No need for catalytic converters anymore.
I've been building hydrogen generators for gas vehicles for years and they do work. They double gas mileage, increase the horsepower, and clean out the interior of your engine which also keeps oil cleaner longer. This technology has been around for a very very long time but these corrupt politicians have suppressed it for so long, this is nothing new. 😁
How is the hydrogen produced?
Hydrogen is produced by running a 12 volt electrical current in between stainless steel plates or tubes one side being negative the other side being positive separated.
When the plates or tubes are immersed in water they create an electrolysis which causes bubbles to go up into the unit and the gas is released are hydrogen and oxygen as water is one molecule hydrogen to molecules oxygen.
You could see several different hydrogen units that they sell on eBay just type in
"hydrogen generator"
"Come now, and let us reason together, saith the Lord" Is1:18;
So water is used up in the process? ... water is getting sort of scarce isn't it? Does it have to be fresh water?
then hydrogen is burned in the car
Where does the exhaust water come from?
So then hydrogen is produced on board?
The 'charge' mentioned in the meme then is the on board 12v battery being charged back up that produces nearly 1000 mi worth of hydrogen?
What sort of battery we talking?
EV sized lithium?
