A prototype for a house that moves to follow the sun for optimal solar power is currently being built in Portugal. via fastcoexist
One of the many trials of solar power: Solar panels work best if they’re directly under the sun, and since the sun moves through the day, a fixed panel doesn’t work as well as it could most of the time. A new house solves the problem in an unusual way: As the Earth rotates, the house moves with it. The panels on the roof always soak up as much sunlight as possible.
