Hydrovolts tap canal currents for 12 kW of power apiece

Hydro 456789

Powerful new power options.

Irrigation canals are the blood vessels of agriculture, delivering water throughout America’s farmland. Pretty soon, they may well deliver a bit of electricity too, thanks to the Hydrovolt micro-generator.

The Hydrovolt C2, designed and built by the same-named Washington state company, is a compact car-sized device that sits on a irrigation canal’s floor and utilizes the steady, uninterrupted flow of water to power its turbine, which is situated perpendicular to the flow, like a paddle boat wheel. As the wheel turns, it cranks an on-board generator that produces a charge. The device is neutrally buoyant so it can generate power on the water’s surface as well, without impeding the flow or affecting the water quality.

‘Blackest’ solar cell ever absorbs 99.7% of all light

Scientists create blackest silicon solar cell.

Scientists at Natcore Technology have created a black silicon solar cell with an average reflectance of 0.3%, making it the “blackest” solar cell ever designed. Natcore’s development offers a tenfold decrease in reflectance over the solar spectrum. The result is an increase in energy efficiency that could help solar power compete even more effectively with traditional fossil fuels.

Creating liquid fuel with electricity

isobutanol_bioconversion

Researchers have generated isobutanol from CO2 using a genetically engineered microorganism with solar electricity the sole energy input.

Electric vehicles have come a long way in the past decade, but they still have many disadvantages when compared to internal combustion engine-driven vehicles. The lithium-ion batteries that power electric vehicles have a much lower energy storage density when compared to liquid fuel, they take longer to “refuel,” and they lack the supporting infrastructure that has built up around conventional vehicles over the past century. Now researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a process that could allow liquid fuel to be produced using solar generated electricity.

Chevron admits oil leak in Brazil hasn’t stopped

When will the spill stop?

Things just keep getting worse for Chevron. First, a deepwater drilling mishap off the coast of Brazil last month caused thousands of barrels of oil to spill into the Atlantic, which only after some dodging did Chevron take responsibility for, followed by Brazil’s petroleum agency deciding to suspend the company’s drilling rights altogether. And then there are the fines which could end up costing Chevron close to $100 million. But lo, it get’s worst yet. Today, the oil giant admitted that the situation is far from resolved as many had assumed. That’s right, the leak continues, and Chevron’s not sure when it can be stopped…

Nanoparticle batteries could make technology like solar and wind power more practical

wind power

Large batteries could be used for storing excess power from the electrical grid for future use.

New Stanford University research could point the way to large-scale, long-lasting power grid batteries. These kinds of batteries would be especially useful for making technologies like solar and wind power more practical, allowing vast amounts of storage to be stored for periods of time in which the skies are calm or overcast.

Google drops ‘Renewable Energy Cheaper than Coal’ research project

Did Google give up on the planet?

Google is quite a big proponent of renewable energy. They have made all kinds of investments in wind, solar, geothermal, etc. Some are to generate clean energy for their own needs, others are more akin to financing deals to help big wind and solar farms get built. In any case, it is very commendable work and if more big corporations had the long-term vision of Google, the world would definitely be in better shape.

But sadly, one of their most promising clean energy projects has just gotten the axe. Renewable Energy Cheaper Than Coal which was launched in 2007 via the Google.org Foundation, aimed to drive down the cost of renewable energy via R&D efforts until it was cheaper than coal, the magic point at which adoption would reach escape velocity…
