Re: Europe and Asia moving ahead with workable hyperloop.

It just seems like a massively expensive way to bring even more illegal immigrants into Europe.

The track is two tubes, and the pagoda roof thing looks cosmetic and expensive.

Aircraft have the same problems, when they fail. You engineer the system so that it doesn't fail often.

Mass transport is always expensive, but it becomes cost-effective if it moves enough people. This is just taking the idea behind New York subway system, the London Underground, the Paris Metro and the San Francisco BART, and stretching it a bit further.

But a whole lot more of them fly anyway.

People get sick on planes in flight pretty regularly and doesn't get much media attention;

What's that supposed to mean?

There aren't enough illegal immigrants to constitute an attractive market. Hyperloops don't make sense unless they are moving lots of people every days. They are aimed at commuters, not immigrants.

It seems to be covered with solar cells, and the shape would maximise their collection efficiency. That isn't cosmetic.

But not on Paris.

A a can't do reasoning,

From a a's frankly bizarre - and probably insane - point of view

A a needs to take himself to a real mental hospital and get treatment for his real mental problems.

Hasn't it always been that way?

Fred's link provides a little information. A capsule is said to weigh 5 tons and is powered by internal batteries, With 40 passengers and their luggage we might reach about 9000 kg. Bringing that up to speed, 1220 km/hr, requires about 280 kWh. That requires roughly 1600 kg of batteries if we're allowed to deplete them entirely, but more likely about double that to improve battery lifetime and to have margin for other purposes. That would leave about two tons for the capsule structure, motors and levitation magnets included.

That looks totally unrealistic. Did I miss something?

metric, I suppose. With 40 passengers and their luggage,

It seems unlikely that the batteries will do the propulsion or the levitation.Magnalev trains seem to put the power into the tracks and more or less incidentally induce enough current in the moving capsule to create the magnetic fields that move it and lift it.

A a is the idiot here. There are no pills that could cure his ignorance, or get him to state where he could appreciate quite how irrelevant he really is.

Such as slowing down again. ;)

A a can't even invent his own insults, and can't manage to properly copy the one's he recycled. You need to specify a mental hospital to get the full effect.

I take my pills pretty regularly, but they are mostly intended to control my blood pressure and the state of my arteries, rather than my mood. There aren't any pills that could cure what ails a a. This is one that would leave him in a state that was less annoying here, but you'd need vulture to clean up the residual mess which would otherwise annoy his neighbours.

Completely missing the point, that the hyper loop concept uses gravity for acceleration, and gravity for deceleration, and the 'kWh' value is identical to the potential energy of the endpoints minus that of the trajectory nadir.

Envision one of those cars, traveling at 1200 km/h, going wrong and tumbling inside the tube. It won't be "noiseless" any more.

Gravity? How would that work?

According to my civil engineering contacts, "always".

Simple, running a tunnel 12 km deep or so. It's going to cost a bit, but that's not a problem, now is it?
