Electricity produced from waste heat
Thermoelectric materials can generate electricity from waste heat which escapes through vehicle exhaust pipes, industrial equipment, and computer chips, but so far the materials have not been efficient and have been too expensive to be widely used.31 Mar 2009
Thin films enhance thermoelectric energy harvesting
Nextreme has recently developed a thin-film thermoelectric generator (eTEG™) that converts heat directly into electricity delivering power generation densities greater than 3W/cm2.2008

Metamaterials: Printing the cloak of invisibility
Physicists no longer say that the invisibility cloak of Harry Potter, the vanishing car of James Bond or the Invisible Man are an impossibility. It may be possible to make things invisible by putting a thin layer of a specially patterned material in the way.17 Mar 2008

Scientific Challenges in Sustainable Energy Technology - DSSC
DSSC photoelectrochemical solar cells that mimic the action of chlorophyll in nature are already being commercialized. They are ten times as efficient as the version met in nature and they are more tolerant of reflected (polarized) light, light at narrow angles of incidence and low levels of light than most alternatives.
