I was thinking about the fact that windmills can operate in the wind with either vertical of horizontal axes. The axle can either be in-line with the force of the wind or across its path. The same thing applies to water-driven wheels too. Over-shot and under-shot water wheels have an axle which lies across the path of the water. Water turbines have their axle in line with the flow of water. I have from time to time attempted to design a gravity wheel which would have a vertical axis, looking somewhat like the vertical axis windmill that Bessler was building when he died. I have never been able to find a theoretical solution to this problem and yet it seems to me that it ought to be possible.
I hadn't mused upon this question for some considerable time and inevitable my thoughts turned to my current understanding of the principle which works Bessler's wheel and I realised that for the first time I could visualise a workable system using the same principle for a horizontal gravity wheel. I will not be making one soon, as I have to finish my basic model which has had to await my recovery from a secondary infection I got after my cold the other week. But it seems to me that this might be a method of discovering if anyone else's design will work. If it can be converted to work with either a horizontal axis or a vertical one then it just might be the real thing.
