Hopefully, the technology will be developed to produce factory-sized quantities of selected scarce elements. The range of voltages currently used spans from 50 to 500 volts. Some experiments have used pulsed d.c. Written testimonies are in the form of scientific papers being submitted and printed in technical journals or technical papers delivered or scheduled to be delivered , before technical or scientific groups. Only a half-dozen of these reactors have been built.
None are available second hand.
Do not look at these machines as being able to make someone dollar rich. Look at these reactors as something that can make many people knowledge rich. Hal Fox, Editor.
