The device that bears his name has the ability to produce extremely high voltages as high as 20 million volts. As well as making your hair stand on end, these machines were used to accelerate particles through millions of volts. It uses a moving belt that accumulates charge on a hollow metal structure designed like a globe, placed on the top of a column that is insulating in nature and thus, creating a very high electric potential in the order of a few million volts.
These charges are generated the same way that you can generate an electrical charge when you rub your feet on the carpet. In 2005 the band reformed, and are still musically active with a lineup of hammill, organist.
