So you are finally giving up on your assertion that a sealed brushless
motor is magic and won't need cooling?

Who ever said that a sealed brushless motor is magic
and won't need cooling? I certainly didn't. This is just another
example of your revisionistic debating style.

This doesn't mean you cannot have electric airplanes, or that
at 20,000 ft. they aren't superior to internal combustion.

Electric airplanes are not and will not be superior to ICE airplanes
at any altitude any time in the foreseeable future.

Most people are unable to see beyond today. I don't
envision heavy low-density batteries. No ICE dragster
can beat an electric one. That's real now. Yes, it's
short run. Yes gravity isn't a factor. But people are flying
electric planes today. That's real. Billions are being spent
on a better power technology...and I believe they're going
to make it and when they do...I will retrofit a plane
such as one that currently is an LSA.

There are already GA aircraft that regularly fly at flight levels, though
most of them that go much over 20,000 feet don't use pistons in the engine.

And if they didn't need oxygen for combustion...

There is no market for small, as in C172 size, airplanes that can get to the
flight levels or someone would already be making them powered by small
turbines.

That's because it's too specialized. An electric plane can fly
at any elevation it want's to under the stratosphere until air
density prevents lift, or cooling is impossible. Therefore a cheap
retrofitted small plane would simply fly over inclement weather,
changing the paradigm of general aviation. And, the fun level
would be off the chart.
