The efficiency of the alternator has a huge impact on the amount of HHO that can be produced, I would of thought that was obvious.
Efficiency in this case is not size related. The uprated alternators used on ambulances are about the same size as the standard alternator, wouldn't fit if they weren't, but its able to produce far more power than the standard one. It produces more than enough to run the engine and all the equipment in the back of the ambulance, produces 6 times more power than standard if I remember correctly.
Actually higher output doesn't mean more efficient, it means more turns of copper wire, which means more dead weight to carry and more rotational weight to turn. a car alternator like on most fiats is about 65/70amps all the ambulances round here are mercedes sprinters a low end standard sprinter van has a 90amp alternator, an ambulance probably uses the top end 220amp alternator in truth this is only needed to keep the huge leisure batteries topped up to power the tail lift and rear cabin lights, and charge a couple of pieces of equipment the heating is done off a fuel burning heater and and engine block heater powered off the mains. There really isn't a lot else in there, our critical care paramedics car carries a fluid warming cabinet thats the only additional thing.
yet a HHO generator only needs a few amps maybe 3-4amps for the big fuel cell you pictured. (in perspective turning your lights on draws more current) you would need a lot of them in a car to warrant a £500 200+amp alternator?
If you really think large oil and car companies would allow a device to flood the world markets that effectively turned their multi-billion pound industries into expensive scrap you need to wake up and smell the coffee.
Oil companies have already had to stand by and watch the influx of hybrid cars, and all electric cars. along with biodiesel and other forms of alternative energy which does little to benefit them.
additionally car companies have spent millions on developing hydrogen powered cars and the best they've come up with use hydrogen powered cells to produce electricity, and power electric motors, to get anything close to viable as an alternative to fossil fuel. these are still stupidly heavy and inefficient. and more importantly horrifically expensive.
you don't believe that the millions that people like BMW, Audi, Fiat, Ford, Mercedes, Volvo etc; spend every year on alternative fuels research and development, this technology hasn't been tested? with properly developed equipment.
there is no denying an engine can be run on hydrogen, the problems come with getting it to run properly and not damage an engine. while still carrying enough to have a decent range. You will never get something for nothing, so you will never see an improvement in fuel economy by taking power away from the driven wheels of a car.
