On a train, that would be fun trying to get a laptop or tablet to stay in place. Many larger devices use too much power for wireless.
That is just a matter of designing an induction pad with adequate capacity. Afterall induction technology is able to power entire streetcars, so it is hard to believe that there is a fundamental technical limitation inherent to the technology. A simple click-on clamp to hold the device in place would solve the problem of a a moving train that is capable of spilling an entire coffee mug on your lap fro the flimsy table in Coach too.On a train, that would be fun trying to get a laptop or tablet to stay in place.

It's possible that wireless charging is the future. It's also possible that it will always be a niche technology for lazy people with a fear of tangled cables.Ah, the future scares you a bit. That's understandable. But don't worry, we can probably put in one of these jacks for your phone. Though, like USB, there is still the risk of that darn wire accidentally getting tangled around something.Wireless charging is extremely inefficient, is based on proprietary designs, has patent license issues, and suffers from a total lack of backward compatibility. No thanks.Instead of an USB or an USB-C for simply providing power, I would much rather see a wireless charging pad, probably built directly into the fold-down tray. Even cars and Ikea furniture are moving toward offering a built-in wireless charge pads (Qi).
Don't have a clue. I haven't thought about power electronics since college, although I did interview for a job related to wireless charging. At my heart I'm a ones and zeroes guy.You electrical engineers and hi tech gurus are leaving us poor Luddites in the dark with this technical info!
It's a dirty job but someone has to do it! LOL
Providing 120V three-prong outlets would be reasonable future proof. However, I would think that a good way to future proof is to provide some some of modular outlet that operates off of 120V AC and can be replaced with any new standard.At a high level, decisions will have to be made how much effort (and money) will be spent in future proofing vs backward compatibility. Whatever decisions are made we can be reasonably certain that lots of people will be unhappy, and whatever is done will be obsolete before it is implemented on a widespread basis. Of course, at the speed with which fleet re-equipping is taking place, we may be having an entirely different conversation 5 years from now..
ADA (Americans with Disabilities Act) is pretty strict about heights for receptacles, etc and that drives heights (and would make overhead difficult, plus cords dangling would be a hassle for the person in the window seat). I think there is a different set of regulations for transit, but I would suspect outlet height would need to be accessible.Now that think of it, would overhead outlets make sense? My main issue with the wall outlets is that it gets awkward stringing a cable across the window seat passenger.
