Alternative engine formula idea

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

The efficiency of advanced MGU's is somewhere around 98.7%

Alternate to your concept. Something I posted months ago in the Honda thread? Keep the current MGUH, but have it attached to a small flywheel, which could be in a concentric layout. Modulated waste gate and BOV. for control. Maximum efficiency.

A number of car manufacturers are moving to electrically driven hybrid supercharger/turbocharger, for road cars. Andy Cowell(Mercedes HPP F1) talked about this recently.

Before somebody says "but that reduces efficiency just remember at present we have to take electricity from a battery (efficiency loss) and turn it back into mechanical energy (more efficiency loss) just to spin the turbocharger. I didn't work out the numbers but I wouldn't be surprised if in a total lap using electrics is less efficient to keep the turbocharger spinning for the low load sections when there isn't much exhaust flow.
Electrical machines are more efficient, less inherent loss, than a mechanical machine? Lag see reply to 2

All the technology is available, and has been for a number of years. The real cost is making versions suitable for F1. I agree with you that the cost of R&D has been passed on to customer teams. I am pretty certain that part of the problem is that manufacturers are so secretive that they want to do all the development of the various MGU's etc as an in-house project. I know that one team buys in the battery cells, to make their own storage unit. Of course they had zero battery failures this year!

Thats 98.7% efficient one way. If used directly in the MGU-K then it will have another conversion factor of (just for this example to keep it simple) 98.7%. That is a total efficiency of 95.6%. That doesn't include any losses through the control systems and wires.

If the electrical energy isn't used immediately then it has to be stored in the battery. What are the electrical efficiency factors when it comes to storing and releasing the electrical power.

My idea wasn't so much about making the PU more efficient. It was an idea that I hoped can maybe keep similar end efficiency numbers while being much cheaper to design and manufacture than the current crop of overpriced PU's with very complicated energy recovery systems.
