Hasbeen

I'm sure you would, and rightly so. My message was to highlight how even people claiming to be purists are throwing in the towel. They have no souls. The future is looking increasingly shallow and meaningless.

Josephus; one of the current crop of billionaires had proposed just
your suggestion. It was to first to be installed between Los Angeles
and San Francisco. All quite practical but financially ?
Such techniques on a smaller scale were used for donkeys moving
telegrams around Sydney. The carrier is sent along by air pressure
so the speed might be limited to the speed of sound.
Nothing heard for a long time, probably dies on the vine.

For a moment there Bazz I thought you were talking about the pneumatic system used in department stores of old, for sending the sales docket & money from each point of sale to a central cashier to make change & send it back. A great system, but probably not very efficient.

Yes Hasbeen, I was talking about that system.
The Post Office had such a system, it ran from the Sydney GPO where
the telegrams arrived typed up by the operators sorted into the post
offices on the system.
It ran from the GPO to Haymarket PO and also to Kings Cross PO.
It may have gone elsewhere also. The pipes ran under George St through
the cable ducts which were standup and walk height.

Magnetic fields are used on Aircraft carriers to launch planes at high speed, more effective and faster than pure jet power. Sinilar with launching projectiles from large guns, much more powerful than explosives. and have no residue, or smoke.

Answer- Coil or rail gun technology requiring huge capacitor banks to drive them- probably due to the relatively short barrel- web videos explain similar builds. A transport system using this technology would probably be designed differently. It's often interesting to see people without any engineering knowledge- and no inclination to learn- trying to solve engineering problems- Hawking talked about the guy up the back of the theatre claiming that the world sat on the back of a turtle- Movie Idiocracy talked about pouring water on a nuclear reactor. This technology is like prohibitively expensive maglev- eg. Transrapid- nations have maglev to promote national prestige. Generally rolling friction is low so these technologies are unnecessary. Nicola Tesla transmitted power over distance- other ways of transmitting power over distance is by laser or microwave- and potentially power electric motors in cars- would require large changes to roads- and would limit cars to certain roads. It's possible that over a fifty year period that small scale systems could be developed. Sub-orbital gliding missiles could be used for mass air transportation systems over long distances but the acceleration perhaps wouldn't be ideal. Elon Musk's tube based system which has been around in various forms for about 150 years- though a few of the features of his system are novel. He envisaged an electric skate board system which hasn't materialised at this point.

Many people have chased the holy grail of mass transport some with more success than others- the British and French rail systems were successes- Henry Ford- others less so.

These successes relied on the carbon economy- wood and steam engines/ oil and ICE engines. We really haven't come up with a better way to store energy than carbon.

There are too many people in the world.
