O.7(2) - Solar Bug


This solar bug is designed in the shape of a dragonfly.  It can either be used outdoors or indoors.  Its motor is powered by a solar panel on its back, which converts radiant energy into electrical energy.  Infrared sensors also serve as its “eyes”, directing the bug towards the lamp.

O.7(3) - Solar Plane


No batteries required - this demo features solar panels built right into the wings of a small replica monoplane. When sunlight or bright light from a desk lamp hits the panels on the airplane, it generates electricity which turns the propeller on the miniature plane, causing it to fly in circles around the attached base. This is an excellent demonstration of solar power in action: if you cover up the solar panel, the propeller stops turning. Demo size: 15" diameter x 7.5" height.

O.7(4) - Sun Runner Stirling Engine

The Sun Runner, a solar-powered Stirling Engine, offers a dramatic demonstration of energy conversion. This motor and its parabolic mirror can be attached to any conventional camera tripod. When properly aimed at the sun, the polished aluminum parabolic mirror focuses incoming solar energy on the heat cap of the engine, which is converted to rotary motion. This engine can also run as a horizontal engine with alcohol burner.
