PowerPod has created a super ecologically-friendly house. The roof is designed with solar panels, and they bounce sun off each other to ensure maximum exposure and absorption of the sun. It funnels rain for collection and reuse, and the solar panels heat the water. So far, no carbon use.
These pre-fab homes have extra high ceilings with plenty of windows to let in a lot of natural light, and they're well-insulated so you don't loose a lot of heat or cool. Extra thought went into the technology of these houses, including heated floors with "a radiant heating system that circulates hot water through insulated subflooring."
