New York’s urban architect recyclers, LOT-EK, have recently designed a library in Guadalajara made entirely of refurbished airplane fuselages.
U.S. Department of Energy (DOE) Assistant Secretary for Energy Efficiency and Renewable Energy Alexander Karsner today announced that with DOE funding, a concentrator solar cell produced by Boeing-Spectrolab has recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance. This breakthrough may lead to systems with an installation cost of only $3 per watt, producing electricity at a cost of 8-10 cents per kilowatt/hour, making solar electricity a more cost-competitive and integral part of our nation’s energy mix.Here's the +5 slashdot comments.

Hard not to be skeptical, but Richard Branson is developing a clean fuel
It will be called Virgin Fuel, yes! It's not ethanol-based as such, but it'll be a clean fuel. And if we've got it right, it could be a very important breakthrough. We think this fuel will work in cars and trucks and trains within a year. And we're hoping that it might work in commercial jet engines within five years, possibly sooner. So it will be able to work in Virgin Atlantic planes one day.
But it's not just that we thought we should do this to try to save the world and the thousands of species that could die if we don't do it. Unless you can generate cash, it's not going to be successful. With oil prices above $70 a barrel, people want to save on the cost of fuel, and so alternative fuels suddenly make business sense.
