What's evidence that the Moon contains significant rhenium? A Dyson
sphere is just fantasy.

My only objection is why put the electrical energy into synthesizing,
in micro amounts when we can, simply mine the moon or Psyche -16?
Maybe when we do a Dyson Sphere around the Sun? Energy efficient so to
speak.

Interesting. I do think it is possible to reconfigure an atom, say a
carbon atom, so that it assumes electronic properties of almost any
other atom. We can in a sense synthesize Rhenium or any other rare
element.

In the November 10 2023 issue of the journal Science researchers
report on a new type of semiconductor that is one million times
faster than any found before and does so at room temperature; it's
a compound of Rhenium Chlorine and Selenium (Re6Se8Cl2), if entire
chips could be made of this substance they could make a
calculation in the femtosecond range (10^-15 of a second) instead
of the gigahertz range (10^-9 of a second) as silicon does.
Room-temperature wavelike exciton transport in a van der Waals
superatomic semiconductor
<https://www.science.org/doi/10.1126/science.adf2698>
Until now the transport of information in all semiconductors,
silicon including, is limited by scattering between electrons and
lattice quantum vibrations called "phonons" that results in the
electrons losing energy and wasting their time by bouncing around
and traveling in a very indirect route to the target. Thanks to a
new phenomenon never observed before, the electrons in Re6Se8Cl2
move directly towards their target without losing energy or time.
Unfortunately it's unlikely that chip Industry will abandon
silicon and turn to it because Rhenium is rare and expensive,
about $3000 a kilogram and only about 50 tons are refined a year,
but now that researchers know what to look for they will almost
certainly find other materials that make use of the same new
phenomenon. Of course even if a cheap material could be found it
would still be a challenge to make advanced computer chips out of
it because we couldn't make use of 50 the years of experience we
have in working with silicon so we'd be starting from scratch, but
if it's 1 million times faster it would be worth it.
