I cannot remember the numbers exactly but with the current li-poly cells about 80% of the charge occurs in about the first 30 min of the 1 hour charge time. Mike

The 80% charge in 1 minute is very interesting, but need to know how long the other 20% takes and what the discharge curve looks like. Also will need special chargers for these cells. Cost and reliability are the key questions that will need to be answered. As with all technology, it will become more affordable in time and its uses more common. I would give it 2-4 years.

It would make electric vehicles much more practical - since 300+ mi Li-ion cars are already reasonable from the standpoint of range and weight - the last issue is charging speed. I could stand a 10-15m wait to fill up a car. Or added as extra storage in your Prius+ hybrid - store power from your PV array, and get a few gals of gas a day for free (takes about 8kwh to get the equivalent of a gal of gas, you get an average of 4.5hrs of averaged peak power per day for a year here in CA - more in summer, less in winter, but it averages to that). Of course price will be the biggest issue - they'll be more expensive than Li-ion/polymers at first. You'd also think if they can be charged that fast, they could DISCHARGE that fast, too.
