This theory does work at a very basic and simple level. Browns gas added to gasoline in smaller low pressure amounts is not that difficult to due and control BUT IT DOES require some work and some mods. These mods allow you to remove a little gas from the delivery system (injection fuel map) so the browns gas can replace what you removed. My experience is 25% up to maybe 35% is very realistic with higher percentages a bit over my head or maybe only available in very few scenarios.

Browns gas has some cool attributes like quenching the fuel charge, reducing operating temps and adding a small amount of extra power. The extra power is small and about the difference of turning your cars AC on and off.... small but noticeable. This is a very low pressure system without storage potential or difficult control systems. As a basic system there are also no explosion or real fire hazards either and an on/off toggle switch returns everything to factory specs.

Other systems or those running high percentages of hydrogen are high pressure systems much like propane. High pressure delivery is a whole different ballgame and way more than I want to mess with. Storage, generation, delivery and explosion potential are just a few hurdles to overcome with high pressure systems. You can run on 100 % Hydrogen but not with jars and rubber tubing and a few electronics and no way a 100 buck install. Plus it makes water and engines don't like water in the crankcase etc.

A low pressure home built system once you know what and where to get the items needed are about 100 bucks for just the generator but it took 5 times that to get the list and experience together. Then you need to modify your cars ECM so you can start to remove a portion of the fuel mapping. This includes 40 bucks in parts for tweaking the MAP sensor output. You also need a way to remove sense voltage from 02 sensor on final sensor as it will read 15% high and ECM will throw codes and remove timing and a lot of bad stuff, another 70 bucks. Now ya need all the install and tweaking time and a bunch of Patience. In the end you can get an easy 20 percent fuel savings and the next 5 to 10 percent is relative to your Patience and time invested.
