[@mitchmccarron8337]

SpaceX is smart enough to use pure fossil fuels to achieve full reusability of their rockets & drastically reduce the cost of sending payloads to space. When batteries are depleted of their energy, they still weigh exactly the same. Rockets must lighten their load by burning fuel to reach orbit. Mitch, Australia.

[@sc29607]

You are delusional with this statement. You can’t call a monopoly a norm, at the moment there is no other option than using SpaceX since NASA gave up because of costs and lack of innovation. Surely it’s easier to use an option instead of throwing money into a pit and burn it, especially if the governmental funding got reduced year by year after the space shuttle disasters. So don’t call SpaceX a norm when there is just no alternative at the moment, at least none that would be financially an option to choose from.

One of the biggest issues I see with electrically powered aircraft is the fact that the battery doesn’t get any lighter as it discharges. In a hydrocarbon fueled plane, as the flight progress and fuel is burned off, the aircraft lightens and becomes somewhat more efficient. With batteries, you expend as much energy dragging them along when fully charged as you do when they’ve discharged. And as for commercial travel, turnaround time must be considered - pumping fuel into tanks is a quick operation. With current (no pun intended) technology, recharging a large battery is much less so.

[@fr57ujf]

You can't swap them mid-flight.

[@caav56]

@@fr57ujf But you *can* do it in airport, as passengers and cargo leave the airplane.

[@fr57ujf]

Yes, but the point was that, with liquid fuel, the plane gets lighter the longer the flight lasts. This decreases the load and increases the average fuel efficiency of the flight. With batteries, you have to carry the same weight throughout the flight.

[@larsnystrom6698]

The only problem with an electric aircraft is low energy to weigh of batteries. But even so, they are viable for short distance travel. That travel distance will grow as batteries improve. It's the right time now to start developing the aircrafts, so we have them to put those improved batteries in. It's odd how non-engeneers are so quick at finding problems, even inventing them, but so unwilling to take the next step and solve them!

It will be at least 50-60 years before we see anything fly on electric engines". I think about that article a lot, when seeing the evolution like in this video

The battery fire concerns all go away when you start talking about Sodium Ion batteries. They are ALMOST caught up with Li-ion AND improving FASTER, so there is every chance they will soon be the battery of choice. They are cheaper to produce, last for more cycles, And they don't catch fire!

[@williamarmstrong7199]

They never existed! The claims about EV fires is 90% fake. EV cars are 20 to 40 times LESS common than fossil engine fires. This reality is from Insurance company records. Most of the fires you see are early Hybrid vehicles. BMW for instance have more vehicle fires in their fossil cars in the UK, in one year than World wide EV fires in the last 15 years! They have faulty plastic EGR valves that catch fire and burn the vehicle to the ground.

37:10 BS. The difference between a fuel fire and a battery fire is that there is a possibility to extinguish a fuel fire. You can even dump the fuel, turn on the extinguishers and glide the plane towards the ground. NOTHING can stop a lithium battery fire. When electric cars catch fire, they have to let it burn itself out. You can do several things to stop a fire on a modern airplane. If you catch fire in an electric plane mid flight, you can either jump off quickly, or you can crash and burn. No 3rd alternative.

[@billmullins6833]

Sctually, a group in Sweden (IIRC) has figured out how to put out a fire in an auto battery pack. They flood it with super cooled, maximally salty brine. I've seen the videos. It actually works! Unfortunately that isn't going to help you in that 19 pax e-plane at cruise altitude.

@TacticalLulu From all the world wide examples of the firefighters spraying water on a burning electric car, only to give up and focus on containing the fire to the vehicle. When water contacts the lithium, you get a runaway chemical reaction. Feeding water to a fire of the level will potentially add "fuel to the fire" as the next cells now are damaged by the heat, and gets into contact with more water, starting another out of control burn.

I admire the young inventors of our time. They could potentially provide an alternative to the large corporations that exploit us. A jet engine is heavy mainly because it includes sturdy metals to withstand extreme heat. Electric motors also generate heat, but not as much as engines, allowing us to use materials that can tolerate heat while remaining light. Although the battery may drain quickly, once the motor starts, it can recharge itself while in use. Even though they may have limited range and speed, it doesn't matter since we are aiming for a budget airline experience, not to mention their potential for future improvement. If there are any obstacles to this development, they would be our fixed mindset and corrupt politicians with their cozy relationships with big corporations. Hats off to these young engineers!

Very interesting video but a very misleading title. No mention of replacing long range jet aircraft with electric. Turboprop planes have commercial speeds of about 350 knots. Anybody want to fly an electric propeller plane from LA to Honolulu or Seattle to New York and take 8-9 hours to do it? This video made no mention of making an electric airliner that flies as fast as commercial jets do now. Long range aviation is all about getting there quicker not taking much longer. The exciting news about long range flights is the prototype supersonic jet being worked on now.

[@santaclaus0815]

The greatest savings potential is overlooked in the video: 1. Lower cruising speed is much more energy efficient. Long-distance propeller aircraft of the 1940s were much more fuel efficient than modern jet aircraft because of the lower speed. 2. The propeller is still far from maximum efficiency. 3. Wake turbulence: Instead of putting the engines at the wing tips, you can also do this with the fuselage. Such concepts already existed in the 1940s. This reduces the bending load on the wing and it is easier to build because it has an almost constant thickness over its length. Even biplanes would be conceivable with 2 fuselages on each end. This would create a large passenger capacity with the same aircraft width which limits the use of today's runways. The lower travel speed and thus longer travel time is compensated by the fact that the increased volume gives passengers more space and therefore more comfort, e.g. for good sleeping accommodations. This means that the flight does not become a waste of time for the passengers.

Lithium Ion Electric EV Batteries fade or lose capacity diminishing range per charge, even when sitting disused in a parked EV. Every cycle of the Li-Ion batteries also reduces capacity and eventually they are so worn out that internal resistance increases decreasing performance while capacity loss means less range. PHEV address this as do HEV by allowing the computer ECU to control when the gasoline range extender turns on to keep the fragile batteries warm, not frozen cold from winter or hot from summer sun as thermal stress also damages Li-Ion EV batteries, which often have heater and cooling systems to minimizes loses which are progressive or ongoing in terms of capacity loss from days or time and cycles of used capacity; the HEV and PHEV traction battery controller keeps the fragile batteries between 30 to 80 percent charged, so as to prolong the cell life, using the engine or onboard generator set to keep the battery charged or prevent over charging. 30-80% charging makes common lithium ion batteries last 200X longer with up to 20,000 cycles and 10 years of good use capacity, where regular 100% charging and deep discharge below 10% means battery fades to 70% initial capacity within 5 years and only 2000 cycles. LFP a little bit better but also lower voltage and lower energy density so much heavier in longer range EV's.

It baffles me why so many companies keep bothering to develop electric flight. With current battery tech, there is NO airplane or boat that can have range to make it worth the effort. The more power you want to bring, the heavier the batteries and the bigger and bigger the plane or boat becomes. Think square-cube rule. I tuned-out after the first idiotic BS claim of 2 hours and 500km range. The Pipistrel Velis Electro is a CURRENT, gorgeous, well engineered little plane and they're at least honest enough to report that it has a best-case range of 45 minutes. Planes have to have a 30 minute reserve, meaning that you can only fly 15 minute missions. Until there's a battery tech with MUCH higher density, none of these will ever be anything but an expensive curiosity.

[@u9Nails]

Hybrid ships are a thing. They have about a 25% fuel savings with battery electric propulsion and lower emissions. What you're really saying is that battery energy density needs to improve. The early Tesla Model S' had about a 246 Wh/kg battery. Likely experimental aircraft are testing with this grade of battery to keep costs low. Doubling this will double the range, given the same weight. Two battery manufacturers already have 500 Wh/kg batteries on the market for EVs. Their chemists are on target to have a 1,000 Wh/kg to market in 5 - 6 years.

[@fetB]

[@tilethio]

You know I did have the same opinion while watching this documentary until I considered other aspects of this project. For example, the range and speed of conventional airplanes come at the cost of being even heavier. Airplanes today fly because they have enormously large fuel under their enormous fuel tank, which comes with its associated gadgets, which adds to the weight. Additionally, kerosene engines have heavy titanium and other sturdy components designed to withstand extreme heat, while electric motors produce less heat, allowing for the use of lighter materials cooled by flowing air. Unlike conventional airplane engines, electric vehicles recharge their fuel while in use, leaving a responsible amount of charge in their battery. On the other hand, kerosene engines simply turn fuel into smoke, leaving behind an empty tank at the end of the runway. Boy! Early pioneers did not have perfect engines or airframes, and progress cannot wait for perfection.

@MISTERLeSkid Did you not understand that the video is outdated and there is so much tech currently out there that wasn't even mentioned? Toroidal propellers... Electronic ducted fans (EDF) ... Hydroxy fueled engines and generators... Carbon fiber construction... Flexible plastic based solar panels the thickness of a credit card... and lightweight! Imagine a double lithium ion battery pack with carbon fiber shielding combined with LC supercapacitors... In-flight recharging with solar panels built into the upper side of the wings and fuselage... with an extra large cabin that contains a hydrogen balloon for additional lift and reduced weight... an EDF with hydrogen burning afterburner for faster speeds... toroidal propellers on wingtip engines for normal cruising... As much power as those tesla batteries provide, 3000 nautical miles range in a Learjet sized electric aircraft would be easy... while carrying at least 20 passengers. But they will likely keep it under 20. There are certain restrictions and regulations that need to be met before an airframe can be proven to be within acceptable limits before the FAA would allow for larger passenger loads. Hydrogen fuel cells would also have much greater ranges when you bring the hydroxy generator on board the aircraft... 1 liter of water generates 1,700 liters of hydrogen gas plus oxygen gas... A few hundred gallons of water could conceivably fly you around the world...

Aviation batteries will want a very high energy density. As the batteries wear through cycling, they will need a new life in something else, such as marine ships or the utility grid power. There the batteries can have a 20+ year life before needing to be recycled. Once recycled the batteries are received as ore. Hammered into small bits and separated into components such as lithium, cobalt, nickel, steel, gold, copper, and plastics. Since it's a closed loop system, no pollutants are put into the air or sewage water.

I think if I was going to build an aircraft from scratch I would probably be a pilot and aeronautical engineer first. As a pilot for 24 years, I cringe at the thought of the wingtip mounted motors on the EVAITION. In the event of a wing mounted motor / propeller failure at a high power setting and high angle of attack would cause an immediate loss of control due to asymmetrical thrust. Your theory of eliminating a crab on final bc the engines are wingtip mounted is just pure ignorance of why the aircraft is in a crab to begin with. I’d give it a 100% chance of a prop strike on a gusty crosswind landing. And a 0% chance of ever being certified.

Coming from an aviation background i can understand why the push to develop electric propulsion aircraft, HOWEVER, one critical point about flying a plane on batteries vs fuel, is range and weight of batteries that comes to mind. A fuel powered aircraft fully fueled becomes lighter during its flight time as you burn off fuel , with the options of being able to climb to higher altitudes as you fly, which is an important safety factor when transporting very heavy payloads and flight planning . an electric storage battery on the other hand does not get any lighter as its energy capacity gets used up, meaning you need to fly lower altitudes even closer to ground based obstacles with greater risks of ground collisions (crashing) than the fuel powered aircraft which has vastly more effective range than an electric plane , and its the same with range on an electric car or Truck or Bus etc.I think it is safer to propel a ground based vehicle than an aircraft with electricity.

Combustion engines are wasting too much energy. Something like 35% efficency. Turbine engines are more efficient.

The biggest problem that electric powered transportation has been on board storage of energy that is to be used to power the vehicle. The battery technology the developers found to be the most applicable were to heavy and to large to give the range for practical use. The focus has been to reduce the weight while the energy density is increased that improves the range or duration to compete with fossil fuel modes of transportation. A man by the name of Stanley Mayer researching HHO technology from water took it to another level when he discovered that frequency and resonance was the key for using water for fuel in internal combustion engines (ICE) He developed a fuel injector that used water for the fuel supplied and injected a HHO mixture aka Browns gas directly into the combustion chamber of a four stroke engine in real time ! During the research he discovered not only the key to eliminating the volatile Browns gas drawback but also the high pressure fuel tank required to store the Hydrogen in liquid form. A bonus of his research he found that the two elements of water are neutral in their separate states not positive or negative. By passing through a non conductive tube that have copper induction coils out side the tubes entire length and adding plasma to the HHO the plasma attaches to the two neutral elements and generates large amounts of electrical current ! So much current that applied to a EV all you need for a battery in a closed loop system is enough to start the genset for continuous use, no refueling required to turn your props or wheels or fans! No emissions at all ! it can be applied every where electricity is needed like a cabin in the woods either open loop for heating and cooking with gas and the electricity to light up or charge your phone only topping off the water tank when low. Do you think with China wanting global control of everything manufactured and mined how long before they would want you to become commies and slaves to be used and abused ? What Stanley wanted for his work was recognition, he was giving it to manas a gift. What he received for his gift was death by poison after turning down an offer in billions to sell all his runs on water technology.
