Take a look back at the H2 threads here.
We had a lot of fun back in the day




Thermal build-up in the electrolyzer is a volumetric equation
the problem is resultant from too much current over time per volume.
Solutions include decreasing the current and boosting the voltage
Or increasing the volume of the reservoir.
Other implementations have included heat-sink layers around the containers.
(with varying levels of success)

Another source of electrolyzer thermal-build up is internal pressure.
This can become significant in large tanks with high production rates.
Multiple smaller tanks can be used instead.

Pulse generation can also limit heat build-up,
and you are correct in your thinking, this does inhibit gas production.
Simply enlarge the electrolysis system to provide the gas needed for your engine.
I have seen as many as 8 electrolysis chambers experimented with.
(And yes it takes up a lot of space)


I don't mind criticism. It helps push technological advancements
But if you are just here to say "Nay"
At least use your noggin a little bit.


It is a Carnot cycle. Now set your presumptuous educational hoopla aside
and look at the box the system is contained in.
If we are recycling thermal energy from the cold side back into the hot side
We have now exceeded the 50% efficiency constraint.


Let it sink in before you pick your book back up....

Realize that the radiator of an ICE is a secondary heat engine
Built into the system


It doesn't "do" anything, but that's just lack of design
it waste heat just the same.
If we used that heat, it's less wasted energy.
We can furthermore place peltier/seebeck devices around the
engine block and exhaust systems.


Now the math gets interesting, from a thermodynamic perspective.
Compared to everything else the car is made of,
Aluminum and graphite are abundant and cheap.
modern radiators are already made with a heavy aluminum content,
the design change is minuscule, a backyard mechanic can do it in his head.
Though an automotive corporation would spend millions in R&D and testing.


TEGs have been in use on tractor-trailers for 50 yrs.
Some of the nice ones can recover as much as 20% of the engine's power
With a small ring placed around the exhaust pipe.
These are used to power 1-5kW electrical systems in the cab.
They are expensive, but pay for themselves in gas over time, by not needed to
generate that much power.

If the radiator were a pipe
imagine a continuous outer sheath of peltier junctions, and heat sink material
to transfer heat to the wind on the outside.
The shape and design of the radiator doesn't change.
We simply add the junction layer between the heat source and sink


You can use the pencil you wrote it with......


Ultimately capitalism will take over and they will be made with semiconductor ceramics
and the "generator radiator" will be expensive....
This will be limited somewhere at which the ability to generate electricity and
the ability to dissipate heat balance out with the engine specs.


But a cheap reliable product can be made with inexpensive materials.
I experimented with every conductor I was able to obtain
and the best TEGs for the $ or ease of gathering supplies
are made of Aluminum and Graphite.
Soda cans and pencils or whatever


A greater number of smaller junctions can make electricity faster
A smaller number of larger junctions can dissipate heat faster
It is an inversely proportionate relationship based on the thermal conductivity of
the materials.

TEG insulation can be placed inside the interior paneling
And your car be be a solar-thermal Generator while it is parked.
(and not be quite so hot when you get back in it)


Similarly, when it's cold the insulation would generate electricity from your heater
instead of just radiating your warmth to the outside in waste.


We know what happens in a closed system. We don't need to look there.


Let's think about open systems, systems inside of systems, or interlinked to share and
communicate energy. What we do with the energy in all forms of conversion should be
carefully considered with everything we are doing.
Wether we do anything with it or not, acknowledging that it's there, keeping that awareness
opens the door to do something with it later.


We think of the radiator as being a device to solve a problem.
What's the problem?
There's too much heat (energy).
That's the problem?
Yep. Radiator coils stuff down.....


Listen to the same Toyota engineer try to have a serious conversation about the efficiency
of his engine......


Supply and demand runs our economy.
If we started getting serious about how we use that energy, we will find that
we don't have a shortage at all
the commodity providers won't know what to do with all that energy they can't sell

I was researching heat exchangers (geet ect) and drifted to tractors which led me to cars and holley sold exchangers back in the 1920s. maybe useful info, check the diagrams against the real thing , which are also on ebay
maybe relative to radiator experiments
