Conservation of energy has been tested repeatedly to the nth time and hasn't
failed yet. Basically in terms of energy input =output +losses so output is
always less than input. (efficiency less than 100% as losses always do
exist).
In other words, there is no free lunch!

Perpetual motion requires output in excess of input -hence the alternate
name "overunity" -better than 100% efficiency. It ain't going to happen.
