Yeah, we had a lengthy discussion on the dangers of superheating water
in containers that don't lend themselves to nucleation a few months ago.
Just don't nuke it in a perfectly flawless container.

Well, presuming that your coworkers have been covering their bowls of
chili, there won't be weird stuff in it . . . .

I think you'd have a very hard time sealing the container without
suffering severe burns. The instant the infuser hits the water it's going
to start boiling all at once. It's also going to release a great deal of
steam, so the pressure the seal is going to have to hold back would be
considerable.

Better seal it fast and very tightly. Couple of ml of water turning to
several L of steam in an instant is going to generate some serious pressure.
Then you'd need to bleed off the pressure before opening.

I suppose if you were really intent on getting the temp right you could do
it in a pressure cooker of some type. Canner?

I wonder if there's a market for a "pressure pot". I wonder if I could
manufacture one. I wonder if I'll ever give up on crackpot ideas and
get a real job....

.... oh, wait. I did. Feels kind of good to be gainfully employed.

I have one of those expresso coffee makers which I never use. I did
initially use the steam boiler with the nozzle to heat cups of water
which only took seconds. I think steam can be hotter than 212f but I'm
sure the boiling tea cup temperature was only still 200f at my
altitude.

Right. And it has to be an a nonconducting case, so a stainless
steel canister with a rubber seal and a pressure release valve is out.

It's called an X-face. 40tude Dialog, my newsreader, makes it easy to
add one to messages. So does Xnews.

However, you appear to be using a Mozilla program for newsgroups, and
I don't know how to get an X-face in outgoing messages for Mozilla.

You might try playing with the following extension, as it allows for
custom headers

http://mnenhy.mozdev.org/

Also, you can use the following link to generate the header for
representing the picture you want to use.

http://www.dairiki.org/xface/

Any questions? I'll do what I can to help.

Thanks, Derek! I'm using Thunderbird, and the Mnheny extension, so I'll
play around. Thanks for the link!

You're very welcome. Have fun with it!
