Thunderf00t BUSTS the Hyperloop concept

Payback says...

It's not IN a vacuum. the pressure is just very low, like a high-altitude jet airliner. The skis the pod runs on aren't even electromagnetic, they use micro jets of compressed air, like an air-hockey table.

As for Thunderfoot, I get he likes debunking things like those retarded snake-oil "smart pavement" people. However, saying Musk is one of them is ignoring what Elon's already accomplished. I can GUARANTEE Elon Musk has dumped more money than Thunderfoot will make in his lifetime in engineers and pure scientists just to see if it was FEASIBLE, let alone possible.

Using a trubine in a vacuum doesnt make any sense. I thought it was magnetically driven like the bullet train.

My Fusion Reactor's Making A Weird Noise - Tom Scott

Payback says...

Probably a fibre-optic tube. One would think those electromagnets would play holy hell with a CCD.

I don't know what's more impressive. The entire experience, or the fact that there is a camera inside the reactor.

Amazing stuff through and through.

Very neat idea!

If you replaced the magnets with a non-magnetic material conductively glued onto the magnet, it would still work. From wikipedia on 'electromechanical solenoid',

Electromechanical solenoids consist of an electromagnetically inductive coil, wound around a movable steel or iron slug (termed the armature). The coil is shaped such that the armature can be moved in and out of the center, altering the coil's inductance and thereby becoming an electromagnet. The armature is used to provide a mechanical force to some mechanism (such as controlling a pneumatic valve). Although typically weak over anything but very short distances, solenoids may be controlled directly by a controller circuit, and thus have very quick reaction times.
The force applied to the armature is proportional to the change in inductance of the coil with respect to the change in position of the armature, and the current flowing through the coil (see Faraday's law of induction). The force applied to the armature will always move the armature in a direction that increases the coil's inductance.

The whole capitalism versus socialism thing is so anticlimactic because you'd imagine any pattern in existence has the potential to provide a service; and in order to find the most optimal setup, you'd need a combination of all types of ideas. You don't discredit gravitational force because you like electromagnetic force better, citing the horrors which gravity has wrought upon mankind.

There's always going to be some form of capitalism. Want all the latest toys, bigger house, luxury car, yeah you're going to have to have a high paying job for stuff like that.

It will take a long time, but people will eventually draw some lines and decide that certain things are immoral to make profit off of or at the very least regulate such things heavily to keep greed in check.

We have to find a better mix of capitalism and socialism.
