Tougher, Lighter Wind Turbine Blade

Written by , on October 10, 2011

Marcio Loos, a post-doctoral researcher at Case Western Reserve University, has built a prototype wind turbine blade that is substantially lighter, tougher and more durable than currently used blade materials. Working on his own at weekends, Marcio Loos built a polyurethane blade reinforced with carbon nanotubes. Carbon nanotubes are lighter per unit of volume than […]  Read more »

Storing CO2 as Limestone

Written by , on October 10, 2011

A group of Icelandic and American scientists are experimenting with a different way of storing carbon dioxide underground. They are planning to dissolve carbon dioxide in water at high pressure and inject it into basalt formations at a depth of 400 to 800 metres. They expect that the liquid will permeate through pores in the […]  Read more »

Solar Cell Efficiency Boosted by Bouncing Light

Written by , on October 10, 2011

The American Institue of Physics has reported that engineers at the University of Minnesota have improved the efficiency of dye-sensitised solar cells by as much as 26% using a design which sends light ricocheting through layers of microscopic spheres. Dye-sensitized solar cells are made of titanium dioxide, a photosensitive material that is less expensive than […]  Read more »
