Do they work? Passive Solar heaters.

This is an old video I did years ago but with home heating prices projected to rise dramatically this winter, it seems more important now. This is a two part video but I'll save you the suspense, YES they do work and yes, they are worth the time building. If you, like many of us are having a hard time with heating bills, then these can help. All you need is a fairly clear (the clearer the better) view of the southern sky and you're good to go. Good luck and stay warm this winter. For more information on DIY solar power you can click here. https://74ebd46a0ovw0u13kpuir3hkkx.ho...
