For years, acetylene gas was used as lamps by combining water (H2O) and calcium carbide (CAC2). Has anyone, in history, ever devised a way to use this gas to power an engine, or as a catalyst for some other fuel? I am no chemist, so forgive me for being chemically naive. And wood there be sufficient fuel stock to make a difference if someone could make this work? Obviously there should be enough water. Any ideas? Forgive me if I am way off base.
