		Electrostatic generators such as the Van de Graaff generator, and variations as the Pelletron and the tandem generator, also find use in physics research.
		Edward Nairne developed an electrostatic generator in 1787 which introduced the ability to generate either positive or negative electricity, the first named being collected from the prime conductor carrying the collecting points and the second from the prime conductor carrying the cushion.
		Tudsbury discovered that enclosing a generator in a metallic chamber containing compressed air, or better, carbon dioxide, the insulating properties of compressed gases enabled a greatly improved effect to be obtained owing to the diminution of the leakage across the plates and from the supports.

	Pavel Imris: Optical Electrostatic Generator -- 900% Efficiency
		To demonstrate the increased efficiency of an electrical circuit utilizing the optical electrostatic generator of the present invention as well as the relationship between gas pressure and electrical efficiency, a circuit similar to that shown in Figure 1 may be used with 100 standard 40 watt, cool-white fluorescent lamps arranged in series.
		The design of the tube construction for use in the optical electrostatic generator of the type used in Figure 1 may be accomplished by means of considering the radius of the tube, the length between the electrodes in the tube and the power across the tube.
		The generator is also particularly useable in a circuit including electrostatic particle precipitation in air pollution control devices, chemical synthesis in electrical discharge systems such as ozone generators, and charging means for high voltage generators of the Van de Graff type, as well as particle accelerators.

	from the encyclopedia of free energy Electrostatic Generator 1961 United States Patent (Site not responding. Last check: 2007-11-05)
		In general, the present invention comprises an efficient electrostatic induction system capable of economical operation which may be embodied in a unit that is small in size relative to power capability.
		Still a further object of the present invention is to provide an electrostatic induction generator or motor in which energy is actively transformed to another form by the provision of reactive elements to tune the capacitive elements that are inherent in the system.
		Therefore, in general, this basic operation of the electrostatic generator is similar to an electromagnetic generator, except that the field which couples the, mechanical input energy to the electrical output energy is electrostatic rather than electromagnetic.

	The History of Electrostatic Generators
		Long before electrodynamic generators were invented, electrostatic machines and devices had their place in science.
		Although most mechanical energy needed to power an electrostatic generator is converted into heat, a fraction of the work (not a fraction of friction - got the point?) is used to generate electric potential by splitting charges.
		Electrostatic generators have their place in the history of science.

	The Van de Graaff generator
		Each generator had three independent endless-belts driven by separate motors and charged by a 10000 volts direct current source.The system was entirely enclosed in a gigantic Faraday's cage.This machine, which amazed visitors to the fair with its spark several metres long was on the front-page of many magazines, but had unfortunately a sad fate.
		The voltage is generated by an endless-belt which is in a column (or horizontal tube) with equipotential rings whose open terminals are grounded while the cylindrical collector in the middle of the column is brought to a high voltage (we imagine +) by the charges carried by the belt.
		Most of these generators can reach a voltage in the range of 10-100 kVolt and are used for demonstration purposes.(34) Among them we can mention the ingenious generator conceived by the physicist Gabriel Lorente in Madrid.(35) Lorente's machine has four parallel rotating rollers with their surfaces kept in contact by means of springs.

	Electrostatic Generators
		The Wimshurst electrostatic generator was invented in the 1880s.
		The way it works is that cemented onto each disc are a number of metal foil sectors which both generate and carry small charges of electricity.
		When you take a fluorescent bulb and bring it near a Van de Graaf generator, the charges excite the atoms inside the bulb, cause it to glow--even if the bulb is not plugged in.

	The Electrostatic Generator (Site not responding. Last check: 2007-11-05)
		An American physicist, R. Van de Graaff, developed one of the first particle accelerators in the early 1930’s, which is known as the Van de Graaff generator, electrostatic generator.
		Initially, the generator was capable of producing X-radiation in the 1 to 2 MeV range.
		Not long after the development of the Van de Graaff generator, it was determined that charged particles could be accelerated to very high speeds by driving them in a circular path.

	Powerlabs' Wimshurst electrostatic generator page!
		The Wimshurst machine was invented by J. Wimshurst in the 1880's and was the most famous electrostatic machine of the nineteenth century, before the Van De Graf generator came along.
		Electrostatic machines such as this one remained popular throughout the 19th and 20th century as a means of generating very high voltages which induction coils just couldn't stand due to their limited insulation.
		However, when this limit is reached the voltage simply becomes so high that the generator discharges itself through the disk sectors, which is bad for the insulator.

	High voltage device: Kelvin's Thunderstorm
		It is possible to build a very simple high-voltage generator which has no moving parts and is powered by the energy of falling water.
		First twist one wire from the neon bulb around one of the generator's diagonal wires, then bend the wires so other short wire from the neon bulb is very close to the other generator wire (but not touching).
		If you really cannot get your generator to work, here's a way to "cheat." Put a piece of aluminum foil on a TV screen, connect this foil to one of the inducer cans on your generator, and then turn on the TV.

	Electrostatic Machines
		The first electrostatic machine [15], was built by Otto von Guericke [16] by 1663, using a sulphur globe frictioned by hand.
		A Nairne electrostatic friction machine [7], built in 1770, consists in a glass cylinder, a friction pad in one side, and a charge collector in the other, both connected to insulated conductors.
		The Van de Graaff generator [p4][8] is an evolution of this machine, with a belt instead of the disk, and a more efficient charge collector at the top.

	Electrostatic charge generator (US4223241)
		An electrostatic charge generator for continually providing charge carriersf a given polarity in a flow of dielectric fluid.
		The charge generator comprises a coaxial tube with an inner conductor wire coaxial with a hollow, cylindrical outer conductor.
		Since the intensity of the non-uniform electric field in the conductor tube is highest near the inner conductor, the electrostatic charges of the opposite polarity as the inner conductor are removed from the dielectric fluid faster than charges of the same polarity are removed at the outer conductor.

		Obviously, the electronics are in two parts; one --- the electrostatic generator and its particular technologies of how to direct what charge where, and two --- the very unique auxiliary electromagnetic circuit of inductances, capacitances and rectification that mobilises that 'static' electricity.
		Johnson was not only a researcher of electrostatic machines but was also an innovative constructor of them, and as such was keen to try any technique that made his generators more powerful than even the specialised Wommelsdorf multi-disc condenser machines.
		At the beginning generators with special excitation were developed, which allowed to load the cells of accumulators even at low RPM at times when there are only moderate air movements.
