NeO4 is harder to make and store but has a lot more energy per pound. If you had a tank full of it, you could get 200MPG out of a Hummer.

I suspect they've misunderstood some basic fundamentals about barium titanate dielectrics. Like their voltage coefficient ! It may simply be a scam. Graham

That's the other side of the equation. Such claims are utter bullshit for a miilion practical reasons like the one you mention. Graham

Which part of "stupid freak" is confusing? he is simply obsessed with h2o2, and will hear of no facts which contradict his lame plan.

Even if such a capacitor existed, Ohm's law, the basic equations for a capacitor and a few calculations say this is bullshit unless you are charging from a power substation with cables as big around as your leg. -- Jim Pennino Remove .spam.sux to reply. |
