First Rule of Thermodynamics: There ain't no free lunch. ( Except the energy gain obtained by drafting behind an eighteen-wheeler.)
“Riding his larger John Deere tractor on a breezy day was a good recipe for a face full of oily diesel(sic) xhaust. After installing an HHO system, the black smoke is gone and the engine runs cooler.”
Does this tell you anything? Black exhaust means too little air for the amount of fuel. Install something that allows more air intake and air/fuel ratio is closer to optimal. No more black exhaust, better mileage.
Fraud? Hmmmm

It uses vacuum from your intake to suck water vapor into your engine. I have not tried it.
A proper water injection system can increase engine performance while absorbing a lot of excess heat. however this system seems to inject very little vapor and even less when the throttle is opened.
What tire pressue do you need?
There isn’t a problem of incomplete burning of fuel in the engines now. And speeding up the burning process will cause pinging, premature ignition and engine damage.
Nitro greatly increases fuel consumption to provide more power.

The engine works by expanding gas during combustion pushes the piston. If you cool the engine, don't you lessen the expansion of gases and have less force on the piston?
Now if you cool the incoming air and/or fuel, you increase the expansion that takes place as it enters the cylinder at a more dense state.
0.4 l/min of hydrogen gave a 50% increase in mileage? BWAHAHAHAHA! No freaking way. Do you realize how many liters of air are drawn through even a small engine at idle? Try about 1600 liters per minute and easily three times as much at highway speeds. So, adding 0.25 cc of hydrogen per engine cycle is going to boost my mileage by 50%? BWAHAHAHA!
P.S. Feel free to do it yourself and prove me wrong. I’ll not waste my time, energy ,and money.
Popular Mechanics already did.

It actually works, but is a lot more complex than this article lets on. If you have a car computer the higher oxygen content throws the Oxygen sensor off and it compensates by pumping in more fuel. The end result is no real change in fuel mileage. There is a circuit board that shifts the bias on the oxygen sensor back to normal that allows the car to inject less fuel to make up for the greater amount being burned by the HHO.
The result actually does lower emissions.
A second problem is that a HHO cell will draw more current when hot than when cold, so you need to drive it with a current limiter. A Pulse Width Modulator switching power supply can solve that problem for you.
Both circuits are available on the Net and is free at Alt-Nrg.org
All this by the way is why small emission control free lawn tractors do so well on HHO and newer model cars do not.
However the idea of running a vehicle on pure HHO is bogus, you loose energy converting the water to HHO and loose more converting it back for a net loss of energy. Not to mention that the high speed pulse of energy is not well suited to transferring torque to slow moving pistons.
HHO is only useful as a primer charge to a fossil fuel explosion, not as a source of propulsion itself.
What do you think is making your catalytic converter get hotter than the exhaust intake and why do they have to inject air into it for it to process the pollution.
Hydrocarbon pollution that is solved by the catalytic converter is simply improperly burned gasoline being re burned on a platinum catalyst with oxygen. A standard gas engine is 20-30% efficient. Which may sound bad but is actually quite good. If HHO can raise that you would see an increase in mileage, however most of the losses are heat and mechanical.
Since the oxygen produce is completely matched to the hydrogen produced, there is only extra oxygen in the exhaust if the hydrogen does not completely combust, or if a higher percentage of gasoline does not combust.
How is the exhaust getting a higher oxygen content?
No breaking of any laws of thermodynamics required for modest gains in efficiency that could be useful. Will it solve our energy problems? No, but it might be better than pumping up your tires.
Spintronics is real. But maybe the guy was otherwise like Bruce Ivins.
FRAUD.
Interesting. I guess it is part of the conspiracy that the auto makers pressurize the cooling system inorder to raise the engine temperature and increase efficiency ...
Modern cars are over 95% efficient in completely burning gasoline. The problem is that the burning of the fuel produces much more heat than is good for the engine and heat represents energy. Most of the heat goes out the tailpipe and the rest is dissipated by the radiator.
Here is the math why these devices WILL NOT WORK.
1. Assume a small four cylinder gasoline engine with a 1600 cc displacement. That's 1.6 liters of air it takes into it every cycle of the engine.
2. If it is idling at 1000 rpm, then it is taking in 800 liters of air EVERY MINUTE.
3. One of the links above claims that his device produces 0.4 liters of H2 + O2 per minute and he gets a 50% increase in mileage.
3. 0.4/800 = 0.5cc PER ENGINE CYCLE and 0.125 cc per cylinder, about as much as the end of a pencil eraser.
Do you REALLY expect me to believe that injecting 0.125 cc of H2 + O2 in a 400 cc cylinder will do anything? Come on. Popular Mechanics built one of the devices and proved that it did absolutely NOTHING.
