Hi,
I understand what you are saying and I concur with your basic thoughts and I am not advocating this conclusively. However, if we are going to talk about efficiencies, lets talk about the basic efficiency and fuel consumption figures of an internal combustion engine. In more than 100 years since the production of the first mass produced car, the Ford T model which delivered approx. 30mpg (12.75 km/litre) and based on all the technological and engineering development in that 100 year period, the latest Ford Explorer delivers a pathetic 18mpg (7.65 kl/litre) it would appear that we have gone backward. Yes, you can say we have more power, performance, luxury etc.etc.etc the fact remains that the average motor car driven by an internal combustion engine using gasoline is extremely inefficient.
Most things that are electrically driven or consume electricity by comparison and I'm sure like all things there will be or are exceptions, are far more efficient. The conversion of water back to its gaseous state using even a standard battery, is far more efficient than the energy consumed and produced by an internal combustion engine operating on gasoline joule for joule.
If we take it a step further and add a recent technology solar panel to the system to assist in replenishing the charge in that battery, which to a degree provides us with a source of cheap readily available, energy we have a very efficient system.
It is only a matter of time before we start to see some sort of ascetic form of solar panel fitted to the motor car to assist in battery charging.
(The X19 lends it self to existing formats, with its black engine cover at the rear, than most other cars.)
If we look at your car battery for example, placed on a charger with even a trickle charge of 2 amps, it is still producing Hydrogen gas, attested to by the fact that it is strongly recommended that you charge in a well ventilated space away from naked flame or spark.
The long and the short is yes I have already virtually finished building a test unit. Yes I will be trialling it on my X19, yes I will be doing a number of checks and balances to assess its worth and no I wont believe you until I have well and truly proven it for myself.
Anything will be step in the right direction, both economically and ecologically over what we are currently subjected to by the oil barons of the world, especially as it has now been successfully driven passed $90/barrel.
