Alternative Energies Update

A new prototype capacitor stores power as densely as a supercapacitor, but delivers it at speeds comparable with electrostatic capacitors:

"The resulting capacitor can deliver energy at a speed typical of electrostatic capacitors, at a rate that would allow a single kilogram to deliver one megawatt of power – enough to power 10,000 100-watt light bulbs. It can also store energy as densely as a supercapacitor, with 1 kg holding 2500 joules.

"Our primary target [for this technology] is as part of a hybrid battery-capacitor system for electric cars," says Rubloff. "But there are many [potential] small scale applications, [including] better electrical storage systems for cellphones or laptops.""
