Increasing A Car's MPG....

There's great documentary that's called something like "Who killed The Electric Car" and describes how in the 70's or 80's California had a number of electric cars that ran on batteries. Apparently they were very efficient as well as popular, but the powers that be made sure that these perfectly good cars were rounded up and crushed. The "powers that be" included the oil industry, car industry...(these ultimately being the puppets of the banks) and of course the government (REAL puppets of the bankers).....Amongst other things this documentary described how an oil company had bought up the patents for the electric car's improved battery capacity. So there seems to me at least, forces involved in making motoring more expensive than need be.

Speaking to my fellow enthusiast Tom Hackett about this sort of thing, Tom told me an interesting story. Just after World War 2, his dad worked at Austin looking after engine, gear box problems etc that other engineers couldn't sort out. One of of the projects he was involved with was a means of injecting water vapour through the fuel system. The idea was that after the engine had warmed up the petrol/air mix was unnecessarily rich so a DILUTED PETROL/AIR mix might work just as efficiently. So along with petrol vapour and air there would be an injection of water vapour. Tom said that his dad said there was a doubling of the fuel efficiency for this system...but why haven't we heard any more ? Well, why do I find that surprising ! (Incidentally, many people report that their vehicle runs better in the ran - because of the increase of water vapour through the carburettor ? )

After discussing this Tom subsequently sent me a link for this:

I have just started experimenting putting acetone in my car after find this article on the net :

..it's supposed to increase the vapourisation of petrol and so make it more efficient.
