While we are on the subject of vending machines, the recent Vendex Japan displayed Fuji Electric’s prototype of a solar-powered machine. It is comprised of panels to supply energy to cool and heat beverages, while the mossy cover not only improves insulation, it will add a touch of green to overly grey cities. Coca-Cola is also working with Fuji to make a 100% hydro fluorocarbon-free machine that will appear this July at the G8 summit in Hokkaido.
