It's Pi Approximation Day again

But I can think of a better reason to bring science into today's post: researchers from UCLA have developed a new transparent solar cell that is a significant step towards giving the windows in homes and other buildings the ability to generate electricity while still being transparent. The research team describes a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light, not visible light, making the cells nearly 70% transparent to the human eye. They created the device from a photoactive plastic that generates an electrical current from infrared light. In other words, there will soon be even less reason to rely on the electric companies for what has become a basic need in our time. The PSCs are made from plastic-like materials and are lightweight and flexible, and more importantly, they can be produced in high volume at low cost. So once this invention gets off the ground, the money-hungry electric companies could soon be brought to their knees.
