nadenitza: The way they handle energy from the gas is revolutionary. My claims are not false, there are patents being filed here on technology using brown gas in automobiles and heating, i can give you vids about it but they are not translated so you won't understand what is said and i dunno if i can translate em accurately enough either. Basically a professor here named Mircho Tabakov claims his generator is capable of lowering fuel consumption in automobiles by 38-40% with no tweaking to the computer electronics, witch if the car manufacturer puts his hand in it (expand on the technology in other words) that % will raise even more, he says probably more than 60%. He found a method to power the generator more efficiently, that's what took him the most time.The heat produced by the generator is ambient temperature, he said for a 400 km mileage the temperature of the generator rose only by 10 degrees so there is no loss of water by overheating the generator and vaporizing it. The fuel consumtion is something like 2,7 L per 100 km for 1.7 diesel engines, 2,8-3,1 per 100 km for 1.4 petrol engines
Hi, professional chemist here- I suggest you learn a bit of chemistry, as once you do you'll quickly see just what a load of hooey this all is. "Brown's gas" is nothing more than a mixture of hydrogen and oxygen, most typically generated by the electrolysis of water. The way energy is generated from this is by burning it, which is the exact opposite chemical process by which it's generated (2H2O -> 2H2 + O2 vs 2H2 + O2 -> 2H2O). The maximum energy you can get out of this process is exactly the energy you put into generating the original gas mixture, although in practice it's always lower due to various inefficiencies.
Furthermore, the burning of hydrogen to generate energy is a nearly identical process to the burning of hydrocarbons to generate energy, except that the energy density of hydrogen sucks ass compared to that of gasoline. Gasoline has an energy density of 34 MJ/L, while hydrogen at atmospheric pressure has an energy density of a measly 0.01 MJ/L. Even if you compress the hydrogen to extremely high pressures (near 700 atmospheres, which is not a state you want to be storing hydrogen in) you'll only increase the density up to 4.5 MJ/L. Even liquid hydrogen (if anyone is crazy enough to deal with it) only gets up to an energy density of 8.5 MJ/L (only a quarter of that of gas). Like I said, the energy density of hydrogen sucks ass. There's various bits of work that have been done on hydrogen storage to try to safely increase the energy density, but as far as I'm aware none of it has produced anything near good enough to be useful.
As for the claims of using Brown's gas to improve combustion engine efficiency, this is possible, but is simply a worse method of doing what can already be done through much better methods. One of the inefficiencies in combustion engines is incomplete combustion of fuel, where instead of completely combusting to form only water and carbon dioxide, various small, partially oxidized hydrocarbons remain. A way to combat this is to increase the oxygen partial pressure in the fuel mix, and pumping in a hydrogen/oxygen mixture does accomplish this (only by virtue of the oxygen present- the hydrogen present is just a waste of volume). However, as I mentioned there's already much better ways of doing this. Nitrous oxide is already commonly used in racing to accomplish exactly this- the nitrous oxide gas decomposes to oxygen and nitrogen, producing a nice supply of oxygen. Additionally, nitrous oxide is much safer to store than mixtures of hydrogen and oxygen (which are basically bombs waiting to go off). The increase in efficiency is also small enough to not be worth the trouble of needing to store a second (gaseous) fuel, which is why this tech isn't used in standard commercial vehicles (in racing the interest is actually in the increase of instantaneous power generation, not the increase in fuel efficiency, which is basically a rounding error compared to the various other factors affecting fuel efficiency).
