It's great when solar panels are used to produce power efficiently, but sometimes a little bit of pizazz doesn't go amiss in the world of sustainability. These tiles designed by Meidad Marzan, an industrial design student in Israel, harvest solar energy during the day and use it to create night-time OLED displays, and are a refreshing change from conventional billboards. They can also be rotated to face into the building and used as screens.

The Union bicycle makes the folded bicycle even more compact, in addition to improving the safety of its reflectors.
