Damn bro, this story was awesome! I always say everyone smokes weed at one time in their life or another lol.. I have heard a lot stories about people who have made engines that run on water. I totally believe it as the hydrogen (in H2o) is an extremely powerful element, I mean look at the hydrogen bomb and lets not forget H2o even powers us humans, even more so than food!
Unfornately most people who try to come out with this information usually end up dead rather quickly. Oil companies (and some countries governments) can't compete with an engine that runs on water and doesn't produce pollution. I hope your buddy can safely share this information with the world someday.. It could change the world as we know it! Can't wait to hear the next chapter of your adventure.
