Looks interesting. I don’t see the solar panels though.
Is it going to have to land and recharge the battery every 58 miles or does it use a towed solar array?
Did they fly it there?
Wingtip props mean if one fails, you MUST turnoff the other and rely only on the tail pusher.
It depends on the altitude of emergency onset but with just the tail it's likely the ONLY goal would then be to set down somewhere safe immediately.
Do electric planes have some future?
Yes, I think so.
How good is it at GLIDING?
I agree that electric airplanes might have a future but have a hard time believing the battery technology exists. At least not hauling one ton the distance of 650 miles. Curious if other Freepers might have an insight.
It's nuclear...
Most flying lessons are local. They last about 1 hour.
For that? Yes, now electric planes might be okay.
Another app might be hybrid:
Tons of small airports suffer from noise complaints. What future pilots might do is get the engine warmed up and checked out, then rely for 2 minutes or so on electric for take-off, then switch to gas at a certain altitude.
For long flights, like city to city?
Wow, I don’t forsee that any time soon. I wouldn’t do it.
THAT is a relevant question, and I suspect the answer may be NO...Still, has nice lines, and if anyone can pull it off, I’m guessing the Israelis can...Remains to be seen...
From the Eviation “Alice” website, some specs:
Seats 9 PAX (9+2)
Cabin Pressurized
Cruise altitude 10,000
Cruise speed 260 knots
Range + IFR reserve 650 miles
Energy pack Li-lon - 900 kWh
Service ceiling 30,000’
VNE 340 knots
Approach speed 100 knots
Length 12.2m
Wingspan 16.12m
MTOW6,350 kg
Powerplant 3X 260kW
Batteries not included.
So dissembling required.
What makes it so expensive to
operate is mid-air recharging.
Is it going to have to land and recharge the battery every 58 miles or does it use a towed solar array?
Will batteries of electric plane perform satisfactorily in cold weather? Or is this a hybrid plane?
I remember complaints that some electric cars wouldnt budge when temperatures dropped last winter.
Too small scale
What you need is a huge ground effect plane. The larger the plane, the smaller the proportion of the load for batteries.
I did the calcs a few years ago. You could run a large aircraft, capable of carrying 1000 pax or 150 tons of cargo from SF to LA at approximately 250 mph, all electric, using currently available technology. Ground effect aircraft similar to Boeing Pelican concept. Operating offshore in established lanes.
Quicker than any bullet train at 1/10th the cost.
Hardly big enough to be called an airliner

Propellers make noise too.
Sumpin' doesn't look right about the specs. Even so, and even if the range is only 33% of the above, it's pretty good for only about $100 worth of electricity .
Oh puhleez
“Quicker than any bullet train at 1/10th the cost.”
The Democrats will fix that problem by building a coast-to-coast canal for these craft at a cost of a mere $20 to $30 trillion dollars.
