commercial solar water
Can Y!A users provide the chronology for the word and earliest/developing/realised instances of the ‘mirror’?
Water works great with the right background/bed, but it’s horizontal and easily rippled – just shiny surfaces sufficed at some stage, eventually giving rise to today’s mirrors with near perfect reflective qualities – but how much more specific can the answer be?

What would have driven mankind to make this kind of thing if we all looked alike? Like a commercial/industrial application, like guiding light/lasers, security for letting light but not prying eyes in – how much does a mirror tie in with other things as a practical and vital solution aside from it’s purpose in self awareness/examination…?
Any tips on making a cost-effective solar tunnel?
Your name implies you may know this:
2,000 years ago: 1Corinthians13:12: ‘We look through a glass darkly’.
No doubt mirrors (polished metal) were in use long before this, and the archaelogists will say 4,500 years ago.
