It's a concept that is nearly 100 year old.

...and already used on the moon since 1999.

I thought it was obvious that I was referring to the specific case of using it ("the compressor within a tube" concept) for mass transit on a large scale - and not the general concept of transport of an object in a low pressure tube - which has been around and used for years...
The comparison to solar roadways is bogus in either case.

Madrid - Barcelona; 621 km
San Francisco - Los Angeles; 616 km
The former used to be the busiest air route in the world (seats/day), now there's a high speed train, every 30 minutes that takes between 2h30m (nonstop) to 3h10m (two stops) at 300kmph, and MAD-BCN isn't in the top 20 air routes in the world.

In fact, its specific case of mass transit has been in use for almost 200 years.

Ok comparing this to solar roadways is just disingenuous.
With the solar roadway it's not a case of disproving it, it's a case of asking what's the benefit?
What is the point of combining solar panels with roads?
Conceptually right from the start there's not even a perceivable benefit to be understood there?
Where as with the vactrain i.e. Hyperloop, the supposed benefit is frictionless travel.
Maglev to get rid of wheel friction and a vacuum environment to get rid of air resistance.
On concept there IS a benefit and individually, the technologies already DO exist.
Vacuum tubes exist in the likes of LIGO which is probably the thinnest vacuum in the world and until
recently TWO completely different forms of Maglev trains existed as well.
The german transrapid and the japanese one (don't know it's name).
So like I said, completely unfair and disingenuous to suggest that this is in the same line as the
conceptually stupid solar roadway project.
