FUTURE INVENTION - RUN CAR ON WATER (HYDROGEN)
Here is a future invention that is already here. While the major car manufacturers are experimenting with cars run on hydrogen in the future - there is now readily available a process that makes hydrogen that you - or your mechanic - can use to make your car run on water.
The big boys are playing with hydrogen cells that carry 10,000 psi - how to protect these cells in an accident - and how to get the cells refueled with service stations that can create such pressurized hydrogen transfer safely.
But this safer process is here now. you can convert your existing gas-guzzler into a cost-efficient and environmentally-friendly hybrid system that runs on water.
WARNING: DON’T EVER PUT WATER INTO YOUR GAS TANK! This future invention uses a simple electrolysis - working with water and electricity - to convert the water (stored under the hood) to a usable form of hydrogen that can boost mileage to between 50 to 300 miles for each gallon of water (up to 50% better gas mileage). The cost to set your car up is pretty minimal - around $100 to $150 should do it for a step by step manual and parts.
UPDATE: I recently talked to a representative of the California Air Resources Board ("CARB") about this process. He had not heard of it, but when I explained it he was positive in thinking it should and would work. BUT - if you live in California and hook up this system - even though it provides cleaner emissions and better mileage - you would fail the required SMOG Test because you did an unauthorized modification to your vehicle.
OTHER STATES I don't know about, but California is tough on any modifications. I had the same problem back when with a 1974 VW bus. The Manufacturer's dual carburetors were awful - even after a total reconstruction. There was an after-market set of carbs built by Weber that ran cleaner, produced more power, and had better mileage - but couldn't be used because they were not passed on by the CARB.
SO - all you other states --
