Electric airplanes will be next

Are you ready to wheego?

Or pick an electric car from this
old list from 2 years ago?

World's fastest electric car:

Here's a nice one!

Sorry, but these links only show a fraction
of what is actually happening to date. Every
single one of these cars is using battery
technology that is about to be replaced with
a ten-fold battery density improvement.

New electric cars are better.

Oh boy, a two seat cracker box that goes 100 miles max and costs over
$30,000.

Yes sir, they will be lining up to by those things.

Most of those are not cars and several have already gone defunct.

Whoopee, an Ariel Atom with an electric motor!

Yet another one off wonder.

Yet another over priced techo-toy that exists only as a prototype.

Sorry, but these links only show pathetic crap.

True, perhaps, but electric airplanes are coming. Folks are building
them. Folks I know who build airplanes and also electric trucking
equipment are waiting for battery technology to come up a little. For
example, NiCad batteries are obsolete. Lithium ion is obsolete.
Lithium polymer (LiPo) is awesome, but, if you've ever seen one of
those things overheat and go incendiary, you'll never put one in an
airplane.

Turns out if you yank out your Lycoming, all of the fuel systems, oil
systems, fuel tanks, fuel, oil, etc, you end up with a really light
aircraft, a vacant space on each wing for batteries, plenty of room
for an electric motor/gearbox, a spare battery by the firewall to use
as your reserve and provide the ballast eliminated by the internal
combustion engine.

Ten years ago you'd have been called a treehugger or dreamer out here
for suggesting such a thing might exist, but, ten years ago LiPo was
something obese people had done. Stuff is happening and it's
comforting that the people I know who are telling me about it are out
flying their home built airplanes waiting for the next generation of
batteries hit the industry.

The same could be said for a tank full of avgas.

And absent some astounding unforseen breakthrough in battery technology
they are going to grow old and die waiting for a production battery
system that will power a practical airplane other than a motor glider.

The range of pure electric cars is crap and the price makes them toys for
the "eco aware" rich.

The only pure electric car in production with anything like a useful range
is on the order of $100,000 and does not have to meet any of the requirements
that an airplane does.

Care to guess what an electric 172 with the range of a conventional 172
would cost?

The Cessna proof of concept electric 172 is shooting for a whole hour on a
charge, which gives it a legal range of about a half hour of flight before
"refueling".

A tank full of gas doesn't get hot because it is being used but batteries do.

I'm sorry, but battery technology will never get there! It like carrying
all the air you use in an IC engine (IOW, a rocket), rather than just
the fuel and gathering the air as you go (present method).

At 15:1 air/fuel ratio, you would have to carry 90# of air for every
gallon of fuel, so a battery equivalent would have to weigh (50
gallons*6# + 50*90# air = 4800#) -- just in equivalent energy.

Lycoming + prop = 450# + 300# fuel = 750#

This is assuming that you can get equivalent energy storage, which is a
LONG way off!

A friend of mine pointed out that although gasoline needs to have
oxygen added before it can burn,

What does your friend think caused TWA flight 800 to explode, killing 230
people?

Other incidents include one in 1990 in which a Philippine Airlines 737-300
fuel tank exploded and another in 2001 in which a Thai 737-400 jet's fuel
tank exploding while sitting on an apron at Bangkok airport.

And of course you'll find many examples of general aviation aircraft
catching fire during fueling - sometimes because grounding isn't done, or
is done incorrectly.

a battery already contains everything
it needs to explode.

That just makes for another good reason to avoid cell phones. ;-)

Battery explosions are relatively muted compared to fuel vapor/air
mixtures. Batteries don't have that much energy - or energy density - to
make them as dangerous when they explode.
