Serial Hybrid
not that i know anything about electricity but
-you may needs an array of increasingly smaller capacitors to keep from sending a surge of amps to your motor as the ultracap can discharge its entire load in a few seconds
-think about replacing some of the very expensive ultracaps with a
zinc-air battery, its light, cheap and provides a steady source of power.
-if one of those ultracaps gets shorted, say in an accident, i wonder how big a mushroom cloud it makes?
were you thinking something like a
t-Rex or a
stallion?
