“We should live as if we were in public view, and think as if someone could peer into our inmost souls… Limit yourself to what is necessary, and be content with a simple life, so that you may act with purpose and not be swayed by the opinions of others.”
Seneca
The picture above is a watch to which I removed the dial and replaced it with a cross section of a superconducting wire. Once fully processed, such wire will be about 1 mm in diameter and have exactly the shape you see above (but about 30 times smaller).
This wire design will be part of the ITER fusion reactor.
The website background picture is a conductor made of thousands of superconducting wires, twisted and placed inside a stainless steel tube. Kilometers of this conductor will be transporting about 60,000 amps of current and producing a magnetic field of about 12 tesla (huge!) in order to help drive and control the plasma reaction in the ITER machine.
