Solar Panel CPUs God called wafers, "dragon scales." Both photovoltaic a computer semiconductors circuits are made with silicon. What if they etch massive computers on the back-side of a solar panels? They should make the density of computer components match the density of power produced by the photovoltaics! If you do not need to compute, the solar cells export power. If the computers need extra power, the cells import power. They could include the new nonvolitile memory technology and place solid state drives distributed in the panels. They could also distribute wifi link through-out. If solar cells last for centuries, all buildings should have beautiful dragon scale siding! I would like a full wafer made into one computer! Connectivity is massively important for distributed computing. I don't understand why they don't massively connect the CPU cores on a wafer with thousand-trace-wide buses.
