I happen to work in the Tech/IT/Project administration of the company I work for. Our department shares the floor with some other departments. Overall, we are quite a lot of people. And there's just one toilet on the floor. Okay, there's a second one but that the one for ladies. Most of my colleagues happen to be coffee addicts. Some are of the ( Read more... )

This year (jup, still 2012!) in February my 1KW grid tied PV system went online. Ever since I was thinking about what to do with the inverters second, unused input. Years ago I had a small Wind Turbine. A small one, it was a Rutland 910. It never produced much energy due the lack of wind and the buildings around. I sold it (for more then I've payed ( Read more... )
