...Many have questioned EEStor's claims, pointing out that the high voltages needed to approach the targeted energy storage would cause the material to break down and the storage device to short out. There would be little tolerance for impurities or imprecision--something difficult to achieve in a high-volume manufacturing setting, skeptics say.

But Weir is dismissive of such reactions. "EEStor is not hyping," he says. Representatives of the company said in a press release that certification data proves that voltage breakdown of the aluminum oxide occurs at 1,100 volts per micron--nearly three times higher than EEStor's target of 350 volts. "This provides the potential for excellent protection from voltage breakdown," the company said....

This as I see it is the one shot there is at eliminating the entire petroleum economy without returning to the middle ages.

@gungasnake,

How you planning on charging all those capacitors gunga?

@parados,

I don't know either, but probably the same way we are going to be charging all those electric cars we keep hearing about. Actually, the theory is that all this stuff is going to be charged during off peak load hours. I've got some doubts on where the electricity is coming from too, but they apply to batteries as well as super capacitors.

The thickness of the dielectric @ one micron is stunning given the applied voltages, the theory of using capacitance as opposed to electrochemical (in principle) is sound.

In British Columba we have more electrical energy than we can use (in fact we sell to the US grid) and it's virtually all from hydro-electric.

@Chumly,

Well, I used to consider a computer's hard drive to be a passing fad, ending when it was discovered that the tolerances couldn't be maintained in mass production.

now where exactly is the flux capacitor in that thing?

@roger,

It’s not the tolerances per se, as to maintaining high levels of electrostatic charge for a given area, it's the ability of the dielectric (and the plates) to withstand what amounts to stunningly high physical forces.

Remember I said "given the applied voltages".

@Chumly,

I understand what you are saying. I'm just pointing out that what seemed impossible 20 years ago. By understand, I don't mean I understand the precise problem, just that it's a high technological hurdle.

Glad to see you came back, by the way.

@roger,

Always a pleasure to chat with you, I have three weeks off and there is a ton of snow, so I'm just reviewing lesson plans and pestering the wife and stuff.

I teach:

C = Q/V
W = ½ QV
C = er e0 (A/l)
(1/C) = (1/C1) + (1/C2) + (1/C3) series
C = C1 + C2 + C3 parallel

and stuff.......
