Re: What-If 0145: "Fire From Moonlight"

This is not a direct response to the previous thread of conversation but a different idea entirely. Lets circumvent the problem of reflected vs radiated light that comes with moonlight, and instead, consider an even fainter light that nevertheless comes directly without mediation from objects that ...

Re: What-If 0145: "Fire From Moonlight"

Any real such box will radiate as a black body itself, and if the whole box-system is at a higher temperature than the other black body radiating upon it then it will not increase in temperature because of that other body; you've just got a hot object and a less-hot object in contact (via radiation...

Re: What-If 0145: "Fire From Moonlight"

There are 2 mistakes in this article: 1. The temperature of the surface of the moon has nothing to do with the highest temperature you get from focusing moonlight, because you're not focusing thermal radiation of the moon. Suppose we have a "brighter" moon - it reflects more light. Its tem...
