www.bbc.co.uk/news/magazine-23536914I'd read about this before, but at the time thought it would just collect the same amount of light as a flat clear mini-window of the same aperture. Now that i see "refraction" and "lens" mentioned, I am assuming it is working as a collector of light over a larger area than the cross sectional diameter of the bottle? Not sure if i'd be allowed to fit these in the house, but certainly good for sheds etc

Thats a really cool idea. I think I might have a go at that in the new workshop I will be putting up. Jim
