osbornes Posted March 13, 2011 Share Posted March 13, 2011 I installed one of those solatubes a couple of years ago. Absolutely love it! Quote Link to comment Share on other sites More sharing options...
dube Posted March 13, 2011 Share Posted March 13, 2011 The solartubes are quite effective, and they will actually reflect moonlight more than you might think. This soda bottle idea is awesome. Obviously not great for our climate and radical temp. changes. Not sure how ice refracts light, possibly better? I can think of a few sheds and cabin applications where this would be great, may do some experimenting this year. I'm not sure what the diameter of a 2l bottle is but I think a rubber roof flashing for a plumbing vent would be the ticket to make sure it doesn't leak. Super link Don, thanks!
