(Phys.org)—A new study predicts that large-scale power plants based on thermoelectric effects, such as small temperature differences in ocean water, could generate electricity at a lower cost than photovoltaic power plants.
To convert heat into electricity, easily accessible materials from harmless raw materials open up new perspectives in the development of safe and inexpensive so-called "thermoelectric materials." A synthetic copper mineral ...

(PhysOrg.com) -- Among the many applications of flexible thermoelectric materials is a wristwatch powered by the temperature difference between the human body and the surrounding environment. But if you wanted this watch ...
New research has demonstrated that a magnetic uranium compound can have strong thermoelectric properties, generating four times the transverse voltage from heat than the previous record in a cobalt-manganese-gallium compound. ...

(Phys.org)—Photographic film maker Fujifilm has been busy this year at the Nanotech 2013 conference being held in Tokyo. First came news of bendable/roll up speakers. Now the company is showing off a new thermoelectric ...
It's estimated that more than half of U.S. energy—from vehicles and heavy equipment, for instance—is wasted as heat. Mostly, this waste heat simply escapes into the air. But that's beginning to change, thanks to thermoelectric ...
