Because of our notoriety in the engine efficiency arena, we have had many calls and e-mails about HHO/HOD units that don’t work.

Reports we’ve gotten is that invariably, they get hot, melt, break, or get very limited results.

Of the THOUSANDS of units that everyone and their brother are building, have built, ebooks, manuals, and kits, by and large are a miserable failure.

The concept of mixing Hydrogen gas with fuel is a proven concept backed by studies from the U.S. government.

The trick is to get a unit that will not over heat, will not consume too much current, will make ENOUGH HHO to make a significant difference, and will last for more than just a few weeks that is Actually working ON a vehicle, not just on a test bench.

HOD.

Uli has done extensive testing on HHO/HOD units and looks to have overcome most if not all of the shortcomings of the typical devices either from manuals or kits on the Internet.

Mileage increases on a 3.0 L diesel down in Australia was in the 27% - 37% range. None have been validated on large displacement engines here in the U.S. yet, but we are getting ready to validate a dual canister setup on a 6.6L Duramax diesel we are putting into an H2 Hummer.

I’ve written an article on HHO/HOD units, if you know of a place I can get the article published, I’d welcome the help.

I bought one and I can tell you that it will not work on ANY vehicle that I have ever seen.
