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.
It's been a big week for planes, trains and automobiles as California (finally) announced plans to break ground on the US' first high-speed rail and we speculated on just how Elon Musk's 600MPH Hyperloop train will work. Inhabitat also brought you the scoop on BMW's 2014 i3, which is the world's first electric vehicle made mostly from carbon fiber. Green vehicles proved they could go the distance as a 65-year-old man embarked on a 1,200-mile journey in a solar-powered tricycle, and a crop of green-roofed buses brought lush air-purifying plants to congested city centers. And if you're planning an outdoor adventure this summer, you won't want to miss this caravan that doubles as a boat, Mini's new ultra compact luxury campers and the full-sized tent that fits in a pair of sneakers.
