Sand as the solution to the world’s energy woes? Or, more precisely, silica? The Sahara Solar Breeder Project is a plan by universities in Japan and Algeria to provide 50 percent of the world’s electricity by 2050.

How?

RoseStreet Labs CreatesTriple-Layered Solar Panel Catches Full Solar Spectrum

MultiLayer-Solar-Panel-3

RoseStreet Labs multi-layer solar panel.

Solar panels are a great technology, yanking free energy out of the air in non-polluting way. But unfortunately, they generally only catch about 15% of the suns rays, making them painfully inefficient. Now a new kind of panel aims to bump that up.

Ultracapacitors Could Offer The Greenest Way Of Powering City Buses

ultracapacitor

A U.S.-Chinese venture is out to prove the benefits of quick-charge buses.

Municipal transit agencies have tried to reduce the carbon footprint of their bus fleets using a range of options over the years, from biofuels and hydrogen to batteries and hybrid-electric diesel. Now a Chinese company and its U.S. partner say that ultracapacitors could offer the greenest and most economical way of powering inner-city buses.

Windbelt: Small-Scale Wind Power To Help Power Third World

 Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don’t scale down well-there’s too much friction in the gearbox and other components. “With rotary power, there’s nothing out there that generates under 50 watts,” Frayne says. So he took a new tack, studying the way vibrations caused by the wind led to the collapse in 1940 of Washington’s Tacoma Narrows Bridge (aka Galloping Gertie).
