Maybe he should explain why this car wont be a success.

Time will tell if its a success or not.
That guy is visited by TV anchor and witnessed by many people, why wont it work.
 
vcheung .. go back to your US special service , detention room

Now show me the kit .. and lets talk money
 
Maybe he should explain why this car wont be a success.

Simply put, the problem with the claimed technological breakthrough is this:

Due to the stability of the oxygen-hydrogen bond, it takes more energy to split water by electrolysis than can be recovered by combusting the hydrogen so produced. Thus, the car cannot work simply on the energy provided by the system. Much more energy must be needed to recharge the battery, hence the overall system is non-viable.

(There is research going on to use fuel cell technology coupled with methane and other hydrocarbon sources by splitting the carbon-hydrogen bond that may improve efficiency over what can be achieved with internal combustion engines.)
 
Here's the deal, people: There ain't no such thing as a free lunch.

There is energy in water. Chemically, it's locked up in the atomic bonds between the hydrogen and oxygen atoms. When the hydrogen and oxygen combine, whether it's in a fuel cell, internal combustion engine running on hydrogen, or a jury-rigged pickup truck with an electrolysis cell in the bed, there's energy left over in the form of heat or electrons. That's converted to mechanical energy by the pistons and crankshaft or electrical motors to move the vehicle.

Problem: It takes exactly the same amount of energy to pry those hydrogen and oxygen atoms apart inside the electrolysis cell as you get back when they recombine inside the fuel cell. The laws of thermodynamics haven't changed, in spite of any hype you read on some blog or news aggregator. Subtract the losses to heat in the engine and alternator and electrolysis cell, and you're losing energy, not gaining it--period.
