Where do I find SELF-PERPETUATING DEVICES?

[Inventor 4U2]

I came up with a few ideas that MIGHT help the engineering and building a self-perpetuating device. One or two months ago I started this subject and found interesting input from other members. And I stated I would be working on this for the next one or two months and would come back to this site to discuss my design results. But now I can't find it. Did you remove it deliberately? If so, why would you remove an interesting subject and challenge which I have come back to share some INTERESTING characteristics of the design with others to think about and provide some input in what I am working on?
I won't mind going elsewhere with my interesting subjects to discuss and share the results of my challenging designs. I am not a bimbo that drifts around various websites for worthless discussions. And if you had left that self-perpetuating subject on your website I could have added something interesting to the subject that others WOULD WANT TO READ ABOUT.
How old are the staff members/mentors?

Gee, you should have read the rules, eh?

Overly Speculative Posts:
One of the main goals of PF is to help students learn the current status of physics as practiced by the scientific community; accordingly, Physicsforums.com strives to maintain high standards of academic integrity. There are many open questions in physics, and we welcome discussion on those subjects provided the discussion remains intellectually sound. It is against our Posting Guidelines to discuss, in the PF forums or in blogs, new or non-mainstream theories or ideas that have not been published in professional peer-reviewed journals or are not part of current professional mainstream scientific discussion. Non-mainstream or personal theories will be deleted. Unfounded challenges of mainstream science and overt crackpottery will not be tolerated anywhere on the site.

Perpetual motion and "free energy" discussions
Search PF and you will find many threads that have been closed in a number of forums. As for S&D, any claim of this nature would be reproducible and/or testable by the scientific community; hence there is no need for debate.
