Super battery technology

If this were to be true, it would mean a big change in the way we think about batteries.

EEStor Capacitors- "This could change everything"

From the article: "Among EEStor's claims is that its 'electrical energy storage unit' could pack nearly 10 times the energy punch of a lead-acid battery of similar weight and, under mass production, would cost half as much.

It also says its technology more than doubles the energy density of lithium-ion batteries in most portable computer and mobile gadgets today, but could be produced at one-eighth the cost.

If that's not impressive enough, EEStor says its energy storage technology is 'not explosive, corrosive, or hazardous' like lead-acid and most lithium-ion systems, and will outlast the life of any commercial product it powers. It can also absorb energy quickly, meaning a small electric car containing a 17-kilowatt-hour system could be fully charged in four to six minutes versus hours for other battery technologies, the company claims."

See also this post on why we will likely never have electric cars that recharge in four minutes.

It would take a long time to recharge cars at home, but couldnt we just build recharge stations just like gas stations that could supply the current needed to charge the cars fast?
Hi Marshall, thanks for the link. Nice blog.

17kWh at 200V in 6 minutes equals 850 amps. They better have some thick wire going in to those things.

They say they aren't explosive, or "hazardous", but what happens if you short the contacts? Pretty fireworks, that's what, assuming those 850 amps can come back out.
Hi Marshall,

I saw a story on the news the other night about a young guy who created "The Million Dollar Homepage". He said that he was sitting in his room, literally thinking about how to make a million dollars, and decided to make a page full of advertising, charging $1 per pixel. Half jokingly, I searched "how to make a million dollars" and was pleased to find the slides to your great presentation. Your story is interesting and inspiring. I have read Rich Dad Poor Dad and found the slides from your lecture to be an educational and entertaining advocate of that unique style of thinking. Just wanted to say thanks.
You can have some device (perhaps a similar capacitor) recharging at home.

You could simply swap in a new capacitor/battery, if it were made user-friendly and safe to do so, or the device could charge the car's capacitor/battery quickly.
