New device stores electricity on silicon chips
(Phys.org) —Solar cells that produce electricity 24/7, not just when the sun is shining. Mobile phones with built-in power cells that recharge in seconds and work for weeks between charges.
World's largest particle detector IceCube detects first high-energy neutrinos from the cosmos
The IceCube Neutrino Observatory, a particle detector buried in the Antarctic ice, is a demonstration of the power of the human passion for discovery, where scientific ingenuity meets technological innovation. ...
New highly efficient thermoelectronic generator
Through a process known as thermionic conversion, heat energy—such as light from the sun or heat from burned fossil fuels—can be converted into electricity with very high efficiency. Because of its promise, ...
Wireless device converts 'lost' energy into electric power
Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar ...
Ivanpah solar plant in California starts energy feed to grid
Scientists propose quantum wells as high-power, easy-to-make energy harvesters
Ambri liquid metal battery: Prototype deployment set for 2014
Power from the sea? Triboelectric nanogenerator extracts energy from ocean waves
(Phys.org) —As sources of renewable energy, sun and wind have one major disadvantage: it isn't always sunny or windy. Waves in the ocean, on the other hand, are never still. American researchers are now ...
Scientists grow ultrahigh-purity carbon nanotubes
Researchers shed new light on dark energy, cosmic speed-up
In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion.
Capturing wasted electricity with triboelectric generators
(Phys.org) —With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs – with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps ...
Researchers claim to have discovered why warm water freezes faster than cooler water
Experts say nuclear power needed to slow warming
Some of the world's top climate scientists say wind and solar energy won't be enough to head off extreme global warming, and they're asking environmentalists to support the development of safer nuclear power ...
