I managed to find an absolutely AWESOME example of how entirely new technologies are popping up out of the solar industry. Below is a link to a small article in Egypt, about a small team of people who have invented a 3D-Printing machine that melts sand into whatever desired shape.
This guy is going to change everything. 3D printing has been steadily rising in popularity as it can be adapted to an incredible amount of products, but no one and I mean NO ONE has yet been able to make the whole process renewable in terms of electricity and materials. Until this guy…I’m eager to see what else he will develop.
