Liquid Hydrogen is currently the fuel choice used for space exploration by
Combined with an oxidizer such as liquid oxygen, liquid hydrogen yields the highest specific impulse, or efficiency in relation to the amount of propellant consumed of any known rocket propellant, according to NASA.
Liquid oxygen and liquid hydrogen are both cryogenic, meaning that these hydrogen high pressure reservoir must be carefully insulated from all sources of heat, such as engine heat transfer, exhaust heat and air friction at high
road speeds.
Radiant heat from warm climates is another massive challenge, especially during the summer months, after being parked outside in the sun for a day.
When liquid hydrogen absorbs heat, it expands rapidly so venting is necessary to prevent the tank from exploding. Metals exposed to this extreme cold temperate needed for liquid hydrogen become brittle.
Liquid hydrogen can leak through minute pores in welded seams.
Solving all these problems requires an enormous amount of technical

expertise, the highest production quality of storage tanks and prohibitive production expenses.
All the challenges mentioned till now are only from the vehicle’s manufacturer’s point of view. The same high risk and investment challenges are found on building and maintaining liquid hydrogen fuel stations. Each hydrogen fuel station infrastructure will cost large capital investment and also poses high risks to the public. Having enough stations to cover all areas of the country, like our fuel stations will eventually pose very high hazard risks and massive capital investments. No political leader will likely ever let these stations go through approval across the entire country with these current problems.
Maybe if enough technological advancement together with cheaper manufacture, storage and other lower risk solutions are found, liquid hydrogen will probably find its place in our everyday vehicles.
The Liquid Hydrogen Solution
The current easy and inexpensive solution is to abandon hydrogen liquid fuel and use something else instead. There is an easy solution available to us which gives similar results with much less expenses, and virtually no hazard risks in fuel storage. This is “Hydrogen-on-Demand” through the water electrolysis process. The electrolyte is our secondary “inert fuel” storage.
The only disadvantage is that we have a hybrid performance engine which still requires fossil fuel (gasoline or diesel) to run, as opposed to engines running solely on liquid hydrogen.
Many intelligent observers ask a very valid question:
"If Hydrogen-on-Demand is so good, why don't the manufacturers put them in all their cars?”

This question creates huge debates and controversial conversations from many different angles.
A certainly known fact is that fossil fuel has hefty profits for the oil companies and the even the government recoups a lot of money from the fuel tax imposed on the citizens — “fuel consumers.”
Anyone with enough intelligence will certainly become aware that sure enough — money is the main cause of exploiting the potential of using Hydrogen-on-Demand in brand new vehicles.
From the consumer’s practical view point is that HHO generator systems do require a little amount of “extra” maintenance, with periodic draining, flushing out and refilling with the correct solution of electrolyte.
This may be more inconvenient for certain customers who are accustomed to only filling their vehicle with fuel at the pump station and taking their vehicle for periodic preventive maintenance, like oil changes and engine service.
Overcoming Warranty Issues
Warranty claims on new vehicles which had an additional professional installation of an HHO generator system should NOT affect the warranty as long as the engine is not altered in any way internally.
There is a special Act called the Moss/Magnusson Act that prevents them from not honoring a warranty because of aftermarket parts added on, unless they can prove it caused the damage.
This Act was passed through so that any customer who added approved aftermarket products to their cars like headers, high flow catalytic converters high performance mufflers and high flow air filters would not have the whole warranty discarded because they modified it for better performance.

As long as it isn't the cause for the damage, they HAVE to honor the warranty.
Disclaimer:
Just because THEY SHOULD honor the warranty it DOES NOT mean they
certainly will.
If unsure, check with your dealer first.
My Personal View:
Both the wet and dry HHO generators are only additional extras.
They do not interfere with the engine internals and can be easily removed without any problem. The engine would run back to its prior installation, probably even smoother because of less carbon caused by the burning of fossil fuel. These systems “steam clean” the engine internals.
My suggestion:- Build or buy a kit, install it, save gas, while cleaning your footprint on the environment.
If your car is still under warranty (most expire after 3 years anyway), and you are concerned about the dealer's concept of using an environmentally safe Hybrid Fuel like hydrogen, then just take 10 minutes and remove it before servicing. You don't disconnect anything from the original engine configuration, or in any way harm the existing engine with an HHO generator, meaning it will just revert back to the same settings and mileage you had before you put one in.
Once the service or, in the unfortunate event of a warranty claim on the vehicle, reinstall the system again. “That is my take and view on the subject.”
