Finnish nuclear reactor 'may be seven years late'
Finnish electricity company TVO said on Monday that an EPR nuclear reactor being built by Areva and Siemens may not be ready until 2016, contradicting Areva's claims that it would be completed in 2014.
All-terrain technology for developing countries
EPFL is launching "EssentialTech," a unique program in which engineers will in particular produce medical devices custom-designed for the difficult conditions encountered in developing countries.
Engineer designs self-powered nanoscale devices that never need new batteries
(Phys.org)—It's relatively simple to build a device capable of detecting wireless signals if you don't mind making one that consumes lots of power. It's not so easy to design energy-efficient devices that ...
Fujifilm breaks record with thermoelectric material
'Invisible' particles could enhance thermoelectric devices
Thermoelectric devices—which can either generate an electric current from a difference in temperature or use electricity to produce heating or cooling without moving parts—have been explored in the laboratory ...
Scientists develop new materials for board-level photonics
Today at the Photonics West conference, Dow Corning and IBM scientists unveiled a major step in photonics, using a new type of polymer material to transmit light instead of electrical signals within supercomputers ...
Hydro beats nuclear and coal, beats oil and gas
Researchers in Italy and the UK have reviewed the economic, social and environmental impact of hydro, coal, oil, gas and nuclear power. Each has its advantages and disadvantages, but of these conventional electricity generation ...
Fukushima operator TEPCO triples net loss forecast
Fukushima nuclear plant operator TEPCO on Monday slashed its outlook for the fiscal year to March, warning it expected to lose about $1.29 billion or almost three times an earlier estimate.
New Fukushima pictures show wreckage of plant
The shattered remains of a reactor building loom against a lowering sky, smoke or steam pouring from a gaping roof in the days after a huge tsunami smashed into Japan, crushing a nuclear power plant.
Nuclear safety chief quizzed over Fukushima
