Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.
Tesla CEO Elon Musk wowed the tech and business worlds this week when he unveiled plans for a 700MPH solar-powered Hyperloop train that could catapult people from San Francisco to LA in just over half an hour. Although the plan is highly conceptual, nothing associated with Musk can be written off as fantasy these days. The news somehow managed to overshadow all other futuristic transportation stories, like Martin Aircraft's unveiling of a "practical" jetpack that can travel at speeds of up to 60MPH and reach an altitude of 8,000 feet. Meanwhile, German designer Andreas Blazunaj unveiled a sleek hybrid concept vehicle that looks more like a spaceship than a car. An Australian high school student designed a solar-powered car that could be used to transport pregnant Zimbabwean women to hospitals. And the team behind the Bloodhound Supersonic Car announced that it will use a 3D-printed nose cone in its attempt break the 1,000MPH speed record in summer 2015.
