Right now, a two hour and 20 minute long flight connects Adelaide and Brisbane, Australia. If you want to drive, it’s a little over 21 hours by car. But architecture and design firm Weston Williamson thinks they can bring it all down to 90 minutes. In a recent proposal for a hyperloop connecting Adelaide to Brisbane, with stops in Melbourne, Canberra and Sydney, the company expands upon open source technology imagined by Elon Musk and SpaceX. This conceptual high-speed transportation system employs pressure reduced tubes and pressurized, passenger-carrying capsules. Test tracks are already underway and even the environment stands to benefit by such developments.
