The article starts dated a bit?
The efficiency of the cells has been improved, moreover, the cell that I put in link higher, allows a use with higher temperatures, which would make it possible to exploit the escape.
But I am open to any other solution to recover this energy.

the simplest thing to do for the alternator, is to order it to exit it in priority in the phase of deceleration where the engine brake is useful: therefore when the energy is mechanical and free, since if the alternator does not take it you will not have to brake
it's a bit of the hybrid of the poor: instead of having a big battery and a real electric motor, we just do what we can with a small battery
peletier module? it's going to cost a fortune to not produce much ... and watch out it's destroyed at the slightest overheating

Regarding the start during deceleration, it is possible thanks to my arduino embedded.
How to detect a deceleration?
For the overheating of the Peltier cell, the one chosen works up to 350 °.
- It already controls the ignition, engine speed, the Piezo generator, the exhaust temperature, the vehicle speed, the battery level and the immobilizer code.

it is not a question of detecting: it is rather a matter of obeying the order of the driver
a possibility: lengthening the accelerator stroke
the first run of the accelerator allows the driver to control if he wants to slow down, or not
when you lift your foot completely, or when you brake the alternator running full pot
when you press the accelerator up to a first notch that means you do not want to slow down, so the alternator is cut
when you press more it accelerates really
the alternator only works when the accelerator is fully raised unless it is not enough ... of course that on the high road when you do not often get up, and at night with the lighthouse you have to run the alternator more often
but I think that in the city, the slowdown phase or the footing up completely must be enough to keep the battery always full

I thought for admission to a absorption refrigerator with the calories available in the cooling circuit.

hello and sorry
I just read your project and I have the same,
reading your project I can tell you that a party that you propose does not optimize performance and some other can even make it fall!
like the fact of driving with ethanol: ecological yes, but not good for engine performance since the calorific value of ethanol is much lower than gasoline!
after improving the cooling is bad too since a very big part of the yield loss is precisely the heat loss of the engine to give an example the race car which plays essentially on the performance make turn their engine between 110 has 150 degree.
for your idea to replace the alternator by thermoelectric generator, the idea is good since BMW has already done that on the 530 they have won 2% consomation

cooling the intake air is a track to increase the yield, provided to change the other parameter of the engine to enjoy it well: in the kind increase the compression ratio ... or simply increase the lead to the ignition
but a cooling absorption will be too heavy, given the fairly large flow of air intake to cool
it is much more interesting to cool the air intake after a first part of the compression: but it's already invented! it's called turbo intercooler!
a single turbo increases power but does not increase performance
an intercooler turbo increases both power and performance
and it becomes possible to prolong the expansion by an additional turbine to the exhaust, and this additional relaxation gives a very interesting total yield
given the high speed it is useful to use this turbine only to make electricity ... a mechanical transmission would be too complicated
this kind of thing already exists for large engine and we get a performance of 50%, and it almost doubles the power of a motor of the same cylinder ... it would take a motor 2 times smaller
finally it's not DIY anymore, it's the true conception of an engine of the future
alas when we see the intellectual level of French car advertising, I do not have much hope to see this kind of solution happen

Ethanol is an ecological disaster.
Otherwise, I like the idea of the electric turbo.

Technical discussions on the polishing of the low-motor, booster pump and other drop in consumption are misplaced on this subject:
