Los Angeles Mayor Antonio Villaraigosa talks about being green in uneasy economic times, biking with his buddy Lance Armstrong, and asking China to help fund his city’s new transit system.
American solar-panel manufacturers have complained that the Chinese are crushing them with underpriced, over-subsidized panels -- and now the U.S. Commerce Department officially agrees.
Now you can dump energy waste just by, well, taking a massive dump. Green tech company OriginOil is working on a project that uses toilet wastewater as a way to heat apartment buildings. OriginOil, a start-up based in Los Angeles, CA., has begun a pilot of its urban algae farm concept at the La Défense complex near Paris. Wastewater from buildings nourishes algae growth; algae is processed to make heat. The company is attempting to prove that integrating algae production into large building complexes will help bring them closer to net zero.
It's still in the "so crazy it just might work" stage, but microalgae-powered lamps could absorb a ton of carbon from the air every year.
Nearly 100 million Americans could install over 60,000 megawatts of solar at less than grid prices – without subsidies – by 2021. That's the takeaway from a new report by John Farrell of the Institute for Local Self-Reliance.
Aquion specializes in making large batteries, cheaply. They don’t look like much -- they live in a former TV factory outside Pittsburgh, and you'll probably never buy any of their products.
Maggie Koerth-Baker, science editor at BoingBoing, has written a book. Here’s the basic idea: In America at least, if we want to get anything done on clean energy, we have to divorce it from conversations about climate change.
Nathan Myhrvold responds to follow-up questions about his paper that found that the transition to carbon-free energy must begin immediately.
“Flow” batteries, i.e. batteries filled with a liquid electrolyte that can be pumped out and replenished, have the potential to transform the process of charging an electric vehicle into something that more closely resembles filling it up with gas.
