There is one firm known to me DIVYA TECHNOLOGIES-Goa India, that has made the first of its kind, working model with one AC motor only. You can order a working model for Rs.98,000/- (INR)[As in August 2012] at siolcar@rediffmail.com, excluding shipping charges to your country. All planets are rotating on their own axis and revolving around the Sun. The ceiling mounted scaled working model is beautifully coloured and as seen by me it works fantastically. The space requirement is 5 ft radius ceiling without any obstructions. You can assemble the unit as a DO-IT-YOURSELF project.
It is an excellent piece of work and deserves a pat for innovative ideas by the team of developers. Well suited for schools and colleges.
