More High-Voltage science action. These Van de Graaff Generators were built by Robert J. Van de Graaff himself for MIT in the early 1930’s. Unlike the Tesla Coil, the Van de Graaff generator is an electrostatic machine which uses a moving belt to accumulate electrostatic voltages on a hollow metal sphere. The machines above were capable of producing 5,000,000 volts and were designed to accelerate subatomic particles to very high velocities for the bombardment and study of atomic nuclei. These goliath machines now reside in the Museum of Science in Boston.
