Solar trash bins?

[an-art-worker.livejournal.com]

So I've noticed these green boxy trash bins popping up around here but until today I wasn't close to one. It looks like the entire top is a solar panel (hmm... source for solar panels.. ;-) I can't really think why a trash bin would have such a need. Is there a compactor inside? Are these tied into the grid and generating revenue? (doubtful). Can I recharge my iPod off of one?
