I'm pretty much broke all the time so I am always looking for cheaper ways to do/own things. Flash suppressor?(no..I promised my wife no built in weapons on the hovercraft) Adding cold air increases HP (Ram Air) Usually it seems HP and efficiency don't go together. Alot of cars are de-tuned to make them more efficient.
Redpepe..Dr.B mentioned the use of drano and water to release hydrogen. That will be a cheap experiment. I know I'll play around with it. Of course I was going to do a distillation of water experiment anyway. Infact I tried,but I have an electronic battery charger and it won't run if it isn't hooked to a battery.
Dr.B...Population doubles about every 80 years. At some point there will be nothing left. Changes really need to be made on an indvidual basis. What works for you may not work for me. My wifes mini-van can take e-85 so..I started looking at brewing again.
