The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of Science. With two conjoined 4.5 m (15 ft) aluminium spheres standing on columns 22 ft (6.7 m) tall, this generator can often obtain 2 MV (2 million volts).
Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.
European scientists developed machines to generate static electricity decades earlier. In 1663, Otto von Guericke generated static electricity with a device that used a sphere of sulfur. [ 1 ] Francis Hauksbee developed a more advanced electrostatic generator around 1704 using a glass bulb that had a vacuum.

The kinetic energy is wasted as heat when the water drops land in the buckets, so when considered as an electric power generator the Kelvin machine is very inefficient. However, the principle of operation is the same as with other forms of hydroelectric power. As always, energy is conserved.
It’s more than 100 feet long, at least 300 years old and visible from space. The world’s largest coral has just been discovered in the southwest Pacific Ocean, scientists announced Wednesday ...
As the world’s largest iceberg, the colossus A23a is of great interest to scientists, who have closely monitored the frozen block since it calved from Antarctica’s Filchner-Ronne ice shelf in ...
