P=NP, what do you do?
whatusername: I wondered along these lines recently.  A relative is getting caught up in the "water-car", "Brown's Gas", Hydrogen internet scam..  Where you convert water to 2H2 + O2 and burn that to power the car, house, etc for "free".What would you do if it actually worked?  How would you convince people?  Where would you share it?
