Evacuated Tube Transport could see round the world travel in 6 hours

Listen to this article

Designers behind the Evacuated Tube Transport (ET3) system say people could travel around the world in less than six hours through a network of elevated tubes.

The system could see ‘car sized passenger capsules travel in 1.5m diameter tubes on frictionless maglev’.

Air is ‘permanently removed from the two-way tubes that are built along a travel route. Airlocks at stations allow transfer of capsules without admitting air’.

Linear electric motors accelerate the capsules, which then coast through the vacuum for the remainder of the trip ‘using no additional power’. Most of the energy is regenerated as the capsules slow down, the designers said.

The pressurised vehicles are able to accommodate up to half a tonne of cargo or up to 6 passengers.

ET3 ‘can provide 50 times more transportation per kWh than electric cars or trains’, according to ET3’s creators.

Speed in initial ET3 systems would be 600km/h (370 mph) for in-state trips, and could be developed to 6,500 km/h (4,000 mph) for international travel that ‘will allow passenger or cargo travel from New York to Beijing in 2 hours’.

Designers said ET3 can be built for 1/10th the cost of high speed rail, or 1/4th the cost of a motorway.

  1. Is this e science fiction or is it really plausible? How are people supposed to survive during the travel time without oxygen, since the whole system is supposed to be on a vacuum?

  2. When the capsule air runs out, `common sense` would not renew it. A breakdown would result in the  evacuation of passengers bowels-not the `tube`.

  3. It wouldn’t work, there will always be a leak somewhere along the line.¬† This would be hard to locate and harder to fix.¬† Remember: ‘Nature abhors a vacuum’.

  4. I predict that such a system would last a week before a catastrophic terrorist attack by some lunatic bunch or other.
