Because it makes no difference whatssoever.
The rotor System of an EC135 in operating conditions will have a stored energy the order of Magnitude of 3-5 MJ.
That is 5 Million Watt Seconds. So a 1600 Watts Night Sun would run for about 1 hour with the energy stored in the rotor.
Would you be so kind and stop pursuing this totally pointless path?
