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!:cool:


That's all I ask!:cool: -- Then too we're not talking 'black magic' - the technology works and you're not cursed!:rolleyes: - 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...


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


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!


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:rolleyes: -- 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!:)




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


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:rolleyes:!


Dear Aleph! Always the diplomato_O:rolleyes:



But we have:) -- In the person of yourself!:):cool:



--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"o_O:D

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
HP:)
HP TNX! I can can give proper response later cuz I've got problems now:(:rolleyes:

Tnx but I don't do Dayton, that's HP's thing:rolleyes::D So she totally shames ppl on here for being like she says _parsimonious_ for not buying new equipment then turns around and drops big $ at Hamvention for total junk on basis that it's like her annual _pilgrimage_o_O:rolleyes: My big events (which I don't call pilgrimages) are Melbourne International Film Festival and EAA Air Venture so cuz I'm aerobatic pilot w/o broken neck HP says I'm rara avis, she's so funny, NOT:rolleyes:!
So anyhow if you attend those events maybe we've met or will meet someday, who knows:cool:?

Perhaps. I am currently writing a book for ARRL on active receiving antennas. It won't be ready by Dayton, but I can at least make a few pre-publication plugs while I'm there.

So there's lots of ppl there but you can't miss HP cuz she looks EXACTLY like her avatar only without crazy costume (and axe:eek:)! So you'll know for sure if you see her so if you think you do just say _hi from Aleph_ Cuz then she'll know you're from AAC:) Also I know for sure that HP is planing to attend this year cuz she's very happy abt new location:cool:!

HP Sry I forgot to comment on this:oops:

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 I can say for sure he doesn't have any roomers or like that cuz I paid special attention for telltales during visit on Tuesday! He's just too lazy to spread out into house but he says after accident he's moving workshop do 1'st floor rec room and chemistry lab to cellar so he can rig compliant exhaust hood and like that:cool:

HP he says he wants to join in here again but he thinks you are _just tolerating him out of false sense of obligation_:rolleyes: which I say is just him seeking sympathetic attention by feeling sorry for himself:mad:! So basically he says he'll be back on here if he has direct invitation from you:rolleyes:

--Emphasis added--

@Jazz2C I suppose were all 'here' (i.e. 'immersed in physical reality') on sufferance -- but certainly not on mine!o_O:rolleyes:

So basically he says he'll be back on here if he has direct invitation from you:rolleyes:
@Jazz2C Howz about you cut the rigmarole of excuses and either 'pitch in' or or make a clear statement of your real problem? -- And once again, if you have something to say to me then kindly do so personally:rolleyes:! @Aleph(0) is a brilliant young lady but a lousy social worker/intermediary:po_O

Cool....I shall make a point to find her. :)
For ease of identification I suppose I could bring an axe along?;) - Then again maybe not! - Nothing saps the 'zest' of a holiday like 'cooling one's heels' pending 'arraignment' on weapons charges:(:D

@Aleph(0) , @Jazz2C -- And anyone who cares...
I'm presently focusing upon completion of the balanced EHT indicator project (for addition to the tutorial) -- Hence I enjoin patience - To wit: I'm not 'AWOL' - merely busy:D:cool:

NOTE: @Aleph(0) -- I feel addition of said project is appropriate at this juncture inasmuch as the readers are advised to test the LOPTs following rebuilding...

Very best regards

Hey @Aleph(0)
Thought you might find THIS interesting? -- Albeit less than imminent, the 'writing' is, most distinctly, 'on the wall'... The prodigy of Crookes, Rontgen and Coolidge is destined to 'fall' - Last as it was first; and with it, the final 'bastion' of The Age of The Electron Tube:(

Drollery aside, it really is quite poignant -- I'm old enough to recall early (commercially available) LEDs -- which being, as they were, little more than under-performing 'pilot lamps' -- laboratory curiosities at best... Little did I imagine that in three decade's time they'd offer legitimate competition to HID illumination technology!

In parallel fashion, perhaps one day you'll occasion to regale incredulous twenty-somethings with accounts of other days finding x-ray sources fashioned of glass and heavy metal -- away back when personal communication devices were carried as accessories - as opposed to implantso_O:p

No need to remind me that 'you told me so':rolleyes::D

Talk atcha in a few days!:)

Wistfully
HPo_O

Here's the post in question:

Kind Friends...

Inasmuch as this site's 'front page' often features articles in regards to evolving, novel, technologies, I feel this may be an area of interest!:)

Example of the current 'state of the art' Re: said techniques:
www.amptek.com/pdf/coolx.pdf
http://amptek.com/products/cool-x-pyroelectric-x-ray-generator/

While 'early days' indeed -- this area -and the implications thereof- are as 'huge' as they are obscure/underappreciated!

Very best regards
HP:cool:

PS -- Apologies should this post be misplaced - It's been awhile:oops:
Best regards
HP:)

HP I say _early days_ is right! They say 35kvp but practially not much beyond 10kvp

So 5 rads/Hour on contact Heh! Even itsy bitsy teeny tiny tube rings up thousands of rads/second at surface in beam path:rolleyes:!

HP I say no worries of your Last Bastion of valvedom falling anytime soon:D

Well @Aleph(0)!? - I do believe I detect something akin to 'loyalty to the old order' in your derision of the new technology!?o_O -- Something I never thought I'd hear from someone your age!:D:D:D

Very best regards
HP:)
 
Isn't 5 rads per hour slightly more than the annual limit?

[/Sarcasm]
As per prospective full body exposure (and, via conflation of REMs with Rads, [which being appropriate given the PE range and source involved]) -- Yes - by a factor 8,760 -- All of which being a 'neat trick' with the device in question... But seriously! Prolonged or repeated exposure to even so feeble a source would be both unhealthy and rather foolish....

Best regards
HP:)

PS - Sarcasm noted;)
