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.
Everything about Tesla is groundbreaking, including its direct-sales model. Laws in New Jersey, Ohio, Texas and Michigan have sought to prevent the electric carmaker from bypassing third-party dealerships and selling cars directly to customers. Last week, Tesla scored a big win in Maryland, when the state's governor signed a bill allowing the company to operate its own dealerships in the state. In other green transportation news, a 28-year-old woman is preparing to row all the way from Japan to San Francisco in a rowboat, with no support vessel. Airplane manufacturers have yet to unlock the potential of 3D-printing airplane parts, but the engineers at GE Aviation recently conducted a test, offering a possible glimpse of the future. The team created a mini jet engine that can roar up to 33,000 RPM, and it comes right out of a 3D printer.
