You know, if you really think deeply about all these "wonder fuel savers"
If they were really so great, the would be installed on new vehicles at the factory, and even mandatory by law. Geez, I hope my friend did not fall for this yet.
Preach on, brother! Saw one such device advertised at a major truck stop chain when it first came out. I did a quick calculation based on some of the "bullet point" claims - if the were all true, it would be a "bolt-on" improvement of a full mile per gallon (check my vehicle list as to why this is VERY significant). Same device is now (about 6 years later) being thrown in free with an oil change at that same chain.
The trucking industry lives and dies by a fraction of a mile per gallon. If I invented a device that produced a "bolt-on" 1 MPG improvement, I wouldn't be manufacturing them and trying to sell them through truck stops - I'd segment the market, and auction off exclusive rights in each market segment (e.g. "North America on-road"). If one of the major truck manufacturers could offer a clear 1 MPG advantage over their competitors, they could boost the price of their trucks by $50,000 per unit, and it would be money well spent, so even that one segment of the market would be worth a fortune. Instead of needing to keep building and marketing the devices, I'd be sitting on the beach with a cold beer in one hand and a hot blonde in the other.
With respect to hydrogen, they fail to understand there is already far more hydrogen contained in the hydrocarbon primary fuels powering their contraptions. Well, save Stan Meyer's mythical dune buggy, stolen by "sharks" after Stan was "poisoned" by Arab oil Sheiks, the military, Big Oil...
I'd put the military in a different category - they'd slap a "top secret" label on it to keep OTHERS from finding out, but they'd actually USE it. Can you imagine how much it would ease logistics problems if they could significantly improve the fuel economy of the M1A1 tank, the Bradley IFV, the Humvee, etc?
I occasionally have access to jet A fuel, does anyone have a formula to add a lubricant to the fuel so it can be safely used in the turbo jetta?
Do you have an oil furnace at home? No need to add a lubricant, and since a furnace doesn't operate on public highways it would be a LEGAL use for fuel that hasn't had road taxes paid. Bear in mind that there are 2 "families" of jet fuel - the kerosene-based (includes Jet A), and the naptha-based (includes Jet B). In a turbine engine (and probably in an oil-burning furnace) they'll both work. I wouldn't want to get Jet B anywhere NEAR a diesel engine. Also, does your source of "sump fuel" work on piston aircraft as well? If so, you could have contamination with 100LL avgas, and I'm sure you've seen threads about what happens when a TDI gets fed gasoline-contaminated fuel.
submarines can provide oxygen enough for a large crew and remember that there is twice as much hydrogen when split from water...subs expel all this back into the ocean
ratheon builds the electrolysis units for subs and knowing someone who works there i have been told they have fueled a hummer with one of the units providing the gas on demand....thats not stored or compressed...just a live reaction from water
But WHERE were they getting the electricity to power the unit they were using to fuel the hummer? AFAIK, except for a few specialized units (e.g. rescue vehicles, SEAL tow vehicles, etc), all subs in current U.S. Navy inventory get their primary power from a nuclear reactor (some may have a diesel on board as an emergency backup to get to port in the event of a reactor failure, but they'd have to run on the surface to use it). You can be damn sure that the hydrogen from the electrolysis unit is NOT being used to re-assemble the fission products back into U235.
