I like the BS Engine listed there. The name really sums it all up pretty well

<YT-AWAY> here`s one, how about capturing the energy from a falling weight and using that to lift soil from out a hole, as long as the weight was more massive per volume that the soil removed it would keep falling forever

 

It would be quite possible. You'd need to make it large enough that you could pass rocks through the center of it without having to break them apart. It would have to bury itself as it goes, though, and would need a very efficient "drill". In any case, it would eventually have to stop, due to failure when reaching magma, rock, solid iron core, or the center of the earth (no more gravity). Additionally, I doubt enough energy could be extracted compared to that required to produce it, nor that a drill of sufficient efficiency could be made.

 

Clever idea though.
