According to the witches and wizards at NEC Electronics and Onryoku Hatsuden, their new remote generates electricity when the users clicks on any button. They are planning to see the first production remotes in 2011. [Aiajin via Crunchgear]

It’s only a prototype at the moment (one of many that have come out lately focused on saving energy), which probably explains why it still looks like a child’s toy. Not a good idea when you consider that it sits between the wall outlet and the plug of your gadget. At any rate, PowerZoa transmits details on your power usage to a secure website, where you can use the interface to turn specific devices on or off.

Sooner or later something like this will be widely available, and there will be a mobile phone app that would allow me to control everything. And when that happens, I will be all over it. [Powerzoa via DVICE]

Yes, coconut-shell charcoal plays a key role in a facility which is estimated to turn into a $US10 billion project because for some weird reason the stuff acts like an “environmental sponge” and sucks up helium and hydrogen byproducts like nothing else. Experiments with the Tokamak reactor which is the heart of the ITER facility won’t even start until 2018, but I’m already getting concerned about what’s going to happen to the world supply of coconuts now.

President Barack Obama announced today a $US8 billion federal plant to modernise the United States power grid. $US3.4 billion will come from the government, and the rest will be put up by private companies. In his words:

At this moment, there’s something big happening in America when it comes to creating a clean-energy economy. But getting there will take a few more days like this one, and more projects like this one. Here in this region of Florida, this project will reduce demand for electricity by up to 20 percent during the hottest summer days that stress the grid and power plants,. It will provide smart meters to 2.6 million more customers. And most importantly, it will create thousands of jobs – good jobs, by the way, that can’t be outsourced; jobs that will last and jobs that pay a decent wage.

In my words: About f—king time. We need to modernise the power grid not only for the jobs, but for the long term survivability of the country’s economy. It’s the only way to depend less on other countries, and make production more efficient and competitive.

And it’s not only about using renewable energies. It’s about increasing the efficiency of electricity transport and consumption at the home. That’s why $US1 billion dollars is going to smart meters and other consumer oriented technology, which will make more than five million homes to consume a lot less. Two billion will go to infrastructure to support those meters, and $US400 to modernise power lines, with an additional $US25 million to push for smarter, more power efficient devices.

Do you think this is a lot of money? It seems a lot, especially since it only covers a small part of the grid. But here’s what we are getting in return: $US20 billion in savings during the next decade, plus increasing the reliability of the grid to avoid power outages that cost $150 billion a year.

The structure generates 130 kilowatts of solar power, enough to offset 65,770kg of greenhouse gas emissions annually. There are even charging terminals available for electric cars, but only two can be charged at a time. Seems like a pretty smart way to keep drivers comfortable and harvest some spare energy on the side. [Dvice]

Sony’s Wireless Power Transfer can push 60 watts of electrical energy over almost 20 inches (50 centimetres). That’s a pretty decent distance, especially when they say that it can be extended using passive extender units. In fact, they have already achieved 31 inches in other tests.

They claim that their method—which sounds similar to Intel’s—uses some dharmastastic magnetic resonance, in which electromagnetic energy gets transmitted from one device to another, both sharing the same resonant frequencies.

Sony says that this system offers 80% efficiency, which may get reduced to about a minimum of 60% if there is a misalignment in the frequencies, which needs to be corrected.

I don’t know if this is safe for our bodies or not, but I would like to have it. Even if that requires me not wearing my tinfoil hat while watching the sixth season of Lost. [Sony via i4u]

NPR says that NASA has not made any new Plutonium-238 since the 1980s, instead opting to borrow from Mother Russia. And because they use up to 5kg of the material each year, it would take eight years worth of production to begin satisfying demand again. But the requested $US30 million from Congress is only a start — the full Plutonium-238 production program could cost up to $US150 million.

Because it gets so cold in deep space (reaching absolute zero), spacecraft travelling out that far need a fuel generating a lot of heat, so they can convert that energy to electricity. Plutonium-238 naturally generates a serious amount of heat as it goes through radioactive decay, so it’s often the fuel of choice for these NASA adventures, such as voyages to Saturn and beyond.

According to a Johns Hopkins planetary scientist, NASA has enough Plutonium left to fuel the next Mars Rover mission, and maybe enough to test out some new power generators. After that, they need more scratch for more fuel. [NPR via MIT Tech Review]

Defense Tech’s Bryant Jordan was at the Disneyland of military gadgetry—the Modern Day Marine event at Quantico—and came across this power-generating backpack, which has stepped from prototype to reality. It can generate 40 watts just by walking.

It works great, apparently. The backpack itself is mounted on rails, so it moves up and down when its wearer moves. The movement generates enough electricity to power your gadgets, and the design actually relieves stress from the user. [Lightning Packs via Defense Tech]

The otherwise normal surge protector automatically cuts the power to connected devices after precisely 11 hours of use. (Some engineer at Belkin was clearly tired of working 12-hour days.) But just to make sure you don’t lose work before you save, the Conserve Surge features two always-on outlets alongside its six timer outlets, plus there’s an LED warning light when the electricity is about to be cut.

Priced at $US35, the Conserve Surge isn’t much more than your standard premium surge protector. Then again, if you work long hours, the thing would drive you mad. [Belkin via Slashgear]

Nothing in this world can take the place of persistence, and William Kamkwamba has it in spades. At age 14, while many of us were sneaking out of classrooms, William was struggling to sneak into them — his family was unable to afford the $US80 annual tuition. As is bound to happen to most students, he was caught. But instead of being sent to detention, he was barred from the school. In a show of the driven man he would become, he didn’t allow that to hinder him and instead started spending his days in the local library. While there, he encountered a book called Using Energy:

Using Energy described how windmills could be used to generate electricity. Only two percent of Malawians have electricity, and the service is notoriously unreliable. William decided an electric windmill was something he wanted to make. Illuminating his house and the other houses in his village would mean that people could read at night after work. A windmill to pump water would mean that they could grow two crops a year rather than one, grow vegetable gardens, and not have to spend two hours a day hauling water. “A windmill meant more than just power,” he wrote, “it was freedom.”

This book is what changed his life. And I don’t mean that as an exaggeration. It was truly what made a difference in his life. Because of that book, and the potential he saw in its ideas, William began to build:

William scoured trash bins and junkyards for materials he could use to build his windmill. With only a couple of wrenches at his disposal, and unable to afford even nuts and bolts, he collected things that most people would consider garbage-slime-clogged plastic pipes, a broken bicycle, a discarded tractor fan-and assembled them into a wind-powered dynamo. For a soldering iron, he used a stiff piece of wire heated in a fire. A bent bicycle spoke served as a size adaptor for his wrenches.

Imagine that. A young boy being so motivated by ideas and the sheer need to build something life-changing that he discovered materials and uses for them which most of us wouldn’t even dream of. As Mark Frauenfelder put it:

For an educated adult living in a developed nation, designing and building a wind turbine that generates electricity is something to be proud of. For a half-starved, uneducated boy living in a country plagued with drought, famine, poverty, disease, a cruelly corrupt government, crippling superstitions, and low expectations, it’s another thing altogether. It’s nothing short of monumental.

After completing his first windmill, William “went on to wire his house with four light bulbs and two radios, installing switches made from rubber sandals, and scratch-building a circuit breaker to keep the thatch roof of his house from catching fire”. His project had the attention of village locals early on, but at this point he gained the attention of TED, Technology Entertainment Design, through whom he was introduced to individuals willing to contribute to his plans to “electrify, irrigate, and educate his village, as well as pay his tuition at the prestigious African Leadership Academy in Johannesburg.”

In short: A young man struggled to educate himself, to build something his village needed, and in the end made a difference to the entire locale and gained the education he’d always wanted. Yes, it’s a fluffy, feel-good story with a happy ending. What should you take from the it? Maybe that there’s hope in the bleakest of situations, maybe that your teachers and parents were right about the power of education, maybe just that I’m a sappy bookworm with a soft spot for happy endings. No matter, if you wish to learn more, you can read the recently released The Boy Who Harnessed the Wind, check out William’s blog, or peek at this video from before he ever wrote his autobiography.
