Boston has got the newest and the more energy efficient, third generation version of the solar trash compactor, The BigBelly to keep-away from the problem of overstuffed public trash cans. The self-compacting, solar-powered trashcan developed by a Jamaica Plain inventor is powered by photoelectric panels, which supply power to motor-driven compactors inside. The green-colored boxy trashcan can hold some 150 gallons of trash, which is about five times more than a standard city receptacle and it even smells less. The solar-trashcan costs $4,300.
