Now this is fun news. The Finnish coffee roasting company Oy Gustav Paulig Ab has just published an innovation, which is now going to be beta-tested. The innovation is an interactive coffee mug which generates energy for its screen using some of the heat of the coffee. The mug works with the Bluetooth 4.0 Low Energy technology. This video shows what it is about, it is developed by TBWA\Helsinki.
It can be that in a sense such a coffee mug is a kind of gimmick, although you may actually use it to see news quotes or something. But I think the technology behind this has much wider potential. And it once more goes to show that there are many very innovative companies in Finland, often poppiung up from surprising corners.
