Interestingly, the Boeing 787 has already dispensed with bleed air. It uses compressors for heat and electric pumps for hydraulics.

That's probably less of an efficiency concern, but more likely to avoid future legal cost for supplying contaminated air to the cabin.

Most modern airliners do not use bleed air for climate control in the cabin anymore.

No alternator, but some dc-dc to get the voltage of the main battery down to 14/28 V for the avionics, lights, etc.

The electric motor is not 100% efficient so some heat must be available for cabin. Large synchronous generators are 97% efficient not sure about 100 kw e vehicle

Perfectly agree with everything, but 1.5hr may be very short if you need to have 30 minutes of reserve at landing. On the saving side, you don’t have to have an alternator to transform ICE energy into energy for the dashboard instruments. On the downside, you now need to heat the cabin manually, rather than reusing the ICE heat.
