Then you’re putting energy into breaking bonds which is energy you will partially (but not fully) recover by burning them. It’s impossible for this system to result in a more efficient engine.

I bought a bike online that came with some of those hex keys to assemble it the last bit. Turns out, having the hex keys for the most important bits of my bike is pretty handy and I carry them around in my bag now when I ride.
