| ▲ | dang 6 hours ago | parent | next [-] | | Can you please not be snarky in HN comments and not post shallow dismissals of other people's work? Both of these are in the site guidelines, as you must know: https://news.ycombinator.com/newsguidelines.html. There's room for thoughtful skepticism and critique, but not dismissive sarcasm, nor supercilious putdowns like "Yeah...", "just a joke", "yet another high wing puddle jumper". All that is exactly what we ask commenters to avoid on this site. As the guidelines say, "A good critical comment teaches us something." Your account unfortunately has a long history of breaking the site guidelines—enough, I'm afraid to say, that I instinctively brace myself when I see your username. We've asked you about this multiple times over the years: https://news.ycombinator.com/item?id=29222114 (Nov 2021) https://news.ycombinator.com/item?id=25697507 (Jan 2021) https://news.ycombinator.com/item?id=21094881 (Sept 2019) https://news.ycombinator.com/item?id=20314315 (June 2019) https://news.ycombinator.com/item?id=19469358 (March 2019) If you wouldn't mind taking the intended spirit of this site more to heart and really correcting this pattern, we'd appreciate it. You're obviously knowledgeable and a good commenter apart from this, but it's a problem. | | |
| ▲ | ajross 5 hours ago | parent [-] | | Fair enough. I'd view it as "florid" vs. "shallow", but it's not my opinion that matters and I fully agree that there's a spectrum between "strongly held" and "offensive" and you have to put the boundary somewhere. I'm going to push back on one bit though, which I suspect is just a misunderstanding on your part: "yet another high wing puddle jumper" is not remotely dismissive or trivializing! Being "high wing" is purely descriptive, and correct, and a "puddle jumper" is a widely used term for short-range passenger aircraft (like the Dash 8, which I also mentioned), here's a great reddit thread for reference: https://www.reddit.com/r/etymology/comments/rs7i4m/what_is_t... I'm not saying this to make the designers feel bad verbally. I'm literally saying they've produced an aircraft that competes poorly in the market with something DeHavilland was selling in the 1980's. My first sentence was almost 100% sarcasm though and I'll take the hit on that. | | |
| ▲ | dang 5 hours ago | parent [-] | | I take your points on "high wing" and "puddle jumper", especially the latter since I didn't know the term. But "yet another" is still a dismissive swipe! I appreciate the reply. |

| ▲ | chrishare 6 hours ago | parent | prev | next [-] | | The video cites the large number of existing flights that are short enough for the electric. I am not sure they should be judged based on whether they make air travel more appealing overall - making it cheaper and lower emission is plenty. | |
| ▲ | bdamm 6 hours ago | parent | prev | next [-] | | 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. | | |
| ▲ | rbanffy 4 hours ago | parent [-] | | > Designs that distribute props across the leading endge, or right on the leading edge of the rudder, are exciting From a purely aesthetic point of view, pusher props are way cooler. If the wings are far back and the plane has canards, even cooler. |

| ▲ | pkulak 6 hours ago | parent | prev | next [-] | | 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. | | |
| ▲ | HolyLampshade 6 hours ago | parent | next [-] | | Man, I’d love more trains but we can’t act like the infrastructure necessary to support them, if not present, is very challenging to develop. Even ignoring land acquisition (which is a big thing to ignore in populated areas where a train would most benefit the population), there are simple things like road crossings, other infrastructure crossing, etc. In this case an airplane may be simply a lower friction solution. | | |
| ▲ | mr_toad an hour ago | parent [-] | | The biggest costs and sources of delays to building high speed rail in the UK are legal challenges from people who don’t want any construction to take place anywhere near them. |
| |
| ▲ | chrishare 6 hours ago | parent | prev | next [-] | | Trains are great, but they can only go where tracks go. Planes are faster, too, noting that boarding times can dilute that. Trains are perfect for freight and super frequent routes, though. | | |
| ▲ | tmtvl 6 hours ago | parent [-] | | Commercial passenger planes can generally only lift off and on at dedicated facilities, though. | | |
| ▲ | 7952 5 hours ago | parent | next [-] | | Those facilities can be much more modest and can scale up and down depending on location. Particularly for smaller short haul aircraft. | | |
| ▲ | pkulak 3 hours ago | parent [-] | | Maybe. But they can almost never be in places where people actually need to be; like central cities. |

| ▲ | boelboel 6 hours ago | parent | prev | next [-] | | It's not about moving hundreds of people, it's about moving 30-100 people. Many places don't have the demand or physical possibility for a railway. If this wasn't the case there wouldn't be so many short distance flights. | | |
| ▲ | pkulak 3 hours ago | parent [-] | | > Many places don't have the demand or physical possibility for a railway. This I don't get. I've seen rail stops in the smallest towns, where the train stops for 30 seconds to let a couple people on or off. Places where even the smallest airplane makes no sense at all. Not 30-100, 1-2. |

| ▲ | 7952 5 hours ago | parent | prev | next [-] | | But politically and financially it is very challenging to build new capacity in a lot of places. | |

| ▲ | runako 7 hours ago | parent | prev | next [-] | | > 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? | | |
| ▲ | bryanlarsen 3 hours ago | parent | next [-] | | According to the video, 2/3rds of that range is for loiter and divert capability. It's illegal to fly a route without the capability to loiter and divert. You need 30-60 minutes of loiter + 100 miles of divert. This plane cannot be used on any route longer than about ~200 miles. Which can be driven in 2 hours, although obviously the OP was referring to the 120 mile electric range. | | |
| ▲ | arjie 2 hours ago | parent [-] | | > This plane cannot be used on any route longer than about ~200 miles. Which can be driven in 2 hours. Huh, perhaps then it wouldn’t be suited to places where people drive at that speed. In the US I doubt people drive 200 miles routinely in 2 hours. It would be closer to 3.5 h I think going by the routine 6 h it takes SF to LA which is about 350 mi. I think if you have very high speed road/rail transportation that dominates this across fixed routes. Road at 100 mph average definitely wins for flexibility. |

| ▲ | RajT88 6 hours ago | parent | prev | next [-] | | Gotta be Germany and the Autobahn. The questions really are: What car are you driving? How are you not dead? | | |
| ▲ | jillesvangurp 5 hours ago | parent | next [-] | | 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 much of the way you'd be facing speed limits. And traffic jams. | | |
| ▲ | RajT88 5 hours ago | parent [-] | | runako was making a joke about someone's grueling drive of 500 miles in 2 hours. ...Which would mean you're driving at 250mph. | | |
| ▲ | rbanffy 4 hours ago | parent [-] | | “250mph” AVERAGE speed. Most cars take off at that speed. | | |
| ▲ | RajT88 2 hours ago | parent [-] | | Most cars burn their engines out long before that. But damn, if it would not be fun to melt an engine driving at the redline in a straight line. |

| ▲ | ajross 6 hours ago | parent | prev [-] | | 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. |
| |
| ▲ | ajross 6 hours ago | parent | prev [-] | | 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. | | |
| ▲ | patapong 4 hours ago | parent | next [-] | | 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. | |
| ▲ | MBCook 6 hours ago | parent | prev | next [-] | | Island hoppers? Very few highways between the Hawaiian islands. Or Caribbean. Probably plenty of other places. There are tons of places in the world with short haul flights today, even if good highways exist. Every one of those planes is a potential target for replacement. You’re arguing most short haul flights shouldn’t exist. Maybe do, but they do. | |
| ▲ | notahacker 5 hours ago | parent | prev [-] | | I mean, for the all-electric distances it's pretty much a given that it's cheaper: fuel consumed is the largest item on airlines' expenditure. The bigger question is at what distance you start having to burn more fuel than if you weren't lugging batteries round with you. If it's [eventually] commercially competitive at 400m range it's going to be useful on a variety of routes currently operated by ATR-42s and Saab 340s etc, the sort of thing that's definitely not operated by 40 year old 9-seaters. If it isn't... well islands still exist, they're just a fairly small niche |

| ▲ | mikeweiss 7 hours ago | parent | prev [-] | | I feel as a civilization we are further behind in battery technology than we should be at this point. | | |
| ▲ | ajross 6 hours ago | parent [-] | | It's chemistry, not technology. Motive engines that can suck ~70% of their reactant mass from the atmosphere have a horrifyingly unfair advantage. | | |
| ▲ | the_gastropod 4 hours ago | parent [-] | | I'm far too dumb to understand the intricacies of such technology, but the continued research into Lithium-air batteries seems incredibly inspiring. If we can figure that technology out, seems like it'd unlock a whole host of battery-powered transportation options. |
