The room grow up from 15° to 19° in 2 hours just with the sun power It work like a solar thermal air panel. but it is the room that replace the box of the panel. off course is the curtain is completly black the temp in the room will grow up proportionaly. but i must keep some light for the room that is why i choose the curtain thank you for reading try it its free heating (7\$ is the price of the curtain)

A Metallic Fringe Curtain Party Foil FOR EXAMPLE WILL DO THE JOB I effect more solar power will be reflected to the black curtain and keeping the light to go into the room if necessary a silver wire could be cutted one on two . what do you about this new idees do you have solution for improment? thank you for reading
