Electric aviation is on the horizon as global demand for environmentally friendly transport grows. Currently, aviation contributes significantly to CO2 emissions, making it a prime target for green innovations. The rise of electric cars has catalyzed advancements in lithium-ion batteries, potentially paving the way for electric aircraft. Although today's batteries fall short in energy density compared to jet fuel, ongoing innovations bring hope. Companies like Pipistrel and Harbour Air have already showcased electric planes, primarily for training purposes. Notably, hybrids are emerging as an interim solution, offering a blend of traditional fuel and electric power. With the anticipated boom in urban air mobility, the aviation industry could witness massive production scales akin to the automotive sector. Challenges like rigorous safety regulations and battery efficiency remain, but the evolution of electric flight is undeniable. Key terms: electric aviation, CO2 emissions, lithium-ion batteries, Pipistrel, Harbour Air, hybrid aircraft, urban air mobility.

I completely missed the answer to the question about "why electric planes are designed to fail?"

@Dwaynesaviation 6 месяцев назад

Battery

@grahamstevenson1740 4 месяца назад

I think he meant destined. Simpy, batteries havent anywhere close to the energy density of petroleum fuels. In short, they cant fly very long/far. The very longest endurance of a very lighweight design, the Pipistrel in an hour. Conversions can fly for perhaps 30 minutes with minimal load carrying capacity, E-VTOLs perhaps 10-15 minutes.

@elstevobevo 7 месяцев назад

Burt Rutan could have designed better planes 50 years ago. We need to solve the battery issue, not design new planes. The planes will come automatically. Right now the biggest problem with electric aviation is everyone designing useless prototypes when they could be putting that energy and cash into r&d. Think of all the pollution of manufacture, wasted labor, capital, that goes into these things.

@PistonAvatarGuy 5 месяцев назад

R&D should be going into modern gasoline engines for light aircraft.

@bobfg3130 4 месяца назад

@@PistonAvatarGuy Why? So the money could be wasted? Pal, the US has 12 years of oil reserves left at current extraction rate. In 12 years you will be importing ALL THE FUEL. No point in developing engines that are useless. Either you develop batteries or you can develop fuel cells for hydrogen and power electric engines like that.

@bobfg3130 4 месяца назад

Worth saying that everyone developing new aircraft means "pollution of manufacture", wasted labour, capital. It's how things have ALWAYS been. Learn some English. Also, it's clear you haven't figured out how manufacturing works: THE PRODUCT HAS TO BE DEVELOPED. Basically NOTHING COMES AUTOMATICALLY. Those planes SHALL HAVE TO BE DEVELOPED and if they have a design finished, they have an edge.

The Harbour Air conversion of a seaplane carries ZERO passengers. Also only around 30 minutes total flight time. It will however take HOURS to recharge. How ridiculous. NO USE AT ALL.

@grahamstevenson1740 4 месяца назад

There are ZERO commercial electric planes. The Pipistrel can only carry 2 persons for an hour at the very most at rather low speed in an unheated unpressurised cabin; THAT is the best batteries can manage.

@eddies6977 4 месяца назад

The biggest problem with flying cars is people. They can barely handle 2D traffic, let alone 3D. We'll need a quantum computer on a 7G network to keep them apart and running.

@bobfg3130 4 месяца назад

Another option could be the use of Hydrogen. Either a Hydrogen turbojet engine or an electric engine powered by a fuel cell. Also, those "sky taxis" will not exist. Why? It will cost too much and will pollute too much. It will not be safe either. Think about a traffic jam that's in the air. You also need MORE SPACE in the air with a helicopter or another type of vertical take off and landing aicraft. Also, skyports? Ever heard of airports? It's either that or a helipad. Don't try to make stuff up. Hybrid aircraft are an interesting option.

@gpaull2 5 месяцев назад

Electric cars have not supercharged battery development. There has been very little progress since the commercial debut of the lipo several decades ago. Elon has over promised but under delivered…like all of his business ventures.

@bobfg3130 4 месяца назад

Nobody's talking about Elon unless they're a Musk fan. There's been progress in batteries. Don't lie about it.

@@bobfg3130 NO. Batteries are still very low energy density compared to fuels like gasoline/diesel/jet fuel. About 1/'40 th the energy. BIG problem.

Whoever this is has no clew how many moving parts an electric motor has clearly! Less than a jet engine, but definitely not just one!

@gpaull2 5 месяцев назад

Hybrid cars are less efficient on the highway than their ice counterparts because of the extra battery weight. This is even more pronounced in aircraft where weight is more detrimental and there isn’t much stop and go traffic.

@RichardLewisCaldwell 4 месяца назад

That's totally dependent on design. A hybrid with a 30HP engine, a 300HP motor, a 10 mile battery pack and a 5 gallon tank will blow the doors off a 330HP ICE vehicle because of the motor's torque. It will get far better mileage because the 30HP engine is the "proper" size for cruising at speed. It will be lighter than and have more range than an EV (NOTE: a range extending engine MUST be started at the beginning of each long trip, allowing for far more range and far less stress on a far smaller battery.) And extending the range beyond a typical ICE vehicle is cheap and light because engines are far more efficient when operated at 80% load, something typical in the above-described system but rarely happens in a regular ICE, so an additional few gallons of fuel will go a long way. But you're right. Current hybrids suck, compared to what they should be.

@bobfg3130 4 месяца назад

No, hybrid cars ARE NOT less efficient compared to their internal combustion engine counterparts. Stop lying. They are MORE efficient that their internal combustion engine counterparts. The gas mileage shows that.

@bobfg3130 4 месяца назад

@@RichardLewisCaldwell No, hybrid cars are more efficient than ICE cars. Could they be better? Yes. Still, they already surpassed the internal combustion engine cars. Don't lie about it. The gas mileage is showing that.

@grahamstevenson1740 4 месяца назад

Untrue. Hybrid cars get better mileage than ICE. They dont require such large batteries as full BEVs, so the weight isnt a significant issue.

@tinmisuun 7 месяцев назад

Electric planes in the Arctic will not work in the winter. Electricity is produced my diesel fuel and the sun is hardly up during the day. Wind produced electricity is a fraction of what diesel produces right now. Also a lot of planes are stored outside and that is bad for lithium batteries in sub zero temperatures.

@tinmisuun 7 месяцев назад

A lot of hangars would have to be built and those are fueled by diesel to keep those lithium batteries from freezing.

@bobfg3130 4 месяца назад

That means there won't be too many planes soon. Diesel will become too expensive to afford. It's time Alaska switches to wind power.

@PistonAvatarGuy 4 месяца назад

@@bobfg3130 Mountains tend to block wind, Alaska is quite mountainous. Wind power alone also can't power a modern civilization, especially a part of one where people's lives are dependent upon heating energy and they would die when the wind stopped blowing.

@tinmisuun 4 месяца назад

Wind does not blow all the time up there. I have spent a lot of time in Alaska. Plus lithium batteries and freezing temps don't get along.

There are 12 Megawatt single wind turbines right now; Dont dismiss wind power. Europe is using a lot of it.

@PistonAvatarGuy 4 месяца назад

So, kill off the majority of the human species so that you can have electric aircraft? That wouldn't work anyway, because there's no use for electric vehicles in war and if most people died, there'd be a lot more oil for whoever remained, so they'd just keep using that. I always knew evil people lacked the ability to think, but it's crazy seeing it demonstrated in this way.
