More often than not if you can read the words free energy without having to scroll it's pointless to scroll. I did anyways because I was thinking at first they were telling people how to mix water and gasoline in the tank and just had to try and read on.
Most gas has a bit of water in it anyways. Rainwater drains right in, or in worse cases, crooked owners squirt some water down the hole to make a quick buck. At anyrate, as long as it's pure water (distilled) it will actually do a bit of steam cleaning! and cool the combustion chamber a bit (usually a bad thing as far as F/E goes) as it's pretty inert through the combustion cycle, it does expand VERY quickly when heated, so I say if you can get an oil and a water to mix (water + gas) go for it! Or heck, I might first haha.
Looking over that site, it's another HHO system but...
The biggest problem with water in gas is that it doesn't mix with it, sinks to the bottom of the tank, freezes in the lines in cold weather and of course, if you pick up straight water in the line, it won't burn... If there was a way to keep water and gas mixed, it would be a pretty good thing to try. I had heard of some guy in the UK doing that. Think he used an emulsifier.
It's said that a third of the energy in gasoline goes into the engine in heat and gets dumped by the cooling system and another third goes out the exhaust pipe. If one could introduce enough water to suck up all that heat by expanding into steam in the combustion chamber before it gets wasted, then you'd have a motor that was much more efficient. Find an efficient way to do this and your 30mpg car gets 90mpg with the same power. (You'd be more likely to just double mpg though)
By the way, using straight alcohol as a fuel, no gasoline at all, one can use up to 15% water in that... heard of folks running old VW beetles on that. I think the problem with greater concentrations is that it won't burn violently enough. We could expect a similar problem with gasoline at a certain point. However, increasing compression ratio a lot could get more tolerance for water. Conversely it might be possible to mix more water with lower octane fuel.
Since getting it to stay in the fuel is a problem the logical thing is to introduce it seperately, water injection... this has mostly been pursued for more power, not less gas. Just misting down the intake has a limitation, in that all that one can do is displace air in the charge, ECUs might then see a "rich" condition and cut back the fuel a bit, but you're limited by the flexibility of the fuelling table. Hence low water useage amounts are typically recommended around 1/8 of the fuel. This is enough for chamber cooling for high power levels, as a detonation preventer, however that's not exactly what an mpger has in mind, so there's probably some more work possible on that.
I have an idea in mind for more effective water induction, however, I'm going to have to make some WAGs (Wild A$s Guesses) about induction flow in the vehicles I've got to play with, to try and make it work. Ideally, I would do a thorough analysis of flow dynamics and arrange things perfectly so it had the best chance of working, but I don't have that luxury available at the moment. It might in fact be impossible to do on Marvin, but Wile-E might be more amenable to it. There's a small number of motors out there that just might work extremely well for what I have in mind. While useful as a proof of concept, it's going to be a little unfortunate that not many vehicles will be at all suitable, and the ones that are will need careful modification, only a relative few might benefit without having head-work. Fortunately the head-work involved should have benefits without the water, so I shouldn't be screwing up Wile-E's head for nothing. While thinking about this, I got better insight into improving normal induction.
The good point about it though is that it might work in addition to other fuelling improvements, i.e. HHO, ozone, fuel cracking, gas additives, should still have further benefits.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
