The I-Shovel is a new device that promises to automate this task—much like the Roomba and the Husqvarna lawnmower have done for other annoying chores. According to the project website, the I-Shovel can automatically detect snow accumulation and clear the driveway when it deems that the snowfall is significant enough to be cleared.
As for power consumption, the I-Shovel would utilize a rechargeable battery with a solar power option, which would make it eco-friendly and inexpensive to operate. Unfortunately for our friends in cold weather climates, the I-Shovel is currently in a prototype phase—but the designers are actively searching for partnerships to develop the design into a production appliance.
