  • No.

    • energy requirements will always be higher vs surface transit

    • mechanical complexity will increase mechanical failures. these mechanical failures are much more likely to lead to death or severe injury or extensive damage.

    • you think self driving is bad now? It’s not. Planes can largely fly themselves, but that’s not the hard part. It’s the everything else, including maintaining safe patterns and separation. If everyone jumped to air travel in a city congestion just moves into the air, and you’ll have shit loads of accidents. Throw in improperly maintained air craft because that shit is expensive and you have a recipe for 9/11-level accidents on a daily basis.

    Mass transit is the way to go.














  • Well, not an engineer myself, either, but generally speaking that would greatly increase the systems complexity, which generally increases maintenance costs, down time, and the initial cost of the system.

    You might be able to eke out a bit more power, but there’s more to the decision than total output and how efficient it is.

    What I would imagine were a fusion-powered MHD being useful would be as a front end to fusion-based plasma propulsion. (Basically something like the VSIMR, Hall effect or whatever plasma thruster, where the fusion reaction generates both some power to create the thrust and its exhaust plasma is also the reaction mass.(I mentioned I’m not an engineer… right? Just an incorrigible nerd who likes sci-fi.)
