Energy storage in miniaturized capacitors may boost green energy technology
"Supercapacitors" take the energy-storing abilities of capacitors (which store electrical charge that can be quickly dumped to power devices) a step further, storing a far greater charge in a much smaller ...
'Superlens' extends range of wireless power transfer
(Phys.org) —Inventor Nikola Tesla imagined the technology to transmit energy through thin air almost a century ago, but experimental attempts at the feat have so far resulted in cumbersome devices that ...
Cape Wind, Siemens agree to Siemens turbines for offshore wind farm
A new material for solar panels could make them cheaper, more efficient
A unique solar panel design made with a new ceramic material points the way to potentially providing sustainable power cheaper, more efficiently, and requiring less manufacturing time. It also reaches a four-decade-old ...
Japanese firm proposes LUNA RING to send solar energy from moon to Earth
Super-thin membranes clear the way for chip-sized pumps
The ability to shrink laboratory-scale processes to automated chip-sized systems would revolutionize biotechnology and medicine. For example, inexpensive and highly portable devices that process blood samples ...
