I was also thinking that in that shape space could be save, they also could not roll away. I've been thinking of how dew could be captures too but don't know much about it. I did see a DIY military one on tv before but that's it. I'm not sure how much dew there is in Bali. The other good thing about this device is that it does not leave any carbon footprint. I was thinking of a modification where they could float in the sea, lake, pool, river, where the glass would touch the water and so cool down and accelerate the condensation of the water. But glass in not a good conductor of heat. But there may be some glasses more likely to conduct heat than others. I think some glass contains lead that would help conduct heat. And I don't think the lead escapes at all from the glass. It is something I am looking into.
