Spheres minimize surface area per unit of volume. As heat loss in a building is proportional to its exposed surface area, this means they're potentially very thermally efficient. (Less good for collecting sunlight if you're going to cover them in PV panels, though.)
- misja111 3y agoThis is a great argument, except that the extra space that makes the building so efficient compared to a cube, is space that mostly can't be used.
