Elon Musk gave quite a boost on twitter to the companies who tried to reach the theoretical 700MPH speeds in order for the Hyperloop to be real.
The twitter feed stated that “It’s all about the GAS”
The pods that the hyperloop moves through use one of three suspension systems: wheels, air bearing suspension and magnetic levitation. German WARR Hyperloop, who by the way achieved a speed of 201 mph dating back in August, are an example for wheel usage but the thing is that the wheels suffer from friction that can cause slowdown. Levitation on the other hand is used on a select few train tracks, and Hyperloop One tested at 192 mph, but on the other hand it’s uber expensive. The other alternative which is in front of the inventors are Air Bearings. They use a thin film of pressurized air and they can save money AND reduce friction.
“Air bearings offer stability and extremely low drag at a feasible cost by exploiting the ambient atmosphere in the tube,” Musk said in his 2013 paper. “Externally pressurized and aerodynamic air bearings are well suited for the Hyperloop due to exceptionally high stiffness, which is required to maintain stability at high speeds.”
So what does Musk propose to help this gas-based suspension system reach high speeds? More gas.

SpaceX held two competitions on the 0.8 mile test track, with a goal to get college teams and others, to put their minds on the pod design, rather than building a full-scale test track. It was the second time around when WARR Hyperloop made the record-breaking run.
The race to 700 mph, just became more interesting and any advancements which can reduce cost and improve speed, are more than welcome. One more idea is that on speeds under 100 mph, something similar to the airplane’s landing gear can be deployed and allow easier maneuvering of the pod.
This just goes to show that some things, never grow old.
