RE: HUGE

Comment comment by starm_ on 04 August 2006

I agree, a breakthrough in ultracapacitors would change the world. Of course this all depends on how small and cheap they can make them, but, if they could get the power density and price of batteries but with the indefinite lifetime of standard capacitors, it would replace oil altogether, it would drastically change the transporation industry, the energy industry, the electronics industry, heh, basically anything that can run on electricity. It would make the use of sustainable energy much more practical as we could store solar and wind energy for when its not windy/sunny.

Although, I suspect there'll be some hurdles. Either, using the nanomaterial will make the capacitors more fragile and make their duration more like that of batteries or the smallness of the insulation will result in big leak currents and they will discharge when left alone. But hey, never know.

I wonder if there is a theoretical limit to the power density capacitors can acheive?

Heard of this? by romanizzo :: NR6

Steorn, a small hi-tech firm in Dublin, seems to have discovered some new and exciting power-device. Scientists are skeptical, however. The technology uses travel through a magnetic field to create energy, which, as we all know, would violate the laws of physics.

It would be pretty cool though, wouldn't it?
