Once and for all: eradicating the yellow fever mosquito in Aruba
The yellow fever mosquito in South America transmits several diseases in large numbers, including the dengue virus, the yellow fever virus, chikungunya and the Zika virus. The cost of dengue on Aruba is high and many agreed on the need for these actions. It was not possible to raise the intended amount; more than half was promised, but that was all. More parties were sceptical and eventually the project was stopped.
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.
