Right now yes. But those planes are running on five year old technology currently. Not even close to state of the art. That Pipistrel plane has a fairly modest wh/kg ratio. Not even close to state of the art. Doubling or tripling its range is very feasible. 500wh/kg is on the market right now but not in anything that has been certified yet. That just takes time. By the time that happens, the state of the art will have moved on to 750/wh/kg or even kw/kg type ranges. So, mostly this is going to take a lot of people by surprise because they aren't following the battery market. But it's basically going to happen on a fairly predictable schedule. In ten years or so, there will be lots of short haul commercial flight that is battery electric. Long haul is going to take a bit longer but it will come as well.

@@JillesvanGurp The aviation industry is extremely slow to make significant changes, especially to develop new planes, mostly because of extremely strict regulations, but also very low production numbers, compared to for example cars. The Cessna 172 is the worlds most produced aircraft, all categories, ever, and some 44,000 units had been produced a few years ago, since 1955, and it is still in production, so now maybe around 50,000 in total, since 1955. That's less than a thousand units per year on average, even if you discount the few years it wasn't produced. The batteries can be changed, easily, whenever there's better batteries available, and the Velis Electro doesn't use the exact same batteries as when it was first developed, which was mentioned in the video. High energy density is great, but there are other aspects that are important, as safety, longevity and charge/discharge rate. The amprius 500 Wh/kg battery has a life expectancy of 150 cycles, and max continuous charge and discharge rate of 0.1C, meaning, you can't use or charge more than 10% of the capacity per hour. That means for the Velis Electro, to be able to use say 25 kW continuously, they would need to have 250 kWh of capacity, at 500 Wh/kg, that's 500 kg. 500 kg is more than that plane weighs, including currently used batteries, and having 500 kg battery cells, plus packaging, would make the payload capacity negative. In other words, a max 0.1C charge/discharge rate means a plane would have to be designed for at least 10 hours of flight for those batteries to be meaningful, that's ballpark 3 times more range per kg of batteries as the Velis Electro. A plane would have to be huge for a given payload to achieve that, and for commercial use 10 hour charge time would require swapping the batteries instead of charging in the planes, and 2 sets of ultra expensive packs for each plane in operation, one in use and one charging. Batteries are getting better, but on average per year, it's a few percent overall improvement that reach the market, except when some some important factors are sacrificed to reach some absurd specific capability. Super low power density, 120 cycles, and probably absurd cost on top of that, and questionable safety isn't great for aircraft, even with 500 Wh/kg energy density on cell level.

There's a definite elegance in having these small electric general aviation planes omit the usual level 2 charger and charge exclusively from DC fast charging. No point in carrying around all that extra weight, especially because these only fly between a small number of purpose-built locations (runways) where installing the charging infrastructure is trivial.

I’m thinking that solid state will be the future of ultra lights like the Pipistrel. I owned a Jabiru J200 for 15 years and the idea of almost no servicing, no mags and no Avgas is quite appealing. 3300 Jabiru engine was a bugger to get going on really cold days and the battery was tiny. Imagine just a throttle and maybe auto prop pitch controller. I must say I did prefer the control stick in the middle next to the pilots right hand rather than between the legs. Made no difference to control but made getting in and out the craft a lot easier.

Super cool electric aviation! Also like Imogen alluded to we're starting to see rhe real world feedback that most don't have a clue of. The example here is electric cars bringing battery costs down while increasing energy density and also second life batteries used at end of a single phase line. Zero grid retrofit. I call BS on those that say it's too expensive to update the grid to make everything electric... Sabine Hossenfelder and every grid operator who see $$$ from a centralised electricity generation and expensive upgrade projects.

It should be pointed out that electric flight (like electric cars) is NOT new. In October 1973 a converted glider flew for 9 minutes powered by Nickel-Cadmium (NiCad) batteries. This was the first manned electric aircraft to fly under it's own power. You may not be impressed with that, but it's an electric flight moment equivalent to the Wright Brothers first flight. Just think, it's been 51 years since this electric plane took it's first short flight. Within 50 years of the Wright Brothers taking off Boeing were flying the 377 Stratocruiser Airliner that could carry 100 passengers. That is a marker of how much progress could be made with electric flight within one generation.

Thank you for that big picture summary in the middle of the clip Imogen, it really helped 👍

If there's a hangar to put solar panels on, providing the amount of energy needed to charge a few small light electric planes shouldn't have to be an issue. Especially for planes that typically requires daylight to be flown, and are mostly flown recreationally, meaning the correlation between generation of solar power and use of power for charging should be about as strong as for air conditioning. Some batteries are still required unless there's a grid connection that can handle the difference in generation and use at any given moment, but it shouldn't be too difficult to generate much more than the overall amount of energy required onsite in most cases.

Done quite a few military exercises at Dunkeswell, great to see electric planes there as well

That Allye SES unit looks small enough to be truck mounted and serve as a mobile charger.

With regard to the charging infrastructure for aviation, it would seem like a good idea to use the apron of the airfield to erect a solar array to charge the battery banks for the chargers .

I think electric planes will be handy for short hop flights, especially if airports are equipped with chargers to support them. I'm thinking places with a lot of renewables - solar or wind like the Orkneys where electric would mean not having to ship fuel to these places, or only using it as a last resort. I don't think electric is viable for normal passenger travel yet where weight and range would be limiting factors until higher density batteries start appearing.

this is excellent, very good. the range will get better as battery technology provides larger energy density.

An ultralight is a great proof of concept but for some more serious range the battery has to be a large fraction of the takeoff weight, like 50-60%, not 25%. Hope to see some slightly bigger models soon. 10 min contingency really forces you to stay close to the airport, usually the contingency has to be 45 min but then the planned flight time would be 15 min...

I think the Pipistrel is like the early Nissan Leaf - about the same range and charge rates. So we can expect to see similar progress in range and charging rates compared to cars as time passes. With the Pipestrel, if the next student is ready for their flying lesson, you don't really want the aircraft idle for an hour. Does the current Pipistrel still have the swappable battery packs? If so, can those chargers work with the battery packs off the aircraft? And one important figure they didn't give us, how many pence per KWh are they charging for aircraft to use those chargers?

Where is the nearest flying school to Lincolnshire which uses electric aeroplanes? I'm interested in seeing one and buying a demonstration flight in it. Thanks.

I saw some large roof area there with no solar! :-)

Flexible lightweight solar panels on available surface area of a wing/aerofoil should be the only way to go for augmenting range. Then ofc retractable landing gear, and more attention to aero overall could make that existing plane alot more practical.

How many electric aircraft are currently registered in the UK? And in Europe? Great to see additional electric aircraft are working towards certification.

These small aerodromes would be perfect for larger sized solar arrays, either ground or rooftop mounted, since there's usually plenty of unused available space, the pairing of which with large battery storage should enable the adoption of small electric aircraft to move quicker and make 'fueling up' so much cheaper than that of the current liquid aviation fuels.

Crashworthy, thermal runaway inhibiting, HIRF/EMI tolerant. One battery pack is located in the nose of the airplane and the second behind the cabin. This ensures redundancy of the power source: in case of battery failure, the malfunctioning battery would get automatically disconnected from the system. A single battery is capable of standalone operation and has enough power capability to support climbing and continuation of flight."

Could this be at the Farnborough show?

Looking at these electric planes they are very similar to ICE powered planes. I wonder if there are any benefits to changing that design so that battery can be placed in a different place or structured differently. Same like Tesla did in their designs

It would appear that landing is actually harder than with the ICE engine. The pilot appeared to be constantly having to adjust the throttle setting all the way through the touchdown. This would make sense if the propeller has "engine braking/battery recharging". It wouldn't be as simple is simply pulling the power off on your Cessna, letting the prop "idle" and then gliding down for your last 10-20 feet. Instead, it looked like the pilot had to worry about getting the throttle setting "just right" all the way down - as just pulling power fully off looked like it was creating actual drag as from an electric motor trying to harvest power back into the battery. Am I wrong?

Yea, not sure what he was doing. The original plane this was based on is a powered glider. Should be able to cut power soon as runway is made and glide down like a normal light aircraft. Maybe he was floating on purpose to taxi off the end. Or maybe he really wanted a smooth landing for the camera.

Normal for light aircraft. The slight changes in the wind have a larger effect on an aircraft that is both flying quite slow, and is quite light. That means the pilot has to adjust power constantly. Happens in an ICE light aircraft too.

I wouldn't be surprised if he was trying to touch down at a specific spot for the camera. I've be very surprised if the designers had made the plane harder than necessary to fly, and regen braking is a bit pointless on a plane because you don't change speed much.

An earlier version called the Alpha, did have a special prop that allowed regenerative descent which recovered 13% of the energy in circuit flying. Complexity and homologation difficulties made this option not possible on the commercial Velis version.

Skydiving or gliding should be in a way that it spins the propeller and charges like regenerative braking.

love the pants.

Generally there is a lot of empty space at airports. A solar array to charge the battery should be possible.

wonder how long until they are in the states..

The FAA has just granted Textron eAviation’s Pipistrel an exemption from the light sport aircraft (LSA) regulations, allowing the company’s Velis Electro electric-powered airplane to operate under LSA regulations in the U.S. This means that flight training schools and individual pilots can now fly the Velis Electro without restrictions.

@@waynerussell6401 now I wonder when one will be available at my local flight school... I've been asking and the personnel act like it's way over budget.

For commercial aviation, regardless of the energy source/storage onboard the aircraft, I imagine some sort of maglev rail gun being used to handle taxi and acceleration to takeoff speed. Based on the estimates I have seen, this could reduce the energy storage requirement onboard the plane by 5-10%. This would both make battery electric and fuel cell aircraft more broadly viable and also would represent a meaningful reduction in emissions and/or production requirement for hydrocarbon fueled aircraft. Would require some standards and engineering, but it seems like details and not breakthrough technology.

Well said! And what about the advances in the in wheel motor space? Now they can be 10-20+hp per kg and with built in braking systems? Maybe ev planes could use these to taxi&accelerate to takeoff speeds, but also regen massively upon landing? 🤔

By the time you have changed airplane design to enable a rail gun launch, besides all the risks and huge costs involved, you're looking at 10+ years development time (design + testing + approval + implementation). By that time battery density per kg has increased by more than that improvement. Also don't forget that there will be a weight increase on the airplane to enable a safe launch system installed, increasing energy usage. There's also a lot more maintenance required for such a system, there's more risk involved in crosswind and with possible decoupling issues and the amount of airports will be hugely limited. I think money is much better spent in improving the battery technology quicker.

So why aren't they putting solar over all the hangers? All those hangers will have a lot of roof space to put some massive solar arrays.

I think some commercial airports already do, although the electricity generated is just used to help power the airport building, not the actual airplanes. On the grassy area between runways, I'm not sure if that would be legal or safe. They have to account for the fact that an errant plane might veer off the runway and smash right into them, which is why this area has no trees in it.

What’s the price point for these planes?

Very cute

Aren’t airfields idea for Solar & battery storage. Lot of roof space on plane garages!!! , as long as you can limit the reflectivity of the panels

Panels with less reflectivity would also glean more energy from diffuse sources, too.

I'm pretty sure there's enough space at airfields to stick some solar panels to charge the charger

It's a GBT connector. It's likely that aircraft will be moving to the CCS standard instead.

Should we rethink whether we need to have long haul flights, nothing wrong with a few shorter flights, a guess on distances, could we fly from London to Turkey to India to Western Australia then to Sydney, I'd rather this than long haul, might have to stop at some small islands in the Pacific Ocean if you want to get across to the Americas etc Should be possible to have battery swapping at appropriate locations for a quick recharge, could be a slower less energy intensive to charge the batteries this way. I believe this will be the way for all transport, we can do this now if we want to.

Interesting but I’d like an update in a year 🙏
