gtada writes: A story published on Physorg.com states 'Scientists from Spectrolab, Inc., a subsidiary of Boeing, have recently published their research on the fabrication of solar cells that surpass the 40% efficiency milestone — the highest efficiency achieved for any photovoltaic device. Their results appear in a recent edition of Applied Physics Letters.' How much longer until we all have paneled roofs?
