Among the more high risk methods of geoengineering, methods that reflect sunlight away from the Earth to counteract temperature rise are right up there in terms of potential unintended consequences. Well, a new piece of

Another report on another geoengineering method that is likely too risky to try and utterly not cost-effective: Injecting aerosols into the atmosphere to slow warming (which would do absolutely nothing about ocean acidification, by the way).

Some new research looks at the unintended consequences of injecting aerosols into the atmosphere to block solar radiation and cool the planet, finding that doing so could turn skies everywhere into a brighter, whiter, hazier, ugly mess.

Researchers have used abundant and inexpensive materials to create a tandem solar cell that can store solar energy as hydrogen for use at any time of day.

The fuel cell is part of Microsoft's Data Plant project to build a zero carbon data center.

Last week at CES in Las Vegas, Toyota revealed the FCV concept car for the fuel cell vehicle they will be making available next year. I had a chance to see the concept this week at the Detroit Auto Show.

This small hydrogen fuel cell charger promises a week of clean power for your gadgets. But is it ready for prime time?
