All of you are woefully short-sighted, inept and dangerously pessemistic if you cannot even imagine answers to all these challenges: just as 20 years ago fools such as yourselves could not have foreseen battery energy density improving so rapidly and so dramatically as to give us today's ultra-high performance cars with ranges of 500 and 600 miles (Tesla's Semi truck has acceleration three times what today's semi trucks can give, with 500 miles range... they are already being used for commercial purposes; and the Tesla Roadster with 0-60 mph of 2.1 seconds, 620 mile range, and 250 mph top speed). Yes, you are DANGEROUS, because lugheads such as yourself have the effect of group-think that impedes the continuum of progress. You cannot see anything being better than it is today... but if you make the minimal effort you would find that companies such as Airbus already have smaller viable airworthy EVs-- electric systems are far more reliable due to extreme simplicity and minimal motor size. As in the video where you see multiple tiny motors across a wing, each motor can have an entirely separate system of batteries and electronics. Such redundancy provides reliability and low cost of operation far beyond anything achievable by fueled aircraft. There are constant new developments and breakthroughs: they recently discovered, for instance, that a bizarre quality of graphene allows electrons to flow with extreme efficiency across their plane when oriented at an angle of 1.1 degrees: they do not understand-- nor know yet-- how to make practical use of this unpredictable curiosity, but it took decades before we started to see tiny lasers used ubiquitously in all manner of personal, industrial, information and security systems. Keep your distance, any of you myopic imbeciles. It took a single individual, Elon Musk, to show, after more than a half-century of "common knowledge" to demonstrate that, no, it is not impossible to boost a satellite into orbit with a rocket, and then save $35 million or so each time you direct the rocket to come back and land, to be reused multiple times. SpaceX has done exactly that 50 times or so already, reducing the cost of space industry by two orders of magnitude. Stop trying to tell everyone what is impossible... you humiliate yourselves, and incur the wrath of those with more good sense.

[@teardowndan5364]

@@artoruvidal2793 Not really, a jet engine is only a glorified air compressor, there isn't a whole lot that can go wrong with them already. The real challenge with jet engines is getting the fluid dynamics right. Even if you replace everything from the combustor down with an electric motor, you still need to do maintenance on the fan stages and bearings. Also, if you want to match a 747 engine's 45MW/4000kg, you would need to scale the highest power-to-weight electric motor I could find (200kw/20kg) to ~4500kg... so you start with a 500kg handicap before attaching fan blades to the motor shaft, adding bearings with their oil pumps, something to mount the motor-fan assembly to the rest of the plane, the motor's VFD unit which ain't going to be trivial at 45MW, a cooling system for the VFD, likely a cooling system for the batteries too, etc. I wouldn't expect electric flight to make it much beyond light aircrafts.

How does it take 15mins to explain energy density isn't high enough in batteries yet?

[@perpetuant5452]

I'm looking forward to the free roads to be honest.

[@jptrainor]

A 747 holds about 200,000 litres of fuel. There is 10 kWh of energy per litre. The gas turbine engines on an aircraft are about 40% efficient. So that's 200,000*10*0.4 = 800,000 kWh of equivalent stored electrical energy. A Tesla 3 battery is 75 kWh. So the 747 would require about 11,000 Tesla three batteries. A Telsa 3 battery weighs about 1000 lb. So that's 11 million lbs of batteries to power the 747. A 747 has maximum take off weight of 910,000 lb, or about 1 million pounds. So we're an order of magnitude away in terms of weight, without considering cargo, passengers, or the weight of the plane's structure. That also doesn't consider the cabin heating load, which is substantial. Assuming that one could make an engine that even had the thrust necessary to fly the plane. A Tesla level 3 super charger's sustained charge rate is about 150 kW. So to charge the 747 batteries in a reasonable amount of time (under and hour) we'd need 11,000 * 150 kW = 1650000 kW = 1.6 GW of power. So expect to build a dedicated, very large, power generation plant, at every airport. Something on the order of two or three 5 GW nuclear power stations would be necessary at a large airport. A small airport might get away with one nuclear power plant or about 1000-2000 large wind turbines or 1000-2000 square kilometres of solar. And God help the firefighters trying to contain an out of control electrical fire, or a short circuit, in a fully charged 800,000 kWh battery, and the passengers trying to escape it. Imagine the scenarios.

[@billdale1]

@@SuperJohn12354 OMG! What utter tripe! Where do I start? No, all those car companies do NOTTT have hydrogen cars ready to go! On the contrary! BMW had a hydrogen version of their 7 series more than 10 years ago! Nobody wanted it! Have you EVER seen one on the street?! Honda and Toyota were always talking big about their Clarity and Mirai boondoggles... but what happened with them? You can't fool anyone into buying a car that runs on peanut butter, if there are no peanut butter supply stations to accommodate you. There is no good way to calculate all the EV charging stations all over the country, but when you count all of the ones at factories for their employees to use for free as a perk, or the ones in parking garages, theaters, restaurants, museums, etc., it is safely into the high tens of thousands. How many hydrogen stations? 69, as of the last count. And how many HFC cars? Google it yourself: the number actually DECREASED last year, because nobody wanted one! About 8,000 in the whole country, less than the number of Teslas made in a month. Contrast that with EVs: on March 31, 2016, Elon Musk announced he was ready to take orders for the Model 3; he said it would require a $1K deposit. He was only expecting a couple of thousand orders. What a surprise: within 24 hours, he had ~ 186,000 orders with deposits. Within one month, that number had swelled to close to a half-million. It took them years to catch up with the backlog... their Gigafactory in Sparks NV, is the largest building by footprint in the US, and 2nd by volume. All it produces is batteries for them. They took less than a year to build their next factory, 212 acres in size, and were producing cars in less than a year. Where are all the HFC stations? It's simple. No one wants a HFC car if there is nowhere to fuel it, and no one wants to build a fueling station if there is no one to sell the fuel to-- a classic Catch 22. Why not build them? That's even simpler: a fueling station costs between 1 and 2 million dollars. Do the math: to install, say, 30,000 of them, which is actually just barely adequate, that would set you back something like half a TRILLION dollars... who would risk installing them, if there was no guarantee of a market, if they considered the facts below? Who would even have that much cash? Anybody that DID have that much, would be smart enough and savvy enough to know it made no sense to risk it all on anything such as a distant also-ran to EVs. Unlike charging stations, which cost as little as $800. bucks including installation-- in many areas, the city or the utility will install it for free, and maybe even kick in the hardware, too. That's how it works here in L.A., and many other places across the planet... cities are eager to get everyone to drive EVs, because it's the cheapest and easiest way to reduce pollution, health care due to asthma attacks, emphysema, heart attacks, etc. Back to those woeful HFC cars: why would car companies be so eager to sell them? Again, simple: it was like having an umbilical cord attached to their customers. Once a driver has one, it's a hot potato: they can't sell it... it is only good as scrap metal... so all they can do is drive it, and pay dearly for the fuel, which they can only get from the dealer, or someone connected to them. EVs might not need anything from the dealer or manufacturer for years except for piddly stuff like tire rotations and windshield wipers; all of that is the main profit for car companies: they make more profit off of parts, oil changes, tune-ups, tranny service, radiator flushes, etc., than selling the car. As for HFC cars, there is less maintenance (at first!), and they give the hydrogen fuel to the customer free for the first year or so... but once the honeymoon is over and they have to start paying for things, a HFC car will break their backs: presently, the fuel is several times as much as gasoline-- $15. per gallon, give or take, and the cost gets kinda fuzzy since, for instance, you can't just fill your car up on Monday, park it for days, and expect a full tank to be there when you need it for the weekend: hydrogen gas needs to be kept at hundreds of degrees below zero just to keep all of it from boiling away. (You said something about using sunlight to make the hydrogen... that is an incredibly inefficient way to make it, called hydrolysis. But the alternative-- called hydrogen reforming-- is no better than using gasoline, as it produces just as much pollution. It's a no-win situation. Even under ideal conditions, hydrogen atoms are the smallest particles on the periodic table of elements, so there is literally nothing than can hold it-- even in a solid steel container, it will eventually escape from the most infinitesimally small cracks and valve clearances... it will seep right through solid tanks as if they were just sieves. Wanna park that lovely FCV right next to the gas water heater, in your garage... the one with the pilot light?? Do you still want your house to be there in the morning? Are you always going to know if there is a cigarette smoker, or other source of ignition nearby? Would that weigh too heavily on your mind to be worth the stress and anxiety? Hydrogen can make many materials brittle... what exotic internal parts will you have to replace in a few years, or chance having a catastrophic failure? So many more problems... too many to count... have you ever seen the Hindenburg Zeppelin crash of 1937, in NJ? (Search for it.) Before that happened, people loved the whole idea of riding in a quiet balloon floating though the sky... afterward, everyone was horrified and unwilling to take the chance. Immediately, hydrogen was a curse. That was more than 80 years ago... people forget; people die. But what happens when Soccer Mom with a van full of kiddies is at the fueling station when a semi truck loses its brakes, and plows into them, and they suddenly become the first story on the nightly news-- worldwide? Will ANYONE be convinced to get into a FCV again? The entire fuel cell² market will die overnight. So much of what is wrong with FCVs, has much more to do with what is right about EVs: look at the stats on how many EVs have been responsible for fires, and you will see they are per capita much safer than ICE cars, and infinitely less worrisome than FCV cars. They have no fuel tanks to explode if rear ended. All the heaviest components in an EV are way down between the wheels, giving it a low center of gravity, which means excellent resistance to roll-overs, and they will corner like a Formula One racer. There is so much more... do you really need to know? Hydrogen is DEAD, and always has been... the hucksters trying to sell them just never told you that.

6:31: So, they want to try to decrease CO2 emissions by making the planes slightly more efficient (which wont happen with the hybrid systems that they're proposing) and then make regional air travel a more common way to travel?

My thoughts and concern with electric planes as it is with cars is, what happens when these electric cars and planes are obsolete and replaced? Are these batteries recyclable? Honestly, we don't even know if the car batteries are and creating a mass of these in the future could create worse pollution than what we have by replacing one danger to another type of monster.
