[Land-speed] Hydraulic Hybrids

[Elon]

Ed thanks for the good info. Am I to assume that piston friction does not
increase with rpm?

Neil I remember that experiment but I think it was done with Kevlar. I don't
think carbon filament was invented at that time. I remember it as "proof of
concept only" and since it was successful there was no need to continue.
