My pleasure. The thing I found when looking at the idea and researching from the cooling side is vagueness in terms of flow rates, pipe size but also I live in a humid environment and potential issues there. From my side, the design for getting round much of the issues was to run earth tubes to a cool room basement with Aircon unit to maintain constant temperature. Integrate an aluminium condenser box to reduce moisture and was considering the idea of DC vent fans to increase the flow rate with adjustable levels to augment flow. This would be low energy system redundancy to augment the heat from the miners if necessary. It’s more challenging in a hot country to utilise the heat from the miners but it’s a huge resource
