Trying to find super cheap way to collect solar

[triffid]

I could not believe that last night night I found in one of my text books a design on how to build a solar hot water heater using cardboard as a frame
and newspapers as bedding.I was so excited.While its a student's experiment it could be scaled up to put on a house.Pay attention to this:
Materials;Shoe box painted black on the inside and filled with newspaper(crumpled up) painted black.rubber or plastic tubing,1-mm diameter and about 1 m in length.Plastic wrap. The rest of the materials listed were there to help the students do their experiments.But the point is that someone used CARDBOARD TO HEAT WATER WITH SOLAR POWER.Triffid

I confess,I smell a business here.Making solar hot water heaters out of mostly cardboard and using wooden box frames with glass windows to protect them from rain on a person's roof.I just couldn't see before last night.Triffid

As noted higher in the thread:

Already being done cheaply and effectively.

Thanks,tech student,I think new ways of capturing the the sun's energy is always desired.We (the human race) are energy starving in the midst of plenty(solar power).Triffid

Yes, we are starving, and in various ways.....and there is a critical, sobering reason for this.
