Tag Archives: solar thermal Scientists at Airlight Energy have
joined IBM and the Swiss universities, ETH Zurich and Interstate
University of Applied Sciences, to develop an affordable
photovoltaic system that is capable of concentrating sunlight
2,000 times onto hundreds of one centimetre square PC cells –
yielding high efficiency at low cost. The system uses a large
parabolic dish made from a multitude of mirror facets. The dish
is attached to a tracking system that determines the best angle
based on the position of the sun. Once aligned, the sun’s rays
reflect off the mirror onto triple-junction PV chips. On
average, each chip can … Continue Reading Mark Simpson and Ari
Glezer at Georgia Institute of Technology in Atlanta have
developed a new way of driving a wind turbine using the vortex
effect which produces whirlwinds and tornados. When there is a
temperature difference between hot air close to the ground and
cooler air just above it, the hot air rises and cool air falls.
This causes convection currents
