We have learned in modern physics that only 4% of energy in the universe is what we know – electricity, magnetism, gravity and light, for example – and the other 96% in all creation is “dark energy” (68%) and “dark matter” (27%).

It was mid-1963 that I met John, who was working at the CIA, and we became friends. He was doing security inspections at embassies worldwide when we discussed the rising threats of audio surveillance and a need to curtail it, especially when telephones were used for eavesdropping.

As a reader of this journal, you know that you work in the largest energy-consuming sector of the U.S. manufacturing economy. You should also know some of the details and nuances of what this can mean.

My family settled in “the valley” (Shenandoah) in the 1640s. Later, the “war” devastated the entire area, to the extent that it took 90 years (1960) for the local population in northern Virginia to return to pre-war levels.

Most readers make stuff from metals or make equipment to make that stuff. So, let’s look at what and where we get some of the more unusual metals, most of which are scarce and costly.

Some readers could help the U.S. and the world by manufacturing a different kind of furnace. Let me explain.
