Researchers aim to harvest solar energy from pavement to melt ice, power streetlights

KINGSTON, R.I. — November 9, 2010 — The heat radiating off roadways has long been a factor in explaining why city temperatures are often considerably warmer than nearby suburban or rural areas. Now a team of engineering researchers from the Un…

MIT researchers develop a way to funnel solar energy

CAMBRIDGE, Mass. – Using carbon nanotubes (hollow tubes of carbon atoms), MIT chemical engineers have found a way to concentrate solar energy 100 times more than a regular photovoltaic cell. Such nanotubes could form antennas that capture and focus …
