Hyperloop has achieved significant liftoff in the northern Netherlands.

A 420-meter or quarter-mile white steel tube running alongside a railway line in the windswept northern Netherlands could usher in a new era in the transportation of people and freight.

Hyperloop is the superfast, cutting edge transport technology first envisaged by business magnate Elon Musk. (CNN) - An eco-friendly version of the Hyperloop network is in the works, powered by a skin of solar-powered modules and wind turbine forests, and complete with parks and urban farming spaces. The new sustainable design, by Chinese architects MAD, is made in collaboration with Hyperloop Transportation Technologies and aims to create "enhanced connectivity between cities and people", the team says. The transportation tunnels, MAD says, will be fitted with "bendable solar panel skin modules" that will power the Hyperloop itself and interactive information boards. Meanwhile, bladeless wind turbine forests will also be built along the Hyperloop system -- a move the designers hope will generate power for the transportation network and lower the project's energy costs.
