TERS : Thermal Energy Recovery System

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Anyone taken a look at the recent papers from Albert Boretti (http://profiles.sae.org/79584416411/)? Most are behind the SAE paywall, but some are still available for review. I don't know if this guy is repeating what is already publicly available or is doing original work.

Thanks @subcritical71 these look very interesting.
I’ve looked through the second, dealing with energy flow.

I can’t recommend it. He thinks the H is purely for turbo control and the K is used sequentially during braking, only kicking in when total brake power drops below 120kW. He doesn’t adjust for brake balance. As a consequence he thinks per lap energy recovery at Monaco is zero. There’s more but that’s enough for me.

Yeah, I was also thinking some of his conclusions were a bit off for being in a research paper, oh well!

That and also his conclusion is very shortsighted. He basically sees F1 exclusively as a development tool for road cars, which it never was, at least in my opinion.
You can use the same basic ideas for road cars, but never the specific solutions developed in F1. I mean Mercedes tried that to some degree with the Project one road car and they run into a very real problem, which simply doesn't exist in F1, emission limits.

What a good idea, lets put emission limits in the rules.
