This is a brilliantly thought out invention Sive! It could make such a difference in cities and towns if we replaced even half the bins with these. I love that it's self powered by the rubbish it collects and solar power, and is tackling so many different environmental problems. You've thought about the practicalities, like keeping them from running people over and what to do if they get full really well too. Thanks for sending in your idea, we look forward to seeing what you invent next!
