Scientific research and entrepreneurship in clean energy is alive and well at the ARPA-E Summit.
CNET heads to San Diego for Comic-Con, America's pre-eminent entertainment geekfest.
The DOE's ARPA-E is funding energy research and development but the agency is seeking to engage large industrial companies to bridge the gap from lab to market.
Your guide to the ARPA-E Energy Innovation Summit this week, where startups and research institutions are showing off the latest inventions in cleaner energy.
Altaeros Energies shows how an airborne wind turbine, held in a tethered blimp, can generate power at high altitudes and automatically reattach to its launcher.
Using digital technologies, startup Thermata looks to slash the cost of concentrating solar power plants which is needed to stave off the onslaught from cheaper solar photovoltaic panels.
By pairing biology and photovoltaics, a new "electrofuel" system could build alternative fuels.
Wind startup tests a prototype airborne wind turbine that uses a helium-filled shell to lift a small wind turbine into stronger and steady winds at higher altitudes.
Startup Makani Power clears its first hurdles in building a radically different wind turbine that flies like a kite and captures high-altitude winds.
The U.S. government aims to improve energy production from renewables to oil, but what does that mean in practice? Energy Secretary Steven Chu explains.
A power-hungry world needs clean, reliable energy sources, but the cost of nuclear, and heightened safety concerns from Fukushima, have stalled nuclear's expansion.
