A Perspective On The B Type EESD - Robert Murray-Smith - Any issues?

[Jimboot]

What are you LOLing about?  And, no, I was not rude or obnoxious.  I asked him about measurements and he balked and then deleted my comments on his two clips where I raised the issue.

RMS got rude and obnoxious on LaserSaber's clip and then deleted all his comments.

So what are we looking at here?  Two people that don't want to see measurements and object to requests for measurements and don't want to know why the clip under discussion has a catastrophic error?

Two people? Now I'm not following you. Also I don't have time (nor probably the pay grade) to "play spot the error" with you. Why the guessing game?

This is a forum about research into energy and if you can't spot a glaring error in a clip like being discussed it shows how easy it is to deceive people.  It's to make people think twice about any clip they watch.

Quoting myself:

A Maxwell K2Series BCAP 2000 Farad ultracapacitor is in a can that is 10 cm long x 6 cm in diameter.  In one of your clips you claim that you made a home-brew 2000 Farad capacitor that is roughly the size of a credit card.  Let us be conservative and say that you are claiming 10X the energy density by volume with your credit card sized capacitor that you claim is 2000 Farads.

Did RMS really make a 2000 farad capacitor the size of a credit card?  Show me the data because right now I don't believe it.

oh so you're teaching? Cool. Cos it read like you were accusing someone of being dishonest.

Sorry if I offended. I don't know who it was and I suspect we may never know

He stated in his video that he wasn't trying to be super accurate. I also don't know if the part where he misstates the measurements seen on the meters was narrated at a later time, causing the misstatement. He was very liberal in his measurements saying that even if the lithium battery was twice what he calculated, his device would still blow it out the water. So his math is irrelevant to me in that his device either does as claimed or it doesn't which we'll find out soon enough it sounds like.

Another reason for letting his measurements slide is that I'm personally not to impressed with "experts" that scrutinize every detail ever since I had ex NASA people hound me on a flying project I did. I confirmed that they had in fact worked for NASA in the past. They said I couldn't build it and yet it flew a few weeks later. I am far from a genius but that's why I let the measurements in your video slide. That and me and math don't get along at all. I got into calculus where the teacher started telling us how imaginary numbers get infinitely close to 0 but never quite got there. Well "i" got infinitely close to passing the class but never quite got there

As I recall Tinmans Trifene cap was around 2600 and looked smaller than the RMS device so it seems plausible to me.

Apology accepted and Tinman is in the same boat for the capacitors as far as I am concerned.  I looked at one of his capacitor clips, I think that it may have been the clip where he claims 2600 farads.  He just makes the claim without showing any measurements, almost as if the claim was plucked out of thin air.  Where is his number coming from?  I posted on his YT clip and he didn't reply.

He mentions a certain amount of time was required to charge his capacitor or he shows it in the clip.  Let's say it was three minutes, I don't recall exactly.  I did a very rough calculation and concluded that for three minutes the average charging power provided by his bench power supply wold have to be something like 20 watts to charge the supercap to the final voltage.  Just from eyeballing the clip, I did not get a sense at all that the charging power was that high.  Of course this is all subjective on my part but I have a decent sense for things like this.

It all comes back to being honest with yourself and doing your own due diligence and making honest credible measurements on your creations for your own satisfaction.  It can be an amateur experimenter or a semi-pro or a pro, it doesn't matter.  If you are going to make your own capacitor or your own battery then the spirit of this forum is to share your results and that includes measurements done to the best of your ability, especially if you are making a claim that borders on extraordinary.

If you don't do that then there is no difference from you as an honest experimenter and someone like one of the infamous Rohner brothers.  They have both been pitching their silly "PAP engine" variations for going on 20 years and they have never done measurements that I am aware of.

Can you really make a better capacitor than a giant company that has been in the business of making capacitors for 60 years and has hundreds of millions of dollars worth of manufacturing equipment and a team of 100 design, manufacturing, and test engineers?  The short answer is yes you can.  The catch is you have to prove it to yourself and to your peers by showing credible measurements.  You can't "sleepwalk" though things like this, you have to be honest with yourself for a start.
