Yes, I have seen this article, more than once.The article is ancient, stupidly implemented and does not relate to a telescope mirror in the trues sense, yet it's posted here for me to be ''informed'' that the Mylar mirror idea is a waste of time!
What the hell does one expect when they ''crudely'' stretch film on bike rims without any consideration towards evenness or optical flatness as a first and most important pre-requisite and then expect perfect optical performance while the frame bends under vacuum forces.............c'mon everyone..............get a grip on this.
I've said it before.............LOOK AT THE PATENT..............is it a couple of bike rims with metalised glad wrap?????
It's a complex system designed to control every square mm of that Mylar and it's subsequent tensioning and contact with the purposely designed wide rim when a vacuum is applied.
Is everyone ignoring the details or just not bothering?
If we're going to talk about audio and microphones, I'm an expert on that with direct experience as a recording engineer .
Microphones do have ''thin'' membranes............the Wadell mirror is 100microns.............one hundred + times thicker than an electret microphone
.............le t's leave that one for ''James''.
If we consider vibrations in a telescope, I have seen some of the very best wobble like jelly in a slight breeze or nearby foot steps at moderate to high power(Perth Observatory)
I'm not defending the Wadell mirror or his methods and am no way affiliated with him apart from email contact and some documentation that I am waiting upon.
I would have thought that this thread would be of benefit to my fellow ATM's, even if it was just considered as a possibility until further documentation came to light.
The result has been the opposite with critics who insist that it's impossible when they know the product is in existance and in use.
Irrespective if the application is relevant for telescopes or not, my expectation was to at least generate some interest and ''positive'' input towards the subject and not just ''been there done that''......... when you know quite well that you did not even get close to what's required as a start to possible success.
With all due respect to those who read the thread with some interest but did not contribute post wise, I personally will stop posting on this subject from here on.
Happy observing
