The Domespace house plans were designed to optimize warmth by natural means, so the house actually turns to follow the sun and gain as much energy as it needs to keep temperature at an ideal level. If you don’t want warmth and sun-rays you can just set it to turn its windows away from the sun. You can command the engine to turn the house at a certain time or program it to do a full day rotation.
These days Domespace houses only come with an engine, but a few years ago if you wanted to buy or rent a house, you had to move them manually. I can imagine such a house for lease: “It’s a great house, spacy, full of light…only thing is you have to turn it yourself”.
