An normal Lead Acid car battery produces HHO when being charged,(which normally happens while driving thx to the alternator) with the amount increasing a lot from around 70% charged and up.

I haven't done the (linked) maths yet, but as we are going for "every bit helps" here...:
Std batteries have a little vent nozzle to which a small tube is attached when fitting a battery, that normally vents under the car.
Making said tube vent into the intake is a very easy/simple mod.
Why car manufacturers DON'T make the vent that way:
If the engine backfires you would light the mixture in the vent tube, which having the perfect mixture of H and O burns/explodes instantly!
Much too fast for any type of mechanical spark arrestor (as used in cutting torches) to arrest, resulting in the car's battery blowing up!
The only effective Spark Arrestor for HHO is a bubbler.
Bubblers are simple to make:

If the HHO does catch fire the tiny explosion just POPs the lid of the bubbler.
But a bubbler makes a car high maintenance, which is why they aren't already in all cars:
You need to be sure it always has water in it.
One may want a water level monitoring device that went as far as preventing the engine from starting if there isn't water in the bubbler.
You would also need hop out to refill and re-close the lid on a bubbler if the car backfired.
(A hinged and spring loaded lid might automate this process)
It may be necessary to add a spark arrestor or one way valve anyway to minimise the POP and to stop water from being drawn into the 1st cell of the battery..?
As I said: Just a simple idea to easily get every bit of economy out of a std car.
There is no need for the std "HHO generators are a scam" type comments as we are talking about a process that happens anyway in just about every car. (fancy batteries excepted)
The bubbler (and one-way valve and level monitor) would need to be small, light and cheap to make the tiny economy improvement worthwhile.
Thoughts?
Anyone done this??
