What happens if the device shakes itself apart while rotating? This is not something that I would like to have in my backyard without any secure way of preventing parts of it from hitting people or my house (perhaps some kind of net). If I was living in a rural area away from people and had a lot of space I would set one or more up as an experiment ~150 m fra the house.
