Finally a good startup again

I just found it on Gründerraum. The entire thing was student project in 2004 and they have the patents it seems and are now looking for a producer. But what did they do?

It is very simple, and has nothing to do with the Web… well not at first sight. They developed a Coaster that has a pressure sensor in it and through this sensor and wireless technology it can alert the bar that your beer is empty. :) Right on! Above that you can put some features into them of course. Let’s hope it takes off.
