Who says solar and wind can’t provide enough energy for a modern lifestyle? This giant, terrifying robot with a geodesic dome shell and 12 crustaceanesque legs derives its power from a wind turbine and a roof-mounted solar panel. And if wind and solar can power your unsettling crab robot, what else do you really need?

The Walking Pod was built by Scott Parenteau, who recently exhibited it at the Maker Faire inventor expo. Parenteau built his monstrosity out of scrap metal and industrial dishwasher parts, so it’s not only clean-energy-powered but also recycled. In other words, gargantuan crab-bots might just be the future of green technology. If that idea upsets you, get with the times.
