Imagine: A replacement solution for power plants and energy

As John Lennon said, let's imagine:

--Imagine there is a solution for getting away from burning coal, digging and mining for it

--Imagine there is a way to get away from power plants

--Imagine there's a way to cut down on our pollution

--Imagine there's a way to stop paying a monthly price for power

--Imagine there's a way to use our current office buildings and houses windows to create the electrical power we need

--Imagine, further, that we could use the windows on our cars to do the same--to generate the electricity to run our clean, electric cars

It may be here sooner than we think:
