KERS is restricted in capacity, use, and power levels. HERS is unlimited. KERS feeds the energy back into the drivetrain, and HERS feeds the energy back into the turbo, each are distinct and separate, although they share the same common control unit and storage device.Actually, it's more complicated than that, the limitations on KERS only relate to a peak power (120kW) and a max transfer from the Energy Storage (eg battery) - the regulations allow for unlimited transfer of power between the two MGUs. This means if the turbo was constantly generating 120kW per lap the driver could permanently power his KERS. There is a diagram at the end of the PDF on page 82.
I like your reasoning, it appears that may be possible. But under hard acceleration wouldn't you want the MGU-H to spool up the turbo, thus not allowing it to harvest heat energy to feed to the MGU-K just when you want it? I can definitely see the MGU-H feeding 120 kW (as long as it's not robbing the engine of any power) to the MGU-K at the end of the straights, long after KERS is traditionally not used. Fascinating stuff, I can't wait to see how the teams decide when and where to use ERS and how the power is shuttled about.
Thanks Alien, suddenly it just got very interesting.
