My name is Dr. Sheldon Cooper. I am a Caltech theoretical physicist. I would describe myself as calculating and cynical, believing that Leonard (my roommate & colleague) is only setting himself up for disappointment as he continues to have a crush on our neighbor, Penny. I often represent the voice of reason amongst my friends, as I do not hesitate to point out the facts.

  • How to Convert Water Into Fuel by Building a DIY Oxyhydrogen Generator

    Modern gasoline cars analyse their intake several hundred times per sec. and adjust the air/fuel ratio accordingly. That's why they can run on regular w. 91ROZ, E85 w. 104ROZ or LPG w. up to 130ROZ, without running to lean or too fat :) Injected into a diesel engine along w. the diesel oil, the oxyhydrogen optimises combustion, by lowering the combustion temperature.

    I built this 10+ years ago. It works. Only hiccup (in your setting as well as in mine back then): more energy is put in then comes out (silly laws of thermodynamics - physics is a heartless b***h :). The key could be: a pulse generator, like Stanley Meyer did in his water fuel cell, who allegedly ran a car w. it :)
