Description

A small motor is powered in between two 350 Farad 2.7 Volt Maxwell Ultracapacitors hooked up in parallel.

The first supercapacitor's current runs the motor as it charges the second supercapacitor at the same time.

The main point I want to get across here is that it is said that half of the energy is lost during the transfer of energy, but how can that be?

They say it's from resistive losses, but then that's like saying if I had a gallon of water and poured half of the water into another empty gallon that half my water would simply disappear! When in reality I still have my full gallon left except it's just been divided in half in two different places.

Really? There's that much resistance in a .1 Ohm of connecting wire and in the capacitor? There's that much heat? Does this make sense to you?

They show the MATH for where this this loss goes but I just don't buy it, at least all of it, it only makes sense when you try to pulse a coil from one capacitor to charge another capacitor of equal value, then one is never really able to charge it to the same voltage level that it started out with, then that would be 100% energy transfer.
