Three Tier Radiometer

The Solar Radiometer is a technical marvel and object of beauty that easily shows how light becomes energy. Within each handblown glass sphere is a rotary vane wheel mounted on a metal tip and equipped with four plates, each coloured black on one side. Place our three tiered or single radiometer near a window and watch the lightmills convert light into kinetic energy, spinning up to 2000 revolutions per minute in warm conditions. A unique decorative and educational gift. Measures 46cm long, largest sphere has 10cm diameter.
