Hi Steve, welcome to Wikipedia.

I reverted your Tesla addition to free-piston engine, because it's a genuine Tesla invention, but I think it needs to be described under "reciprocating generator", "free-piston geenrator" or somesuch, not free-piston engine. It might even be possible to put it within free-piston, but it would need to go in a separate section.

The issue is that Tesla's invention was a motor, but not an engine. It takes pressurised gas (most likely steam) and uses that to work a piston. It then invented the new idea (which is why it's relevant to the free-piston engine) that useful work could be extracted from an engine without a mechanical connection. However what it didn't do was the work of an engine: converting a chemical fuel into mechanical work. A free-piston engine doesn't have an external power supply (other than fuel), it produces this power from within it. Andy Dingley (talk) 13:00, 11 March 2011 (UTC)
