Wow! That is exciting stuff, and in your backyard too. Give him a call and see if we can borrow a few 4S 5000mAh packs for beta testing. If the discharge rate is anything like the charge rate, it will make for some interesting SAW competition.
I have create an oil tanker : there is an oil pick up in the strut.
The oil goes back to the front of the tube, just with the pressure.
I have made some oil pressure measurement,by measuring how high the oil goes in a pipe when getting out of the strut : 1,4 meter, eg a pressure of 0,13 bars, e.g. 15 PSI
