Air seeps through these cracks, causing your home to lose 30 to 40% in extra heat in the winter and cooled air from your air conditioner [...]
Electricity can be generated by many different means. Solar panels, wind turbines, hydroelectricity, natural gas, coal, and geothermal vents are many of the ways we generate electricity. But now, David Carroll, a nanotechnologist from Wake Forest University has developed a thermoelectric fabric he calls power felt that generates electricity from heat or movement. The fabric [...]
