Useless solar cell machine may start improving batteries
Using a device, the ECN research center wanted to produce solar cells. The device could vaporize silicon onto solar cells, but unfortunately not with a density of the silicon that was high enough. As a result, the device lay gathering dust, until Christian Rood came across it and saw how useful the device could be for producing batteries.
Too few responses to survey
The municipality of Boxtel wanted to use a survey to find out what its residents thought about the tasks and finances of the municipality in the future. The survey that was sent out was too long and complicated, which meant that there were far too few responses to give a representative picture. The municipality is now thinking of other solutions, such as entering into discussions with residents and companies and collecting ideas via, for example, a suggestion box.
