Elon Musk has a great vision towards transport system. He has just tweeted this Monday morning that he "Will publish Hyperloop alpha design by Aug 12." SpaceX and Tesla Motors founder also states that "Critical feedback for improvements would be much appreciated."
Musk actually wants to set up a brand new public transportation system that is really fast. It will be self-powered indeed. Details of this alpha design are not much revealed. The Verge reports that it will be a 5th form of transportation added in previous four i.e. planes, trains, automobiles and boats.
This new transport system will be faster than a bullet train as it will be able to cover the 380 miles distance in 30 seconds. Musk previously revealed that "Hyperloop would be a cross between a Concorde, a rail gun, and an air hockey table." Let's wait folks till August to know more details about the Hyperloop project.
