OK I made up the Disney part, but you can read the TRUTH at the link below.

Personally, I believe it more from Disney than from the Govt. Acronyms.
I was working at JPL in the early 90s when an RFP came in from one of
the US military organizations. They wanted help defining/describing
an immersive training environment. As we were reading the RFP we
all said in unison "they want a holodeck..." (Just remember, JPL was
a 30 min drive from Paramount Studios, and some of the JPL folk were
"consultants" on Trek. And various incarnations of Trek filmed at
JPL facilities). Of course when Disney (or ILM) wants to do anything,
they just need budget approval from the board or else a signed check
from a customer. When JPL wants to do anything, it's a trip to
Congress.

So who do you think is going to build a working holodeck first?

Heard something earlier this week, that Steve Jobs will become the
single largest shareholder of Disney.

In a similar vein...I remember a great comment in a book from a number
of years ago mentioning the "Military-Industrial-Entertainment Complex".
Seems like it's getting closer and closer.

You think that YOU have a problem.......

Shortly after Disney/Orlando opened about 1972, a young lady friend
and myself had the misfortune of being trapped in 'Small World' for
about an hour when the transport mechanism broke.

One solid hour of 'It's a Small World'. :-(

I'm going to Boot Camp!

You guys really need a refresher course in chemistry.


So I was trying to explain it it terms of someone who did not have a working
knowlege of chemistry.

Also, normal fuel is NOT hydroscopic. Water and fuel don't mix. That's
why you drain it out of the sumps.


You need to re-read the early posts in context. We were talking about
contrails forming behind jets. Jets burn jet fuel, which is close to
kerosene or diesel fuel. It most definitely does mix with water, and is
correctly called hydroscopic.

I do remember enough to balance a simple reaction like this. All you need
to do is tell me which hydrocarbon you want to combust! I don't know the
formula for avgas. :-)


I took a real quick look at work today - somewheres near 16 to 25H, 8
to12C. Gasoline tends to the low end of the range, Jet fuel at the high end.
Both, of course, vary so you can pretty much pick what you want.

I felt physically ill, when you mentioned this. Intensive counseling no
doubt followed, for this pour soul.

Oh, the humanity! g

Well, someone already beat me to the punch with an algebraic solution
that will handle any HC compound. :-)

Don't confuse the issue with facts! ;-)

Drop the d, add a g. I think that was I originally said, earlier. I don't
know, now.

At any rate, diesel, kerosene and jet A all absorb water, not leaving it in
the bottom of the tank, separately. Go with that concept! g
