HIGH POWER
Giant
Van de Graaff
Electrostatic Generators
( 400kV
& 600 kV )

Generate over 1/2 million volts to
produce crashing lightning bolts and perform fantastic electrostatic
experiments on an incredible
and spectacular scale!
A fascinating piece of equipment for education,
laboratory research, or just plain fun!

600,000 volt Van de
Graaff Generator with 17" collector sphere.

Demonstrate lightning,
lightning rods, St. Elmo's fire, repulsion of like charges,
electrostatic dust collection and the flow of ions. Create colorful
glowing demonstrations of the Aurora Borealis by heating water in a
sealed container and placing it near the generator.
Easy-to-build electrostatic projects can be scaled up to large and
impressive proportions.
Build & power ion drive engines and a variety of 'antigravity'
models that will silently float in mid-air using nothing but common
materials from around the house.
These huge generators are ideal for large auditorium or classroom
science demonstrations.
We offer two versions of the generator, a 600,000 volt model and a
400,000 volt model.
The larger 600,000 volt unit is equipped with a gigantic 17" diameter
polished Stainless Steel collector sphere. The 400,000 volt unit
features a 14" diameter polished
Stainless Steel collector.
Both generators are powered by a 3,000 rpm, 110v ac motor and produce a
current of approximately
10 microamps. Rock solid construction with an unbreakable
clear Lucite insulating column.
Other than the different collector sizes, the generators are identical
in construction.
A spare neoprene belt is included with either unit.
Booklet
of high voltage demonstrations & experiments is included. |

WARNING
- HIGH VOLTAGE DANGER!
While actual current produced in this device is low, there still
exists the potential of high voltage shock. We recommend extreme caution
and knowledgeable adult supervision at all times when operating high
voltage electrical equipment. People with cardiac pacemakers should
never operate this generator or approach it while in operation.
The
electrical fields produced could cause the pacemaker to be damaged or
malfunction. |

Build your own Van
de Graaff Generator using these high quality collector spheres.
The general rule of thumb for voltage output is 70,000 x sphere radius.
For the spheres above: 490,000 volts for 14" and 595,000 volts for 17".
Actual
voltage output depends on a variety of factors,
but this estimate is fairly accurate.
Both collector spheres have a 3.5" hole in the bottom - curved
inward to prevent high voltage corona losses.
Fabricated from highly polished Stainless Steel (far more durable and
dent-resistant than aluminum is).
The mirror polish eliminates parasite corona discharges and
increases voltage capacity by 4%. |
