The weight is not visible in this video because it is suspended on the outside of the shed (see picture below — click to enlarge). It was only connected for about 30 minutes and the surf was so high that day that I lost one connection to the barrel. Hence, the movement of the weight was disappointingly small. This was on May 4, 2009 and was the last day of the project before I had to leave Guinea.
