These kind of startup excite me. More so than the "next killer app" or "look what we shoved AI into." Cheap electric transportation can finally offset USA's lacking rail commutes and attack Europe's short flight market (which is already cheap). Now we need bigger planes or more frequent planes and the next startup to solve the energy needs.

> Cheap electric transportation can finally offset USA's lacking rail commutes

I'm not sure how building an electric aircraft would help with this. Are people going to suddenly switch to commuting by plane?

Fixing America's commute problem is primarily an urban planning one (ie, putting all the homes nowhere near anything) and not an insufficient-electric-aircraft one.

Earlier quoted context omitted.

I live in Germany. 500 miles is more than essentially all domestic flights in Germany. Two hours driving by car from Berlin gets you nowhere all that interesting. You'd probably spend close to an hour just getting out of the city. Two hours might get you as far as Magdeburg or Dresden when traffic is mild. Good luck with that on a busy weekday. Dresden would be about 200km. Magdeburg is a bit closer to 160km. And muc…

runako was making a joke about someone's grueling drive of 500 miles in 2 hours. ...Which would mean you're driving at 250mph.

“250mph” AVERAGE speed.

Most cars take off at that speed.

Is this EV or Hybrid?

The founder seems to sneak in the word "hybrid", around 1m30 mark in the video below.

Note: not being negative, I just want to ensure I understand correctly since the title might imply something else.

Update: confirmed, it does use aviation fuel.

> "The airplane will also include a reserve-hybrid configuration, consisting of two turbo generators powered by sustainable aviation fuel. The reserve-hybrid system is installed to secure reserve energy requirements without cannibalizing battery range, and it can also be used during cruise on longer flights to complement the electrical power provided by the batteries."

> 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?

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…

It might be cheaper when internalizing the externalities of CO2 emissions. Once/If we start properly taxing the impact of these emissions, this plane could offer much cheaper flights then fossil fuel driven competition.

Could you imagine the (rather justified?) NIMBYism for all the airports required for commuter flight? If rail can’t be done, flight definitely won’t fly.

Hybrid after the first 125 miles, total range 500 miles. Their problem is diversions - an incident at the destination airport may mean an passenger aircraft may need to land at an airport which could be a couple hundred miles away. The hybrid powerplant throws the fuel efficiency numbers off so goal is not to run it unless needed, but they could not get certification without it.

With limited information form their web site, both. Being able to run pure electric while switching to fossil fuel. [0]

The way modern hybrids can charge from an outlet, I classify them as EV-Hybrid, and only use gas if need be vs older ones that only charge through the gas engine, Hybrid.

I'm not sure I get the 'appreciating asset' point he makes in the video. How will the plane perform better in 10 years? Cool stuff regardless!

That made me double take too, but he must be talking about the software getting better, and thus higher value.
