    It just occurred to me that with the recent advancements in cargo-container-sized nuclear reactors, they would excellent fit to power aircraft due to the high energy density. There were attempts at nuclear-powered aircraft in the past using older technology, but IIRC they irradiated crews and were primarily for bombers carrying nukes that would supposedly need to be in the air continuously for days at a time.

      Because they didn’t. And anyone that is capable of critical thought can easily take the few numbers they provide in the article and do some simple calculations.

      They claim the motors pull more than 1mw of power. So using 1 mw for 30 minutes is 500kWh. That means they paid 1 cent per kWh. (Spoiler. They dont)

      And nowhere, does it say the plane weighted 25000 pounds. It says it “can exceed” 25000 pounds. But by no means does that mean that’s what it weighted in this test.

      The most likely scenario is that the plane was bare minimum rather than maximum. I doubt even passenger seats were installed.

      This plane is a piblicity stunt and will never be a viable product (the company itself said it is not meant for commercial production)

      This “jet” has a lower max speed than a Cessna 150, a service ceiling of 2,000 AGL - far less than any commercial aircraft. It weighs 25,000 pounds with no passengers or cargo, almost certainly it’s max weight. They can’t even fit a 2nd pilot

      They do not disclose how much energy was actually used, just a vague “$5” figure and a listed max power of 1MW

      It’s just a marketing ploy and you fell for it

      There are also flights where this could be used as fully electric right now, or very soon if they increase range a bit. If you fly from Tallinn to anywhere via Finnair, you go through Helsinki, that’s like a 30 minute flight. And the reason you don’t just drive to Helsinki is that you’d have to take the ferry which costs more money, takes over an hour and the Helsinki airport isn’t that close to the port.

      Similarly, you can fly from Tallinn to the two bigger islands here in Estonia, very short flights versus like a 3 or 4 hour bus ride involving a ferry. 30 and 40 minute flights with the current 30-40 person planes that company uses.

    Oh boy… So, they took off from a test facility adjacent to Plattsburgh International Airport. I don’t see it stated, but I give it 98% they landed where they took off. Plattsburgh has some of the lowest residential and commercial electricity costs in the country, so that $5 nets them about 110kWh of juice.

    They also reached a maximum altitude of 1,100 feet with a plane that weighs in excess of 25,000 pounds. Lifting 25,000 pounds up to 1,100 feet takes 37 million joules of added potential energy, or a bit above 10 kWh.

    The entire remaining 100kWh of energy budget is the equivalent of accelerating the 25,000 pound aircraft up to 252 meters/second at perfect efficiency in a vacuum. This flight was not going very high, and it was not going very fast.

    If the economics of their hybrid idea work out, it’ll be fantastic, but the attempt at marketing over transparency here doesn’t fill me with optimism.

      They didnt say the planes weighted 25000 pounds. They said it could exceed 25000 pounds. My guess is that not even the passenger seats were installed in this run.

      1mw of power from the 4 engines. For 30 minutes, 500kWh. So for $5 they paid 1 cent per kWh. Somewhere there’s a bunch of bullshit hidden.

    If they can fly a small airliner for 30 minutes for $5. Either there’s a whole lot they’re leaving out. or they’re not paying anywhere near what I pay for electricity.

    They say the engines delivered more than 1 megawatt of power. Cool, so 1 MW over 30 minutes. That’s 500kWh. Which means if they paid $5 for it. They paid 1 cent per kWh. Now i don’t know about you guys. But i sure as hell don’t pay 1 cent per kWh.

    they also dont specify how many kwh they used. which is why i assumed a sustained 1mw of power. they also dont say how much the plane weighted. only what it could potentially carry. that doesn’t mean that’s what it weighted in the test.

    don’t get me wrong. cool stuff to fly electric planes. but i can’t help but feel incredibly sceptic when they leave out a lot of numbers while making the insane claim that they only used $5 worth of electricity.

        For most airlines the biggest cost is fuel, they reliably make the money back on the planes themselves because they run them for 30 years, so it’s a long-term investment but it will pay off.

        Over the 30 years this aircraft could theoretically be in operation fuel costs are going to skyrocket. So not only is it saving some money today, it’s saving a lot of money tomorrow. We may even get to the point where aviation fuel becomes literally unavailable, an electric aircraft like this is a pretty good insurance policy. But you do have to buy a whole new aircraft, and maybe you’ve still got 20 years on your current one, so you need to make that money back, and one of the best ways to ensure that you pay off that cost is to have more customers, and the best way to have more customers is to have cheap fairs. You can afford cheap affairs because you’ll feel costs a lower.

    This seemed intuitively wrong to me (like, way too low a cost), but: 25,000 pounds moving 100 mph is equal to 11,331,007 J of kinetic energy. Since 3.6 million J equals 1 kWh and 1 kWh on average costs $0.17, that means you could accelerate 25,000 pounds to reasonable bare minimum flying speed for about fifty cents (not considering efficiency of the machinery). My mind still can’t process this, but math is math.

    Since a plane requires the most thrust at takeoff, you could use ground-based catapults to get the plane to takeoff speed (or faster even) and then you could carry smaller batteries and propelling machinery.

    For extra fun, you could have landing planes snag a wire and use their momentum to accelerate a plane taking off.

      yeah it’s pretty crazy how much energy is in fuel.

      1 kg of oil contains about 30 MJ of energy. enough to accelerate an object of the same mass to 7.7 km/s. which is almost escape velocity on earth (11.2 km/s), or enough velocity to shoot the object out of earth’s gravity field altogether.

      (a kg of oil, ofc, costs about $1)

      One important caveat to this. It costs less than 17 cents to generate 1 kwh. Closer to 3 cents really. But that’s the cost of making the electricity, getting that electricity to a house or charger or what have you costs more. Since energy is a for profit industry they tack all the logistics costs to the client buying the electricity.

      So your math is spot on but I fear the amount of markup on the electricity will be massive especially since it’s for a business let alone an airline.

        National average it’s 55¢ to run 3kw in 3ph electricity for an hour. Offshore areas like Hawaii and Alaska see higher costs like 1.60$/hr per 3kw on 3phase electricity but Alaska has a higher natural gas usage and Hawaii is further away from the CONUS electrical grid. National average per 24/hrs of charging is a little over 13$ with 3kw at 3phase.

        Landing yes, it’s kinda silly to try to implement arresting cables for landing anyway. Takeoff though? If the system is broken, well then takeoff is delayed, but that wouldn’t be an emergency. Planes can’t take off all the time because of weather conditions.

      Actually dragging (or wheeling in) a wire or having a wire car supplying the plane with electricity during takeoff would work too.

      I think the only realistic use case is going to be short trips. For long range offsetting the carbon for jet fuel just makes more sense.

      But really small personal vehicles could be interesting. There is the Pivotal BlackFly which can VTOL and uses less electricity than a big electric car - and it needs to roads. So for commuting this could actually work to save on infrastructure.

          Can you imagine the chaos of hundreds of thousands of flying cars all trying to takeoff or land at the same time during morning and afternoon commutes. It would be glorious to witness, minus the human carnage. Even with the help of air traffic controllers there are still collisions with the current volume of air traffic. In a word, unworkable.

          Two obvious solutions to traffic congestion in the US are work from home and replacing the public transport networks that automobile and oil interests dismantled.

        Actually dragging (or wheeling in) a wire or having a wire car supplying the plane with electricity during takeoff would work too.

        After doing more of the math, I realized that the energetic cost of takeoff is quite a small fraction of the overall cost. So the only real benefit of the catapult would be to reduce the size and weight of the propulsive machinery on the plane. So externally providing just the electricity wouldn’t be much of a benefit.

    Every time I hear of an all electric aircraft of any size, I always wonder what they’re going to do about landing weight.

    Every modern transport category jet has a higher takeoff weight than landing weight, because of the simple unavoidable fact that landings are rougher than takeoffs. Taking off, the load gradually comes off of the landing gear, on landing it’s suddenly applied. Jets burn tons, literally tons, of fuel enroute, so they’re considerably lighter on approach. It’s why aircraft have dump valves to jettison fuel overboard in case of forced landing early in the flight.

    Batteries don’t get lighter as they’re discharged, so…?

      That’s ridiculous. No one on final gives a crap about take-off weight. What you need is a ride in a glider or parachute. Learn to land on your ride’s minimal weight. Dropping stuff is only an extra measure if possible, not a necessity.

      The same way we make bigger aircraft with higher landing weights: beefier landing gear and structural reinforcement. Airliners don’t have a lower max landing weight than takeoff because they have to, they do it because it’s cheaper and more efficient. Add some more structural weight and you lose some payload, but if the efficiency gains from fuel cost savings make it worthwhile, then manufacturers will make them.

          That’s true regardless, batteries will never power intercontinental wide-bodies (short some major new developments in battery design). This will probably reduce the maximum aircraft size where batteries remain viable, but they are obviously very viable for short hops in small jets, the point where they cannot compete is somewhere but it’s not “never”, even with this limitation.

          That all said, maybe someone will explore just dropping batteries along the way? It sounds ridiculous, but it also sounds like something we have the tech to solve…

          It’s a bigger deal on bigger aircraft, but on mid-size narrow bodies it’s not as much of a problem. A 737, depending on the model, only has a difference of about 20-30k lbs between MTOW and MLGW and no fuel dump capability. An overweight landing isn’t really a big deal in one, just a quick maintenance inspection. Closing the gap so MTOW and MLGW are equal is doable. It’s hard to overstate how huge of an expense fuel is to an airline, if they have to lose some passengers and cargo they would absolutely do it if it got rid of the fuel expense.

          Of course all that is contingent on having batteries with enough energy density to get somewhere close to current MTOWs while having something of a useful range.

      You can rethink the engineering with electric motors.

      The planes you are describing are designed assuming they will be lighter on landing because of fuel. So why design them for take off weight?

      Electric motors are condusive of blown wing design for example, and would have a unique landing profile. (The plane can land at much slower velocity)

      Edit: yeah they’ve moved the engine shroud which allows for lower speeds. Given the same runway you would be able to trim vertical speed.

        You can rethink the engineering with electric motors.

        One of the other limitations is that you’re stuck with propellers if you’re using electric motors, so your top speed is going to be significantly slower than jets. Unless you do the Tu-95 thing with contra-rotating props whose tips exceed the speed of sound, and then you have monstrous noise problems.

        That ain’t gonna happen on a civilian airliner.

        Blown wings are basically powered lift. You’re planning on bringing a civilian passenger plane down final approach at a speed it can’t glide at if the power plant fails?

        I could see that for a carrier based aircraft where STOL is a factor but no you’re not doing that in airline operations.

          Why couldn’t it actually be safer since you could have distributed power centers, across multiple motors?

          You could also have hybrid approaches - there is space between not being able to glide and smashing your landing.

          I’m just getting at it being a different system so some old assumptions can be reexamined.

          Bigger challenge than landing is energy density.

          Regardless it’s a very interesting space.

    I did my best to find any technical data about the flight. Couldn’t find any actual numbers. FWIW it’s not intended to be a standalone method of powering the aircraft for commercial use; they plan on making it a hybrid, which makes far more sense as far as range and payload are concerned. Best guess a 25000 lb aircraft like this will probably cruise around 120-150Kt at a nice, slow, efficient airspeed for a test like this. So maybe a 40-50 mile flight because “air time” probably started as soon as they lifted off.

      Yeah the problem is they also don’t tell us the load during the flight. From the lift equation (let’s be hand wavey) if they’re a similar size to a regional jet (same planform area) your heavy lift is better driven by speed than lifting coefficient. Of course, it’s hard to go fast with electric props, so I wonder if a safe ceiling is probably 400Kt 300Kt?

      Gives a nice range of you know… 40 to 200 150 miles.

      Edit:

      No way. The speed record for a prop aircraft currently stands at about 300Kt. If we use that generously our new ceiling is lower.

        It’s right there, friend.

        25,000lb. Reading the article it says “more than 25,000 lb”.

        We should assume they used a highly efficient airfoil that can maintain the most efficient possible cruise for the demonstration aircraft probably at L/D max if they’e looking for time aloft, so I doubt it’s even worth considering top speed or ceiling. It would be interesting to know what NACA profile they used and what the top speed characteristics would be.

        Edit: looks like a Vne of 140 Kias. This is not a fast aircraft. Also a minimal useful load. If you make a couple clicks through to the site of the test it’ll give you more info.

          The first flight of the largest battery-electric aircraft to take to the skies lasted nearly half an hour while costing just $5 of electricity.

          The X1 aircraft is comparable in size to a small regional airliner and can achieve a maximum takeoff weight exceeding 25,000 pounds with the help of four wing-mounted electric motors. The battery-electric propulsion system delivered more than one megawatt of power during the maiden flight.

          It doesn’t tell us what the load was for the test flight at this price point.

          You’re probably right that it is good and slow and much less weight.

          Likely a short flight.

        $3.60 for mogas at a couple places near me. Very high density altitude, well leaned out, in slow flight, you could get 27 minutes out of a 150 for $5

        These guys are also apparently getting electricity for 2-4 cents per KWh, which is many times cheaper than most would be able to get it

        You’d even have more useful load than this “jet” that can carry no passengers or cargo

        You could also fly a glider. It’d be as useful as this thing

      Well, the data we do have is that the flight was just under 30 minutes and very likely under 100 miles.

      From the Wikipedia on airline fuel efficiency:

      The worst-performing flights are short trips of from 500 to 1500 kilometers because the fuel used for takeoff is relatively large compared to the amount expended in the cruise segment, and because less fuel-efficient regional jets are typically used on shorter flights.

      In the example values table, the most efficient plane for a 560km trip burns 0.92 kg of fuel per km, so doing some rough math and assuming the electric plane travelled 100 miles, that would be roughly 148kg of fuel, or 50 gallons (190L).

      At current jet fuel prices ( $3.76/gallon ) that’s about $188 US in jet fuel as a rough estimate. It’s unclear if the test flight went up to full altitude or if the plane was at full weight, so a fair comparison might have used even half as much jet fuel.

        Jets are less efficient because they’re designed to carry large amounts of cargo and/or passengers. This plane was at near max weight, 25,000 pounds, with zero cargo or passengers

        The entire thing had to be stripped down. Single pilot op because they didn’t have the capacity for a 2nd seat and pilot

        All this “jet” can do is transport its own batteries short distances, slower than a Cessna 150, and very low altitudes

        27 minutes of slow flight in a 150 at high density altitude, well leaned out, would cost about the same and have the ability to carry a passenger

        This plane is nothing more than a marketing ploy. At least it’s quite effective at that

        $5 of electricity to lift an airplane 10,000 feet definitely seems low.

        If you want to be really smug, you could say a gas powered plane requires $0 of fuel to glide for 30 minutes

          Now that you mention it, they specify a maximum total weight of 25,000 lbs, so at 100% efficiency it would take 339MJ of energy to lift the fully loaded plane to 10,000 ft. That can be converted as 94 kWh, and at the current cheapest electricity price in the US of $0.1235/kWh, that’s $11.63

          Therefore, it is literally impossible for this plane to reach 10,000 ft for $5 fully loaded.

            Way cheaper than I’d have guessed.

            737 at max takeoff weight is 175k lbs. So that’s around $80 to get airborne. Seems like a steal when you’re charging easily triple that for one seat.

              To be clear, this is the theoretical minimum amount of energy to lift a mass straight up. I’d be surprised if an airplane moving sideways would hit even 30% efficiency in comparison.

      Why would you leave behind a perfectly nice airstrip when your goal is testing a new aircraft? One step at a time, Speedy. Aircraft distance depends on altitude and winds. Not the goal of this flight to break this kind of record. Easier things like time come first. Only then can they calculate how far they can go. Aircrafts can’t park on the shoulder like your 2D vehicles do.

      Heart aerospace’s website indicates the X1 demonstrator has a 140kt “VNE” - never exceed - speed. So it’s probably safe to assume cruise speed would be closer to 100kt, and $5 of electricity used in half an hour might equate to around 50nm straight line distance.

      It’s pretty impressive for a plane roughly equivalent in size to a 30-seat turboprop airliner like the EMB 120

        That seems like really bad efficiency, or really expensive power. I used to have a Nissan Leaf that would do over 5 miles to the kW. Even with rather substantial battery degradation, I could get 80 miles to a charge, and a full charge would run me about $1.25 at the local utility rates.

        My 1975 was tuned for distance. When I drove it from Key Largo to Seattle, it did 35mpg average over the 3500 miles I drove. That car was lost in an accident, sadly.

        25 miles per gallon. 30 minutes would be 12.5 miles on half a gallon.

        My current one does about 25-30 mpg. It weighs 1950 pounds. So, yes. It can comfortably do half an hour on one gallon or so and have fuel left to get me to a refill.

        They have flat 4 two liter VW engines. Extremely efficient if tuned correctly. One top of that, there is a direct 1 to 1 drop-in electric kit for these. When my current engine dies, I have an electric kit I’ll put into it to make it an 914E.

          Let me spell it out for you.

          The achievement being reported is that the plane performed a 30 minute flight. The implied details being that it took off, flew around in circles, and landed again at the same air port.

          The distance the plane traveled is not the achievement and it’s not relevant.

            If humans can hang glide I don’t see why we couldn’t use those aerodynamic principles to try to glide a car hooked up to glider wings. It’s a real engineering challenge, but I feel like it would be possible to get some distance in a scenario where a car uses its wheels to go fast, drives off a cliff, deploys some kind of glider wings (or drive with the glider wings timed out to where the car gets to the cliff edge right at the point where the wings plus updraft provide enough lift) to get the vehicle to glide a substantial distance.

            Seems horribly dangerous but not impossible.

        $10 an hour still seems really good though right? I’m not sure how much Airlines pay currently for fuel though.

        Only article I could find was this: https://flyinginsight.com/2026/02/14/how-much-does-it-cost-to-fuel-an-airplane/

        On average, a 737 or A320 consumes between 2,500 and 3,000 litres of fuel per hour

        Take a typical two-hour flight, such as Amsterdam to Barcelona. The total fuel burn would be approximately 5,500 litres. At a reference price of $0.59 per litre, that translates to around $3,200 in fuel costs.

        So that’s $10 an hour down from $1600 an hour? Seems decent.

          The X1 demonstrator is more comparable in weight and power to an EMB 120 Brasilia, a 30-seat turboprop. Forum chatter seems to indicate those burn around 1000 lbs per hour, or $335/hr in fuel using the $0.59/liter price you mentioned.

          Dropping down to $10 is still pretty decent lol

    I can understand a hybrid train because of certain sections of track electrification issues and the fact that diesel electric is how even trains that run entirely on diesel operate so you’re essentially just toting around a generator to operate your already electric engine. I understand hybrid cars with regenerative braking and range extension. I don’t really understand hybrid planes.

    Like I can imagine electric is more efficient for takeoff because electric engines produce more initial power generally than what fossil can match per engine size(a big part of both hybrid trains and cars both using batteries for initial acceleration) and then you cruise with jet fuel. I’m just having a hard time imagining it is worth it from a defossil fuel perspective or from a straight efficiency perspective.

        What do you mean? I favor synthetic aviation fuel derived from hydrolysis which is very lossy on energy and would largely kill most current air routes in favor of trains. I think a 40x price increase on fuel is likely, but the actual implementation is proven since it’s essentially plug and play with existing infrastructure. I think the best way to make up for the subsequent loss of profitable air routes is electrified rail. This tech isn’t for getting off oil though, it’s for reducing use at best and if it actually does improve efficiency it would be used along with synthetic fuel.

      Combustion engines have maximum fuel efficiency at a specific RPM. A Hybrid has the advantage that you can run that engine at maximum efficiency 100% of the time and using the generated electrical energy to generate motion. The gains by being able to keep the ICE at peak efficiency are more than the loss you take from the conversion. That’s the same principle as in hybrid cars - look up Technology Connections video where he analyzes the behavior of his hybrid car. It is for sure preferable to than just the ICE directly, losing a lot of efficiency and therefor fuel because of differences in needed power output. Combining this into a plugin-hybrid makes - as you said - the takeoff use no or just the default amount of jet fuel at all.

      This will not eliminate the need for jet fuel, but even a reduction is preferable to the status quo. Until we get batteries that are light enough while keeping energy density at least as high as now (preferably higher), purely electric long-range flight is not an option that’s available.

        Some military tanks are going hybrid, too, despite not really being able to move very far on the electric battery. It’s still worth it for idling and running the on-board systems without actually running the fossil-fuel-burning engine, though, and is potentially a stepping stone towards greater improvements in the electric drivetrain for quieter and more energy efficient movement.

        I don’t think you’ll ever get there for flight personally. Just need to accept synthetic aviation fuel as the only real option for energy density (both volume and weight) and accept certain modalities being absolutely priced out of air transport.

            You want to know why I don’t believe we’ll get batteries with enough energy density for sustained long haul flight? I was responding to their last sentence. Ya know, acknowledging that batteries more dense than hydrocarbons isn’t really on the radar so for that aspect of things synthetic aviation fuel is pretty much what you gotta accept to go for zero carbon. I had already agreed with them that it’s more efficient in takeoff in my initial post. They just expanded on why. I frankly am perplexed at what you think I’m dismissing since we largely agree.

              There’s a whole world of use cases between no electric and full electric. Take off and landing is one of the profiles where electrification might be useful, if not for efficiency then for reducing noise and pollution levels around airports.

              To be fair, you probably don’t need to achieve the same energy density as hydrocarbons for the vast majority of flights. Yeah, non stop flights from canberra to stockholm or similar distances will probably (at least in our lifetime) always depend on high density fuel. But I can definitely see a near future where 100% of flights on the same continent can be run 100% electric. The energy conversion to electricity is most efficient in power plants and solar, so making sure that as many flights as possible are powered by those sources is for sure something that is preferable to anything we are doing today.

              Also, those batteries - after having outlived their usefulness for aviation because of capacity loss - have still a long live in front of them as energy storage for the energy net itself, where a loss of 20% capacity isn’t a dealbreaker. Since the largest issue nowadays isn’t generation of power, but storage of the same for covering nights, building high capacity batteries is a good thing regardless of initial usage.

              Edit: WHY the fuck aren’t airports already plastered full of solar cells?

                I haven’t really seen proposals for planes that are full electric beyond just toys for rich people to do short hops but you might be right that battery planes might make sense with future battery tech. I just don’t see anything justifying it right now.

                On the subject of energy efficiency though, you’re absolutely right. Synthetic aviation fuel is an order of magnitude more expensive than batteries.

                  I wonder if short hops in electric propeller planes are gonna take over everything in a few years. Like it will be the cheapest option for any trip under about 800 miles. Cheaper than driving, even in an electric car. A few Canadian companies are already doing this with seaplanes, where most of the trips are under 30 minutes anyway.

                  This tech is mature, in the US we’re just waiting on the FAA to certify it.

    I really hope this will catch on for once, it could be a great solution for all those people who insist they have to do domestic flights… (in countries like Germany which aren’t that big comparatively speaking)

      People who insist on domestic flights in Germany are really critiquing the train network which is vast, but way to slow and the on time performance is terrible. If they would fix the trains there would be much less call for flights.

      Better than the US is not an endorsement.

      Yeah unfortunately this is only viable for extremely short flights 100-200 miles as the article says. Batteries are just to heavy and planes needs too much power for anything more.

      These would be the perfect private jet for the ultra rich who take a jet to work a few minutes away, or to go shopping, but for commercial flights they’re basically not an option until we have a huge breakthrough in battery tech. We need the mythical “coming next year” for the last 20 years “solid state batteries”.

        As I said in another comment, this is a step towards making a more efficient hybrid plane for trips under 500 miles, of which about 4 million are made per year in the U.S. alone. Having enough battery power to take off efficiently makes those trips a lot more economical. On longer flights, fuel for takeoff is a lot smaller portion of the overall costs and doesn’t matter as much. Except for all the fossil fuel burned, of course.

        It looks great for small commercial flights between islands and such, even just for urgent freight, fuel has more complicated logistics and avgas has lead in it.

        Yeah that’s it. It’s not a matter of “catching on”, it’s a matter of better battery tech emerging which is more affordable.

        Personally I think high speed rail is a better bet. All the tech already exists and the weight of the batteries is less problematic.

        IIRC take off and landing is using a huge portion of the fuel needed in regular planes. If you can use this new technology to do those manoeuvres, it would also be a big win for general flights.
