Since ETT could help solve the problem (cities choked with cars) better than
insisting on a return to the old paradigm (trains and bikes), you the
moderator will choke off any information germane to the discussion that is
outside of YOUR personal definition of the problem.
For several examples of this tactic in action (protecting the paradigm) --
see the book: "Innovation and Public Policy - The case of personal rapid
transit" by Prof. Catherine G. Burke - University of Southern CA, 1979.

You are correct that pneumatic systems like the one installed by Alfred
Beach, the editor of "Scientific American" in NYC have not seen much use for
passenger or cargo transportation. They are not efficient in large sizes
since they rely on the movement of air for propulsion (the tubes were NOT
evacuated). ETT is NOT such a system as you allege.
In fact the thrust of my argument is a way to solve the well established
problem of car choked cities in a way that IS PROVEN to work. Cars replaced
trains and bikes because they were more sustainable - they offered a higher
benefit to cost ratio.
Offering a higher benefit to cost ratio than cars will stand the best chance
of their successful elimination. Suggesting what is socially unsustainable
IS a "pie in the sky solution". Regardless of your likely noble intentions,
what in fact you are calling "focusing on the real questions" is
characteristic of the typical rail industry sponsored ploys to legislate or
force the continued unsustainable use of heavily subsidized trains. This
tactic of the rail industry sells trains that go unused; the rail industry
could care less -- as long as they can squeeze a little more profit from
their colossal train production assets and political machine.

In fact, the engineering behind ETT is serious; serious enough that the ETT
is part of the 10 national 5 year plan for China, and the following Chinese
organizations partnered with us on our proposal for the Florida High Speed
Rail Authority (FHSRA). Our partners in China included:
*The Design Institute for the Chinese Ministry of Rail.
* The superconductivity R& D center of South west Transportation University
* Northern transportation university in Beijing; (These two universities
train about 70% of the transportation engineers in China.)
* The General Research Institute for Non-Ferrous Metals in Beijing.
* The Magnetic Materials Manufactures association of China (produces 90% of
the world supply of Nd-Fe super magnets).
* Professor Wang, the inventor of the worlds first (dec 2000) High
Temperature Superconductor Maglev (HTSM) to carry passengers.
* Dr. Zhang Yaoping, PhD in Transportation Engineering, principal of a
Beijing Spacecraft technologies company; etc.
The FHSRA engineering experts did not challenge our substantial engineering,
or our detailed cost analysis, and they even confirmed the likelihood of our
ability to meet our performance claims. Our proposal was eliminated from
consideration due to political reasons, (mostly the reasons typified in
Burke's book referenced above).
The energy used to maintain the vacuum is less than 1/100th of the energy
that would be used to overcome aerodynamic forces during a typical journey
of more than about 10 km by freeway, or by aircraft.

a potential path to achieving that worthy goal. Otherwise you risk becoming
part of the problem set contributing to car proliferation.
Judging by the varied, and reasonable responses to my initial post; your
threat to censor on-topic, respectful dialog is not warranted. Your message
could be interpreted to indicate that you may have a hidden agenda to
protect. I will give you the benefit of doubt, and guess that your action
is just one of failing to fully check your target before pulling the
