Solar heating: Would this work?

[Hrusai]

yes it would work. just not very efficiently, black absorbs light and doesnt reflect it, and absorbed light turns into heat, personally i'd get a bunch of lenses and fit them to focus on a single copper pipe, which would heat water very efficiently, could use it to turn turbines or to simply have hot water, nice n easy, and a good use for all the speccy kids you hated at school who are now dead cause they arent preppers xD
