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.
Coffee is what fuels us in the morning -- but it turns out that a cup of Joe can do much more than perk up sleepy office workers; this week a truck that runs entirely on coffee set a world record for the highest speed ever attained by a java-powered vehicle. That isn't the only green car news that broke this week -- with the Geneva Motor Show fast approaching, we've been keeping an ear to the ground for the latest from Switzerland. McLaren is set to officially unveil its 903-horsepower P1 hybrid supercar at the Geneva show, and Volkswagen will show off its new XL1 plug-in hybrid, which gets a whopping 261 miles to the gallon. Volvo, meanwhile, just launched the world's first car with external airbags to help protect pedestrians from serious injuries. But if you prefer bikes over cars, then you'll want to check out Bicycled Bikes, a unique set of bikes that are manufactured in Spain from upcycled car parts.
