Ancient effect harnessed to produce electricity from waste heat

A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind ...

Nanocrystal-coated fibers might reduce wasted energy

(Phys.org) -- Researchers are developing a technique that uses nanotechnology to harvest energy from hot pipes or engine components to potentially recover energy wasted in factories, power plants and cars.

Graphene battery demonstrated to power an LED

(PhysOrg.com) -- Scientists in Hong Kong have reported, in ArXiv, their experiments to make a graphene battery that they say generates an electrical current by drawing on the ambient thermal energy in the solution in which ...

Solar-thermal flat-panels that generate electric power

(PhysOrg.com) -- High-performance nanotech materials arrayed on a flat panel platform demonstrated seven to eight times higher efficiency than previous solar thermoelectric generators, opening up solar-thermal electric power ...

Controlling the interaction between light and matter

(PhysOrg.com) -- "One of the most exciting things about this is that it gives us nice, clean control over the interaction between light and matter," William Kelly tells PhysOrg.com. "Our technique has the potential to give ...
