"It's a paradigm shift" - EEStor's Ultracapacitor

Someone quietly beat them to the punch...

Also the 440v US power mains can deliver up to 50 amps before blowing a breaker, so using resistance and a step down transformer people should be able to get a charge in the garage. The trick will be using high farads at lower voltages. example: 125V-3000F cap bank charging off the grid @ 125v and 0.01 Ohms resistance, the cap bank would take about 2.5 minutes to charge and have a maximum power dissipation of 1,562,500 Watts. That sounds like quite a efficient electric scooter ride to me...

I'm seriously considering buying a few of these 2.7V@3000F ultra caps this week, but I would need the help of some of our electronics gurus to design some of the the needed electronics. I'm thinking 5 caps in series for 13.5V@3000F. Anyone interested in starting a cooperative EV thread? We would need to design a self regulating charging system, and a POT controlled discharge system. Maybe even a regenerative braking system in the future... Anyone interested? I would really like to have a 20 horse electric car out on the road some day soon! Or a one horse electric bike at the very least!

Well lets see,
I?m not sure if this calculation is right but,
http://www.answers.com/topic/watt-hour?cat=technology
52220 watt hours * 3.413 to get Btu /  2000Btu per pound TNT= 89.1 Lbs TNT.
(52220 *3.413) / 2000

Maybe not the most fun car?

You have to divide the max watts by 3600 to get Wh's...
434Wh for the bank I described... Not quite a stick of dynamite yet.

What are the size of this capacitor?

google: "maxwell ultra cap"

They have caps and modules for sale now, and the caps I'm looking at are rated for 2.7V@3000F...
