Thanks Kapanda, I actually thought a long time about whether or not to post this project and where to post the images. I have a lot of artist and space buddies who don't golf so they can't imagine why we'd take up room in a space station for a small golf course. I figured that other golf lovers would appreciate why I would try. It's my design so if I say there is a golf course, then there is a golf course.
Unfortunately, although I do get paid to design conceptual visualizations for space exploration, this project is more of a labour of love at this point.
Thanks for your comment broomhandle. At 500m it is the minimum size that the structure could be and still generate 1G of force while rotating no more than 2 revolutions per minute. Studies show that anything more than 2rpm could be disorientating. If it is only 80% earth gravity then the slower spin rate would be fine. Definitely, bigger would be MUCH better, not only for a more moderate spin rate, but with the added space we could do 9 holes and eventually a full 18. This winter I would like to do a 1km diameter structure and even larger after that.
