@elektrotehnik94 Hyperloop is a scam for this century anyway. I wish that weren't true, but it isn't reasonable. Just too expensive and not worth it. Fast trains and Mag Levs that actually use their potential. Also EV planes. Hopefully we unlock lithium air chemistries. Max potential energy is nearly on par with kerosene!. Yet even without it. Batteries will get good enough for regional flights within 20 years. With a smaller cargo or shorter flight of course. Yet still electric motors have benefits like super cheap charging costs. Less maintenence. Also electric motors are much easier to make a tilt rotor crafr. Allowing for VTOL or STOL type aircraft like a drone for passenger flights. Hydrogens volumetric density seems like a non starter to me for cars or planes.
