John Harrison is a retired physics professor who knows a lot about forces and vectors. He did some calculations about how far the 113-metre-diameter wind turbines planned for Amherst Island would routinely throw ice. He followed them up with some examples of real-world measurements that supported his calculations. The answer? 300 metres. The ice sheets thrown that far could well be lethal – like 1kg traveling from 100 to 200 km/h! Unfortunately there are many instances where the setbacks to neighboring properties or right-of-ways are far less than 300m.
Harrison’s paper is necessarily dense with numbers, so it is not an easy read for the general audience. But his conclusions can be understood by all, and they are a reason for concern.
