The water bottle idea would not work in the winter in cold climates because they would freeze, and ice does not freeze clear under normal circumstances. Another issue in norther climates would be the bottles sticking through the surface of the roof, they would also catch the sliding snow and thus rip the bottles out.

This invention isn't likely to take a first world country by storm. It can however, bring light to people that live in windowless shacks in places where they can't get or afford electricity.
