>For as good as solar panels are at converting sunlight directly into usable electricity, especially for how cheap they’re becoming, they can still only gather around 20-30% of the energy that hits them. That’s fine if you have a large roof or a huge tract of land, but if you have limited space and need to do something like heat a home, there are better options available to capture more of that energy. [Greenhill Forge] has built five solar air heating panels to test this concept, and do it much more inexpensively than commercial options.

That... Is not such a bad idea in some ways. Though, I would be worried about a leak contaminating my well at some point.

Even if you just dig down around 18-ish inches and run some pex or something that can make a huge difference. If you live somewhere cold you can do it under your garden beds to keep the soil warmer for longer to improve your growing season (small scale).

Good idea.

The rocks! The fucking rocks I got.
