The AI century is short of firm power. Geothermal has always been the answer — the constraint is cost. Our mission is $30–45/MWh: geothermal electricity, around the clock, around the world.
The frontier is drilling hotter than it can see. Superhot wells — rock above 375 °C — die at transients nobody measures: across the 20-well supercritical base rate, failures are dominated by thermal stress at quench and kick-off verified. The working instrument stack stops near 200 °C. Above 375 °C there is no test standard, no qualification service, no ruler — every envelope is negotiated by phone and a vendor datasheet.
What we are building. Zemanium is the measurement and qualification layer of superhot rock. Cool-Brain profiles 450 °C-class temperatures through a passive waveguide while every active component stays cold — correcting the drift and fouling that kill downhole instruments, in place. The first witnessed 500-hour qualification record at 450 °C seeds the standard the segment grades on.
Thirty minutes for a technical review. The $2–3M pre-seed is open against a dated results schedule: chain proof in 30 days, first hot data in 90, the 500-hour record in Q1. Whichever developer wins the superhot race, the category grades on our yardstick.
