IEA ups wind power target for global electricity by 2050
Scientists unveil energy-generating window
Scientists in China said Thursday they had designed a "smart" window that can both save and generate energy, and may ultimately reduce heating and cooling costs for buildings.
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.
Topological light: Living on the edge
(Phys.org) —Topology—the understanding of how things are connected—remains abstract, even with the popular example of doughnuts and coffee cups. This concept, esoteric as it appears, is also neat because ...
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 ...
