Surely some out there have read Philip Jose Farmer's River World series. Mark Twain ran his Fabulous Riverboat from an ultracapacitor. Can you imagine what would happen if you accidently shorted a ring across a fully charged ultracap of 20,000 Farads? Goodbye finger(s). Allen KA5N

It seems to me that the calculations in the original post are not quite right. 1F = 1V * 1 Coulomb. The Farad is a Coulomb per Volt or Q/V not Q * V This starting point inserts errors in the calculations that follow. For example: Thus 1F = 1V * 1 Amp Second. The unit V * Amp * sec is
