I assumed I guess incorrectly they were storing the energy from the blocks in batteries otherwise once cables stop everyone loses the added power or power offset. Doing this without some type of capacitive storage suggests in my mind a Rube Goldberg machine of sorts. I guess I will wait to see what this complex beast looks like.
