Hyperloop One claims that its prototype ultra-fast train has completed a first full systems test in a vacuum, reaching a speed of 70 mph. The sled was able to magnetically levitate on the track for 5.3 seconds and reached nearly 2Gs of acceleration according to the company.
The test was conducted privately but Hyperloop One offered some video that included footage from testing. Based on that footage a lightweight skeleton sled uses a linear motor to accelerate, levitates briefly, and then comes to a halt as the brakes are applied.
The company is now entering the next phase of testing with the goal of reaching 250 mph. A concept first conceived by Elon Musk in 2013, the hyperloop theoretically can send aluminum pods filled with passengers or cargo through a nearly airless tube at speeds of up to 750 mph.
The aerodynamic pod is 28 feet long and constructed of structural aluminum and carbon fiber. Using electromagnetic propulsion and mag-lev technology, it’s designed to carry both cargo and human passengers at near supersonic speeds, Hyperloop One says.
For those who don’t know what Hyperloop is:
The Hyperloop uses a linear electric motor to accelerate and decelerate an electromagnetically levitated pod through a low-pressure tube. The vehicle will glide silently for miles at speeds of up to 620mph (1,000 km/h) with no turbulence. The system is designed to be entirely autonomous, quiet and on-demand (departures every 10–20 seconds) and, as it is built on columns or tunneled underground, eliminates the dangers of at-grade crossings and requires much smaller rights of way than high-speed rail or a highway.
