Does anyone know what an "HHO Fuel Cell" is or what it does?

Saw this on Craigslist, and it has my curiosity going like never before:

In case the ad is no longer valid:
hho gas fuel cell all stainless steel parts built to last easy way to save some money on gas if you have any questions feel free to call 920-948-4583



So it looks as though this guy who is selling them took a picture of the product on his 1970's kitchen floor - lol 

Is this thing like the "turbonator" ?

Or is it real?

Anyone know about these?

Should we all pitch in and check it out?

Please discuss ........

Looks like a household water filter to me.

It does kinda look like that, but how would that improve the performance of your car?

That can not be all it is, can it?
