Hi everyone

I have this one question from my optics course that has me totally stumped. It reads "Solar energy flux at Earth's position is about 1.7kW/m^2. Estimate the maximum possible population of the Earth." :surprised

I've looked through my textbook and asked a few people in my class but nobody has been able to come up with anything. Apart from one equation that I found (J=0.25n<c> where J is molecular flux, n is the particle number density and c is the mean molecular speed), I couldn't even start the question. If somebody could maybe just throw out some hints or equations, it would be greatly appreciated. Thanks
