We still must come up with a way to shed meltwater and sludge at the front of the nose.  This means an intenal conduit THROUGH the model, or flutings on the sides.

But, perhaps we should come up with a simple, unfluted, glass smooth model, as you suggest, and test it, in the Joe Latrell manner.  If it doesn't work, we return to the drawing board.

Joe, et al

Sounds like a good test.  I was thinking, there is/was a brand of cigar
which comes in an aluminum cylinder about 8" long and about 3/4" in
diameter. It has a screw on lid and the other end of the tube is
hemispherical the sides are straight and do not taper but it might make a
good scale model to begin with. It's large enough to work with.

You aren’t going to want any kind of flutes or
anything on the shaft of this thing. Expect it to get clogged real fast. Glass
smooth stainless 4130, or smoother is preferable. Polish it with newspaper, and
then polish it again with RainX. An old torpedo tube would work better as it

RE: PROJECT REFOCUSING

2002-10-29 Thread Joe Latrell

In this design (which is just a quick concept - I think the theory
should be tested) the 'entire' skin has the heating elements.  Imagine
just below the aluminum skin is a network of small heating elements
(nichrome wire).  This network heats the entire surface, not just the
nose.  A thin layer of water forms around the entire craft making it
slippery.  Its weight coupled with the heating will allow this type of
craft to move slowly downward.

Since our model will not be carrying any radioactive heating elements
anytime soone, the idea was to have a single wire provide power to
augment the batteries - unless of course someone wants to calculate
exactly how much dc power it would take to melt ~ 180,000 cubic inches
of water - (pi * 6) * (500' * 12) or there abouts.

Note:  I did say this is a rough sketch.  I can add more of the mental

okay, that's kinda neat, but i do have a couple
questions:

1) where's the heating element located in this model?
i assume it's in the nose somewhere, but all i see
there is "weight".  how big does the heating element
have to be to melt enough ice to allow the vehicle to
pass?  i guess this is a function of the temperature
of the ice, the temperature of the heating element,
and the speed of the vehicle, but i don't have any
idea what those variables should be.

2) what do you do with the meltwater?  i assume you
pass it though the vehicle itself using some kind of

Sorry that some of my replies seem to be "been
there done that" replies. I'm reading the posts in reverse order so
if I repeat suggestions other have made I'm sorry. The comment below suggests
we are looking for an aluminum shell. There is fairly thin walled aluminum
irrigation pipe that might be useful. I would think that inside the aluminum
shell if some PVC material (pipe mounted concentrically) might insulate the "working
components".  The thinner the outer shell the less heat is needed to
keep it warm and thus more heat will be available to melt the ice. Are we
looking at gravity propelling the device downward or some sort of propulsion
mechanism?  Just so we are looking at the same concepts is that napkin
design available to be put on the web so we can look at common ideas? Then we
can make more reasonable suggestions related to design.

I see no point to this.  What you have then is a "toy", not a

So what???  If you look at the original
rockets sent up by Goddard in 1927, there are better kit models today than what
he had then.
You have to start somewhere.  Coming up with 1001 reasons why you can't do
something is not starting.




If you are going to demonstrate "feasibility", then you need to be
realistic about the Europan environment and limitations (i.e. no
solar power) and address them.



That's why we're trying to promote this thing
without an extension cord.  We're trying to make it somewhat
self-sufficient, as we know a probe must be.
Now, I do NOT think we need to mess around with 1)  carrying a hydrobot,
2) having a video camera, 3) going to Lake Vostok, etc.
This is simply a small aluminum shell, with an internal heat source, that can
go 500' through a hunk of ice, and leave a trail of 5 transponders behind
it.  That's all.  It is not rocket science.  It IS doable, with
off-the-shelf parts.  




Re: (responses to my comments):
> First, you're the expert on finding high energy sources for very small
things.

Not really.  I simply know what nanotechnology will enable.  I am by
no means
an "expert" on what current technology allows.

I a far from an expert.  I could probably do the calculations on the
energy
requirements if the size of the probe were specified.  *But* it begs an
issue of how long you want the experiment to run.  If NASA is content to
take a decade to reach a planet, then they may be content for half-a-decade
for a probe to melt through an icecap (or longer).  That type of progress
isn't something that makes the evening news (if publicity is what you seek).



We are not talking 5 year plans, here. 
We don't have NASA's budget, or incentive to string out a project for 10
years.  This has to be done within 1 or 2 years.
It is no longer sufficient to simply sit back in an armchair and be an untested
expert.  We all know that there's plenty of theory out there
already.  What this project is about is taking a small, doable task, and
then doing it.




One can certainly find higher energy sources than Pu-238, but then one is
faced with two problems -- (a) the cost of purchasing enough of this material;
(the DOE has allocated millions of $ to purchase the Pu-238 to fuel the
remaining RTGs) and (b) the environmental impact problems.

I've devoted some thought to "fueled" alternatives and I just don't
see
any way to do it that won't involve people laughing at it as a stunt
rather than a serious scientific feasibility demonstration.  You will
have cartoons in the NY Times of somebody sitting on the surface of
the glacier riding a bicycle attached to a generator to produce the
electricity needed to power the cryobot (for 5 years).

Very hot radioisotopes would do it.  But I've mentioned the problems with
those.

Batteries definitely will *not* do it.  You could do it with
propane/gasoline
but that is going to require (a) a fuel line; (b) an oxygen line; and
(c) a way to feed those fuel lines through the ice (that may be moving and/or
refreezing).  That pr

About 250' thick should be minimum, considering that at the lower depths, the ice will be fractured, and contaminated with boulders and tree trunks.  It must have at least 250' of pristine or semi-pristine ice.
Rainier is the best hope, as it is reachable by just about everyone.

Note that even though the model is projected for a 500' test run, it can't go straight down.  It's not a drill, it's a self-contained ice submersible, capable of semi-lateral movement.

Yeah, but where else are you going to find it 3 miles deep? ;)

Bruce attached a website for a similar project.  I think ours is somewhat
different.  One serious cost cutting factor is we are not planning to go to
Antarctica.  There's plenty of local ice.
