Their website isn’t entirely clear, but if I am reading it correctly, you retrofrit this unit to your vehicle and can increase the mileage by 75% – 125%. The system uses hydrogen in combination with your vehicle’s preexisting source of energy. To fill up, you simply add water and the system converts Hydrogen on the spot. They’ve built-in some failsafes in the event the system goes hay wire. The price you ask? Just a mere $3,500 for gas engine and $7,000 for diesel.
Looks like the Scorpion Hydrogen car is using this system. At a 200 MPH top speed I can’t imagine its range being massive, though. Hit the ‘leap’ to peep the Scorpion.
