Someone was asking me about trigering fusion with this, and i think fusion at the core of the sun is at millions °C, and at the surface you get 5500°C, so beacuse photons carry entropy and the photons of the surface is what you see, you will never be hotter than the surface of the sun, even as much rays you can concentrate. It is not a mather of how much rays you get but of pure entropy. Hotter means more entropy. You can not create more entropy in this case.
Please someone correct me if im wrong.
- p1mrx 7y agoCorrect, these temperatures are utterly useless for fusion.
- kragen 7y agoPhotons don't carry entropy, creating more entropy is easy, and hotter doesn't mean more entropy. However, you're correct that you can't reach temperatures higher than the surface of the sun by concentrating sunlight (because that would destroy some entropy), and that you need millions of degrees for an appreciable rate of fusion. Hope this helps.
