Daily reminder that the sun is incredibly bad at making power core power volumentric density: 276 w/m^3 core density: 150000 kg/m^3 alternative units: 1.8 mw/kg .276 w/L hello practical says a typical powered push mower might have about 1.7 KW and might weigh ball park 30 kilos, so ~60 W/kg or tens of thousands more power dense than the sun's core useful fusion is hard because we're not trying to recreate our sun, we're trying to recreate fusion environments so intense I suspect they don't show up outside of supernovas or shortly after the big bang.
