How to use TEGs to create power with your exhaust heat

No joy unfortunately. It is not one of the repositories tracked by my uni.

I haven't found a free source for the paper yet but it may be of interest.

Here's the paper:

https://sci-hub.ru/ is the place to get papers for free, as they should be!

Sometimes the .ru bit changes as various paywalled sites do their best to keep their 'free income!' as high as possible and shut various servers down.
A search for sci-hub works, but beware of fake sites saying you need to download something/anything before the site will work. DON'T!

Magnesium based TECs look interesting as they are low cost (abundant metals), light and more efficient. Up to 18% efficient!:

Easy Read:
Buzz about thermoelectrics heats up with promising new magnesium-based materials

At some point of efficiency these systems may well INCREASE the power to weight ratio of the complete vehicle, but as 98% of driving is stop-go city driving, until they do; you're better off without them.
Worth keeping an eye on..?

It seems I need to take back my previous post:

Low-Cost Magnesium-Based Thermoelectric Materials: Progress, Challenges, and Enhancements
"...A high-power output of 42.9 W/kg was achieved under a 771 K temperature difference..."

Now an engine has a PWR of ~580 to 1000 W/kg.
No idea what the PTWR of a car alternator is, but pretty sure it's well above 43W/kg.

ie: If you spend most of your driving life at a constant speed on a highway; TECs will help you.
But for 98% of global driving; No.
Which is why TECs haven't been embraced by the motor industry.
