Chain Reaction1996 - 1996

Keanu Reeves plays Eddie Kasalivich, a brilliant young machinist working with a team at the University of Chicago to create free energy from bubble fusion.
They have obviously been trying for quite some time, and, when Eddie comes in to work that morning with them, they try, and fail, once more. Back at his house, Eddie uses a Lathe to machine a metal part. He has his regulator and some sort of a mini reactor set up on a desk. When the lathe makes a certain high-pitched sound, the water in the reactor reacts. Eddie records it with his computer, and plays it back, he makes a completely stable hydrogen reaction.

He calls the project leader, telling him the news. The scientists hold a party at the lab, with the reactor churning away, with everyone dancing and drinking champagne, with cameras and balloons filled with spare hydrogen.
