Japan Has A Plan To Start Using Space-based Solar Power By The 2030s

In the wake of the Fukushima disaster, Japan has doubled its efforts to find a viable alternative to nuclear power. An updated proposal from the Japan Aerospace Exploration Agency (JAXA) seeks to solve the island nation's energy woes — and it's the much vaunted scifi-like idea of building an orbital farm. » 4/30/14 3:30pm 4/30/14 3:30pm

Judge finds solar power more cost-effective than natural gas

One of the big questions for the twenty-first century is what our biggest source of energy will be. Many are betting on natural gas, because it's cheap and plentiful. Unfortunately it emits dangerous carbon into the environment. The sustainable alternative is solar, but that was deemed too expensive — until now. » 1/08/14 12:14pm 1/08/14 12:14pm

How space-based solar power will solve all our energy needs

Humanity's demand for energy is growing at an astonishing rate. Combine this with an ever-dwindling supply of fossil fuels, and it becomes painfully clear that something innovative and powerful is required. There's one high-tech proposal that holds tremendous promise — an idea that has been around since the late… » 11/28/12 10:46am 11/28/12 10:46am

How a new kind of "black silicon" is revolutionizing solar cells

Black silicon solar cells are a relatively new technological advance that allows for the absorption of light in the infrared spectrum — about 25% of incoming sunlight. These cells are capable of pulling in an incredible 99.7% of the light that hits their surfaces, compared to traditional cells which absorb 95%. And… » 10/11/12 2:30pm 10/11/12 2:30pm

MIT's "artificial leaf" turns sunlight into storable fuel

Take a look at this video. See the little bubbles racing to the water's surface? What you're looking at is an "artificial leaf," unveiled yesterday by a team of researchers at MIT. On either side of this leaf are specially-designed catalysts that, with the help of a little sunlight, allow it to convert the water that… » 9/30/11 4:13pm 9/30/11 4:13pm

Solar-powered hornet is the Superman of the animal kingdom

Plants use photosynthesis to turn sunlight into energy every single day. This ability appeared to be completely unknown in the animal kingdom, leaving the living solar battery that is Superman as the only animal to ever harness the sun's rays for power. But now we've discovered that a type of hornet is doing its own… » 2/13/11 3:00pm 2/13/11 3:00pm
