Those of you that live in snowier climates will drool over the I-Shovel, a battery powered robot that shovels the snow off your driveway, saving you countless hours of backbreaking labor over the course of a single winter. Its inventors claim that, despite its relatively underpowered motor, it keeps the driveway clear even in heavy snowfall; the trick, apparently, is that the robot constantly monitors the amount of snow on the driveway and springs into action whenever a significant but manageable layer has built up. Unfortunately, the I-Shovel is still a prototype, but with any luck you’ll be able to actually buy one soon. If you’re impatient, of course, you could always try building your own.
