[split]Photons and MASS in calculations...Split from CO2 home experiment thread.

It's not the speed of the photon but the number of photons that denote the amount of energy transported. For my first attempt it looks like Climate Realist is right.

No need for a million square kilometres, just 1 square metre will do.

Okay, surface temperature is 10C and emissivity is 0.96 this gives a radiation level of 360W/m^2 x 60 seconds x 60 minutes x 12 hours = a grand total of 15,552,000 joules.

Over the same 12 hour period our 1 square metre of water will lose 1 millimetre of surface water by evaporation or 1 kilogram of water is converted to water vapour. The figure I have at is 2,270 kJ/kg LINK so that uses 2,270,000 joules over the 12 hour period.

So radiation wins hands down. (unless my reasoning is all wrong, not unlikely)
