can i set up a capacitor bank to start up my car if the battery is dead?
a huge advantage to capacitors is low leakage (for some types) and i want to know, first of all, how much energy a starter motor needs to start the engine? one of my constraints is money (>$200) so if it works, but i can't afford the capacitors, then oh well. also, i want to know if i can make a simple circuit that would sense if the battery is dead and then switch to using the capacitors and also be able to recharge the capacitors. im also worried about the amount of leakage of capacitors with such high capacity (which might defeat the purpose of this idea), and where i could actually put the rig that would be safe from heat, and still have access to the starter motor. if this is feasable, i just might make my first instructable out of it: the invincible starting car
