Yeah, I can't really think of anything to write about today, so I'll just pass on a link and go.
EEStor Issued a Patent For Its Supercapacitor
This is huge news for electric cars. The capacitor they're describing stores about as much energy as the battery for the Tesla Roadster, but weighs a fraction as much and can be charged in a few minutes. If they can actually mass-produce these things, then we're in for some interesting times.
(Personally, though, I'm more interested in whether or not they can scale it down too - laptop batteries, for instance, could benefit tremendously from something like this.)
