HHO / hydrogen generator (water for gas) from Westcoast Exterminators!

New from Westcoast Exterminators! This simple gadget increases my 95 Ford Exporer's MPG from 15 to just over 20 MPG, for an extra 100 free miles out of every tank of gas. Cost about to build. MAKE SURE ALL POWER IS DISCONECTED WHEN OPENING UNIT! KEEP ALL SPARKS AND FLAMES AWAY FROM WORKING UNIT.
