Do not use aluminum greenfield cable, and do not run any wires inside it. It is essential that the grounding water be clean, unpolluted, and circulating or moving. It must be constantly refreshed, even if only by a trickle of fresh water. A bucket sink, or bathtub can be used. The tubes should be made of galvanized steel or stainless steel, though the former is cheaper and easier to cut.
Silver is also very good, but quite expensive.
The tubes must be hollow, without dust or dirt on the interior. One end of each tube must be completely immersed into the water, and a number of tubes should be used. They may have a plastic coating on the outside. The principles of the draw tube and bucket are based upon Reich's findings that water has the capacity to strongly attract and absorb orgone energy, and that hollow metal tubes has the capacity to focus or extend the drawing influence of the water some distance outward. At one point in his research, Reich developed a device called the medical dor-buster, which was used experimentally on patients, to remove overcharge and dor from the body.
