The following sentence alone is worth reading the entire lengthy article (link below).
An Austin-based startup called EEStor promised "technologies for replacement of electrochemical batteries," meaning a motorist could plug in a car for five minutes and drive 500 miles roundtrip between Dallas and Houston without gasoline.
And in case anyone else is interested, Toronto-based ZENN Motor Co. (those smart guys) has already licensed EEStor's invention. The secret sauce lies in an ultracapacitor which can charge quickly like a capacitor, but has greater capacity like a battery.
Naturally there are doubters, since EEStor hasn't produced a final product yet. However, if this turns out to be true, it could have serious implications. Think about laptops, cameras and other electrical products that utilizes batteries. Not only could they last longer, but they'll charge faster too. And hopefully batteries will really become obsolete.
