I wonder if this could be solved for with detachable take-off booster. Gets you up in the air, then returns to the airport.
Couldn't you just start with a cable that detaches and is pulled back to the landing strip?

>Or, more likely, a slight improvement in your phone and much thinner phones. On laptops, we might see the return of more ports. // Please, no. I don't understand the utility of making something so expensive be so fragile and hard to hold. My phone is 5mm thick, that's already too thin for me. Does anyone want thinner phones or is it just a marketing thing?
The thinner the phone, the thicker the case I can put on it with the same total thickness. It's incredibly rare to see a case-less phone in the wild these days.

I don't use a case. If it were meant to be used with a case it would come built in. Iphones could easily double in thickness without making it harder to slip into a (male) pocket.

Why would you want a vehicle that only covered 95% of your use cases? It's like condoms - better to have it and not need it than need it and not have it.
It certainly makes sense on a personal level but when one multiplies this thought process by a given population there starts to be a compounded issue of excess material going into the construction of the vehicles, excess fuel being used to move them, and excess parking space used to store them, to name a few.
Sometimes someone dies as an immediate result, and for some it means waiting for another 5 minutes.

Wow, if the coating is so cheap perhaps it can replace activated charcoal elsewhere, too. Would it also triple the capacity of water filters?
I'm not exactly sure you want carbon nanotubes in your water filter. They are mechanically very similar to asbestos and seem to likewise damage lung tissue. Probably better not to ingest them?

I'm not so sure about that being an acceptable solution for civilian transportation… Even assuming automation can eliminate the risks and training overhead associated with in-flight refueling, there are still be some major hurdles that would need to be addressed before this could be considered a viable solution. The 3 big ones that come to mind are: What happens if the KC-135 misses the rendezvous? What if the chargi…
> What happens if the KC-135 misses the rendezvous? What if the charging port fails to work for some reason? The same thing that happens today with combustion aircraft: the crew makes an emergency landing if they can, or bails out and waits for a Seahawk to pick them up. This actually happens with fuel-driven aircraft regularly today.

Serious question, would nuclear powered planes be viable? As far as energy density goes it seems pretty hard to beat! https://xkcd.com/1162/
Yes, both USA and Soviet experimented with nuclear powered planes during the 60s. The problem was how to shield the pilots from radioactivity. https://en.wikipedia.org/wiki/Nuclear-powered_aircraft They also experimented with nuclear powered drones. https://www.popularmechanics.com/military/research/a33565112... And Russia now claims to have a nuclear engine that can make a cruise missile fly for days. https://en.wik…

Battery noob here: Will this achieve the energy density of fossil fuels? In other words, a 50 litre tank of petrol gets me around 500 km. What will a similar volume of these batteries get me?
IC and Fossil fuels still win out (particularly if you swap to gas turbine) but the numbers are much closer.
