If you have grid-tied solar, burn all excess power with hashrate instead of selling it to the utility for pennies on the dollar. Summer is a great time to mine. https://www.takemysats.com/rehash-heating

Electric heaters that don’t pay you are wasteful. I’ve been building and running hashrate heaters for a few years now. Heat your space and print sats on a standard 120v outlet. Quiet enough to run in your home. Let’s get more decentralized hashrate into the hands of plebs. Units in stock, ready to ship. https://www.takemysats.com/rehash-heating

Industrial miners retire units that still have years of life left in them. We rebuild them into space heaters you can run in your home. The greenest miner is the one that didn't get landfilled. Happy Earth Day, heatpunks 🌎

These will do between 450-850W. Configurable so you can balance power draw/noise level. Personal sweet spot is usually around 650w.
