The largest solar rooftop on the planet is being installed by none other than American automotive giant General Motors. The company announced on Tuesday that it plans to install the biggest rooftop solar photovoltaic power installation on Earth on top of its car assembly plant at Figueruelas, Zaragoza, Spain. The installation will cover over 2 million square feet of space with renewable electricity producing photovoltaic cells on 85,000 solar panels.

Partnering with Clairvoyant Energy, Veolia Environmental and the Government of the Spanish state of Aragon, GM will produce over 12 MW at peak output on the Zaragoza rooftop using United Solar Ovonic thin laminate panels - enough to power over 4,500 households per year. GM already operates two of the largest solar power installations in the United States at its plants at Fontana and Rancho Cucamongo, California. The latter facility powers 50% of its electricity by the solar installation.

Solar Powered Soldiers Wear Uniforms with Built-In Batteries

The average U.S. soldier needs 88 AA batteries for a five-day mission. That’s a lot of weight to haul around, but a new high-tech fabric that incorporates solar powered batteries into cloth could go a long way towards lightening that load, according to NPR’s Living On Earth:

“these threads are a fraction the thickness of a human hair. When they’re made out of battery electrodes and photovoltaic and fuel cells and then stitched together, they constitute a fabric that captures and stores energy while it’s worn.

Florida researchers designed the machine for the military, but as Living On Earth’s Mitra Taj noted:

The new technology might help in civilian life too, boosting efforts to make environmentally friendly power sources that multitask”imagine a jacket that keeps you warm while charging your cell phone.

Nice to see the military-industrial complex, which once brought us Agent Orange, being an agent of green.
