Dave, it's time for you to stop complaining and just admit electric is simple.

After it failed during the last two comps I took it to?
Drive for days, fly a few times, then drive for days home after it breaks?
I don't think so...

Anyway, no vaccination yet so no travel in any case.

The Antares was a bold effort, perhaps too bold, and by now, it's an old effort. No point in
holding it up as an example anymore. Now, all the manufacturers have electric gliders, and Solo
has added electric systems to their sailplane power business. Electric isn't the coming thing
any mo it's here. The next milestone will be passed when they start selling more electrics
than ICEs.

The market wants:
Fast charge for convenience
Safety
Long life for low cost of ownership
It is possible to get the send two if one compromises on the first.
Can't have all.
Balancing packs requires time.
Unbalanced packs fail or die sooner.

Just reading about the Lilium electric air taxi in Forbes, they want to
draw 1.2 megawatts from the batteries for 60 seconds for vertical
takeoff and transition to forward flight.

You can do that sort of thing for 3 seconds in a Tesla for Ludicrous
mode, but 60 seconds can fry the batteries in the air taxi.

Tesla has 4000 small cylindrical cells, with a manifold in contact with
all of them, with pumped liquid cooling to allow high charge and
discharge rates.

Most electric gliders just use big pouch cells, a lot of people just
don't understand the implications of that.

Lilium has raised 400 odd million bucks in funding, looking more like a
pipe dream all the time. Ditto for that Alice thingie, but they've only
burned 200 mil.

1.21 Gigawatts for 60 microseconds and you can go back in time. Or you'll be history. Or something like that.

Now, where did I leave my Segway...

There's no law saying that investors have to be smart.

Oh that is so last decade. I've got an InMotion V11 instead, and the
bruises to prove it!
