Future smart homes might be powered by electronics embedded in stones.

What if the counter in your kitchen served as the power source for the smart thermostats, speakers, and lighting in your house? Today, many home builders and remodelers employ natural, environmentally friendly materials like marble and granite. Researchers attached microsupercapacitors to the surface of stone tiles as a first step toward exploiting these materials to store energy. Strong and versatile equipment is used in scalable 3D power supplies.
