How high can you fly?

I think the 'electric' powered aircraft is little more than a toy.

If you think you can make fun of me and get a Left seat
on the inaugural flight of my electric 747, you are
nutz.

This will soon be a real consideration.

I don't have the figures available at the moment, but I can tell you what to
look for and what to do.

Find the Vs for a C152.

Find the Mmo, likely about M.75.

Your max altitude is where the true Vs == Mmo.

Thank you so much! Can't wait to run the numbers.

Had this been a contest, you just walked off with a
new trophy.

That video doesn't show it in flight.
This video does.

Cruises...90% efficient, 10% heat.
Max. Climb...80% efficient, 20% heat.

Heat is not a factor.

Replacing the internal combustion engine which
yielded...85% noise and heat, 15% efficiency.

Flys 1 1/2 Hours. And it's beautiful.

Where do we send the check??

you are technically mistaken
in the above assertion because in fact electric airplanes (actually solar-
electric airplanes) hold some world records:

That's not technically. That's actually.

When the solar-electric "Helios" reached 96,863 ft in 2001 it set the
altitude record for highest altitude flown by non-rocket powered aircraft..
So electric (specifically solar-electric) is indeed superior for certain
applications.

I estimated 95,000ft.

Just not general aviation.

Just not general aviation today.

In 2055, you take off burning fossil fuel, "you go jail".

Compared to a real airplane, yes.

There may be some niche applications, like unmanned surveillance, where they
might be useful but they are terribly fragile.

Compared to a real airplane...

AIRPLANE:

engine-driven flying vehicle: a vehicle with wings and a jet engine or
propellers that is heavier than air and is able to fly
[ Late 19th century. French aéroplane aéro- ( Greek aēr "air") + -
plane ]

Any of various winged vehicles capable of flight, generally heavier
than air and driven by jet engines or propellers.

air·plane (er′pl�n′)

noun

a fixed-wing aircraft, heavier than air, that is kept aloft by the
aerodynamic forces of air as it is driven forward by a screw propeller
or by other means, as jet propulsion

And a range of 90 minutes....
That's barely enough to start a crosscountry.
If you want a fun machine that goes places cheaply
The Bantam B22 Microlight has a 4 hour range at 60+ knots.
