to collect huge amounts of solar power, which is then converted into microwaves , transmitted to a Receiving antenna on the ground, and converted into DC energy for electrical use.

Microwaves sent from a transmitter to a receiving antenna. The receiving antenna hooked up to a circuit made of rectifying diodes which convert the microwaves into DC power.

The receiving antenna (rectenna) converts the microwaves into DC power by taking the microwave in through the regular receiving antenna, then passing the signal through a Rectifying Diode, which then usually passes through a Low Pass Filter, which then ultimately passes into a DC to DC step up / step down “buck converter” — to scale up the power or scale down the power for using regular household electric powered items.

Whatever signal the antenna picks up  is originally in “AC” inside the antenna, thus a “rectifying diode” is needed to obtain useable steady voltage… rectifying the radio wave into DC voltage.
I suppose the amperage would ultimately depend on the number (or size) of the input antennas , and the rating of the diode being used to rectify the microwave signal into useable power.
All done at 2.4GHz to 5GHz.
2.45GHz – 5 GHz also just so happens to be a common wi-fi frequency used by most 802.11 systems on our computers, mobile phones, and tablets.  Bluetooth also operates (usually) in the 2.4GHz microwave range.
2.45GHz also cooks your food in your kitchen microwave (at 1000Watts)

“Japan Space Agency Advances in Space-Based Solar Power
It’s one small 55-meter step for Japan’s aerospace industry, but perhaps a giant leap into developing a new energy source for mankind.
The Japan Aerospace Exploration Agency, or Jaxa, said it succeeded in transmitting electric power wirelessly to a pinpoint target using microwaves, which is an essential technology needed for the realization of space-based solar power.
According to a spokesman at the agency, the researchers were able to transform 1.8 kilowatts of electric power into microwaves and transmit it with accuracy into a receiver located 55 meters away. The microwave was successfully converted into direct electrical current at the receiving end. The experiment was conducted Sunday in Hyogo prefecture in western Japan.
In space-based solar power generation, sunlight is gathered in geostationary orbit and transmitted to a receiver on earth. The Jaxa spokesman told Japan Real Time that Sunday’s experiment was the first in the world to send out high-output microwaves wirelessly to a small target.
According to the U.S. Department of Energy, more solar energy reaches the earth every hour than humans use in a year. Unlike solar panels set on earth, satellite-based solar panels can capture the energy around the clock and are not affected by weather conditions.
If implemented, microwave-transmitting solar satellites would be set up approximately 35,000 kilometers from earth. Jaxa says that a receiver set up on earth with an approximately three-kilometer radius could create up to one gigawatt of electricity, which is about the same as one nuclear reactor.
It’ll be many years before that happens, if it ever does. Researchers “are aiming for practical use in the 2030s,” Yasuyuki Fukumuro, a reasearcher at Jaxa, said on its website.
While the energy is transmitted in same microwaves used in microwave ovens, it does not fry a bird or an airplane traveling on its path because of its low energy density, according to the Jaxa spokesman.”

Laser-Powered Devices: High-concentration PV cell enables high-wattage laser power transmission

A high-performance, high-voltage VMJ photovoltaic cell enables high-wattage transmission of power via laser light for applications including remote powering of small UAVs and remote sensing.

MICO PERALES
Laser power transmission involves the transmission of power from a laser source either through free space (power beaming or PB) or via a fiber-optic cable (power over fiber or PoF) to a photovoltaic (PV) receiver. The PV receiver includes a PV cell, or an array of PV cells, optimized to convert a specific laser wavelength to electricity at high efficiencies, typically in the range of 30% to near 50%. Some uses include remotely powering unmanned aerial vehicles (UAVs), robotic devices, and hazardous environment or remote sensor applications.
MH GoPower (MHGP) produces a high-performance silicon-based vertical multijunction (VMJ) PV cell that enables high-wattage laser power transmission. The 3D design of the VMJ PV cell manages heat during high-wattage laser power transmission through the use of the bulk property of silicon, which includes fins integrated into the device. Here, we explore the applications and value proposition of free-space PB and PoF, as well as review the technology behind the high-performance VMJ PV cell.

FRONTIS. MHGP VMJ cell design provides for versatility.

Why power beaming?

When compared to battery-derived power, the advantages of free-space PB include increased operating time, a reduction or elimination of recharging events, and a potential reduction in weight. We illustrate these advantages by examining the UAV application. The flight time of a UAV can be extended in theory to indefinite duration, so long as the power beamed to the PV receiver on the UAV and converted to electricity exceeds the power usage.
By extending flight time, the need for the operationally sensitive and technically risky maneuver of landing for recharging is reduced. Also, if extended flight duration is required, rather than attaching additional batteries and adding weight to the UAV, a lighter-weight PV receiver can be deployed to achieve the extended-duration requirements; this may also allow for additional payload capacity.

Why power over fiber?

There are several advantages of sending power over fiber rather than through copper. Power delivery through copper is susceptible to RF and magnetic field interference, which can result in power surges or other signal anomalies that can damage equipment, making systems unreliable. Furthermore, copper wiring serves as a ground path for lightning strikes and can induce sparks in high voltage or poorly insulated environments. Power by laser light suffers none of these problems.

Some examples of applications that benefit from these advantages include sensors and other devices operating in hazardous, explosive, or high-voltage environments (current sensors), devices exposed to harsh weather such as lightning (outdoor video surveillance cameras as an example), and devices requiring noise immunity (medical monitoring equipment and military applications).

Barriers to market acceptance

Laser power transmission applications have been primarily limited by system costs. The metric for these costs is cost per watt of delivered electrical power. Driven by shrinking device sizes and improved efficiencies, costs per watt for laser systems have been coming down dramatically and are expected to continue declining. However, lasers are only part of the cost of a laser power transmission solution. Other key components are the fiber (for PoF), the optics, and the PV receiver (cell array) subsystems.
The optics for PoF is a small part of the overall system cost. However, for free-space PB, the focusing optics cost increases as the application distance increases due to an increase in lens size. As a result, optics costs can quickly dominate the free-space PB system costs, and thus become the limiting factor on the practical range. Still, ranges of a few kilometers are economically and technically viable. Similarly, for PoF applications, the cost of the fiber begins to dominate costs over longer distances, generally limiting practical applications to a few kilometers.
Finally, PV receiver power density can play a significant factor in the viability of the laser power transmission solution. In order to ultimately reduce system costs, higher receiver power densities are required, and this can be achieved in two ways: 1) by increasing the power of the laser, thus increasing the intensity of light on the PV receiver; or 2) by increasing the efficiency of the PV receiver.
In the first scenario, the increased power of the laser results in a lower incremental cost per watt-up to a point. For example, in a free-space UAV application, the tracking hardware and software, laser mounting hardware, optics, UAV, and receiver size are all fixed, and thus an increase in the laser power does not increase the cost of these systems. In fact, it could mean that smaller batteries are needed, further reducing the incremental cost of adding this additional power. Consequently, as long as the PV receiver can perform well in the increased intensity laser light and can manage the heat, it is advantageous to increase the power of the laser source (the analysis similarly holds true for a PoF application).
In the second scenario, improving PV receiver efficiency results in more power output for a given PV receiver footprint and balance of system costs. Alternatively, it allows for the use of a lower-power and lower-cost laser system. A more-efficient PV receiver also means that there is less waste energy to dissipate, with the result that cells will operate cooler (a positive performance feedback loop) or that a lower-cost and often lower-weight heat sink can be used. Another advantage of more-efficient PV receivers is that the overall system efficiency will be enhanced, which is important for some applications in terms of both cost and system operation.

How the VMJ PV cell achieves high power density

The MHGP silicon-based VMJ PV cell (VMJ cell) is a cost-competitive concentrating PV cell, which works most effectively with laser systems with wavelengths in the 900 to 1000 nm range. The VMJ cell's material composition and device structure serve as the foundation of the cell's competitiveness for laser power transmission applications.
The VMJ cell is an integrally bonded series-connected array of miniature silicon vertical-junction unit cells. The VMJ cell is fabricated by bonding a stack of diffused and metalized silicon wafers together and then dicing the stack into thin slices, resulting in high-voltage, low-current cells that each contain approximately 50 unit cells (junctions) per centimeter of length, resulting in near 30 V/cm. Electrical leads are attached to the end contacts, so that current flows from the ends of the cells (see Fig. 1).

FIGURE 1. The MHGP VMJ cell has the potential to deliver higher power density than conventional cells through both application of greater light intensity and higher PV receiver efficiency.

Increasing intensity on conventional PV cells will increase output to a point. Gallium arsenide (GaAs) concentrating PV cells designed for laser light conversion require dense grid lines on the front and back surface of the cell to manage higher concentrations of light. This has the effect of reducing cell performance as intensities go up. The MHGP VMJ cell has been shown to maintain constant performance in efficiency (based on flash test results) up to intensities greater than 100 W/cm².
The major challenge for PV cells under highly concentrated light is managing the waste thermal energy. As intensities increase, cell temperatures rise, resulting in lower performance, which results in still proportionally greater waste energy. In other words, high intensities have a compound negative impact on cell performance.
The barrier to efficiently removing heat from PV arrays is the thermal interface layer (TIM), which bonds the PV cells onto the thermally conductive heat sink. Typically, this TIM must utilize a thermally conductive, yet electrically insulating material to prevent the current-carrying, electrically active cell surfaces or leads from shorting. As such, these TIM materials are typically not ideal thermal conductors. The result is that a barrier exists to heat transfer, resulting in a limit to the rate of heat transfer away from the PV cell.
To improve heat dissipation, we have incorporated a number of innovations into our VMJ cell and receiver designs, including: a) thick cell architectures (up to 1 cm thick); b) end-contact heat dissipation; and c) embedded heat-sinking structures in the PV device. In combination, these features enable some novel heat-dissipation solutions.

FIGURE 2. WiFins are integrated fins that dissipate heat from a PV cell via a heat path that does not need to pass through the receiver's thermal interface layer (TIM; the layer that bonds the PV cell onto its thermally conductive heat sink).

As an example, thick VMJ cells with integrated "fins" (called WiFins; see Fig. 2) improve heat-sinking by increasing the cell's surface area for radiant and/or convective cooling, allowing heat to be dissipated without having to pass through the TIM bottleneck. Thick VMJ cells with metalized end contacts use a metallic, bonding material with high thermal conductivity to attach the large-surface-area end contacts to an electrically conductive heat sink, which doubles as the device's anode and cathode. These innovations enable the VMJ cell to more effectively dissipate heat, leading to higher-intensity power operation.

PV receiver efficiency

Finally, the MGHP VMJ cell also improves PV receiver efficiency. This is accomplished through the VMJ cell's customizable size (up to 7 x 7 cm in width/length) and high voltage characteristics. The customizable size allows the cell to be matched in size to the expected spatial nonuniformity of the application. In other words, a highly spatially nonuniform beam pattern would require smaller cells, which would be paralleled together, avoiding series losses. A beam pattern that varies more slowly spatially would allow for larger cells, again paralleled together.
This completely parallel architecture is viable due to the high-voltage nature of the VMJ cell, which along with the customizable cell size, allows the PV array to easily approximate the voltage requirements of the end application, thus helping to reduce the costs, inefficiencies, and additional weight requirements of step-up converters.
The benefits of delivering power via fiber or through free-space are spurring the growth of new applications. To further accelerate the adoption of these applications, additional system cost reductions must be achieved. This will continue to occur due to the expected drop in laser prices, but can be further spurred by the incorporation of the MHGP VMJ cell into PV receiver designs, resulting in greater PV receiver power densities that will further lower laser power transmission system costs.

Programming: An Essential Skill For Network Engineers

As software takes over the networking discipline, engineers who don't learn to code a general-purpose programming language will be left behind.

I'm going to start off with a disclaimer: I teach Python courses to network engineers, so I have a vested interest in programming. Nonetheless, I regard the following as true.
In 2011, Marc Andreessen wrote an article called "Why Software is Eating the World" (subscription required). In it, he predicted:

Companies in every industry need to assume that a software revolution is coming. This includes even industries that are software-based today. Great incumbent software companies like Oracle and Microsoft are increasingly threatened with irrelevance by new software offerings...

In some industries, particularly those with a heavy real-world component such as oil and gas, the software revolution is primarily an opportunity for incumbents. But in many industries, new software ideas will result in the rise of new Silicon Valley-style start-ups that invade existing industries with impunity. Over the next 10 years, the battles between incumbents and software-powered insurgents will be epic.

During the last few years, we have seen the rise of software-defined networking. Cisco has launched both its onePK API and its Application Centric Infrastructure, and VMware has countered with its NSX overlay-underlay networking model. Network engineers are increasingly using DevOps tools like Ansible, Puppet, and Chef. Additionally, Amazon Web Services, OpenStack, and other software platforms are making the software-defined data center a reality. Finally, white-box switches have the potential to standardize and commoditize networking hardware.
Networking has joined the software-eating-the-world buffet
But what do all these changes imply for network engineers? Is it all business as usual, and do we just need to continue pounding on our CLI? Or is this a fundamental change in the networking industry?
I think that it is a fundamental shift, and that programming skills will be increasingly important for network engineers.

Many of us have seen the great advances that server engineers have made in automating their environments; network engineers need to keep pace. But in order to keep pace, we need better methods of programmatically controlling equipment, better tools, and an increased use of network virtualization. Network engineers also need programming skills to use the new tools and the new programmatic access.
Now, I am not saying that you need to be Linus Torvalds or Guido van Rossum, but you must be fairly proficient in a general-purpose programming language. (Python and Ruby are good choices.) You need to add this important skill to your tool belt.
For many of you, this is not entirely new. Lots of network engineers have known how to program for years and years. Network engineers have been hacking together shell, Perl, and Python scripts for quite a while. But the requirements of network engineering and the job market are now requiring more -- more network engineers with programming skills and a broader and deeper understanding of programming.
Obviously, not all network engineers need to learn to program, but it is a valuable skill to have (and will be increasingly so). There are certain jobs, roles, and companies that will be immune to this, but for many of you, it's in your interest to acquire or improve programming skills.
But can't I just use the tools other people create for me?
Yes, but if these are DevOps tools like Ansible, Puppet, and Chef, then these tools themselves have numerous programming constructs built into them. For example, Ansible has lists, dictionaries, loops, and conditionals. It actually has multiple forms of these, if you consider both the main script (the playbook) and templates. Additionally, if you want to be proficient at automating tasks in your environment, you will need to write your own glue scripts and potentially add your own code to DevOps tools. These tasks require programming skills.
But can't I just buy a large network controller with a GUI that does all this for me?
I am sure vendors will be happy to sell you a very large, very expensive network management package. However, this hasn't worked very well in the past. If a vendor could accomplish this on a broad scale, that would be great.
Additionally, many of the large management programs will result in increased network virtualization (VMware NSX, OpenStack), including virtual switches, virtual routers, virtual firewalls, and virtual load balancers. These virtual network devices can be created, configured, and destroyed programmatically.
Finally, a management program would still need to integrate into your environment and workflow. This integration would often involve programming.
But can't I just think like a programmer?
Learning and doing are closely related. I doubt that you will be able to reasonably understand programming practices without learning how to program (at least to a certain extent).
By all means, use tools. Find the best tools you can. But one of these tools should be a general-purpose programming language.
Time will tell if I am right or not -- making predictions about the future is a dangerous game. If programming skills are important for network engineers, then they will allow you do your job significantly better, and your market value will increase. The evidence I see so far indicates that these skills are important, and that they will be even more important in the future.

Re: Languages Of Choice?

hello Calbert234,
In my job, we often work with  transmission team, and i've remarked how SDN will impact  this part of telecom network, more and more telecom vendors propose SDN solutions.

When we see how the number of BTS, NodeB, eNodeB... increase quickly, how the traffic flow coming from many technologies (xdsl,fr,atm,mpls,vpls,wimax,2G,3G,4G...) increase, backhaul all that with some constraints or propose a transmission path  become more and more complex.

Re: Languages Of Choice?

So, what i can suggest you, is to  increase upon your skills in java, learn and pratice C/C++, python, ruby, perl -- if i must propose high level languages; but notice that it also depends  of the vendor, so try to get more information about their SDN solution. (what are the suitable programming languages  to program their equipments)
And, work generally to increase upon your algorithms skill.
Please, try also this link : http://yuba.stanford.edu/~casado/of-sw.html

Re: Languages Of Choice?

For Network Engineers, I recommend that you become somewhat proficient in one language (as opposed to trying to learn several).  For that language, I would choose something that is high-level and that has a large active community (and consequently has a broad set of libraries available).  I would also probably pick a language where you can start being productive with it pretty quickly.  For these reasons, I think Ruby and Python are good choices.

Engineers Take Heed: Time to Program

An excellent and timely subject for sure.   And I could not agree more with the message.  Engineers need to be able to program or at least understand code when they come across it.   I have been an engineer for years and at no time do I take the idea of improving my programming skills more importantly than I do now.

I am working like crazy to make up for years of mis-guided effort.  I am learning C#, C and Python currently and my goal is to be proficient in all of the above by the end of the year.

Ultimately I may just program mainly, but first things first - I have to learn how.

Re: Engineers Take Heed: Time to Program

Hi Susan,    Sure, it comes from years of working as an engineer and really having nothing to show for it. I am approaching mid-career and I have to ask myself, do I want to do this in my golden years ? The answer is No.   Do I have more to offer the World ?   The answer is Yes.
I should have done this years ago, but engineering became a comfort zone coupled with bosses who for the most part worked against my aims.
Now, I am ready to take my fate into my own hands, if I have to work ( which I will) I will write code.   And I can't learn it fast enough.

My particuliar industry uses all three to some extent so I need to come up to speed on all of them.   Might be a tall task for some, but a necessary evil for me.

Technocrati, thanks for your candid answer. I think a lot of us have run into similar situations, where our industries are changing dramatically and you come to a point where you really need to shift gears in order to keep growing. I think people like you, with an engineering and programming background, will be in high demand, so you are wise to educate yourself.

Re: Engineers Take Heed: Time to Program

First if a network engineer needs to use a General Purpose Programing language for configuration of a router/switch/loadbalancer/firewall etc or even create network based app.
THEY MUST BEGIN WITH C, to get a strong foundation. Without this, just forget it. You will not be a strong programmer.  Many advocate that C is not required including Brajne Stroustrope, dont listent to him and one can jump direct to OOP, many a times they are like CCIE certified with CCNA knowedge.
Please learn C and UNIX Internals. Thats the trick to mastering C. Do not skip pointers in C. Without mastering pointers, there is no use of learning C, just learn FOTRAN which can do all what C can do except Pointers/anon acccess
 Then they must progress to OOPS/OOAD concepts and master the concepts.. Once C is completed and OOPS concepts are understoond, you can progress to Core Java coding and/or Python C++ simultaneous.
Once C , C++ and Core+Adv Java is understood. Then any programming langauage is easy.
Think C as the N+ and CCNA which are the fundamentals.
DO NOT DIRECTLY JUMP TO JAVA or PYTHON, albeit you can and many do and are also encouraged. Do not listen to them.
Appears hard, but really not. I am Network Architect 2xCCIE. Trust me programming is much easier and systems programming is easier too.
Many ask which is the one best programming lang to learn. Should I do C or can I directly learn Java, python or C#. Sorry must build your foundataion from C, dont worry you dont need to learn any assembly languages. Just the C compilation knowledge will make you understand assembly code.
Maybe for IoT, for the embedded devices you need to understand the assembly code but there is  usually  a C or CPP complier designed for it. Some parts which C cannot program, just get the intermediate file which is complation process produces and add the small piece of code of the assembly and send it to LD/linking loading for the complete program.  Also many still use C for embeded devices since its super fast and compact.  C++ is also popular with lots of bound checks and intelligent compliers. However C is still used.
But for network enterprise app, you would typically use Java/Python since its easier for larger programs due to objet oriented approach. Only realtime sys app use C,C++ or assembly.
 Learn atleast 3 languages C/C++, Java, Python . Not to forget databases.

Re: Engineers Take Heed: Time to Program

Sam,

Interesting Post.---i'm pretty new to the field ( 3-1/2 yrs) with a CCNP ( route/switch)-...currently working on the CCNA-Voice because of my current job. I figured that Engineers would need to step-up and learn skills outside of their-"Box"...so I've been looking everywhere for advise on how to start programming ( what to learn ,first); and so many people stated to start with Java and or Python ...and to pretty much forget about C, but not really saying why???? I actually remember reading a comment someone made stating that C is "Pretty Much obsolete"
--Pardon my ignorance, i know nothing about programming... but is that true??.----Anyway... you were the FIRST person that stated to Start with C in order build a foundation...completely against what the masses say ; and provided to what seemed like a valid  explanation. I dunno about anyone else but to me, that says-something.
---Since i'm new to programming and pretty much all languages look the same to me..( DIFFICULT)..i'm also very thankful that you compared the C-language with N+ / CCNA.---I didn't want to start at a level that i wasn't' ready for; I've seen so many ppl skip the "101-courses" for a given-topic and struggle because the foundation is no where to be found.--thanks again.

You're brave! Seems like you could get the same effect by just sticking forks in your head for a few hours... ;-) My vote would be to try and pick one language and get good at it, rather than spreading your effort (and focus) across multiples. But perhaps that's just me!

Re: Engineers Take Heed: Time to Program

Hello,
@ jgherbert, good, i think it's clear now that  network engineer need also to have skill in soft programming in order to survive! but now, don't you think that soft developper need also to renew their skills into networking?
Learn many programming languages is very good and could help because you can choose the appropriate for a specific task based on some criteria (number of code to write, power, platform supported, ...)
But i believe that fundemental in order to be confortable is to learn the differents concepts of programming, developp algorithms reflex , modeling methods ... Doing this will help when learning the language. For a task, have a program writen in Python and another into C, your understanding of programming concept will help you in the structure.
thanks

Programming: An Essential Skill For Network Engineers

Hello to all,
@ Kirk, great article.Thanks.
Programming skill was always good for a network engineer, I would say mandatory  for the success in his job. A network engineer in a task of defining a network design  for a company should consider the softs that will be used on the network and there have a good background in software development is a plus.
This is also true  in telecom domain, when we talking about design, optimization on the radio interface, some applications installed on smartphones make mostly what we call "push"   (queries update for example --) which consume  resources and has a significant impact on network performance. We consider this during development work on the radio interface; without knownledge in app soft dev, i think poor design or inadequate parameters settings can be found.

Also, in the case of software dev project that must run on a  network computing or Telecom net, a network engineer with a good skill in programming could  be suitable for  this job, for example when talking about IN -Intelligent Network, VAS - Value Added Services , ..

I have a friend (telecom & Network Engineer) who works for an IT solutions integrator, he told me that, the corporate give him most soft dev project which must operate on  network, because of his high skill in programming -- he is able to write the code according to the network caracteristics.  A Network engineer with strong  programming skill gets more opportunities!

Programming: An Essential Skill For Network Engineers

Personally, I've always practiced several software development languages  (web, scripting, programming, --  C,C++,C#,WPF,JSE,JEE,Android,JavaScript,HTML/CSS,PHP,TCL,VBA,VBS,Batch, Bash,PS,JavaFx,.....) and i see its importance when i configure network equipments via the CLI or when i manage systems or when i  make a network design -- and also gives me more assurance  with the advent of SDN.
Special emphasis should now be given to the "Software Development" module in the training program of network engineers (at school).

Software engineer & Cloud computing

I also believe that, it's now a need for a software developer,  to have a very strong skill into network computing  -- Having regard to the furture of cloud computing.

Re: Software engineer & Cloud computing

"I also believe that, it's now a need for a software developer,  to have a very strong skill into network computing  -- Having regard to the furture of cloud computing."

This has been the case for many years now; software developers have needed an understanding of the network on which their software will run - and that was before the cloud was even a thing. Many a good application has been ruined by testing it exclusively on a LAN. It is though even more critical now than it ever was...

Scripting versus Programming

One thing that I think is often confused - or at least glosed over - when this subject comes up is the difference between Scripting and Programming.
I am a scripter. I might use Python, Perl, bash, VB.Net or something else, but the fact remains that I do not consider myself to be a programmer. I don't want to have a career as a programmer; if I did, I'd have chosen that career earlier in life. What I do want though is the ability to automate tasks, or at least to understand the mechanisms and algorithms necessary to automate. The ability to write scripts to automate processing, analysis of data, querying of switches and so forth has been essential to my job as a network engineer for many years, and now that network devices are offering some more computer-friendly non-screen-scraping interfaces to us, my ability to script now includes the ability to more reliably and effectively manipulate those devices. Hoorah.
Does that make me NetOps? I dunno.

Re: Scripting versus Programming

Good point John. It seems like the term programming is used pretty generally. Looking ahead, do you see things changing in terms of networking pros needing to go beyond scripting?

Re: Scripting versus Programming

I suspect that as with most things, there will be opportunities to apply scripting/programming skills at a variety of levels. There's no question though that the more understanding you have of programming logic, the easier you're likely to find the next generation data centers. Of course, not everybody's going to adopt that new paradigm, and even for those that do, there's going to be a fairly long migration period until all our "old" (i.e. current) methods are pushed out the window.

Re: Scripting versus Programming I agree with John on the learning one language versus multiple languages issue (for network engineers)--I think you are better off learning one language.  There is only so much time in the day, and you are generally better off expanding your skills in a single language (as opposed to spreading yourself across multiple languages).
On scripting versus programming...some of this comes down to definition of terms.  I view scripting as being a subset of programming.  My definition of scripting would be a type of programming whereby you are writing small self-contained programs that accomplish specific needed tasks.
I agree, however, that writing scripts is not new for many good network engineers.  That many network engineers have been doing this for a long time.
I don't think it is all that worthwhile of talking about whether network engineers are programmers or not.  It is more important to ask what skills you need to do your job well and how much programming that entails (if any).
There also has been some recent discussions on whether "scripting" scales or not (Greg Ferro had a recent article on this).  Personally, I don't think this is a good way to frame the issue. We know programming scales...so a more useful question is what characteristics do you need to have to make your programming scale (or to make your programs maintainable).  This is more valuable than saying a certain type of programming doesn't scale.
I also agree with John that migration periods take a long time...i.e. the old methods are not going away anytime soon.  These kinds of transistions are going to play out over many many years.  I also don't necessarily see it as an either-or function (i.e. programming or CLI); I view of it more of an 'and' function (programming and CLI).  Just as the rise of automation in the server world has not eliminated the 'bash' shell.

Ketahanan pangan vs kapitalisme

(Bp.Mulyana Ahmad)

Kemajuan teknologi budidaya, pasca panen dan pengolahan pangan telah menyebabkan sumber pangan dikuasai dan terkonsentrasi pada kelompok usaha tertentu. Kapitalis pangan ini bertingkat mulai dari tingkat global, regional dan lokal.
Kapitalis yang mengontrol dan mengendalikan pangan dunia adalah: Pepsico, Nestle, Kellog, Danone, Coca cola, Kraft, Tyson, Mars dll. Tidak ada pengolahan pangan dengan omset kurang dari Rp 1 triliun luput dari kelompok ini. Kapitalis regional seperti kelompok Charoen Pokphand, Kerry, Tipco dll. Mereka masuk pada segmen pangan bernilai Rp 0,5 triliun ke atas. Kapitalis lokal seperti indofood, sinar mas, garuda food dll, tidak ada usaha makanan dgn nilai kapital 50 milyar yg luput dari kelompok ini.

Kapitalis makanan ini menguasai dari hulu sampai kehilir. Membuat persaingan tdk seimbang. Perkebunan buah dan sayur apapun yang anda tanam, tdk akan mampu bersaing dengan pulpy orange atau Tipco. Karena hanya buah segar terbaik yg mereka jual, sedangkan buah grade 2 dan 3 langsung mereka olah menjadi pulpy orange atau juice buah aneka rasa dan dalam aneka kemasan.

Anda ingin beternak ayam? Bila tdk masuk dlm mitra Charoen Pokphand, berarti anda akan menjadi pembeli DOC, pakan, obat, vitamin dari mereka. Ketergantungan yg sedemikian besar tentu pada akhirnya akan merugikan semua. Andai saja terjadi "katastrope" di Brazil, kita tdk akan makan tahu, tempe dan kopi kita kurang manis karena kuta import 2 juta ton kedelai dan 1,5 juta ton raw sugar dari Brazil. Andai hubungan politik kita terganggu dgn Australia, berarti kita tdk akan cukup makan daging sapi. Nasinya juga pasti kurang kalau hubungan kita dgn vietnam terganggu.

Artikel ini sy buat bukan untuk melawan kapitalisme tapi untuk menggugah kesadaran akan pentingnya kemandirian. Sangat penting bagi sebuah bangsa untuk mampu menyediakan sendiri kebutuhan pangan dasar meliputi sumber karbohidrat, protein, lemak dan vitamin. Ketahanan pangan adalah menjadi bagian terpenting dalam ketahanan nasional dan ketahanan semesta.

" Padahal dari sawit bisa bikin minyak goreng, mentega, sabun colek. Pelembut kue, busa shampo. Bahksn Bio diesel !!"

" Mau bikin pabrik CPO..Anda harus punya modal 30 milyar. Belum lagi lahan kebun ..Belum lagi pengolahan CPO menjadi olein minyak goreng. Tambah lagi 40 milyar"

"Mesin pengolah cpo bisa dikecilkan seukuran kulkas. Begitu juga dgn pengolah minyak gorengnya"

Mengecilkan proses pengolahan pangan menjadi kecil itulah kuncinya...Indonesia akan menjadi penghasil CPO terbesar di dunia..Tapi minyak goreng saja masih import dari singapore yg cuma punya 5 batang pohon sawit."

"Gula import 2,4 juta ton..Padahal kalo rakyat indonesia mau mengkonsumsi gula tebu cair yg pekat dan manis...Anda bisa produksi gula itu dgn alat sebesar kulkas..Rubah kebiasaan. Indonesia bisa mandiri..Tanam 100 batang tebu dipinggiran kali. Kebutuhan gula pasir perkapita tercukupi. Tapi gulanya cair"

" Satu kecamatan cukup 1 mesin,:
Pengolah minyak sabun biodiesel
Pengolah gula
Pengolah air minum dari air laut sekaligus pabrik garam
Pengolah sinkong jadi beras parboiled
Pengawet ikan. Ayam dan Daging
Pengolah susu
Pengolah juice buah
Pengolah tepung singkong modifikasi pengganti gandum
Pengawet cabe
Pengawet buah
Pengawet bumbu..

" Kalau terjadi katastropi bencana meletusnya beberspa gunung sekaligus. Negara sub tropik akan musim es panjang. Hanya negara tropis yg bisa bertani dan beternak karena masih hangat"

" Kita harus siap. Kalau alat yg sangat akurat bisa mendeteksi keberadaan bagian manapun dari hewan babi dgn kadar sekecil apapun atau bisa mendeteksi binatang ternak yg tdk disembelih secara syari. Industri pangan dunia akan hancur. Kita harus siap menggantikan peranannya"

"Kerang segar, tuna segar, kepiting segar, udang, yg diawetkan dgn teknologi berukuran mini. Akan tetap seperti baru dipanen ketika sampai di jepang. Mereka berani bayar mahal. Tiap desa di pinggir pantai kita kasih mesinnya. Mau export berapa banyak kita jabanin"

"Ingat ! Teknologi ini jangan menumbuhkan kapitalis baru. Gunakan untuk kesejahteraan bersama. Gunakan untuk kemandirian bersama."

" Tepung singkong, kentang, jagung bisa dimodifikasi dgn tekanan tinggi. Ini hal baru setelah modifikasi enzym. Mie instan akan sangat baik tanpa gandum. Roti, biskuit, kue dll akan memberikan hasil yg baik."

" Setiap gudang lelang ikan lengkapi dengan katalis palladium, carbon membrane dan pompa plunger untuk bisa memproduksi sendiri nitrogen cair. Setiap kapal 30 DWT membawa 1 tong nitrogen cair untuk digunakan nanoice generator kecil dgn diesel 9 Hp untuk penggeraknya. Produksi nanoice pengganti ice. Ikan beku yg dihasilkan bila dithawing atau dicairkan 40 hari kemudian, mutunya sama percis ketika baru ditangkap. Bila dicairkan setahun kemudian, ikan seperti menggunakan es biasa yg disimpan selama seminggu."

"Setiap gudang lelang ikan ditambahkan inkubator nanobubble ozone untuk mengoksidasi norovirus kerang-kerangan sekaligus membersihkan cangkang kerang"

"Bekukan dgn nanoice dan pencinta sea food mentah jepang berani membayarnya 4x lipat. Tdk akan allergi dan bersih. Bila ingin lebih mahal lagi berikan proses PIH. Kerang steril dalam kondisi mentah dan beku."

"Proses PIH ukuran mini cocok untuk mensteril lobster mentah atau sejenis lobster besar akan mudah dibuka kulitnya."

"Proses pih mini juga menetralisir toxin ikan balon dan mimi beracun yg mahal harganya."

"Kembangkanlah cara menangkap ikan tuna dgn pemingsan listrik kejut agar tetap hidup. Buat kolam raksasa dengan pendingin air lengkap dengan nanobubble oksigen. Lemak ikan tuna akan tumbuh maksimal dgn pakan yg diatur. Ikan tuna blue fin berlemak banyak sangat mahal harganya. Sempat dijual 1 milyar/ekor di jepang."

" Setiap perahu nelayan diberikan nanobubble generator ukuran kecil dan penampung air laut. Ikan berharga jutaan rupiah/kg (ikan napoleon, ikan sebelah, ikan kerapu dijual hidup"

" Mesin MDM mini bisa memisahkan daging ikan dari sisik dan durinya. Ikan rucah tdk berharga dinaikan nilai tambah menjadi itoyori dan surimi beku balokan"

" Itoyori dan surimi adalah bahan baku industri bakso ikan, otsk2, sosis ikan, kerupuk ikan, kemplang, mpek2 dll."

"Mesin pelumat daging ikan ball cutter sebesar gajah sdh tergantikan mesin turbo cutter dgn pisau tiga tingkat sebesar galon air. Dan sekarang tergantikan lagi dgn mesin multi stage cutter sebesar pergelangan tangan. UMKM bisa terlibat"

" Mesin pengisi sosis otomatis semakin mengecil dan yg terkecil adalah menggunakan aerogel dopping cnt sebesar selang air yg bisa berdenyut seperti perut cacing menekan adonan sosis dgn timbangan atau volume selalu sama. Mesin sebesar sapi skrg jadi sebesar selang air sepanjang 1 meter"

" Ikan asinmu putih bersih dan wangi dengan garam sisa proses pemurnian air laut menjadi air minum. Ikan asinmu akan steril bila penjemuran tertutup dgn hydroxyl radical generator sederhana menggunaksn plasma dan H2O2"

" Ice Cream dgn santan kelapa yg diolah secara dingin bisa lebih digemari ABG dan Ibu2 yg mau diet langsing. Asam lemak lauratnya tdk rusak sedikutpun dan efektif meluruhkan lemak dan cholesterol. Beda dgn ice cream kapitalis yg menambah gelambir perutmu"

"Minyak kelapa virgin oil dengan nano gold menyembuhkan jerawatmu dalam 30 menit. Kamu masih sabar pakai punya kapitalis yg penyembuhannya 30 hari?"

"Shampoo kapitalis bikin rambutmu terurai indah? Shampoo bulu ayam dinanoin bikin rambut keriting menjadi lurus dan indah"

"Roti gandum menyerap lemak yg ada dipencernaan. Roti katul beras yg baru digiling menyerap lemak yg ada di pembuluh darah termasuk pembuluh darah di otak"

" Perusahaan perancis memberimu mayonise berlemak, sementara mereka memakan mie dari tepung porang/suweg yg tumbuh di indonesia untuk mengurangi lemak tubuhnya"

" Semua mesin yg sy sebut Tdk lebih dari Rp 50 jt kalau diproduksi massal. Harga mesin asli sekitar Rp 1 milyar"

" 60% belanja rumah tangga indonesia untuk 4 komoditi:
1. Karbohidrat / beras/tepung
2. Kacang2an/biji2an (tempe tahu)
3. Protein (telur. Ikan &daging
4. Air

Ketahahanan pangan dgn diversikasi sumber karbohidrat. Kembalikan orang papua ke karbo dari aren. Kalau perlu tambahan dari tepung tapioka. Kembalikan jagung menjadi makanan pokok suku tertentu dan maksimalkan modifikasi tepung singkong"

" Hama busuk pangkal batang padi KO oleh semprotan nanosilver pada semaian padi"

" Kalau kadar silika sekam padi kering oven = 86%........??
Pernahkah ada upaya menambahkan silika sebagaimana memberikan pupuk N,P,K ke sawah??
Jika ya 10,3 ton padi/Ha didapat. Tanpa slica cuma dapat 6,4 ton/Ha. Penelitian harus diulang lagi berkali2
Dengan menambahkan nanosilica dari abu sekam padi, kita bisa menurunkan air untuk memberi kesempatan rumpun padi memperbanyak anakan vegetatif"

"Pupuk slow release yg dikonversi dari tinja manusia, kotoran ternak dan busukan daun, bentuknya sebesar kacang tanah. Luruh tiap detik memberi pupuk N P K Mg P2O5 tiap detik dan baru habis setelah 3 tahun. Petani bisa melakukannya sendiri secara berkelompok. Pupuk tdk akan hilang terbawa air atau hujan sebagaimana pupuk urea atau za. Pabriknya hanya pipa paralon 5 inchi setinggi 6 meter..
Pabrik nanosilica sekam padi hanya 2 buah ember dan tabung titrasi dan pengaduk Singkong"

" Di dalam singkong terdapat alfa bets dan gamma amilosa. Temperstur gel Masing2 adalah 50, 60 dan 86 ˚C. Tepung yg tergelatinasi pada suhu rendah digunakan untuk produksi pop mie. Harganya 3x lebih mahal. Semua tepung native tsb akan menggel pd suhu rendah bila dimidufikasi dgn tekanan tinggi 4.600 bar. Mie instan adalah aplikasi utama. Digunakan juga untuk membuat bakso dan sosis daging premium"

" Keajaiban akan terjadi bila dilakukan pada tepung jagung, beras, kentang dll. Ada yg meningkat kerenyahannya, tdk akan gosong meski suhu panas, ada yg selalu nampak basah dll"

" Teknologi nano berkembang pesat, tapi masih mencari bentuk idealnya. Semua akan mengalami percepatan bila hydrogen hasil splitting water bisa disimpan dengan density tinggi tapi bertekanan rendah"

"Pertanian modern kelak bisa menggunakan traktor bermesin listrik. Electromotor ukurannya kecil tapi torsinya besar. Mobil pengangkut batu bara dgn muatan 400 ton sekali angkut menggunakan 2 electro motor. Combustion engines hanya memutar genset"

"Hydrogen cell dari lempeng kaca membutuhkan curahan cahaya matahari penuh. Lahan pertanian adalah tempat ideal. Hydrogen yg dihasilkan diikat oleh graphene buckypaper dalam tabung kapsul. Meski tekanan rendah tapi density 20% dari hydrogen cair. Traktor tinggal mengganti kapsul bila hydrogennya habis
Storage hydrogen ini akan melepas hydrogennya bila diberi tembakan electron dari magnetron kecil. Hydrogen yg terlepas dikonversi menjadi listrik dlm fuel cell. Ini masih minus oksigen untuk tukar ion. Sy masih belum tahu mengadopsi cara menyimpan oksigen seperti hydrogen. Karena listrik baru terbentuk bila ada keduanya. Membrane tukar ion fuel cell masih sangat mahal. Karena baru asahi yg membustnya
Membrane tukar ion terbuat dari polyolefin dan nanopartikel platina. Selama blm bisa memproduksi sendiri, bahan ini berkontribusi cost 86% pada fuel cell"

Teknologi yg masih menginjak bumi adalah mesin bio diesel. Sisipkan tanaman sawit dan pohon jarak di batas kebun. Setorkan buah sawit atau jarak ke kelompok tani yg ditunjuk mengolah bio diesel dgn mesin yg sdh sy ulas di atas. Tdk perlu banysk cingcong timbang buah dan pulang bawa bio solar siap pakai sekaligus bawa minyak goreng untuk memasak, margarine dan sabun colek untuk mencuci
Kalau biodiesel yg dipilih, fertilizer cell yg harus dipilih. Tampung limbah toilet dan busukan daun dalam kolam kecil. Alurkan ke fertilizer cell dgn coating katalis CuPd. cemaran organik NO3 , NO2. akan dikonversi menjadi NH3 yg setara dgn urea atau za cair"

" Pupuk slow release itu green fertilizer. Urea dan ZA itu banyak terbuang sia-sia terbawa air hujan. Mencemari tanah dan perairan"

"Fiksasi nitrogen dari udara bebas bisa dilakukan oleh bakteri dan tanaman berbintil yg mengandung bakteri. Padahal kilatan geledek adalah pabrik amoniak yg sdh Allah SWT siapkan di bumi sebelum bakteri tersebut diciptakan"

"Pikniklah ke kebun raya bogor. Lihatlah pohon besar sebesar kerbau. Daun yg jatuh selalu disapu petugas. Bakteri tdk akan hidup karena permukaan tanahnya ditembok. Pohon itu mendapatkan pupuknya dari air hujan yg mengandung NH3. Waktu sy SD pohon itu baru sebesar kambing. Skrg sdh sebesar kerbau"

"Ahli plasma meniru fiksasi nitrogen menjadi NH3 dgn cara membentuk precusor bebas H yg displitting dari air. Dlm suasana plasma direaksikan dgn Nitrogen udara bebas. Sedikit NH3 TERBENTUK..Ahli nano menyederhanakannya dgn katalis base iron, air dan cahaya matahari
Ingat!! NH3 = PUPUK UREA
Pupuk urea sintetis itu dibuat dari gas methane dan nitrogen udara bebas. Emisi carbon yg dihasilkan sangat dahsyat. Penyumbang gas rumah kaca dan pemanasan global."

" Mengolah kelapa dgn base kopra dan cara psnas. Lemak jahat yg dihasilkan
Padahal asam lemak laurate yg belum terkena panas adalah peluruh kolesterol yg nikmat rasanya
Organisasi food ingredient pd tahun 2014 memutuskan bahwa susu kelapa yg diolah tanpa menggunakan panas adalah makanan terbaik ke 2 di dunia. Harus segera diproduksi untuk menekan kematian 6 juta orsng di USA karena kelebihan kolesterol dan gagal jantung"

" Yg no 1 adalah virgin olive oil minysk zaitun
Terbaik ke 3 adalah super juice sayuran kale. Tinggi lutein dan kalsium
Lutein untuk kesehatan mata"

" Ada 5 manfaat tebu
Gula sukrosa / gula pasir (pangan)
Gula fruktosa (pangan ,farmasi)
Molasis (etanol, msg)
Policosanol (farmasi)
Biomass (energi)
Import raw sugar 2,3 juta ton sama dengan menghilangkan 4 yg lain dan menghilangkan kesempatan lapangan kerja"

" Susu kelapa berasal dari daging kelapa muda dan tdk disaring.. Digiling terhalus dgn alat khusus dan disterilkan tanpa panas"

"Kapitalis berlindung di balik dinding yg kokoh. Tetapi sesungguhnya mereka bercerai berai. Sesudah membaca uraian sy, pasti anda melihat banyak celah untuk mengalahkannya"

"Semua mesin baru ditemukan tahun 2014. Sy mengajak kemandirian diawali dari membuat mesin. Kebetulan mesin ini tdk disukai kapitalis"
