Heart Aerospace (YC W19) just flew the largest electric airplane ever flown — a 100-foot wingspan, a takeoff weight of 25,000 pounds, and $5 of electricity to get it off the ground.
Scrimptech•2d ago
Hope it's accurate. Sounds good to be true.
kooi•2d ago
From the video:

Range: 125 miles all electric

       500 miles with hybrid system (electric + conventional turbo prop)
ajross•39m ago
At last! Enough range to allow a few dozen passengers to spend ~3 hours getting to and from airports to replace the grueling two hour drives they'd otherwise be forced into making.

Yeah... this isn't going to do it. Maybe there's an argument for this hybrid plane in the regional airliner market if there's a significant fuel savings vs. turboprops (the linked video is silent on the subject, but it's plausible).

But the "all electric" bit is just a joke.

Edit to point out: this company is less sexy, but has made the same design mistake Boom did: they designed a physical airframe for what is actually a propulsion problem. Boom's story about how they're going to push their plane has changed like six times now. And likewise what this startup should be hawking is a hybrid turboprop that they can sell to Bombardier or whoever.

I mean, who cares that they built yet another high wing puddle jumper? That's a 60-year-solved problem. It's the stuff in the nacelles that matters!

> 500 miles with hybrid system

> the grueling two hour drives

What country are you in, and perhaps more importantly, what roads are you driving on?

ajross•27m ago
To repeat: the market is filled with fuel-driven turboprops. This only wins if it's better, and it's only better if it's cheaper. Is it cheaper? If it's cheaper they should say, and not spend time talking about "all electric" range in a regime that doesn't want aircraft at all.

And sure, there are places in the world that don't have limited access highways. But the 125 mile range is already served very well by piston-driven lightplanes! Again, who's going to buy one of these vs. just continuing to run their 40+ year old Beavers or Caravans or whatever?

Also: if the only market for your high tech electric superplane startup is backcountry work in Alaska, you're probably never going to get funded to begin with.

RajT88•17m ago
Gotta be Germany and the Autobahn. The questions really are:

What car are you driving?

How are you not dead?

ajross•6m ago
Both of you are misunderstanding the point: I was responding (pretty clearly I thought!) to the ridiculous "all electric" range.

Yes, it can go farther if you burn fuel. But so can a Dash-8, very effectively. No one is interested in hybrid range per se, only if the hybrid mode is more efficient.

I feel as a civilization we are further behind in battery technology than we should be at this point.
ElijahLynn•2d ago

mmcconnell1618•27m ago
Interesting decision to build the whole aircraft instead of the propulsion system only. I wonder what the decision process was between retrofit of existing turboprop frame vs. build from the ground up? I would expect the level of effort and certification to be much higher building from scratch even though you get complete control.
lbriner•6m ago
Judging by the seats, perhaps making it as light as possible. Existing airframes are relatively light but let's be honest, they aren't trying to save 500g here and there when they have massive jet engines to get everything airborne.
tristanj•20m ago
The interior of the plane is clearly designed by an engineer. They stripped everything down to save weight, passenger comfort be dammed. The seats don't even look comfortable.

They need to hire an actual designer, if the plane weighs 0.5% more but has actual human usability that's worth it.

ajross•26m ago
It's chemistry, not technology. Motive engines that can suck ~70% of their reactant mass from the atmosphere have a horrifyingly unfair advantage.
bdamm•32m ago
I'm pretty excited for the hybrid airplane. Use battery charge to get up to altitude. Hybrid power during cruise and top off the battery with the leftover power. Far less power requirements, far less fuel use, better climb performance, and can use the most efficient engine rather than hugely inefficient but power dense turbines. And as a bonus, put the prop power anywhere you want. Designs that distribute props across the leading endge, or right on the leading edge of the rudder, are exciting.

What an age to witness.

Can I be the one to make the obligatory train comment? Moving hundreds of people 500 miles in comfort, using only electricity, is also a VERY solved problem.
