Episode notes
Miners Are High-Performance Heaters
- Bitcoin miners convert all consumed electricity into heat, making them effectively high-performance resistive heaters with a protocol bonus.
- Tyler Stevens argues monetizing that heat decentralizes mining and repurposes power-dense ASICs into useful home heating.
From Rocket Thermal Engineer To Heat Entrepreneur
- Tyler left aerospace after a rocket launch and dove into Bitcoin heating, writing a book and founding Exergy.
- He built a Denver community, launched Bitcoin Mining Heat Reuse, and started Exergy in April to decentralize hash rate.
Comfort Heat Is A Massive Hashrate Opportunity
- Comfort heating is a massive energy segment and miners can deliver that temperature range effectively.
- Tyler estimates 1% of comfort heat converted to hash rate would add ~2 ZH, showing huge upside for distributed mining.
