Scientists at Ohio State University claim to have inadvertently discovered a new solar cell material that could signify a massive breakthrough in solar technology. The new material, the scientists suggest, is capable of absorbing all of the sun’s visible light energy, translating into the potential of almost 100% efficiency. The two major (and related) drawbacks to solar technology have been cost and efficiency. Average photovaltaic panels in commercial use today hover around the 20% efficiency mark. While OSU scientists caution that commercial application of this new discovery is still years away, the mere suggestion of nearly 100% efficiency is remarkable. The researchers found the new material “not only fluoresces (as most solar cells do) but also phosphoresces…[where the electrons can] be ’siphoned off’ as electricity over 7 million times longer than those generated in fluorescent state.” We’ll be watchcng this space with great interest to see if this discovery is as groundbreaking as the OSU team claims.

One of our readers sent us this note: “Hey guys- I was at the Boulder-Kansas State game this past weekend and was impressed by Ralphie’s Green Stampede…check it out!”

Thanks, we did, and we’re impressed as well. Ralphie’s Green Stampede is Colorado University-Boulder’s initiative towards a zero-waste football stadium. With this sustainability drive, named for the school’s buffalo mascot, university officials claim it’s the first of any major collegiate and professional sports programs to undertake such an ambitious green initiative. Stadium officials anticipate recycling or composting at least 90% of all waste generated from events at Folsom Field by season’s end. Student volunteers collect and sort recyclables and compostables at 50 trash drop off locations throughout the stadium, with campus ROTC units providing additional assistance. Sponsors, including White Wave Foods, are helping to offset 100% of the electricity used during the games. The stadium provides free valet parking for all fans arriving on bicycles, in an effort to promote lower carbon emissions outside the stadium as well.

The school’s mid-season review of the program indicates a resounding success.
