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.
USSR-1 on a 1933 postage stamp.Here the balloon is shown in low altitude configuration; in the stratosphere the envelope expanded into a nearly perfect sphere.. Auguste Piccard's high-altitude flights of 1930–1932 aroused interest of Soviet Air Forces and Osoaviakhim, the Soviet paramilitary training organization, as well as individual pilots, designers and flight enthusiasts.
Armstrong Hydroelectric Machine. The Armstrong effect is the physical process by which static electricity is produced by the friction of a fluid. It was first discovered in 1840 when an electrical spark resulted from water droplets being swept out by escaping steam from a boiler.
Due to Earnshaw's theorem, no static arrangement of classical electrostatic fields can be used to stably levitate a point charge. There is an equilibrium point where the two fields cancel, but it is an unstable equilibrium. By using feedback techniques it is possible to adjust the charges to achieve a quasi static levitation.

Webots is a free and open-source 3D robot simulator used in industry, education and research.. The Webots project started in 1996, initially developed by Dr. Olivier Michel at the Swiss Federal Institute of Technology in Lausanne, Switzerland and then from 1998 by Cyberbotics Ltd. as a proprietary licensed software.
The Effectiveness of Navy Electronic Warfare Systems (ENEWS) group used Builder to support the design, specification, and evaluation of EA-6B and AN/SLY-2 (AIEWS) EW systems from the conceptual through the design stages.
High-altitude balloons or stratostats are usually uncrewed balloons typically filled with helium or hydrogen and released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level. In 2013, a balloon named BS 13-08 reached a record altitude of 53.7 km (33.4 mi; 176,000 ft). [1]
