Viewers have been questioning the output whether or not its really HHO gas. So to dispell their skepticism here is a video to demonstrate the flammability of the HHO output from a MagDrive Mini-Gen. You will notice, as fast as I can click the lighter there is HHO ready to be ignited. This is under about 2 psi, imagine 10 or more inches of vacumn drawing the HHO out. It would be a steady stream of HHO instead of just successive bubbles as in the dye test water. www.fuelfromh2o.com
