Make the calculation. 1 ampere * second = 1 farad * volt
Let's say 3V: 100 * 3 = 300 ampere * second
Translate that to wattsecond by again multiplying by volt: 900ws
Convert that to milliwatt-hour: 900 * 1000 / 3600 = 250 mAh
Which equates to two AAA nicads.
But let's wait for the voltage these enormous caps can really take,
their physical size and weight, their self-discharge figures, and
the current they can deliver without suffering a large voltage
drop...
Best,
Steve
