HP it's just that big a$$ Lambda 100kw BA that you found at Dayton!

Lemme get this straight... You used the Lexi to power your IECD's PSU! -- And are now surprised the latter sustained damage?!?!

I'm not preparing to read you 'the riot act'!

TNX!

But then I may have been premature!

Back atcha later! -- In the meantime, by way of elucidation of my point, kindly have a 'gander' at that thing's (the Lexi's) output on a TDO!
At risk of 'brash insensitivity' - might I suggest that what's good for Arc-PVD might reasonably be expected to be rather dubiously applied to semiconductor-based electronics?! Jeeeeeeze! Aleph!

With jaded regards
HP

 

Lemme get this straight... You used the Lexi to power your IECD's PSU! -- And are now surprised the latter sustained damage?!?!

HP How was I supposed to know! You said it would make good high current LV bench PSU so pardon me for believing you!

But then I may have been premature!

At risk of 'brash insensitivity' - might I suggest that what's good for Arc-PVD might reasonably be expected to be rather dubiously applied to semiconductor-based electronics?! Jeeeeeeze! Aleph!

HP I'm just too relived to know that's all that went wrong to mind your reprehension!

have a 'gander' at that thing's (the Lexi's) output on a TDO!

HP that's totally F'ing weird! So I watched Alexatron output using DDL for non reactive load and voltage climbs exponentially until it reaches voltage preset or current is 500A whichever comes first! Then it instantly drops back to 0v and starts again! So for low voltages (like 50v) frequency gets near 30khz! HP It's basically just current mode PWM controller (like 3844) on steroids! HP is it supposed to work like that or is that why you got it so cheap? (HP now don't you dare tell me Google is my friend cuz it's totally brain dead on subject of Lambda PSUs!) Anyhow I see why IGBT Module died cuz of 3kv ringoff at 150v setting! HP I say I should totally recap and change out pwr conditioner board on fusor HV PSU cuz if spike got to module it had to wale on movs and caps first!

HP So even though now we know why module failed I still want to test xfmr cuz it can be damaged from OC on primary and super spikes induced on secondary! So I can post inductances when I have negative PSU disassembled! HP I say litz wire is tricky cuz if strands in segment are shorting cuz of burned insulation it can be hard to know w/o varing frequency of bridge so I'll trace inductance of windings on each xfmr by sweeping from 1khz to 1mhz to make sure they track xfmr to xfmr but I still say operational test is good idea?

 

Boy...you'ze guyz sure have been quiet lately. Glad to see you on again

you'ze guyz sure have been quiet lately.

Kl7aj ain't it the truth?! It's just case of _life_ interfering with recreation!

Glad to see you on again

Tnx! I say we'll be doing tutorial again if I can master royer converter topology w/o burning my house down

 

HP How was I supposed to know! You said it would make good high current LV bench PSU

Correct! I said "would" --not-- "is"

HP I'm just too relived to know that's all that went wrong to mind your reprehension!

Indeed - 'clearance of failure analysis' is at least eight tenths of the journey!

HP is it supposed to work like that...

Indeed it is... See 'sputter deposition' / 'Arc-physical vapor deposition' for a description of the process...

is that why you got it so cheap?

In my experience prices improve as the event winds down -- I expect hauling a 600lbs 'boat anchor' on back to its 'time honored perch' falls short of 'fun' -- even in Ohio!

HP So even though now we know why module failed I still want to test xfmr cuz it can be damaged from OC on primary

Agreed! To start please examine the dielectric oil (microscopically) for pyrolysis products -- Draw a ≈ 500uL sample with a clean pipette - then replace the access panel immediately!

super spikes induced on secondary

But then...

I was watching voltage with Kerr effect field analyzer with gap set to flashover at 300kv so big margin of safety from OV damage!

---Emphasis added---
No worries! The described spark-gap will indeed have protected the secondary from OV damage!

HP I say I should totally recap and change out pwr conditioner board on fusor HV PSU cuz if spike got to module it had to wale on movs and caps first!

Agreed!

HP I say litz wire is tricky cuz if strands in segment are shorting cuz of burned insulation it can be hard to know w/o varing frequency of bridge so I'll trace inductance of windings on each xfmr by sweeping from 1khz to 1mhz to make sure they track xfmr to xfmr

Excellent plan! And kudos on your attention to 'the nature of the beast', as it were!

but I still say operational test is good idea?

IMO Such is unnecessary provided the other tests return favorable results -- That said - it's your call

As promised -Re: post #854

So I did more experimenting after I rebuilt burned out CCFL backlight inverter but it was so tolerant of wide capacitor range that it didn't help me...

--Emphasis added--
What does that tell you??? (Hint: What 'enforces' the lower primary inductance limit in any Royer design?)

Also negative channel was totally disabled by removing jumper and shorting input just to be sure!

Excellent! -- But for said precautions you'd be looking at repair of both converters!

It's just that I get the creeps running it like that when it's connected cuz if it was evacuated (which it wasn't) I'd have lethal dose from neutron flux in less than 15 seconds at that distance!

you always say neurosis on side of safety is a happy handicap

As you (seem) to realize - you're 'preaching to the choir' -- On the other hand - good though air in the chambers is for safety - D2O makes for some rather costly crocodile tears!

just remember that when JC nuked his scope and DL you just said congrats on good safety habits!

I sincerely offer you similar congratulations!

So ok! JC is undergrad and I'm PhD but like you're always saying school is for credentials and life is where real learning happens!

Disparity of academic achievement has nothing to do with it! -- Especially as your degrees are in another field! - 'Tis merely that, inasmuch as (incipient) students are rather easily discouraged, they requiring more 'nurturing' than do established scholars...

I say you're harder on me than JC cuz of our parent child relationship! Like I say that's reverse nepotism and it's not fair!

Honestly - True, true and true! -- 'Tis the way of the world! - I wouldn't change it if I could! -- Rest assured - you will understand when you have children of your own!

I can't see how I did anything wrong

Truth be told I've made far worse mistakes! -- Please! Do yourself a favor - doff the hairshirt and 'dial back' on the intensity!

So plz tell me where you got coils

They're salvaged from laminated-iron core line frequency radiography transformers -- As you've seen, they operate quite nicely at 40kHz on ferrite forms

I can't find anything like them online!

In the extremely unlikely event you require a replacement secondary, I've several NOS (dry/uninstalled) - secondaries stocked out in 'little Siberia' (i.e. shed #3) -- And YES! I've seen them as recently as last summer!

That bright spot in the sky that lights the day is proof that fusors are practical unless you think 387 septillion watts for like 9 billion years is insignificant!

--Emphasis Added--
But then stellar objects make for a cluttered instrumentation table... Moreover they tend to get 'right ratty' towards their EOL!

That said - the potential for 'gainful' operation of human-contrived 'fusion apparatus' was, perhaps, most spectacularly (albeit rather less than practically) illustrated by the Tsar Bomba -- Oh! That magic feeling...

For all that, the demands of forthright tuition compel my disclaimer that -- To date: controlled nuclear fusion remains a lossy proposition (from a physical energy standpoint)...

Best regards

In my experience prices improve as the event winds down -- I expect hauling a 600lbs 'boat anchor' on back to its 'time honored perch' falls short of 'fun' -- even in Ohio!

Explanation please, I'm from Ohio.

 

Explanation please, I'm from Ohio.

As I see it:
The 'problem' with Ohio is Cleveland -- Similarly, the 'problem' with Minnesota is St. Paul (and, more generally, the 'Twin Cities Metro Area') -- Thus it seems we've each our 'crosses to bear' - and, indeed, our blessings to count for our fortuitous non-residency in said communities!

By way atonement -- here ya go!

TTFN
HP

 

Explanation please, I'm from Ohio.

Shortbus I say HP is just jealous of Ohioans cuz they live on like doorstep of Dayton Hamvention so it's just sour grapes! Also video HP linked is ironic cuz I say Chrissie Hynde is only THING wrong abt Ohio! But I can't complain from land of Little Jerk JTJP w/o breaking walls of glass house

 

Correct! I said "would" --not-- "is"

Meaning?

I expect hauling a 600lbs 'boat anchor'

HP I say is funny you call Alexatron _Lexi_ cuz every Lexi I've ever met was short and fat so now I'm saying _Lexi_ is form taxonomy even for equipment!

Agreed! To start please examine the dielectric oil (microscopically) for pyrolysis products

HP oil is water clear with no visible particles on 600X Also what I could see of winding looked like new and oil odor is like new oil!

No worries! The described spark-gap will indeed have protected the secondary from OV damage!

Thanks HP! I'm just so rattled cuz of fusor being down I wasn't even thinking abt how I did test setup

good though air in the chambers is for safety - D2O makes for some rather costly crocodile tears!

HP ur2 funny!

Honestly - True, true and true! -- 'Tis the way of the world! - I wouldn't change it if I could! -- Rest assured - you will understand when you have children of your own!

Whatever!

They're salvaged from laminated-iron core line frequency radiography transformers -- As you've seen, they operate quite nicely at 40kHz on ferrite forms

HP I knew I saw one of those b4! Don't you have pic of one somewhere on here?

IMO Such is unnecessary provided the other tests return favorable results -- That said - it's your call

Ok if sweeps on transformers compare well I'll just change out abused passive components and install new set of modules and test it with PSU from Allegretti

But then stellar objects make for a cluttered instrumentation table...

HP not just that but if star is centered around my lab then earth is at core which for sun is like 15,500,000°K so like 27,900,000°F! Now I'm saying Al Gore would be averse!

the potential for 'gainful' operation of human-contrived 'fusion apparatus' was, perhaps, most spectacularly (albeit rather less than practically) illustrated by the Tsar Bomba -- Oh! That magic feeling...

HP It really is magic! Human magic! It's so beautiful it makes me tear up from poignancy just to think on it! It's 240 quadrillion joules in the blink of an eye from something the size of an RV! I say we've done well for a species of wimpy mutant primates! I know misanthropic ppl like to say it's just ppl finding new ways of being destructive and I say GET OVER IT! Anthropologists say fire was just weapon at first too but now it's servant in ways most ppl don't even realize! Cuz discovery of new sources of energy start with just uncontrolled energy which is always destructive but we learn how to harness it and make it work for us! So I say scuse me for luxuriating in my _human privilege_

HP If there are other tests I should be doing plz let me know ASAP cuz I want to get this done so I can sleep again!

 

Meaning?

Please recall that at the time of ownership transfer I advised you that with modification said device would function as a clean variable regulated DC supply (0V-200V to 500A) at a guaranteed line-isolation specification of 15kV -- Moreover, I made a special point of the fact that -as delivered- it was unsuitable as a general purpose PSU! Lack of attention on your part does not constitute side-stepping of 'due diligence' on mine!

HP oil is water clear with no visible particles on 600X Also what I could see of winding looked like new and oil odor is like new oil!

I suggest you closely inspect the exposed surfaces of the primary winding via the Olympus (having first made quite certain the catheter is absolutely clean and dry!) with attention to discoloration, roughening or blistering of the varnish --- But Again! Avoid contamination of the dielectric oil at all costs!

I'm just so rattled cuz of fusor being down I wasn't even thinking abt how I did test setup

I understand! - As you know, I don't do well with setbacks myself!

HP I knew I saw one of those b4! Don't you have pic of one somewhere on here?

I recall 'uping' an image of a 75kV secondary (similar form-factor albeit significantly smaller) -- FWIW I believe it was in response to the gentleman seeking advice in regards to lightweight PSU design for application to practical ion-craft? - Having only recently 'stumbled' upon said thread (in the course of reviewing past content) I should have no difficulty in finding (or, failing that, merely 're-uping') it should you wish?...

Ok if sweeps on transformers compare well I'll just change out abused passive components and install new set of modules and test it with PSU from Allegretti

Do yourself a favor and test it with its own PSU! The Allegretti is unregulated, hence adjustment of same for correct fully loaded fusor-PSU input EMF will result in an OV condition under reduced load...

HP not just that but if star is centered around my lab then earth is at core which for sun is like 15,500,000°K so like 27,900,000°F! Now I'm saying Al Gore would be averse!

As you are aware - I'm in absolute agreement with your sentiments as regards this subject! -- Tho I doubt expression of same will win us any popularity contests -- That energy doesn't take sides seems lost upon 'The Masses' -- And yes! I too believe ingrained misanthropy (for which Judeo-Christian doctrine has much to answer) plays a major role in said perspective...

HP If there are other tests I should be doing plz let me know ASAP cuz I want to get this done so I can sleep again

Test the resonance capacitor for dielectric loss (i.e. Q/DF/ESR) at its maximum rated peak potential to at least 100 kHz!

@Aleph(0) et al

Re: Resumption of the tutorial...

While you're 'making peace' with Royer conversion topology - I propose moving ahead with the following instrument construction 'micro-tutorials' -- Thoughts?

Note: @Aleph(0) As a courtesy to our readers, I have chosen to 'frame' the following as a general address, if you will -- No slight intended!

Proposed tasks

1) Complete the balanced EHT indicator construction 'micro-tutorial'
Said instrument to facilitate DC EMF measurement of floating and differential PSUs (to 100kV)

Rationale: Such instrumentation, being, as it is, essential to the 'work at hand', is both difficult to source and, in the eyes of many, prohibitively expensive...

2) Compose a GM 'survey meter' construction micro-tutorial...

Rationale: Consumer grade and other inexpensive/readily available GM-based radiometry devices/resources (e.g. consumer products, construction kits, construction projects, decommissioned military/civil defense/medical assets, etc) leave much to be desired in the ways of consistency, reliability, noise immunity and, in the case of consumer grade products, basal quality!

Prominent shortcomings of 'commonly available' GM based radiometrics include (but are not limited to) the following (order insignificant):
- Omitted or inadequate RF shielding of the GM tube with consequent liability to false counts owed to Hertizan interference (e.g. intense EMI, low level EMP, etc) -- A vital consideration as regards instruments intended for deployment in 'EHT environments'...

- Reliance upon 'telemetry' via technologies incompatible with high levels of 'ambient' EMI {e.g. WIFI, Bluetooth, etc...}

- PSU design with focus upon 'electrical economy' at the expense of 'electrical cleanliness', maximization of tube life and instrument reliability/ready serviceability...

-Omission of a GM-tube saturation detection/alert feature!

Additionally, many (in my experience, most) consumer grade products are of poor design, shoddy construction and convey a false (and dangerous) sense of 'security' via the perfidiously 'crafted' (albeit 'artfully' tacit) 'suggestion' that GM counters are suitable for dosimetry (indeed many such products incorporate dosimeter functionality/software!) -- Please be advised: GM topology (in and of itself) is unsuited to dosimetry in all cases but especially at relatively low PEs (< 50 keV) --- Under no circumstances should GM based radiometrics be relied upon for safety purposes! -- No exceptions!

While Gamascout ('reviewed' by @Aleph(0) [below]) is, indeed, especially egregious - please be advised that such is largely descriptive of consumer grade radiometrics in general...

Warning! Avoid GamaScout!
GamaScout general purpose GM counter is cheap, consumer grade dreck sold to unwary under false pretense of professional grade instrument! I bought 7 units new from three different reputable distributors and no two came close to agreement on any test source! If you are saying what did I expect for just $500 apiece I’m just saying you can do much better than GamaScout for your money! GamaScout is poorly engineered junk with telltale hook of embedded battery to make customer return unit to factory for replacement! (Rechargeable model is just as bad cuz embedded rechargeable battery eventually dies too) Honest manufacturers of quality products don’t game their customers like that! Now I’m telling you that I have owned and worked with a huge variety of portable instrumentation in my life so I can say that engineered necessity to return it to the factory for routine maintenance is well known scam of inferior quality consumer electronics! Here’s another thing, GamaScout’s labeling claims it’s accurate for xray dosimetry but it is not! It’s true that no general purpose GM counter is accurate for low PE dosimetry but the difference is GamaScout lies about it (except in fine print).

Please know that feedback from all interested/potentially interested parties is both welcome and encouraged!

Best regards
HP

 

@Aleph(0)!

Tapping fingers...

 

@Hypatia's Protege So like you know I got fusor fixed last week but I couldn't test it until today cuz Praxair had lead times cuz of prior commitments on D2 so I had to settle for lame quantity of 1800 liter cylinder So anyhow I'm happy cuz fusor totally works! So I've learned lesson of never, ever, using necessary equipment for like GA cadaver

I propose moving ahead with the following instrument construction 'micro-tutorials' -- Thoughts?

HP I don't need _peace_ with drivers until next tutorial and series doesn't need Geiger counter until later on! So I say to finish balanced volt meter and present tutorial cuz we need psychological advantage of GETTING SOMETHING DONE!

HP I'm having VPN trouble AGAIN! So I'll try to be back on here tomorrow

 

Praxair had lead times cuz of prior commitments on D2 so I had to settle for lame quantity of 1800 liter cylinder So anyhow I'm happy cuz fusor totally works!

I dunno -- Seems to me 324g (i.e. ≈ 29PJ) should keep 'Little Ivan' stocked for the nonce

So anyhow I'm happy cuz fusor totally works!

Congratulations on your successful 'expenditure' of a fortnight's work and worry to reverse the consequences of a moment's negligence -- Hey @Aleph(0) - No whining! - As you see, I refrained from 'kicking you' while you were 'down'...

So I've learned lesson of never, ever, using necessary equipment for like GA cadaver

Pleased to hear it! Tho I'm bound to ask, what was your first clue?

HP I don't need _peace_ with drivers until next tutorial and series

I respectfully disagree! The sooner you 'clear' said 'hurtle'/'block' the better all around!!! -- In my experience nothing good comes of 'layoffs' where 'attainment' is concerned! Please stay with it!

series doesn't need Geiger counter until later on!

Fair enough...

So I say to finish balanced volt meter and present tutorial

Can do!

we need psychological advantage of GETTING SOMETHING DONE!

Indeed! - To say nothing of preserving (any remaining) reader interest!

All the best
HP

 

HP I corrected embarrassing error of whole order of magnitude where I said 24 quadrillion Joules instead of 240 quadrillion Joules right here:

HP It really is magic! Human magic! It's so beautiful it makes me tear up from poignancy just to think on it! It's 24 quadrillion joules in the blink of an eye from something the size of an RV!

So plz correct it where you quoted me in post 872! Now for anyone thinking I've still got it wrong you just need to know that Tsar Bomb yield was abt 57MT not just 50MT according to misnomer So if you think that's nitpicking I say ask yourself what you can do with an extra 30 quadrillion Joules (which is abt 7MT) of energy at your command cuz then you'll see it's nothing to sneeze at!

Ha ha! HP that's perfect cuz it connects with silly jokes abt using star as lab instrument (_sunshine GO AWAY today!_) and on deeper level abt nanny state pukes like Al Gore (_he can't even run his own life I'll be damned if he'll run mine!_) so sry for like you say _exposition_ but you're always saying you're not Improv material now I say that could be changing!

Do yourself a favor and test it with its own PSU! The Allegretti is unregulated, hence adjustment of same for correct fully loaded fusor-PSU input EMF will result in an OV condition under reduced load...

HP I have to admit I just couldn't bring myself to do work of pulling LVPSU from fusor IECD chain so I used Allegretti PSU with super crowbar with threshold set for 200v! So shunt devices were redundant ignitron retrofits so each one is guaranteed to 100kA for 50ms which is totally enough margin to handle Allegretti filter Caps and after that it's just 300A which retrofit can handle continuously! So OV would just pull semiconductor fuses within 1ms of triggering! Anyhow MOVs in fusor HV PSU would save it anyway! So I say there was enough redundancy Anyhow nothing bad happened and now it's back together and working like it should!

I dunno -- Seems to me 324g (i.e. ≈ 29PJ) should keep 'Little Ivan' stocked for the nonce

HP I know you are in habit of thinking on mass in terms of energy equivalent but it can be irritating outside of relativistic context! So for example when you say 29PJ for 324g abt fusion fuel it can confuse ppl unfamiliar with fusion to thinking fusor converts all mass of D2 to energy! HP you're always saying to keep public conversation friendly for readers of all backgrounds so I say mass beyond realm of hadron rest mass should be cited as just mass!

Pleased to hear it! Tho I'm bound to ask, what was your first clue?

Congratulations on your successful 'expenditure' of a fortnight's work and worry to reverse the consequences of a moment's negligence -- Hey @Aleph(0) - No whining! - As you see, I refrained from 'kicking you' while you were 'down'...

HP! To be serious I say you owe me thanks for prioritizing tutorial to point of risking delay of my research projects by using vital resources for study of royer principles!

I respectfully disagree! The sooner you 'clear' said 'hurtle'/'block' the better all around!!! -- In my experience nothing good comes of 'layoffs' where 'attainment' is concerned! Please stay with it!

HP You're right abt that!

HP So how and when should we restart work on tutorial? Like you know I'll have a lot more time after the 14'th and I got on JC's case abt pitching in too! HP he says he's afraid of wearing out his welcome if he posts here too much cuz he's embarrassed abt damage to Tesla coil and he's totally in his words _devastated_ that he let you down again! HP now I'm going to tell you something! You're being way too patient with JC and his _lovesick_ moping! HP you cut a lot of slack to ppl who want to improve themselves through education and I say that's fine! But I say JC is carrying his lovestruck pupil routine on too long and like you say at age of mid twenties it's time he grew up! HP I think it's totally disgusting that he would have such feelings in first place let alone express them to you cuz you have been like a parent figure to him after all! So I know he's not a degenerate or like that but he needs his perspective back and that requires reality check not velvet glove! JUST SAYIN'

 

So plz correct it where you quoted me in post 872!

Done!

ask yourself what you can do with an extra 30 quadrillion Joules

8.3TWh Aye? That might cover next July's electrical usage - assuming a cool summer

HP I have to admit I just couldn't bring myself to do work of pulling LVPSU from fusor IECD chain so I used Allegretti PSU with super crowbar with threshold set for 200v!

So I say there was enough redundancy Anyhow nothing bad happened and now it's back together and working like it should!

I hear ya! - I may well have done likewise myself -- Still 'escape from victory' is far too common a 'theme' for advocation -let alone adoption- of such laxity!...

HP I know you are in habit of thinking on mass in terms of energy equivalent but it can be irritating outside of relativistic context! So for example when you say 29PJ for 324g abt fusion fuel it can confuse ppl unfamiliar with fusion to thinking fusor converts all mass of D2 to energy!

HP! To be serious I say you owe me thanks for prioritizing tutorial to point of risking delay of my research projects by using vital resources for study of royer principles!

While I am genuinely pleased your 'heart is in it' (i.e. the tutorial series) -- I cannot thank you for ill-advised decisions! -- I defer to your description of your actions and 'resolution' based upon the consequences thereof:

So I've learned lesson of never, ever, using necessary equipment for like GA cadaver

Nuff said!

HP So how and when should we restart work on tutorial? Like you know I'll have a lot more time after the 14'th

I'll get back to the EHT Indicator within the next few days thence on to linking references to expansion/glossary entries -- in the meantime please do what you can in the way of 'combing' the tutorial for errors, ambiguities and other manifestations of 'ineloquence' after you have become comfortable with resonant Royer topology-- then it's no-holds-bared beginning Feb 15 - Ok?

I got on JC's case abt pitching in too

Somehow I don't see the tutorial successfully competing with his online gaming

HP he says he's afraid of wearing out his welcome if he posts here too much

As per his profile, his last login date was Oct 20! -- He sure is making a pest of himself

he's embarrassed abt damage to Tesla coil

How did he manage that!

he's totally in his words _devastated_ that he let you down again!

Poor boy! I hope he survives!

HP now I'm going to tell you something! You're being way too patient with JC and his _lovesick_ moping!

So long as he continues to 'mind his manners' such is a non-issue that will 'sort itself out' with time -- Persistent distraction from his studies by on-line gaming, however, is quite another matter!

HP I think it's totally disgusting that he would have such feelings in first place let alone express them to you cuz you have been like a parent figure to him after all!

--Emphasis added--

Perhaps, however the fact that he is not acquainted with me from childhood renders his sentiments toward me merely 'misplaced' as opposed to 'disgusting' -- Still... the fewer (emotional) distractions from his academic work the better!

So I know he's not a degenerate or like that but he needs his perspective back and that requires reality check not velvet glove! JUST SAYIN'

Again! It is my stance that JC's real challenge is his gaming habit! -- @Jazz2C this is to advise you that we are not gossips - merely concerned friends...K?

Very best regards
HP

 

8.3TWh Aye? That might cover next July's electrical usage - assuming a cool summer

HP Better watch it cuz that's saying you're in habit of paying $913 billion per month for electricity which means silver spoon you were born with was conjoined instead of just pacifier!

HP being serious it just shows what a ripoff electrical utilities are when energy equivalent from detonation of small TND (like 7 MT TNT Eqv) in form of electricity costs almost one trillion dollars which is totally more than cost of global nuclear arsenal (which is like 70GT TNT Eqv) So I understand there's a big difference between just causing an explosion and harnessing and distributing as electrical energy cuz of conversion inefficiency and lots of overhead but I say utilities are making out like the bandits that they are!

'escape from victory'

HP Quit stealing my metaphors!

I cannot thank you for ill-advised decisions!

HP You're welcome

'll get back to the EHT Indicator within the next few days thence on to linking references to expansion/glossary entries -- in the meantime please do what you can in the way of 'combing' the tutorial for errors, ambiguities and other manifestations of 'ineloquence' after you have become comfortable with resonant Royer topology-- then it's no-holds-bared beginning Feb 15 - Ok?

HP Thanks! I'm looking forward to doing tutorial again! But no promises abt success with royer cuz all I can do is try!

How did he manage that!

HP His email said Tesla coil secondary tower was struck by piece of lumber that got launched by machine cuz he forgot to use tool he calls _riving knife_ So I don't totally understand what happened either except to say he has seven other big rooms so he doesn't need to have workshop in lab!

Again! It is my stance that JC's real challenge is his gaming habit

HP WRONG! His problem is that he is totally infatuated with you and you have blind spot and deaf ear for it like you always do with that sort of thing! HP I know cuz I talk to him on regular basis so I know what I'm saying! I also know you're not helping him by dismissing situation as trivial and sweeping it under rug!

HP Now I'm going to say this right out in public cuz there are too many IDIOTS who need to know it! Plz tell Theodora cuz she won't take proof for it that blue glow near xray tubes and IECD chambers is just cuz of ionized air NOT Cherenkov effect! HP any brain dead moron who's taken HS physics knows better but that's level she's bringing it down to by not deleting idiot posts cuz she's too stupid and lazy to think for herself! When I explain it and show her formula she just says she doesn't understand _hard science_ and says she can't moderate posts she doesn't comprehend So I posted explanations and deleted erroneous content but I say we need someone with scientific education for supermod cuz otherwise it gets just like youtube and intructables and like that! HP don't you dare give me song and dance about how she works gratis and all that cuz It's not cynical to say you get what you pay for and I say reputation is worth hassles of one more employee! cuz when we go public with site we want solid membership base instead of fringe overunity whackjobs which I say is 20% of base now!
EDIT Just so everyone knows this paragraph IS NOT ABT AAC!

HP BTW please post dose estimation formula for xray that you showed was close to accurate between 40kev and 320kev cuz then I can play with scintillator array for extrapolation of ICRP standard

 

His problem is that he is totally infatuated with you and you have blind spot and deaf ear for it like you always do with that sort of thing!

Reminds me of a childhood rhyme. HP and JC sitting in a tree, k...i... s...s...i...n...g

 

HP being serious it just shows what a ripoff electrical utilities are when energy equivalent from detonation of small TND (like 7 MT TNT Eqv) in form of electricity costs almost one trillion dollars which is totally more than cost of global nuclear arsenal (which is like 70GT TNT Eqv) So I understand there's a big difference between just causing an explosion and harnessing and distributing as electrical energy cuz of conversion inefficiency and lots of overhead but I say utilities are making out like the bandits that they are!

But then you greatly underestimate the magnitude of said 'conversion losses' and 'overhead expenses'! -- IMO electrical energy (via 'the grid') is far and away the best 'refined' energy bargain going!

But no promises abt success with royer cuz all I can do is try!

That's all I ask! -- Then too we're not talking 'black magic' - the technology works and you're not cursed! - Please rest assured we'll get to the root of your difficulties -- For 'starters', please measure the inductance of your LOPT's secondary and post same here...

HP His email said Tesla coil secondary tower was struck by piece of lumber that got launched by machine cuz he forgot to use tool he calls _riving knife_

Am I to understand he was operating a table saw in his lab!? @Jazz2C kindly explain yourself!!!

So I don't totally understand what happened either except to say he has seven other big rooms so he doesn't need to have workshop in lab!

Indeed! @Jazz2C the deal is that you are the sole occupant! -- Should I discover evidence of 'subletting', 'roommates' or otherwise communal habitation (without regard to remuneration) -- I'm not going to like it! - Meaning; If it's collectivism you want - the residence halls await!

HP
WRONG!
His problem is that he is totally infatuated with you and you have blind spot and deaf ear for it like you always do with that sort of thing! HP I know cuz I talk to him on regular basis so I know what I'm saying!

And I would say your perspective is distorted via the 'prism of youth'! -- Seems many folks your age (i.e. up to, perhaps, early 30's) tend to over esteem amative/'romantic' sentiment -- JC's difficulty is vested in his predisposition toward 'addictive' behaviour - 'on-line gaming' and, indeed, his 'infatuation' with myself being but manifestations thereof... To his credit (and in fairness to JC) he is not and never has been a substance abuser nor a gambler (for 'stakes') even so, said 'penchant' is interfering with his focus at a critical juncture (i.e his pursuit of higher education) Hey @Jazz2C -- I am uncomfortable 'talking behind your back' as it were! - Please, by all means, - have your say!

Plz tell Theodora cuz she won't take proof for it that blue glow near xray tubes and IECD chambers is just cuz of ionized air NOT Cherenkov effect!

HP any brain dead moron who's taken HS physics knows better but that's level she's bringing it down to

Yebut Theo's role is that of 'peace keeper' and member assistant not science advisor...

When I explain it and show her formula she just says she doesn't understand _hard science_ and says she can't moderate posts she doesn't comprehend

Again, her (I remind you, uncompensated) responsibilities extend no further than maintenance of community standards and assisting members with forum 'logistics'/software -- No need to deride her honesty!

cuz she's too stupid and lazy to think for herself!

Dear Aleph! Always the diplomat

So I posted explanations and deleted erroneous content

I say we need someone with scientific education...

But we have -- In the person of yourself!

HP BTW please post dose estimation formula for xray that you showed was close to accurate between 40kev and 320kev cuz then I can play with scintillator array for extrapolation of ICRP standard

--Emphasis Added--

Are you referring to the following?

RADs/s = (50EI)/Distance(cm)^2

Thus we see that, conservatively operated, even the 'umble G-256 affects a dose rate of > 3000 Rads/Min at a distance of 1 meter! -- Which being Ca 20 times that measured at the surface of Chernobyl's "Elephant's Foot"

Notice to all readers: The above 'formula' is by way of a crude (quite often low) estimate -- never to be used where health, safety or conservation of property is at issue!!!

Very best regards
