Hi Dr Stiffler,<br>
<br>
I don't believe you need credentials to publish your results to the
scientific community - particularly if the result is exciting and the
apparatus is simple enough to build and replicate. Nature doesn't lie
and the truth will out. In order to be believed you just have to
appear scrupulously honest and open in describing your methods and
results, and to be seen to have taken every possible precaution to
prevent being fooled by some unusual quirk. Scientists time is
precious and they don't like wasting it chasing down someone else's
oversights or mistakes - they have enough trouble chasing down their
own. They also don't want to do someone else's investigative work for
them - they have plenty of great ideas of their own to investigate. So
it is important to finish the job - test it until you have a definitive
result - don't present it half-baked for someone else to finish.<br>
Of course particular scientists or particular research groups very
quickly get a name for themselves depending on whether their work is
rigorous and careful, or shoddy and slapdash - and so the results of
some groups are accepted and treated with more respect than others.
But as far as I am aware the work of unknown authors would be judged on
an equal basis regardless of their qualifications or affiliations, and
simply from the information in the writeup. It is wise to have as many
friends with knowledge in the field as possible to critique it
thoroughly and try include to answers for all likely criticisms before
attempting to have it refereed for a journal.<br>

Are you talking apparent visible brightness (ie lumens) here Keith, or
real wattage? If it is wattage then I have always been under the
impression that infra-red LEDs were far more efficient than visibles,
and have always used them for position (shadow) sensors etc. But they
are still not very efficient - typically less than 50% I think. I also
believe that laser LEDs are quite a bit more efficient than normal LEDs
- but I am sorry that I have no hard data or figures and power
efficiency figures seem very hard to find.<br>
If you simply want an LED to look bright to the eye, then I believe it
is possible to flash it at some rate high enough rate to appear
steadily on to the eye but with a small duty cycle ratio. In this case
the eye responds to the *peak* brightness rather than to the average
and so appears considerably brighter than if it was run on DC with the
same average intensity. Again sadly this is only hearsay and I have no
hard data.<br>
Wikipedia has some good info on LEDs and claims "The highest efficiency
high-power white LED is claimed by Philips Lumileds Lighting Co. with a
luminous efficacy of 115 lm/W" - but lumens have never interested me!<br>

Just wondering if you really meant 1000 Farads of capacitance at 140
volts!? I'm sure you
appreciate that by conventional calculation it should take or order 3
years to charge this from a 1 W exciter (regardless of
distance and field density)?<br>
