Is it really safe for me to install an HHO kit in my car?

I found a site today about HHO kits that I could use to increase my gas mileage, which would be awesome as I've been planning to do a cross-country road trip for some time now. I don't know a whole lot about cars, but I know enough to be wary of putting foreign materials into my engine. The site claims that no alternations are made to my engine and the product can be removed and re-installed in a matter of minutes, and it also says that the steam produced would actually clean my engine. It sounds a bit too good to be true.

So, is this really safe? I love my car and will be paying the loan for another three years, so I certainly don't want it to develop any problems, especially since I have to drive to college every day.

    HHO kits improve your gas mileage by relocating the O2 sensor, which produces a leaner fuel mix. This can lead to preignition ("pinging") which can damage your engine and can cause you to fail emissions testing.

    HHO is pushed by fools who don't understand the science of what they're selling, many of whom think it works. The pseudoscience is part of the marketing: we've all heard of hydrogen, we all have heard it can burn in engines, and we all know we can generate hydrogen with electricity. We all know our cars produce electricity. So it sounds like it ought to work.

    The trouble is, it takes more electricity to make hydrogen than people realize, and it takes more gasoline to make that electricity. If you could generate electricity from your alternator at 90% efficiency (theoretically possible), make hydrogen at 90% efficiency (theoretically possible), burn it in your car engine at 20% efficiency (theoretically possible), you end up making 16% as much energy as it took to make that electricity in the first place.

    To go from water, to another form, and back to water, you don't gain any energy. Look up perpetual motion machine. Don't waste your money or time on this stuff.
