01
KE-TEC Battery Lab
Surplus electricity
monetised, not wasted
KE-TEC's testing cycles produce off-peak power surplus. Rather than selling back at low feed-in tariffs, this electricity routes to on-site ASIC miners - converting a depreciating byproduct into a digital revenue stream without any change to core lab operations.
02
ASIC Mining Container
90% heat recovery
at 75°C via closed loop
Liquid immersion cooling captures approximately 90% of electricity as recoverable heat, outputting hot water at 75°C via closed-loop heat exchange. This water feeds directly into the greenhouse heating system. Zero combustion. Zero fossil fuel. Validated by Canaan/Bitforest Manitoba pilot, January 2026.
03
Greenhouse / STEM Lab
Year-round cultivation
+ institutional legacy
The greenhouse maintains 25°C in the Allgau climate without any conventional heating. It doubles as a living STEM laboratory for the Weixler Institute - a closed-loop energy system children can observe and learn from daily. Infrastructure that pays for itself, and teaches at the same time.
