I mean power per unit area 06:36 < xentrac> irradiance 06:37 < chris_99> heh i just found spectral irradiance too 06:37 < xentrac> yeah, I just mean total irradiance 06:38 < xentrac> so even if your microwave emitter is 10× more efficient than a laser, which should be easy to arrange, you're going to suffer from things being unwieldy 06:38 < gnusha>
