Tellurium Silver

Tellurium Silver puts you in charge of a tiny crystal workshop. Vacuum-seal
bismuth, antimony and tellurium in the right ratio, drive a molten zone down
the ingot while impurities segregate live, patch quartz tube cracks before the
vacuum dies, grow a directional boule, slice wafers on the lattice planes and measure
the figure of merit ZT. Payout is ZT times wafer utilization, and orders for
cooling plates, power plates and sensors keep rotating with tighter specs.

Six permanent workshop upgrades all really work: a steadier zone furnace, a
wider servo drive window, stronger vacuum pumps, an X-ray orienter, a master
alloy recipe and a multi-tube puller. Coins, gear and records are saved on
device. All sound effects and music are synthesized at runtime.
