Selective surface food

Somebody should test various edibles for selective surface properties. The microwave meal people could develop one-use solar box cookers with the food inside, all ready to go - just set it in the sun for the prescribed time, and hot-food is hot and the warm-food is warm. - Yossarian4010

WEll its pretty much a stub so there is still alot to do. Refrences are rpobably number one on the list! Felix 14:49, 10 May 2007 (UTC)[reply]

reflectivity aspect

the ways of rays through materials depend on the reflectivity of the matters interface , again depending on the refractive indexes of the involved phases . polished metal normally reflects infrared rays , thats why thermobottle has mirror to keep the warmth . to avoid reflection a inhomogenity in the phase transition must be intruduced by varying the refractive index . this was done already in anti-reflection coating or by gradient index optics . --Konfressor (talk) 09:34, 12 November 2020 (UTC)[reply]
