December 20, 1901Robert J. Van de Graaff / Date of birth
Robert Jemison Van de Graaff, (born Dec. 20, 1901, Tuscaloosa, Ala., U.S.—died Jan. 16, 1967, Boston, Mass.), American physicist and inventor of the Van de Graaff generator, a type of high-voltage electrostatic generator that serves as a type of particle accelerator.
Can you make Van de Graaff generator home?
The bottom roller has an extended rod to either power it using a drill or add the motor. I used the inner roller of a correction tape and a washer to make the belt pulley on the bottom roller. And the belt pulley on the motor is made out of two rivet ends chopped off and epoxied to the motor.
