Thanks, Joe blush

Ask me another on sport ... equally rubbish at that!!

Thread: Interesting??
20/05/2019 12:28:36

My original posting was looking for comments or a reasoned rebuttal (which I was totally incapable of providing) in a forum with many well qualified to do so. Pity it didn't happen!

However back to the source and this was posted :-

I also had the same idea as a kid, what is interesting is that I was in college before I finally found an answer to where the 'hidden loss' was that would keep it from working given lossless mechanical perfection, probably not exact but close enough:

Any material that can block magnetism will have induced eddy currents that will create a drag, hence the action of moving the interrupter plate requires more energy than it would if not in a magnetic field.

Even though I knew it would not work I asked various science teachers what the flaw was and none had an answer other than it would not work. I figure out the answer on my own while taking some long forgotten course.

One of the reasons that the 'inventors' of free energy devices get as far as they do is that they rely on the classic "show me why it wont work" (other than conservation of energy of course) rather than proving it will work.

As to Steorn, I believe they may have genuinely thought it was real, my theory on why it failed outside demos is that they were unknowingly tapping energy from the slightly unbalanced magnetic fields of a nearby high tension transmission line. "

From the vantage point of 'O' level General Science nearly 70 years ago, I bow to all of the above. However, I seem to remember that the world of professional Physics can prove that the bee is incapable of flight (or was it some other insect?) Just saying wink wink



Thread: Aircraft General Discussion

"flying with three aircraft on one exercise is quite rare."

Oh, how things have changed!

Nicosia mid 60s, para drop exercise, mixed Hastings and Bevs. Called downwind and got the reply "Roger, Number 12 to finals call base leg" ... and we were not 'tail end charlie' in the stream!

£1 to look ????? Is there a paywall? None from here.

The article looks at the use of rare earth magnets used (in opposition ?) to generate useful power.

Does this work?




Thread: Fake Websites

Been around for years and are in the same league as the search results for almost any item, particukarly drivers.

Standard internet rubbish!

Any thoughts??



Thread: "Screwing" a car round a corner!
03/05/2019 21:32:23

Couldn't ever afford any 'performance' metal when I was young enough to enjoy it, so had to make do with our staff transport in Bangkok - a Morris J2!! Couple Thai tarmac with total front end weight and frustrated youth (speedwise) and the results were quite spectacular! All that AND a column change to boot!

Aaaaah - days of yore!



Thread: The Chocolate Fireguard as designed by Mercedes Benz
28/04/2019 14:20:50

Observation of brakelight operating patterns plus the use/non-use of indicators is one of the more useful prompts for survival in the constant battle with the Great British Driving Idiot! I would, perhaps, be a little less than sympathetic towards anyone who complains about being 'undertaken' - that situation would indicate that the complainant was one of the ubiquitous 'middle/outside lane hogs'sad

It would be nice but naive to believe that British driving standards will in any way improve - emphasis by manufacturers on 'safety features', and officialdom on meaningless speed restrictions, will ensure yet more of the 'I don't have to think for myself - someone else will take care of it' attitude.

Personally, "Everyone else on the road is a homicidal maniac" is a mantra which has served me well, and safely, through my 83 years and million plus miles of accident-free world-wide driving.



Thread: Where's my Dykem blue gone - there's no need to read this
21/04/2019 17:48:41

Bought SWMBO a 'new' computer (more RAM /HD etc.) and wanted to transfer files from old machine. Have to do similar on my own box so bought two USB bridge Link cables. Stored them safely waiting for a blank couple of hours to do the job. Came the day ... cables nowhere to be seen - and I KNEW that they were in little plastic bags. Searched everywhere likely (and unlikely!!) and gave in and, yesterday ordered another two. Packing a parcel of goodies for a relation today and using a pile of Os&Ss to rest the package on and one bit of the pile fell onto the floor. Picked up a BLUE BOX containing a - Yes, that's right and its mate was similarly placed!!

I'm wondering if the recent medical news, that dead pig's brains can be 'activated' by some sort of intervention, might have some significance!!blushdisgust



Thread: Notre Dame
16/04/2019 18:58:17

Two possibilities??

Clean up the remains and leave as is ... like the original Coventry Cathedral.


Rebuild as was BUT ... it will only ever be a replica!!

As to available craftsmen - check on the Guedelon site - **LINK**

Genuine original skills AND French, to boot!



Thread: Arc tangent to two ellipses
12/04/2019 14:52:53

Have had a 'Flexicurve' for many years and very useful too but was offered this, some years ago. It offers a reasonable variety.img_0029a.jpg

Anyone care to hazard a guess as to its origin? Ex Weybridge chaps might be at an advantage!



Thread: What makes your bristle?
12/04/2019 14:35:45

Well then chaps - for all those who have been waiting with 'bated breath and unable to contain their excitement at the possible revelations, we have an answer ... it was the toothbrush what done it!!! Hopper pointed out the investigatory route and Sam correctly identified the cause and the culprit. The two brushes are, indeed, very slightly different in design and the culprit version allows minute quantities of 'slurry' to percolate through the body, down to the charger base, where it settles into 'yucky goo ... that is a technical term, of course!. Soooo, problem identified but not cured. Thank you to all contributors - ME Forum is magic!!smileyyes



09/04/2019 12:12:08

Hopper and Sam, thank you, Hopper, particukarly for waking up my dormant intelligence cells!!blush (especially for NOT pointing out that it was "bleeding obvious"!!) Of course that should be the first step and has now been done - results will require a week or so.

Neil - only me, SWMBO has her own.

Mark - constantly - but none have access to my bathrooms!!



08/04/2019 12:16:36

Thank you all. Sam, quite right, of course ..." better than a thousand words", so -




whereas, Upstairs -




... toothpaste, by the way, similar for both. Just doesn't make sense to me!



07/04/2019 21:34:34

Sort of on topic and the extraordinary knowledge base on this forum will, I'm sure, solve a mystery for me!

I have two Oral B rechargeable toothbrushes - one for the downstairs and one for the upstairs bathroom. I use one in the morning after my shower and one upstairs at night before bed. Useage is essentially similar, similar toothpaste, similar cleaning time, both carefully dried after use and replaced in charger. After a couple of days use, the upstairs on its base starts to collect a hardening blob of toofh paste between the brush handle and the base, the downstairs one remains consistently clean. I have just cleaned the upstairs unit for the third time in a year and it's driving me crackers!! Why the difference and, given that both are cleaned and dried after use, where is the toothpaste residue coming from????? Other than overtime by the workshop gremlin, I have no idea!!



Thread: Have your fathers habits rubbed off on you. Just for fun
30/03/2019 14:59:03

Fairly limited influence from my Dad, as for my first eight years he was fighting through India, the Middle East and then up through Italy before getting a home leave. Back again after the War but he died while I was in Aden on my first overseas tour. One cardinal rule of his which stays with me is 'Tell the truth, no matter how many problems it causes YOU, but try to take care of others" Hugely difficult, at times, and not always succeeded sad

Choochoo - have you got the Trileva manual diagram? If not I can copy and post here, if it helps?

Just come across this -

Don't understand the technical significance but VERY impressive images!
