Each globe combines vibrant artwork with our patented technology, creating a flawless rotation without batteries or messy cords. Hidden solar cells use ambient natural or artificial light for power, while the earth’s magnetic field provides the necessary torque. These elements work seamlessly to power a 'whisper-quiet' mechanism, allowing the globe to rotate within its clear outer shell. Each piece is assembled with such precision, it appears the inner and outer layers are one – rotating without any outside power source.
