Cliff,
-What could drive home more clearly, than a bicycle generator could, the di=
fference in the amount of energy required for lighting equal-light-output C=
FLs and incandescents?
-Gotta have extra protection against breakage for the CFLs due to the small=
amount of mercury - it's probably more about the hype than the element, ne=
vertheless it would be best to be covered.
-And, don't overlook getting the best possible impedance-matching, and a lo=
w-energy-loss belt/chain.
-Can't wait to see how this one turns out.

Jerry,

I am revising my bicycle generator to work with a sequence of low voltage C=
FLs (which have been ordered). I got the idea from Brian Jones' plenary tal=
k. I am thinking the incandescents are going the way of CRTs and kids will =
find CFLs more familiar (Brian's version was comparing incandescents to LED=
s). I also made up a version of Simcha's double cone paradox.

Tappers,

* First Question:

What new experiment, demo, lab or device have you seen recently that has ca=
ught your attention?


At the summer meeting I was quite impressed when I saw or heard about these=
new things:

1. Acoustical Interferometer http://iowadoppler.com/educational.html
2. Interfacing the Nintendo Wii with Labview to do real time free body mo=
tion studies
3. The new bottom loading Flash Tube from Pasco
What have you seen lately that has impressed you?

* Second question
Does anyone know where I can get a small table top device that can do ultra=
cold atom trapping?



Thanks to all.


Best,
- Jerry
