Why don't superchargers and turbochargers break the laws of physics and HHO generators do?
I saw an article today on how HHO generators are just a scam. There are of course many scams associated with it, but I have yet to test the whole thing myself so I have yet to form a solid opinion on the whole thing. One of the biggest arguments is that based on the laws of thermodynamics, the same energy is required to split the water as is released when they recombine. This is true, but couldn't there be other benefits to the whole thing which are being ignored. If that statement was true wouldn't eco-boost engines be a scam. The turbocharger can't just create energy can it. The exhaust which spins up the turbo causes back pressure on the engine right. Then there are friction and slip as well. It seems very lossy right, but it works. It isn't a scam. The same goes for a supercharger, the same energy of the added compressed air is taken from the engines drive train. Now I understand that the compressed air causes a better burn similar to mixing KNO3 with sugar vs just burning it in plain air. But what if you mix gunpowder and sugar, why is that any different. I feel like this analogy accurately displays what is going on in both cases, and I feel like there could be an argument for the benefits of HHO. Again I have no experience in the subject yet, but it all seems reasonable. The HHO isn't being used as a fuel, it is being used as a booster which pulls more energy, more efficiently from the petrol.
