Fascinating demonstration of energy being wirelessly transmitted and actually causing motors, lights and different electrical objects to operate at a distance without wires. This is a winning science project as well as a very useful research demonstration.

The plasma tornado generator is an excellent demonstration of energized electrical plasma. It uses rarefied air pumped down to a vacuum of 1 mm (torr) or less and energized by a high frequency, high voltage power source. Displays range from a purple vortex shaped plasma column extending the length of the vessel to orange saucer shaped disks as pressure is even further lowered. Display will vary by pressure and the operating frequency of the power source providing a myriad of weird and bizarre plasma discharges. Outside influences such as a hand or finger will attract or repel the plasma vortexes further adding to the mystique of the device. Fluorescent or neon tube will mysteriously glow without any connections what so ever when bought near the display vessel, clearly demonstrating wireless transmission of energy.

The basic system uses our PVM12 low input voltage adjustable frequency high voltage output driver only requiring connection to one terminal of the display vessel. The other "virtual" electrode is the surrounding atmosphere with the glass walls of the container becoming the dielectric. The system is now modeled as a "lossy" capacitor. The actual rarefied air once energized by the high frequency energy becomes the loss part of the capacitor model.

The driver is short circuit protected but must be connected to the display or other suitable load. Input is 12 volts DC at 3 amps and must be earth grounded for proper operation (you can use a 12V battery for field use, or the 12DC/4AR wall adapter that is included with the PVM12). The PVM12 is described in the high frequency power supply section of our website.

The display vessel is shown as a one gallon pickle jar with a brass metal cap. The cap is shown reworked for connection to a vacuum pump and the high frequency driver for operation. The jar is available on special request fully pumped down and will provide a display that will change over time and is intended for those not having access to a vacuum pump.

This useful device is intended for those requiring clean micron-sized holes in non-metallic materials. Great for optic and laser studies requiring microfine holes. Unit as shown will go through a 1/8" thick stack of business cards in one shot.

Also great for experimenters validating dielectric and insulating integrity of certain materials. Use as a demonstration, science or specialty product.

Includes drilling stand, plasma generator and battery holder for 8 AA batteries. Product is sold without protective shielding of high voltage points. Improper contact can produce a very painful shock but will not burn or cause injury. Plasma energy is 20kv at 1/5 joule. The charger used for the plasma driller is our PBK50.

The "Plasma Audio Arc" produces loud and clear sounds through an electrical arc.

Unit includes arc intensity and volume control and operates from 115 VAC wall power. Arc is not electrically dangerous but can cause burns if contacted. It is an excellent project for the more advanced experimenter who desires to build and demonstrate an amazing and winning science project.

Simply connect to the headphone/output jack of any small radio and the sound will be created by the electrical arc in the special included acoustical chamber. There is no conventional speaker involved; the sound is created by the oscillating electric spark, which in turn vibrates the surrounding air to create sound. It's a truly magical experience to see and hear music (or any sound you put through this device) created by pure electricity.

This project will fascinate those who just do not believe that the electrical arc is actually producing this clear and crisp tone, or frustrate them as they try to explain where it's coming from!
