The solar revolution is well underway, it is hardly news anymore. However the team at Oxford PV has just merged new technology with traditional windows meaning that in the future a normal window will produce electricity, simply for doing its existing job. Even better is that the tech is on par with traditional silicon solar cells for efficiency and only getting better. If you tie this in with Elon Musks solar roof tiles, and the solar paint technology that is emerging, we are only steps away from having free electricity for the rest of our lives.
 
Which brings us one step closer to my dream of a world where everyone has a roof over their head, a house that produces its own electricity, grows its own food and collects its own water and costs nothing to own or live in.
