🙂 more decentralization! - An inexpensive new kind of solar power has just been launched in Australia and it could signal the start of a groundbreaking new market for renewable energy.

Professor Paul Dastoor has created organic solar panels that can be printed using conventional printers.

By using electronic inks that are printed onto sub-millimeter thin plastic sheets, the panels can be produced for less that $10 per square meter and installed by a few people within a single work day.
