Pretty cool design but again it seems odd that nobody is really trying to make a mining heater with a form factor similar to a traditional ceramic heater or the slightly larger radiant heater. The closest thing seems to be the Avalon Nano whose heat output and circulation are weak compared to a portable space heater. In the "almost good enough" category is the Avalon Mini and maybe the Heatbit but again, not everyone is looking for a baseboard or tower. Even among existing mining heaters, there seems to be this IMO crazy obsession with low noise. Good air flow requires trade-offs, particularly if the goal is to use this waste heat to warm the surrounding area. BTW, ceramic heaters aren't exactly whisper quiet themselves and you can find them in shops, offices and even bedrooms everywhere. And every time you see one it should serve as a painful reminder of the lost opportunity to help decentralize bitcoin mining.
