If you did, you'd have realized that there were two different configurations; one with a solenoid wound around a conductor carrying an alternating current, and the other with a toroid surrounding the conductor. Then, the annotation should have led you to see that with the solenoid surrounding the conductor, the open-circuit output voltage and short-circuit output current from the solenoid were truly miniscule, while the same outputs from the solenoid were significant. Here's the data: SOLENOID TOROID T/S ----------+----------+------- CURRENT 4.17�A 34.1mA 818 VOLTAGE 28.81�V 11.295V 3.92e5 T/S is the ratio of the outputs, so you can see how truly disparate they are. --- >If I thought that you had enough sense to realise this, I'd say that >you were the fraud, --- What a strange thing to say! Since I obviously understood it by making it one of the cases in my experiment and showing the instrumentation used and the data obtained, how could I possibly be a fraud? You, however, parading around with your newly acquired information about how the transformer on a clamp-on ammeter is wound, as if you knew it from the beginning, do seem to fit the bill quite nicely --- >but in fact you are merely a loud-mouthed and >persistent fool. --- Well, since you do have trouble separating fact from fantasy, let's just say that you're in no position to judge...

I asked for the local water level _readings_. Before that request I had already found quite a few data sets on my own. When that data did not corroborate what they had published I asked for more of that data.

Since I can never assume how well versed the readers will be there is a lot of underlying data and explanations. A regular engineer like you and I won't read those but they are still provided. If the AGW folks want to make a case they better do the same, be open.

One can give out the data plus a link to teaching material. I often point email requesters that are more in the league of your example "my radio uses too much of the wrong current" to web sites thta teach the basics. In this day and age there is an abundance, and learning is essentially free. When I began answering requests in the late 80's and early 90's that was not the case at all, lots more work.

I just wanted some more (that I couldn't find), from areas which corroborate their claims. But anyhow, it's history, I am not interested in that particular data anymore. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
