EEStor claims that it can store 10 times more power with a barium-nitrate ultracapacitor than can be stored with a lead-acid battery. They also claim that due to the nature of capacitors, it can be completely recharged in 10 minutes. This translated to an electric car that can drive for 500 miles on about $9 worth of electricity. EEStor claims that they will be shipping the new ultracapacitors to ZENN motor within the year on an exclusive contract.

Before you get too excited, one of the fine Boing Boing users posted this little cautionary tale. He thinks that while such a break through would be revolutionary, it would be very, very revolutionary. In his words, "If this pans out it will be a truly amazing feat, but because it's such a massive improvement in an area that many folks have been plowing at for a while, these initial blurbs should be taken with a pretty coarse grain of salt."
