The runs with the glass upper surface duplicated the conditions with the copper plate and the corresponding photographs were correlated. A bill based on the weight of the copper (and later zinc), and hence the amount of electricity used, was sent to the household. Elemental analyses of this deteriorated wood showed high levels of copper, chromium, iron, and lead, suggesting that a caustic chemical spill had occurred. Indeed, all these profiles were close together due to the high thermal conductivity of copper. The electrical pulses are directed through a copper coil, shaped in a figure eight, which is placed against the human's scalp.

Considerable amounts of rubbish remained at the soil surface, including crushed lead batteries, copper artefacts, used food cans, and building materials. In the first three years of the mint's existence only $453,511 was issued in gold, silver and copper coin. A thin vacuum gap separates the cobalt and copper foils from each other and thus electrons are held back by self-generated fields. In the case where the stainless steel cathode is replaced by a copper one, the operating voltage for all gases used decreases by 20 -30%. These examples are from corpora and from sources on the web.
