Does that still count as reciprocating?

What I don't see is how in the hell can you cool the engine??



Sure its has 3 moving parts but its encapsulated inside of a tight ball. How about oil and lubrication?? Seems like Not well thought of an engine.. Also, look at how the air enters. It reminds me of a turbo (except it travels for so long of a path) and I don't understand why they have the intakes on the sides when you could easily put it on the other side of the exhaust.



No way it'll work.
