One of the biggest hindrances that prevents solar energy from being more ubiquitous is the exhorbitant cost, but MIT grad Miles Barr has found a way to make solar energy cells cheaply and affordably. How? By printing them on paper. Using a unique process called Chemical Vapour Distribution, Barr is making it possible to print solar cells on every surface imaginable, effectively turning everything around us in a conduit for alternative energy. Barr has also started his own company fittingly named “Ubiquitous Energy,” that has raised over $1 million in funding already.
