In a survey of brand names dropped in the tweets and facials (is that the right term?) of today's social-networking mavens, Google came out primero, with Apple at #2, and Microsoft at #3. (Blackballed fans would know that Apple is #2 because it's the shit, but anyway...) The funny part is what didn't make the top 10: HP is there, but Dell is not; BMW yes, but Mercedes, nope; I see a Samsung, but I do not see Sony. As unscientific as this study by Sysomos is, it must tell us something. [AppleInsider]

Wired wrote up MIT roboticist Sangbae Kim, father of the gecko-inspired Stickybot. His new plan? To make a robot that looks like a cheetah—and runs as fast as one. Yep, he's saying his carbon-fiber quadruped will hit 70 mph. Trouble is, this is all chalkboard chatter: It'll take 18 months for Kim and his colleagues to whip up prototypes of this evil-looking dude, so we have to wait to find out if he was right or nuts.

NPR today showed off a product that will hopefully soon come free with a donation to listener-supported radio. I say that not just as a fan of listener-supported radio, but as someone who would never specifically buy an NPR-branded radio. It aggregates all of NPR's affiliates under one button, and offers on-demand streams of Terry Gross and other awesome NPR folks, but none of this is exclusive to this device. Charitable notions aside, this makes no more sense than an NBC-branded TV (that also lets me watch Fox). [CNet]

Having spent my whole life in the northern parts of these United States, I have always assumed that it's up to the sunnier parts to get with the solar-power program. At least San Diego sees the logic of this, and is going all in with alternative power. UC San Diego and CleanTECH San Diego are building a smart grid, which puts power back into the system when claimed from solar panels and other alternative sources. The school will produce 3.4 megawatts of renewable energy by next year, while San Diego Gas & Electric pledged to get 33% of its power from renewable sources by 2020. Maybe when they get over 100%, they can share the excess sunlight with those of us stuck in Cloudyville. [Treehugger; Image credit slack12/Flickr/CC BY-NC-ND 2.0]

As a teenager in a rural village in Nepal, Milan Karki knows just how desperately developing countries need an affordable, renewable energy source. But rather than whine about the availability of electricity or the cost of batteries, he sat down and came up with a solution: Low-cost solar panels with human hair conductors.

Solar energy isn't anything new, but solar panels themselves can be pricey to produce due to using silicon. Karki solved the cost issue by using human hair instead since it turns out that Melanin, a color pigment in hair, is a good conductor. Oh, and did we mention that it's cheaper than silicon?

Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months, whereas a pack of batteries would cost 50p and last a few nights.

I don't know why they're selling hair by the kilo, but this idea is absolutely brilliant and I can't wait to see if it turns into something widely used. [Daily Mail]

The new kit—because it may look like a race car but let's be honest, it's a science edu-toy—still comes with the solar panel and hydrogen station so that you can use the sun's rays to convert H2O to H2 and O2. But the car itself now has glowing LEDs, responds to an IR remote, and runs longer and faster with the same amount of fuel. Taking a cue from auto makers and gas companies who release literally green advertisements to convince the public they aren't part of the problem, Horizon decided to change the car's translucent tint from blue to, yes, green. The difference, of course, is that Horizon definitely isn't part of the problem. Only time will tell, however, if they are part of the solution. Meantime, here's a fun Christmas gift for anyone that still has $120 to spend on progress! [Horizon via Gizmag]

When two ceramic semiconductors with different temperatures are connected, an electrical current is produced, creating power, which means that cell phones, laptops, mp3 players and other portable devices can partially recharge themselves.

However, it may take more than 10 years before self-recharging gadgets will be available to consumers, so don't worry — you can still use your laptop as a personal heater for the upcoming winter. [pcadvisor via wired]

For starters, Rock Port only has 1300 residents, which is much easier to power using renewable energy than most places. Wind power currently accounts for 1% of total power consumption, and the US government only sees it providing around 20% of the power needed to run the country in the future. And even for that to happen, turbines need to become dramatically more efficient. But I'm not trying to rain on Rock Port's parade (which I'm sure every eco-freak would have gathered for, had it not added to their carbon footprint). [Science Daily via Popular Science]

The maps are especially important as floating wind farms become more technologically possible. Ocean wind farms have less environmental impact than onshore wind farms and also tend to be more efficient, since winds are stronger over the water and there are no hills or mountains to block a heavy gust's path. Placed in the correct areas, the farms could harvest up to 500 to 800 watts of wind power per square meter.

One area with extremely high winds is located off the coast of Northern California near Cape Mendocino, where northernly zephyrs are deflected to create a local wind jet that blows year-round. Similarly, Tasmania in New Zealand and Tierra del Fuego in South America have the potential to utilize similar jets. [NASA via Treehugger]

The man responsible for Samsø's shift is Søren Hermansen, who after deciding farming wasn't for him, became an environmental sciences teacher, and then a renewable energy expert. Growing up on the island and seeing the impact the people were having on the environment, Hermansen felt he could talk the residents into making some changes. The public response was favorable, and the transformation began. The island now has 11 onshore turbines, a biomass plant, and a straw burning plant, which are invested in by the residents of Samsø, as well as outside, private investors. All the while, this green movement has brought in a constant flow of researchers, scientists and sociologists trying to figure out Samsø's mojo.

And for those in the giant turbine market, I think it's worth noting that giant turbines come with panoramic sunroofs. Not sure about power locks and cruise control, however. [New Yorker]

The device itself weighs less than one pound and it can "convert (or reform) a continuous stream of hydrogen from fuels like gasoline, diesel, vegetable oil, biodiesel, propane, natural gas, even the glycerol byproduct from biodiesel manufacturing" using an "array of microchannels containing patented catalytic sites." There are still major obstacles to overcome (the fact that there is no renewable source of energy to produce hydrogen being chief among them), but InnovaTek still plans on using the $500,000 they secured from a deal with Chevron to aid them in their plans to commercially license the microreactors by 2009.

The project is expected to cost $300 million, and it will form an impressive center piece to Masdar City, which will be a $22 billion development stretching out beyond Abu Dhabi. The Masdar HQ is the very vision of a greener future. In fact, a roof pier will be the first part of the building to be hoisted into place, which will be covered in solar panels that will generate energy for its own construction. The complete structure will encompass some 1.3 million square feet, and we think the term "intelligent design" should now be redefined to accommodate the Masdar HQ's structural plans.

So that's just what PG&E is doing, using manure to power up to 1,200 homes in California. It's all part of new regulations in the state that are to require utility companies to have 20% of their energy coming from renewable sources by 2010. With a figure that high, they need to look outside the standard solar and wind sources.

So how exactly do you turn cow crap into energy? How's a 33-foot-deep pit full of the stuff sound? Get ready to appreciate your desk job a little bit more:

To tap the renewable gas from cow manure, the Vintage Dairy farm first flushes manure into a large, octagonal pit, where it becomes about 99 percent water. It is then pumped into a covered lagoon, first passing through a screen that filters out large solids that eventually become the cows' bedding.

The covered lagoon, or "digester," is the size of nearly five football fields and about 33 feet deep. It is lined with plastic to protect the ground water and the cover, made of high density polyethylene, is held down at the edges by concrete. The digester's cover was sunken into the lagoon on Tuesday, but officials said it would be taut and raised in a few days as the gas collects underneath it.

Weights on top of the digester channel the gas to the small facility where it is "scrubbed" of hydrogen sulfide and carbon dioxide. The end product is "close to 99 percent pure methane" according to BioEnergy Chief Operating Officer Thomas Hintz.

Wind machines were used way back in 200 B.C. by the Persians, who managed to put the wind crunchers to use for grain grinding purposes. Skip a few years ahead, and you have the first Megawatt wind turbine (pictured), which was set up on a hilltop in Rutland, Vermont, and provided power to the local grid during WWII. The turbine was affectionately known as "Grandpa's Knob." Charming. Thanks for attending Wind Turbine Retromodo 101; there'll be a test next week, so get revising. [Live Leak; Wiki]

The goal is to bring the number of solar installations up from 660 to 10,000 citywide over the course of the next 10 years. So what would it cost for you to go solar under the initiative?

For a typical homeowner in San Francisco, installing a 3-kilowatt, rooftop solar electric system costs $24,000, according to Barry Cinnamon, president of the California Solar Energy Industries Association. Between a $4,000 city rebate, a similar $7,000 refund available through the state and a federal tax credit of $2,000, they would be able to get the price down to $11,000, Cinnamon said.

If that amount were underwritten through a city-backed loan, the costs would be spread out over time and eventually recouped in under a decade through lower electricity bills, he said.

The plan would call for massive wind turbines that would reach 850ft in the air to grab the good stuff so each of these generators could produce enough power for 8,000 homes.

Of course, an 850ft turbine is quite visible. And it means that the UK coastline may lose its scenic beauty. There's really no way to have your eco cake and eat it to. That's why we use hamster wheel generators for everything in the Wilson household. You get renewable energy and cuddly friends/an emergency food supply. [timesonline][image]
