If anybody wants to see a cool artificial light that mimics natural light well take a look at coelux: [VIDEO] It is imperfect (costs too much) but it'll give a good idea of why I think heliostat/optic cable/natural light is something more people need in their lives.
Read original comment ↗In this video ( [VIDEO] ) they talk about the usage for underground buildings. It could be for underground buildings what the lift is for high buildings (eg make it practical). This was on Product Hunt a while ago: [LINK]
Read original comment ↗They are using these underground to help simulate the true daylight experience. Basically a smart led version of a traditional roof sunlight: [VIDEO]
Read original comment ↗This is not new. See this video from 2014: [VIDEO] This light is sold by [LINK] . They might also hold the patents on this technology.
