the high price of Wollaston wire

[eub]

These folks sell Wollaston wire, platinum in nickel. One-micron wire costs $1556 per meter, or $458 per 10 cm. We're not even going to talk about the 0.6-micron wire.

You make thermophones. I'm not totally sure what a thermophone is.

Then from www.thefreedictionary/com/thermophone :

"Ther´mo`phone
n. 1. A portable form of telethermometer, using a telephone in connection with a differential thermometer.
2. A telephone involving heat effects, as changes in temperature (hence in length) due to pulsations of the line current in a fine wire connected with the receiver diaphragm."

I don't really get what that means though. A telephone like something that communicates sound? Not necessarily a telephone to talk over? It's some kind of weirdo musical instrument?
