Solar panels made many times cheaper with four times greater efficiency

The Concentrated Universal Energy Solar System (CUESS) to be commercialized by Technique Solar As regular readers will know, we cover more than our fair share of breakthroughs promising next-generation super-efficient solar cells. Everything from growing photovoltaic crystals, applying special coatings or using carbon nanotubes teases us with cheaper, more efficient solar energy – eventually. In […]

US$3 LED light bulb lasts 60 years, maybe this will solve which bulbs to buy

February 2, 2009 Cambridge University researchers have developed cheap, light-emitting diode (LED) bulbs that produce brilliant light but use very little electricity. They will cost just GBP2 (USD2.80) and last up to 60 years. The gallium nitride based bulbs are 12 times more efficient than conventional tungsten incandescent bulbs and three times more efficient than […]

Making kelp a viable source of biofuel just by applying heat

BIO-FUEL FROM SEA SUGAR KELP Sugar kelp yields a lot of bio-oil – if you put the heat on Biofuels may indeed offer a greener alternative to fossil fuels, but they do raise at least one concern – crops grown as biofuel feedstock could take up farmland and use water that would otherwise be used […]
