3000 Farad Supercapacitor – any ideas?

Where’s Nikola Tesla when you need him?

Electronic Goldmine have just started to sell 3000 Farad (yes *Farad*) super capacitors for a mere $29 – I’ve been sitting here thinking that there’s got to be *something* really cool you can do with these things…

Anyone got any good ideas?

Just to give you a sense of scale, most capacitors are measured in microfarads, millionths of a farad, 3000 Farads is pretty darned big. Maxwell Boostcaps run at 2.7V which really doesn’t sound like a lot, but the massive capacitance means that they can store and deliver very large amounts of current. And as we all know it’s the current that’ll get you, not the volts. Large currents can melt steel (Mig/Tig welding) and generate large magnetic fields when passed through a suitable conductor.

How many would you need to move a garbage truck from one house to the next with great acceleration and no “revving diesel” noise?
Charge while braking. Discharge to accelerate. Use the fuel engine only for the losses. No more unwanted 5am wake up calls.
