  1. I wont say hydrogen is useless. It has uses in space, metal production, and submarines. Niche uses like that. For EVs of any type or most grid storage? Hell no. Hydrogen loves to leak and corrode things. The air fuel ratio for it to combust is pretty bad as it takes a smaller amount of gas in the air to do so. Then the fact the volumetric density is so terrible. The cost to produce is high. The materials required to make a fuel cell are high. Everything about it is a massive headache. I've been told hydrogen usage is funded by oil companies. The more I learn about it the more I think that is true. There are better options. I just saw an electric jet engine that uses LNG. It was awesome.

  2. Agreed. No reason in today's day and age not to just have both for redundancy. In fact I'm surprised it isn't mandatory for intercontinental flights. Gaps in the data? Find the box. If no gaps? Well no need to spend god knows how much to go searching in the ocean for an incredibly tiny piece of wreckage that could be anywhere in a huge radius. Seriously it can't be that hard. Ya know those planes are streaming more internet.

  3. The merger didn't seem to help. With that said them pushing this back isn't necessarily a bad thing. We don't a repeat of the other 737 Max, do we? Airliners are becoming much more complicated, and customers expect more. I mean they have to work with GE on everything on the new GE9X. That cannot be easy with all the parameters. Question for anyone in the know. Why the hell haven't cockpits or components become simpler yet? Is it really necessary to have all those damn buttons these days. They need to invest in a bunch of touch screens, with dials or buttons for key elements that are used all the time. Have smart features that show you what is needed. Wiring a cockpit has to be a pain in me arse. Touchscreens that can be used for all of a companies airliners. PS: Huh, lithium alloy. Gotta look that up. Didn't realize lithium could be good structurally.

  4. Why would you care as a CEO? You'd be getting a bonus if you failed, and made the wrong choice. Then get an other one for laying off people, and call it, "restructuring". Yet putting all your eggs in a basket is stupid. Seems like they've got enough contracts to ride for a long time. Would have to gut the company, and keep the best engineers. Me? I would try to get government contracts, and branch out to other engines or motors. Yet I would focus on technology like Rotating Detotnation Engines. To my knowledge that will be the future for both civil and military aircraft as far as a technological leap. Simple in principle, but incredibly hard. Think it is even better than the hybrid SCRAM jets. Those seem complicated as hell to me, compared to a RDE. You would think humans would know how to light and keep a fire burning no matter the conditions. Being pyromaniacs by nature, and all, hah.

  5. Boeing is dabbling in some generational leaps right now with their hybrid RED engines, and that new wing design. If they can get a rotating detonation engine working. They'd destroy the competition. Sandbox just dropped a video on the new engine designs they are working on. What surprises me is how far ahead they are. Anyway maybe that is why they are doing what they are doing. Just waiting when the time is right to develop a new type, and invest in that.

  6. ​ @greenflightacademy Generally the Aerospace industry is the first adopters of many technologies too. Since they are willing to spend the extra price to improve performance. Which is great as that generally means that technology will trickle down to the consumer level. There are many battery technologies right now in the lab, that don't make sense at the moment to produce at scale for cars for example. If there is more uses in the aerospace industry for electrical planes? Then it will speed up development, because they are willing to spend 10x more for better battery densities. Those improvements then when trickle down to things like cars, cellphones, and other consumer products. So I'm glad they found uses even if it is just trainers for now. Personally I think E planes will revolutionize air travel. Instead of large planes that carry a lot far. We would be using them to transport a small amount of people from X to Y within maybe anywhere from 20 to 1k mile radius. Basically regional flights. Keep gas for everything else. Espdcially trans continental. Remember people. We are already on the first steps to air taxis that have VTOL capabilities. The rich will use them first, replacing helicopters. As battery tech improves us plebs will be using it.

  7. Yeah it is just costing Russia a premium at most honestly. Without an effort to enforce it? It will be relatively easy, and possibly expensive. Depends on the Black Market.
