Elon Musk’s dream of a hyperloop transport system may be closer than he thought, with Colorado-based company ET3 planning to build and test its own version of the super-fast technology. ET3, which stands for Evacuated Tube Transport Technologies, is described as “space travel on Earth.”
The transport system will be silent, low cost, safe, fast, and electric. Car sized passenger capsules carrying up to six people will be able to travel faster than jets in 1.5m diameter tubes at speeds of up to 4,000 mph.
Business Insider reports that the passengers will only feel the G-forces similar to a car ride. Air is permanently removed from the two-way tubes that are built along a travel route and airlocks at stations allow the 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 later regenerated as the capsules slow down. ET3 plans to build a 3-mile long version for testing by the end of the year.
