Middle East Hyperloop - Gittin Er Done

10/27/2016 11:58 PM

“We’re not waiting for new technology like carbon nanofiber or anything in order to do this. We have everything we need to do it and it’s a matter of doing it in the best possible way,” Lange added.

Looks like a James Bond design!

Evacuated Tubes are WAY too problematic. Just a plain old electric airplane in a tube would do just fine.

Maybe something like this.

Why put airplanes in a tube? They work just fine in open air.

Definitely not the scenic route or for the claustrophobic. A big no thanks from me.

I think donning a set of VR goggles would be commonplace

-Keeping order / monitoring passengers

-to provide virtual scenery along the route

-create an artificially large interior to help deal with claustrophobia

-The "larger" interior will allow passengers to be virtually seated with all of their travel companions regardless of their actual position in the tube

Good luck! All the oil money in the world won't solve the problems of pulling a vacuum on a volume of 1.1E15 liters. It takes CERN 2-3 weeks to pull a 0.1 Pa vacuum on the LHC (Large Hadron Collider), and the total volume is many orders of magnitude smaller.

Then there's the diurnal change in linear dimension of a 150km aluminum tube, as it grows 105m during a 25C temperature change, lots of leak-proof, vibration resistant expansion joints will be required, not to mention the supports required to keep the whole tube in perfect alignment end to end.

And let's not forget the MWhrs necessary to run those vacuum pumps, but I'm sure the guys at BIG have already done those calculations on a napkin or two, so I hope that better minds than mine have already figured it all out.

And one day some terrorist will blow up one of the supports, and we'll see how much Nature abhors a vacuum.

What a gas that would be.. And after spending untold billions.

I'm not a proponent for the system ..I think it's a hyper loopy waste of tech that would be used by and for the super elite.

Sure there will be cheap seats,, wink wink..

It wouldn't be operated by Southwest

The idea of Electrically Powered Aerodynamic Flight in and Enclosed Guideway may have some merit; but not when it includes an evacuated tube.

An electromagnetic turbine mounted inside a lifting body, in a properly shaped tube, where the clearances are close enough to induce ubiquitous ground effect surrounding the lifting body, would lower the air density to the front of the aircraft, thus reducing the drag force.

The idea of no on-board combustible fuel to lug through 10,000 meters of gravitational potential is also a plus.

The very stable flight environment of an enclosed guideway would allow the elimination of most aerodynamic control surfaces; which would decrease both aerodynamic cross-section and induced drag.
