Philadelphia has solar-powered trash cans and artist-decorated recycling trucks. As to the "Big Belly" trash cans, they're motorized and compact trash. When they're full, they seal themselves and send out a notification to headquarters. They open like a mailbox, so they'll presumably become disgusting to touch almost immediately, and something tells me that any energy savings earned by the fewer required pickups will be outweighed by the sophistication of the cans' construction and need for upkeep.
