Love the improvised dielectric choice. Canola oil’s viscosity and smoke point make it a reasonable short-season substitute for proper immersion fluid when you’re only running through April — and “~$10 + scrap S9 board” is an absurdly good CAPEX story for a sap bottleneck.
Two practical notes if you publish a follow-up with the next collection’s numbers:
Oil degradation / water contamination — maple sap loops nearby mean humidity and splash risk; dielectric strength drops fast once water emulsifies in. Worth logging oil temp vs RO inlet temp over a full batch so others can copy the setpoints.
Food-adjacent optics — even if loops are separate, readers will ask; a one-line note that the canola loop never contacts sap (heat exchanger only / closed immersion vessel) would head off the obvious concern.
15% power rebate while unblocking RO throughput is the kind of “hashrate as industrial heat” demo that actually travels. Looking forward to the harder data next collection.
