Plants don’t appear to move until you use time lapse photography. But when you do, you will notice that many plants almost imperceptibly follow the sun from sunrise to sunset. Can houses do the same thing?
Apparently they can but whether this can become something that can be mass produced remains to be seen. But the prototype is off the drawing board and on the sales floor. A Portuguese company called Casas em Movimento (Houses in Motion) has designed rotating solar-powered houses that follow the sun just like a sunflower to harness the maximum amount of solar energy.
The company dreams big. Manuel Vieira Lopes is the founder of Casas em Movimento and his ultimate vision is that smart cities would be created using rotating shops, libraries, schools, and other structures.
The homes are pre-programmed to move, and are able to generate a great deal of energy with the sun power they collect. The houses rotate 180 degrees, and the roofing hoods pivot 90 degrees. They can move separately or concurrently.
This all means that the energy generated from the rotation is 25,000 kilowatts per hour per year. A normal house of the same size uses just 5,000 kWh each year. What’s even more amazing is that the rotating houses can produce that much power using the energy comparable to six 60-watt light bulbs lit for an hour.
The houses are built with metal structure and have integrated mechanical foundations instead of concrete.
Homeowners can program the movement with their iPhone and similar devices because it is a smart house. In the winter they can harvest sun rays, and be cool in the summer by facing shade. The rotations happen in approximately twelve minute intervals, so you won’t be tossed from one side of your house to the other in one quick movement.
A rotating 1,000 sq. ft. home costs approximately $543,225.
