Walking house ! This house was built in Denmark by a team of engineers to give an idea about an alternative eco-lifestyle. It is written in the offical walking house website that there are solar panels and little windmills to collect energy from the natural environment. It can collect the rain water and there is a toilet system as well.

This 6 legged hydrological living form was inspired by the traditional nomadic culture of Romanis. There is a crazy idea as well we should note. You can establish a walking village with thousands of walking houses, in theory.
