On: Aquarius builds an engine others only dreamed of

[miahi]

It seems to generate quite a bit of vibration, even if you couple two of them in an alternating way you just change the vibration from parallel to the pistons to perpendicular to the pistons. It's not as easy to balance as a rotary engine.

It's not for vehicles though. It's for power generation. I guess you could use it in a vehicle, but I think it's intended for stationary use.
