...micro APUs running, say, on ethanol. I don't mean run the existing APUs off ethanol, but replace the APU's service battery by a fuel cell or baby motor. It's all interesting from a technical pov and speculation, but the time needed to incorporate the technology into a civilian airliner is ten years.
I use a
baby motor of 24 VDC 300W, motor generator in a motor home and in an electrical bike.
The time to incorporate it (Av) can be much less.
Seems to me that we need to combine every professional in the business to help sort this problem and reassure the public and press. Press and public, more like.
If the 787 fails to meet market approval the consequences on aviation will be deep and bloody. It'll also open the door to the east. I'd rather keep the EU and US duopoly going.
Important moment.
