500 Miles on a 5-Minute Recharge?

ctroutwi writes "In the wake of rising gasoline costs there have been plenty of alternatives seen on the horizon. Including Hybrids, Biofuels, fuel cells and battery powered all electric cars. CNN has recently posted a story about a company (EEStor) that plans on offering UltraCapacitor storage products. The claim being that you charge the ultracapacitor in 5 minutes, with approximately $9 of electricity and then drive 500 miles."

I am old enough to remember city streets in places with overhead power lines for this. Its ugly. Why? I get 500 miles on a tank of gas (13.5 gallons and 29 miles to the gallon) so why not just let me pull into a service station, which now takes almost 5 minutes for a full tank, and plug in... charge me $20 for the charge, make the 100% profit ($9 for the elec, $9 profit, 2$ to cover overhead)... I end up better off they end up better off (distribution now done by the existing power lines, no need for trucks) and eventually, when we figure out how to make electricity cleaner (or convert part of of grid to wind or water turbine or whatever) the environment would be better off. Sounds like a win/win/win situtation

what kind of a home has a gasoline pump? i'd imagine there would be special places along the roads that you plug into, just like how it works now.

$9 of electricity is about 100 KWh at national average rates. Passing that in 9 minutes gives you an average rate of 1.2 megawatts. What the hell knid of household has the circuit to handle that?

I would be terrified to even stand near such a fueling station, let alone use one or install it in my home.

Imagine the mortal dread of having your 1.2 megawatt car running low on power during a rainstorm.

For all it's potential energy, at least liquid gasoline is relatively stable and safe. Gasoline car crashes generally only cause explosions in the movies. Unless it's an old Ford Pinto, or a truck being tested on NBC's "Dateline."

The advantage of electricity remains, even if you are still polluting with your power generation facilities.

It is easier to institute stricter pollution control measures at centralized power generation facilities than it is to implement equivalent levels of pollution control in vehicles all over the country. Even very "dirty" methods of producing such power can always be upgraded over time to be less polluting anyways, or possibly even migrate towards emission free power generation. Also, this migration does not have to be instantaneous either, as an incremental change is often much more economical and practical than a single large change anyways. This sort of upgrading would be completely impractical for individual automobile.

Also, it reduces dependancy on foreign oil.
