In Vietnam, village relocations did happen, but cash wouldn't have helped; the new locations were prepped in advance, with wells dug and roads cleared and such, before the moves. By the US Army Corps of Engineers.
The dwellings weren't going to be made of store-bought manufactured goods, and Amazon Prime didn't deliver there...
One problem with the California No-Speed-Rail Project, the Train to Nowhere, is that acquiting right-of-way generates a couple hundred lawsuits per mile.

It's more than twice as nice (than 777) to be a passenger on though. The airlines have trouble keeping them full enough though, except on limited routes.
Problem? That means a couple hundred disputes settled by court order, per mile. That's a SOLUTION. Drafting random folk (navvies) for workers and confiscating everything in sight would be (has been, historically) a problem.
If you don't like the courts' decisions, that's a personal problem, not California's.
doing the math if you start out at 1 G perpendicular instantaneously for
10 minutes acceleration and then decelerate at 1 G the other way for another 10 gets you across the Atlantic, approximately, in 20 minutes at a top speed of around 14,500 mph but that's going to be a really uncomfortable 20 minutes I think. 1 G instantaneous acceleration and maintaining it is like being fired off in a Model S Ludicrous Mode continually for 10 min, tolerable for an astronaut but not old ladies even with tilting seats. forget about having a cup of tea on your trip.It would have to be brought up slower but then your top speed is going to be less. 2-3000 mph with a travel time of about an hour and a half sounds fine to me. Makes the engineering simpler and there's a point of diminishing returns on selling travel time vs. having premium snacks and beverages available on the trip.
Maybe if you arranged things just right you could get the acceleration forces and the weightlessness effect to cancel each other in such a way that the passengers would feel less discomfort but that sounds like one of those "it looks good on paper" ideas.
It does indeed. He must have got rid of his A380, then. At one time it seems he had *both* aircraft:
I'm inclined to think the Russian people could have made better use of all the money he "appropriated" from Russia, though.

You are clearly right. The article is talking about a particular copper-oxide super-conductor and only comparing it with similar compounds, not the YBaCuO compounds that George Herold has reminded me about.

That's generally true for all high voltage transmission lines.

The infrastructure required to support the existing cables isn't cheap.
As with all technical advances, it is going to be killed by economics until the technology gets cheap enough to be useful.
It's never clear when that's going to happen, and spending a little research money on pushing towards that cheap solution is perfectly sensible.

That was the point of my statements about the acceleration vs. the jerk. I f the 1 G is ramped up over a few seconds it isn't so much to deal with. S itting in a seat for 20 minutes won't be enough time to worry with tea or a nything else. In a skyscraper, do they serve tea in the elevators?
What? I think you have it backwards. People would be very happy to get th ere in 20 or even 30 minutes without snacks vs. an 90 minutes with snacks. I don't get why you think snacks are so important. Do they serve snacks i n cabs?
The whole point is if practical, this would be an entirely new way to trave l across the oceans of the world. I'm not sure it is really practical in a ny sense however.

I think they should design a contained (below ground) rail system where the train is mag-lev and mag-motive, but has overhead suspension (like the roller coasters) when failure or pause in the meg-lev happens. That way, the tunnel can have banked turns incorporated as well. Also, other utilties (DC links, etc.) can be included in the Tunnel block.
Anything above ground is vulnerable and a waste of the space required to be set aside for the run.
Fuck the scenic route shit. You want fast transport. Period!
That pretty much covers it. What more could anyone possibly want?
That's cheating.
Just don't be one of the first! That's my best advice. Let others de-bug the thing first. I'm sure there'll be plenty of them. Poor fools! ;-)

There was an article in the Proceedings of the IEEE a few decades ago that wanted to dig evacuated tunnels between major cities.
If you make them parabolic, you just drop a train in a one end, and it pops up at the other end in 80 minutes, independent of the distance travelled.
You need magnetic levitation to make the process almost friction free, and you'd need some kind of electro-magnetic drive to make up for the residual frictional losses.
The long distance routes wouldn't have been all that practical, since they start dipping into the molten core of the earth, but it was a cute idea.

Oh, they could build one over at Yellowstone!
Actually an easy experiment could be done in a large salt dome (which they all are).
easy digging. Just mind the heat once the depths are achieved.
The bottom would be like the Gateway Arch turned upside down (only much bigger).
They would have to build that part ahead of time. So one digs a big long deep slot to get that down there, and then builds the two tunnels to connect to the surface.
Way too much digging.
flat run, tunnel near the surface, always powered, not a big deal.
There could easily be plenty of "coast" "declines" to go down with less power. Levitated roller coasters can coast a looong way.
Do not have to fully evacuate the tunnels either. We could even use a pressurized system with seal flaps surrounding the train at specific points along its 'fuselage'. There could even be a test design where directional jets blow air in line with the run and assist in the movement of the "projectile" in a 'blowgun' manner. Sealing agaisnt vacuum or pressure... both pose major problems at those scales.
Why would a long distance underground tunnel have turns?
I have no idea if such a tunnel is remotely practical. There is the Chunnel which must have been an ambitious project, breaking new ground . I expect an intercontinental tunnel would be a whole new ballgame though.

I've not looked at the math on this. There are an infinite number of parab olas between two points in a plane. How do you select the one that gives a n 80 minute path? I don't think I can solve that with algebra unless there is some simplification I'm not thinking of.

Would the magnetic field of this coil be of sufficient intensity in order to redistribute the flow of liquid iron of the Earth's core? Would the Earth's magnetic field collapse as a consequence?

Airbus steals Paris Air Show with twice as many new plane orders than Boein g
Published time: 21 Jun, 2019 15:32
European aerospace company Airbus has dominated Le Bourget airfield as it e asily outpaced US rival Boeing with the number of orders for its aircraft o n the final day of trading at the Paris Air Show.
The business program at one of the world?s largest aerospace-indust ry exhibitions closed on Thursday. Over the four days, Airbus secured firm orders, letters of intent and memorandums-of-understanding for 595 jets, wh ile Boeing had orders for 234 planes, according to the aviation consulting firm IBA.iQ which tracks aircraft orders.
Boeing had a rough start from the very beginning of the show on Monday when the company recorded zero orders, while its main competitor in the large j et airliner market, Airbus, won 100 orders.
Boeing inked the first deal at the 2019 Paris Air Show on Tuesday, as South Korea?s biggest carrier Korean Air Lines Co Ltd announced the purc hase of 20 Boeing 787-10s and a lease on 10 Boeing 787-9s. On Wednesday, it won its first orders for 200 Boeing 737 Max planes, a surprise since the a ircraft were grounded in most parts of the world after two fatal crashes.

Due to their fumbling, inompetence, and coverup, I would think carefully 2 or three times before getting on a Boeing plane. I understand many other cu stomers feel the same.
