geodesic dome

1. A geodesic dome is a spherical or partial-spherical shell structure or lattice shell based on a network of great circles (geodesics) positioned on the surface of a sphere.

2. A strong prefabricated enclosure constructed of lightweight bars forming a grid of polygons, with no internal supports.

2. A strong prefabricated enclosure constructed of lightweight bars forming a grid of polygons, with no internal supports.

The dome is energy efficient because it requires less building material and has less surface area, because heat loss due to wind turbulence is decreased, and because its shape minimizes air leakage.

geodesic line, geodetic line

1. The line of shortest distance between any two points on a mathematically defined surface.

2. Specifically, on the surface of the earth, a line of double curvature; which usually lies between the two normal section lines determined by the two points.
