Energy Products, Projects and Devices Design SolarVille Sustainable Energy Community by SPACE10 Solarville showcases how combining solar panels with blockchain technology could make clean energy more affordable and accessible for the many. SolarVille is a fully functioning prototype, built to a 1:50 scale: some households have installed solar panels to become makers and traders of clean energy, while others automatically purchase the electricity generated in their local community. As a result, SolarVille is a cooperative micro-grid that makes a community self-sufficient.
