[edit] Reply to comment left on my talk page
Hi Charles,
When I said the Project SCORE required expect attention, the page was much less populated, see http://en.wikipedia.org/w/index.php?title=Project_SCORE&diff=35505342&oldid=35505311 for the revision where I listed the expert attention required. The page is now up to scratch and I feel it is safe to remove the expert attention tag. Regards Matgraham 04:40, 15 May 2007 (UTC)
Hi Charles,
The reason I deleted the 76% efficiency bit is that it's not particularly useful for a naive reader. John Kanzius is claiming that his process is a useful energy generation system. It's not. Even if it were running at 100% efficiency, it would not generate energy. It's merely a technique for liberating hydrogen, burning it and creating water again. The efficiency of the system is not central to his claim (and misleads readers into thinking that the efficiency has anything to do with anything). Greglor 13:25, 13 September 2007 (UTC)
[edit] Reply to request on artificial pacemaker talk page
"Conduction" is where a voltage applied to an electrical conductor produces a current flow. In relation to cardiac pacing the only application of conduction as a means of transfer of energy is between the implanted pacemaker generator and the heart electrodes, via metallic wires. "Induction" was historically used with pacers having a rechargeable battery. In this case the implant contained a coil of wire which could produce a voltage when influenced by a strong external alternating magnetic field. The alternating voltage induced in the coil was changed to non-alternating by means of diodes to provide a direct current inflow to charge the battery. The external "charger" also contained a coil of wire to which was applied an alternating current to produce an alternating magnetic field. By placing the charger closely over the implant there was sufficient interaction between the magnetic field of the charger and the coil of the implant to transfer energy at an efficiency of about 20% -- IOW 20% of the energy radiated by the charger coil was usefully employed, the other 80% lost in space or causing VERY minor heating of tissue. The other and current application of "induction" is where an external programming device is used to send or receive digital data from the implant. The physical principles of inductive coupling are similar to that of battery charging, ie: an alternating magnetic field is provided to induce a (pulsed) voltage at the implant receiver, or from the implant transmitter to the programming device but the objective is to couple information (small energy needed) rather than lots of energy. I hope you find this useful. RegardsGeoffrey Wickham 02:13, 26 February 2007 (UTC)
[edit] Links on Solar power satellite
Welcome to Wikipedia. We invite everyone to contribute constructively to the encyclopedia. However, the external links you added to the page Solar power satellite do not comply with our guidelines for external links. Wikipedia is not a mere directory of links; nor should it be used for advertising or promotion. Since Wikipedia uses nofollow tags, external links do not alter search engine rankings. If you feel the link should be added to the article, then please discuss it on the article's talk page before reinserting it. Please take a look at the welcome page to learn more about contributing to this encyclopedia. Thank you. Veinor (talk to me) 02:38, 9 March 2007 (UTC)
- Copied from my page:
Please do not remove Spectrolab from the Solar Power Satellite page - it is not an advert. I posted it, and I have no connection with the Spectorlab company. It is valid information to cite that the cells are ocmmercially available. Feel free to add references and citations to other data sheets if you can find them. thank you. Charles 02:39, 9 March 2007 (UTC)
I agree with Veinor. There's no need for the external link link, it has nothing to do with the article and appears to be no more than an advert for one of hundreds of solar cell companies.--Bookandcoffee 02:58, 9 March 2007 (UTC)
- The link is encyclopedically irrelevant and clearly inacceptable, not only per WP:EL but also per Wikipedia:Manual of Style (links)#Link titles. Besides, affiliation or not, the phrasing perfectly fits the "such as..." example of WP:SPAM. Femto 14:49, 9 March 2007 (UTC)
[edit] March 2007
Please stop adding inappropriate external links to Wikipedia, as you did to Solar power satellite. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Since Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you will be blocked from editing Wikipedia.

[edit] arbitration requested
I have requested arbitration on the matter Charles 05:58, 9 March 2007 (UTC)
- Just a note: the mediation cabal is not the arbitration committee. The case can be found on Wikipedia:Mediation Cabal/Cases/ solar cell vendor citation. Also, when you open a MEDCAB or other request for a third opinion, it is a very good idea to let all other involved parties know via their talkpages. The only way I know about it is that RJASE1 told me. Veinor (talk to me) 14:00, 9 March 2007 (UTC)
That is interesting because I did not even mention RJASE1 in the request. I have never tried using the arbitration system before. It seems very dysfunctional. It appears you will win, not because you are correct, and not because you understand the subject material, but simply because you have a better understanding of the byzantine process. This is unfortunate, but I have learned that is how people generaly achieve politcal power, and keep it.Charles 14:27, 9 March 2007 (UTC)
- How is Wikipedia political? And MEDCAB, the group you gave the case to, isn't the arbitration committee, which deals only with very large issues. The system is complex, I admit, but people tend to be very forgiving of new users (too forgiving, in some cases). Veinor (talk to me) 14:41, 9 March 2007 (UTC)
Actually I did leave notes for you and the other fellow on your user pages. I am very busy and do not have time to be very thorough right now. when I get some time I will consult with the Solar Cell community and ask for their opinions on who are the most notable solar cell vendors with regard to efficiency.Charles

[edit] WP:3RR
By the way, reverting content repeatedly is generally considered bad, and redoing the same edit four or more times in one day can get you blocked. More information can be found at WP:3RR. Veinor (talk to me) 14:10, 9 March 2007 (UTC)
[edit] Informal mediation
Is informal mediation still required as requested here? Please let me know. Thanks! Vassyana 13:24, 28 March 2007 (UTC)
[edit] A reply
First, let me say I am sorry you've had such a rough start. There can be a steep learning curve and sometimes new editors do not receive the welcome they sould. While I understand your concern about handles, I obviously do not agree. It makes no differance to me if someone is a Master Engineer or a secondary school electronics student, generally speaking. We should be relying on verifiable information, not credentials. Far too often, people use credentials as a bludgeoning tool in discussions, rather than using that expertise to help non-experts get a handle on the nuances of a topic. I prefer to remain under a psuedonym for a variety of reasons, including my desire for privacy. On the topic of "vicious" people, there's quite a few of us friendly sorts around and many of us are more than willing to mediate disputes and provide advice. I see you've been active at other articles since you filed the mediation request. How has your experience been on those other articles? I also see you have (in the past) expressed some confusion about the policies and guidelines. Is that still a problem for you? Either way, what did you not understand? If you never need any advice or assistance, please do not hesitate to post a message for me on my talk page. Alternatively, you can always post {{helpme}} on your talk page. Be well!!!

[edit] The request by CFRJLR
is predicated on inaccurate search terms. I recommend the use of the term 'vaseline', and consideration of the term 'hybrid'.
(What happened was some moron used vaseline (petroleum jelly), when the nitrous valve opened the whole thing promptly blew up...).WolfKeeper 01:45, 30 July 2007 (UTC)
- Vaseline should not ignite at room temperature when exposed to N2O.Charles 02:11, 30 July 2007 (UTC)

- Any ignition source will explode it. Notably, before you open the valve the pressure in the pipe leading to the chamber is 1 atmosphere of Nitrogen/oxygen atmosphere. When you open the valve the pressure of the air between the injectors and the tank suddenly goes way up- it's compressed by the ~50 bar (or whatever is in the tank) up to much higher pressures and temperatures- temperatures well above the autoignition temperature of the vaseline. The vaseline then ignites, and you then have the fire triangle, fuel and *plenty* of oxidiser as well as ignition and it all burns very, very well. That then ignites the N2O in monopropellant mode- but on the wrong side of the injectors. Kaboom.... This is called 'dieseling'. Much the same thing happens with LOX btw. WolfKeeper 02:29, 30 July 2007 (UTC)

- Hi W. You mentioned Deiseling, that gives me a clue. It sounds like somehow a high pressure condition occurred which increased the temperature to above the 300 C ignition zone. Does that sound right ? Charles 03:25, 30 July 2007 (UTC)
-

-
-
- Yup. Adiabatic compression of air to ~50 bar. It's easy to show that the adiabatic temperature of the air is then about 690C. Ignition temperature of vaseline is 290C. Boom.WolfKeeper 03:33, 30 July 2007 (UTC)

- Below 300 C, N2O is essentially non-reactive. I would like to see a more detailed accident report, can you provide a reference? Thanks.Charles 02:11, 30 July 2007 (UTC)
-
- They're amateurs. I doubt there would have been, but you may be able to find a report somewhere. Dieseling is a fairly well known problem with oxidisers though.WolfKeeper 02:29, 30 July 2007 (UTC)
[edit] Hans Ziegler
Hello -
I translated the Hans Ziegler article from the German Wiki. It has not been proofread yet, but I don't know when that will happen. Enjoy! Scbarry (talk) 05:07, 9 January 2008 (UTC)
