Two notes: 1. When using kerosine you can fill the tank as required. On a short flight, you tank less fuel, allowing you to take more passengers and cargo. 2. When burning fuel the aircraft gets lighter and more efficient. With batteries, you must carry the same weight during the entire flight. Another thing to note is that the oxygen needed to burn is free with kerosine. You don't have to carry it.

[@matthewbaynham6286]

15 years ago in 2009 the Mitsubishi i-MiEV was released (which was also badge-ed as the Peugeot iOn and Citroen C-Zero). This car had a range of about 100 miles and was super small, but 15 years ago it was the pinnacle of EV technology. Now 15 years later the world of EV's is so extremely different. When you see how much EV's have changed in cars, you can see that the small little aircraft in this video is like the aviation version of the i-MiEV and in 15 years time it'll be a very different world. I'm sure Hydrogen will be used for anything big which goes long distance, but electric aircraft would definitely be suitable for those 100 seater aircraft that hop from one city to the next will be everywhere. This new technology advances very fast, we now have prototype cars from Polestar that can recharge (10-80%) in 10 minutes, and the best cars that are currently in mass production can do are the Kia's which can recharge (10-80%) in 18 minutes, the VW ID.7 isn't far behind with a recharge (10-80%) speed of 25 minutes. Certainly if future aircraft can recharge in 10 minutes then there is no point to swap-able batteries. Currently turn around times for jet aircraft now is about 25 minutes.

The battery of that ultra light weighs maybe 25% of max takeoff weight. A bigger plane where 50% of the weight can be the battery could get a flight time of close to 2 hours, that would start to become really useful.

Flying less is a flight of fantasy that will never happen. Why? Because flying is based more on economics than on environmental considerations. The only way to get people to fly less is to make flying a lot less affordable, and nobody’s going to go for that - not the passengers, not the airlines, and certainly not the governments who decide on the taxes and tariffs to be imposed. Good luck with that approach.

[@shakthianjanananayakkara6528]

Good luck. Tell that to the Indian IT guy, whose parents never imagined getting anywhere near an airplane , just about to take his first flight.

[@FabioCapela]

@@AtulBhatia You can also build more high-speed rail. For short and medium distances high-speed rail is often faster than flying when you take into account how long boarding an airplane takes. And high-speed trains are not only electric, they also use far less energy to transport the same weight across the same distance than an airplane. This is already being seen in China, the country with the most extensive network of high-speed rail by far, where the demand for flights - both passenger and cargo flights - is falling on just about every route that has competing high-speed rail. This, of course, won't replace all flights; longer flights would still be faster than high-speed rail, and for intercontinental flights it might not even be possible to build rail connections. But it would reduce how much people fly by a lot.

You just need proper thermal insulation and management. An electric car with proper insulation and a heat pump for heat management loses about the same range in the freezing cold as a gasoline car. Heck, the first car to drive all the way between North Pole and South Pole (apart from a few boat trips across the ocean) was an electric one because it can still work in the Antarctic environment, which combines such low temperatures and low air pressure that would prevent regular fuel cars from working without large adaptations to their engines. The problem with batteries and cold is when you have no thermal management, in which case you can effectively lose a lot of range.

[@mr.sunmeadow]

@@FabioCapelafun fact: in 1963, Australia brought with them a Volkswagen Beetle to Antarctica with minimal modifications. if i’m not mistaken, the only mods they did were to give it a 12V starter motor, and run it on thin motor oil. i just wanted to add this as a little fun fact, it’s nothing against what you said, it’s just a fun thing to know

[@FabioCapela]

​@@mr.sunmeadow It had more modifications than that, it was fully winterized (which is fair, it was an Australian-manufactured beetle which was never expected to ever handle snow). It also was only used close to the shoreline, where the scientific base is located, and not in the interior of the continent where it would face both even colder temperatures and decreased air pressure due to the altitude (which makes it even harder for combustion engines to work properly). Still, it worked very well in a place where most vehicles fail. Its air-cooled engine (so no radiator fluid to freeze) and simple yet robust mechanic made it one of the best possible cars for use down there at the time, beating many vehicles specifically designed for the cold. Which is ironic given that the Beetle is based on German military transport vehicles designed for the Sahara campaign during WW2.

[@zapfanzapfan]

I’ve seen some demonstration that hemp may be an effective alternative, but global regulations stifle innovation in that area; so whether this is true remains to be seen.

Oversimplified solutions rarely work perfectly. Electric planes need an gasoline or jet APU in order to provide heating and extended range.

[@FutureAIDev2015]

I think it might work for really small scale applications but unless we can increase the power density of battery storage by several orders of magnitude or come up with a new way of storing a lot of power with a very very high power density, it will be nearly impossible to scale up.

[@FabioCapela]

Not orders of magnitude. The most energy dense commercially available battery (as in, ones you can buy in large quantities, not just in the lab anymore) has 500Wh/Kg, and that isn't even a solid state battery; fossil fuels have around 13,000Wh/Kg, of which only about a quarter, or about 3,250Wh/Kg, is useful energy (internal combustion engines waste most of the energy in the fuel). Then you need to take into account that, apart from the battery, everything else related to propulsion in an electric vehicle - including an electric airplane - is lighter. Wires in place of fuel lines, no pumps, much lighter engines, no need for cooling, etc. That further reduces the weight difference. This is still not enough for long range air travel, mind, but if batteries improve their power density by, say, 5x compared with the best ones available right now, that should be enough to cover all current aviation use cases.

[@Cyrribrae]

​@@FabioCapelaagree with most of that. Though, a lot of the weight in EV applications comes because you DO need cooling - and often a lot of it. Especially in an application where you may be going through temperature extremes over the course of a flight, thermal management will be essential.

However, this means that the only obvious utility of battery or hybrid planes would have a better, and better-established competitor... It's all still quite up in the air

[@steveco1800]

Could a hybrid design work somehow? Using traditional fuel for when power's needed but battery power to cruise? Or could it be too heavy?

[@Cyrribrae]

I honestly didn't understand the hybrid argument. If it's in series, then we're trading one inefficiency for another. There are limits to the improvements there. If it's parallel, then you're still dealing with a lot of weight just for the sake of partially improving the problem. Meh to both. Pursue tech like hydrogen where necessary. But find applications where battery will work. That may not be cargo, but there's plenty of aviation that takes place with small groups of people or small alone of cargo over modest distances.

Somebody finally mentioned the hybrid concept I have been talking about for a long time. Granted, I have been exploring idea mentally like getting into superconductors and trying to get those superconductors high temperature enough to be cooled with LNG, which then gets burned in the jet engine part of the hybrid aircraft was well as advanced batteries like LiS possibly tripling the energy density of the battery if a suitable configuration can be found that will last as LiS has not historically been known for longevity. Something else to consider is eFUEL. This is as in synthetically creating fuel with electricity. You keep using the hydrogen example, which has largely been reformed from fossil fuels, so nothing saved, but really eFUEL covers a more broad range such as methane, propane, and even liquid, gasoline like fuels at room pressure and room temperature. You may go well the easiest to do, hydrogen is super expensive to do from the eFUEL route today and if you look into these other fuels, it is even more expensive. Yes. eFUEL is just not that efficient to make. People are always working on more efficient ways to make eFUEL and there have been advances over time. I would venture to say this is where better nuclear reactor designs like coming up with a cost effective to mass produce Thorium Molten Salt reactor should be considered. If you can mass produce this type of reactor, which is inherently safe and needs far less material to be made safe than light water could ever dream of being, I mean we are comparing a modern fighter jet like the F-22 to a WWI era Sopwith Camel kind of deal here, we may be able to produce the electricity reliably and consistently round the clock to make eFUEL cheap. When eFUEL becomes cheap to make, you start looking into denser forms like methane, propane, and even this gasoline like stuff and especially want to try to make something more like kerosene so you can just stuff it into existing jets and call it a day. And for the environmental friendliness of eFUELs? With hydrogen, it just takes up too much space in the airliner, plus it is pretty easy to end up blowing away a whole airport in a mishap and surrounding city with big fires raging with toxic materials burning in the raging inferno, so it is actually pretty hard to justify this. With methane, it still takes up a lot of space, but you start getting into you could stick it into an attic tank in a large airliner as a cryogenic liquid that would normally have the attic space largely unused and then if you can mix it in with cooling superconductors for a hybrid electric plane, maybe it starts making some sort of sense. With propane, this starts getting to be a lot easier to handle as it turns into a liquid with a modest amount of pressure, takes up even less space, gravimetrically is more energetic than standard jet fuel, and at least the last major loss of containment I saw when a "bomb" train derailed, the propane found an ignition source before it could fully boil into a gas and mix with atmospheric oxygen, so it turned into a mostly harmless fireball with one complaint I came across of someone saying when their vehicle got licked by the fireball, their trailer caught fire. But the point is they could be close enough to catch fire without getting killed by a huge blast as there was no big blast. Granted, there was a huge mushroom cloud over the derailed bomb train, but that always happens when you have a lot of heat in one spot. It was just the flame progressed slowly enough to not make a big boom while the big booms are what normally do the most damage. Methane and especially hydrogen are far more prone to more rapidly mixing with atmospheric oxygen and so are far more likely to create a big boom once they find an ignition source. Getting into making eFUEL, you start with splitting water into hydrogen and oxygen. With heavier eFUELs than hydrogen, you get into soaking up CO2. So say you pull the CO2 out of the atmosphere, you just put back what you take out when you burn the fuel. Then a normal product or bi-product of burning the fuel is water. So you put back what you started with and so have a circular cycle, no net emissions.

4:15 - A Hona Civic’s range on a full tank is a little less than twice the range of a Chevy Bolt on a full battery. *_Very unlikely_* we’re talking about a factor of 17.

THIS is why hydrogen, e-fuels, and biofuels need serious investment and shouldn't just be labeled as a "fossil fuel industry scam." Batteries will never have the same energy density as hydrocarbon fuels. They're held back by their fundamental chemistry. And for many applications, energy density plays a major role in overall efficiency.

[@beyondfossil]

You're going to be surprised how dense battery gravimetric and volumetric densities will increase over the next 10 years. Furthermore, electric power systems run in the high 85+% efficiency range far more than even jet turbines and way way more than piston engines. Thus, electric flight does not require the density of liquid fuels though more density is always better. E-fuels *are* a scam. Firstly, they require renewable energy to be considered clean. Worse is that e-fuel usage will still emit the other usual pollutants: like SOx, NOx, CO, nano-particulates, benzene, toluene, xylene and other volatile hydrocarbons that all contribute to nasty smog that congests all of our major cities producing a myriad of long-term health problems. ICE vehicles (including e-fueled ones) are especially bad as they emit that stuff right in our faces in the places where we live, work, and play. Furthermore, after e-fuels are produced, distributed and burned to create power at the wheels, only some 10% of it actually creates kinetic energy and 90% of it is loss. It would have been better to pump that energy onto the grid and charge an EV, electric aircraft or power cities. E-Fuel vehicles could be produced but likely many regions will not allow owners to register their vehicles or have to pay exorbitant registration fees like $10,000USD like they do in major Chinese cities. Clean air rules will only become stricter over the years as they should be to protect people's life-spans and health-spans. Hydrogen is also in the same boat of inefficient production/distribution. But direct hydrogen combustion does not create smog emissions other than potentially some NOx. It would be interesting to see hydrogen packaged in ammonia as part of an aircraft fuel system since ammonia is liquid at -33.6C or 250psi versus hydrogen's cryogenic liquid temperatures and massive 10152psi (700 bar) pressure to get useable energy density out of it.

But still, aviation accounts for only 5% of global emissions, even when 1.89 due to longer stratosphere stay, still is quite small compared to electricity generation CO2 emission, or automobiles. Take the low-hanging fruit first.

[@SchwuppSchwupp]

Don't you think small planes are a low hanging fruit? The example in the video, island hopping planes, seemed like a easy electrification task to me.

[@jamesau4296]

​@@SchwuppSchwupp The problem persists in scale. When talking about Aviation, scale matters. Of course everyone can build a jet, but it takes billions of dollars to certify one that is safe(forget the internet industry or consumer products, aerospace safety is much more rigorous and they have it in place for good reason---you don't want another 737max crash), so overall you need much more demands to recover the development expense

[@SchwuppSchwupp]

@@jamesau4296 sure, the development of a full size jet would be hard to justify, possibly because of physics impossible for now. The stuff in the video is more like a very small plane, a plane of the size a private person can own. These might have a nice business case today.

Interesting that actual 1st Powered Flight was electric in 1883😎! (Like the French Electric Racecar of 1899 did over 45 km/hr!!) Most are stuck on Wright Bros. "1st Petrol Powered CONTROLable flight" (wing warping) which shows how Not the best long term use/design wins, but main success factor to mass produce was cost/ unit delivered...negating a quiet non polluting more relaxing form of transport. Quantity of profit won over comfort or Quality of 'seat-mile' traveled. (Similar to wealthy women preferred Electric 'Buggies' (mostly N.Y. taxi's ) like the Anderson Electric or Baker EV of 1890's+ v.s a smelly, stinky, & Very Noisy Petrol Car of early automobiles!)

[@ndirangugichuki6260]

The reason why we aren't flying in battery powered airplanes is because of two things, weight and possibility of a battery fire.

[@davidmartin6215]

I'm more worried above jet fuel fires & engine fires than modern batteries! As in upthread, weight is now resolved for up to 1000kms with 90% fuel cost savings.

[@dondekeeper2943]

Currently airlines already limiting the battery passengers can bring on board due to risk of explosions and fire hazards. Now they want the passengers to sit on top of the huge explosive and fire hazard? Lmao 🤣🤣🤣

[@davidmartin6215]

Laptop / phone batteries do overheat & explode when charging. LFP & similar batteries for transport do not due to thermal management & more robust chemistry. Avgas is far more explosive than a modern battery.

[@simonloncaric7967]

Swedish electricity is powered by hydro, nuclear and wind. In that order. Still very much low carbon tho

[@mmmcounts]

All conventional planes are capable of flying many thousands of miles, but the overwhelming majority of flights that people actually want to make are less than 500 miles from A to B. This is not great for the airline industry because the limiting factor on the life of a conventional plane has virtually nothing to do with the amount of miles traveled and virtually everything to do with the number of flights- the number of times that it goes up, comes down, and goes through pressurization and depressurization. The likely role of electric flight will be to meet the demands of fairly short flights while introducing a new market for short flight paths that don't yet exist, but a huge amount of these shorter flights will become viable due to the extremely low cost per person per flight and the relatively low seating capacity that is likely to be typical of these electric planes. I'm looking forward to a new trend in travel where people want to travel a few hundred miles, let's say, and doing it by car is not a great option. Going by train may or may not be an option, but trains are slow and kind of expensive at that distance and we are just not going to build tracks that go everywhere. But in the future that I'm thinking of, we usually don't go to an enormous central airport. For shorter trips, we go to a smaller regional airport. If you live in the burbs, it's probably 15 to 20 minutes away. You might drive there and park, you might do a quick ride share, or maybe the train actually does get you to point A at the airport. However you get there, it's a quick process getting from the door to the plane and off the ground. The flight is dirt cheap, there's not a lot of people on board with you, and you cover 2 or 300 miles at an average speed of 150 to 200 miles per hour. That's not as fast as a conventional airplane, but it's much cheaper, you're spending less time in the airport, it's probably much closer to where you live, and the flight itself is short range with low enough demand that the route would not exist without this new technology. So you arrive at another small regional airport about two hours later. It might be less than three hours from your front door to the actual destination that you're going to. It feels a bit like having your own private airplane, except you don't need to spend a lot of money on it. One of the reasons that air flight has gotten less efficient is because there's so many planes and there's so few places that they go to. One of the best things about this path of development is that thousands of small regional airports will get a bump in traffic as they operate in a way that's commercially viable. There is so much airspace that we just are not using, and there's a lot of perfectly good mid sized communities that are somewhat hamstrung by the fact that they're nowhere near a major airport and they have no prospect of having that. If it is the case that a Huge number of these places can be perfectly well connected by a much smaller airport, such that it's easy to get from there to a major airport or any number of other places, this will change the lives of a huge number of people along with their communities and entire regions.

[@AtulBhatia]

1:16 “Aviation makes up for around 3% of global emissions… by 2050 that number is projected to rise to over 8 times that”. That sounds scary, until you realise that the real world aviation emissions are not going to increase; rather, emissions from all other sources will reduce so that aviation takes up a larger piece of the pie. Too, these projections are based on the assumption that aviation’s emissions will stay static, but the fact is that aviation emissions have shown a dramatic decrease over the past few decades, and there’s no reason to believe that they won’t continue to do so in the near future - witness the new breed of engines that offer 15% greater fuel efficiency over the previous generation, and the push to introduce blended wing aircraft with hydrogen fuel in the near future.

[@shintsu01]

the only valid solution is have multiple solutions. Sadly all expensive and not enough willpower to for them. For example if you could use a train instead of an airplane with more room confort and less hassle to get on it will help a lot. Specially if the price is lower. I dont think however this will happen see US for example hardly any investment in quality rail roads and since there is a lot of tax brakes on flying its hard to compete with airplanes.

[@croutiflex953]

Mass aviation is born with the abundance of oil, and it will die with it. Soon. The energy density of batteries is an huge limit that will never be crossed. No matter how many future innovations, we will never have an energy source as dense as kerosene. Of course the agrument can be made for hybrid/smaller planes with a shorter range, but aside for remote places (but no too remote), terrestrial transports like trains will always be more efficient at carrying people and cargo over these distances. Mass aviation is done, and that's a good thing. Get over it. Most people don't get to fly in their lives anyway and they're perfectly fine.
