HHO production costs versus gasoline costs

[Low-Q]

Some figures dropped in my mind. I am thinking of the cost of producing HHO in a quote which can power your car for 6 hours. A car that travels at 80km/h will spend approx 20HP to maintain velocity. That is about 15kW. 15kW electricity in one hour costs approx $2.50 (In Norway - all inclusive). That is 80km drive. A gasoline tank in a family car lasts for about 6 hours at that speed. That is a total energy consume of 90kW/h. In Norway, 60 l gasoline costs about $160. 90kW/h costs about $15.


Let's say the HHO production is 50% efficient. That means it costs about $30 in order to drive the same distance as with gasoline at the cost of $160.


However, it takes 130 amps from a 230V grid to charge the car in 6 hours - to fill the "tank"....or 11kA in 5 minutes if you are in a hurry.


Just some figures if you find it useful.

Well the problem is storing the hydrogen safely. Most people are using their Alternator on their car to produce hydrogen, not their electricity from their house or garage. 

One way to use the alternator to produce hydrogen freely, is to use the alternator as a regenerative braking system. When you are slowing down to stop signs, slow the car down with the alternator instead of your brake pads, and store the hydrogen somewhere temporarily. This is probably an impractical setup and too costly or complex  to build.

It is interesting to note that on average, the efficiency of vehicle alternators is 30% or less. It is possible to make permanent magnet alternators with an efficiency of 90% or more, at a cost.

I thought the permanent magnet alternators were not very efficient because you can't turn off the magnet when you do not need the alternator. With no magnets, you can turn off the electromagnetic field whenever you want...

Why not make a battery hybrid?  Put a couple extra 12 volt batteries in the car to run the HHO cell to achieve the same distance as the tank of gas.  Since you only need to charge a handful of batteries it won't take too long.
