energy for free | battery from nature that looks like luxury Read about the thermal mass first. The whole thing is pretty simple. I will explain in a minute and you’ll understand it. 1) Build a house with a big south facing glazing and insulate it very well. 2) Put thermal mass inside.
Let the greenhouse effect do its job. Additional Arduino and raspberry phi sensors, electronics and shutters on the glazing are required for high-end performance. That’s for managing the heat and energy transfers from one place to another, when needed.
The sun shines through the acrylic sheets on the concrete or granite walls of the inside. The free energy will accumulate within the house. The same energy will be reused in the evening. Distribution of the heat can be done with hidden water tubes. Just look at the picture below.
