Description
This large Van de Graff generator uniquely offers alternative drive modes, either hand-cranked or motor driven. Excellently constructed, the generator reliably delivers charge and sparks 10cm long and more immediately on setting it in motion, even under high humidity conditions. In handcranked mode the amount of charge generated can be seen to increase at higher cranking speeds, while the much faster motor-driven mode delivers a fast succession of sparks. The generator is 76cm high and features a 28cm diameter polished steel sphere, which is less vulnerable to dents and scratches than comparably sized aluminum spheres. A further unique feature of this generator is a built-in lamp close to the bottom of the belt that delivers a small amount of UV light when turned on. This can be seen to increase demand on the motor power. A set of accessories is included, containing a discharge wand with a grounding cord, an electric
plume, an electric whirl, a discharge bulb, a cord for connecting other electrostatic demonstration items, a spare charge belt and a spare motor drive belt. The generator measures 38cm x 23cm x 76cm.
