Dave,
10-4 on the typing... I type well but don't spell worth a hoot... and I
don't slow down and type well so what good is typing well in my case?
I'm very interested, I too have thought of water as a sensor media many
nights as I fall asleep (that's when I figure things out). Always seeks
level, is responsive, is natures seismo sensor already,... watch for ripples
and see everything. I'm also interested in magentic repulsion. .. back to
water. .. for the moment.
I'm very busy at the moment rerovating one of our rent houses. ..... enough
said on that subject, I'm sure. .... B U T !!! ....
Please, send me pictures of the water sensor. I'm having trouble wrapping
myself around the concept from your discription and my lack of concentration
at the moment. A picture is worth ten thousand words is some cases.
My mind keeps thinking on two concepts with water. One, ....like one of
those levels to check foundation shift. You have a cylinder with water in it
and level marks. Then you have a hose running some distance away to another
cylinder identical to the first, and another... so on. Then they add water
and check the level in each cylinder to see where the water found level at
what mark. So. this means you have a good sized or selected size reservor
of a length and narrow width to test for tilt without the ripple effect.
Well, this basic concept means that two containers some distance away with a
sensor in one will sense the slightest tilt of the crust in that dirrection,
with the size of the hose being the dampener... there are a few problems..
like delayed action. I'm sure the size/shape of the containers and
length/distance/diamenter of the tubing or pipe between the containers could
be used to work out the response. Distances between containers of sets
could be used to select frequency responses per wave lenght of crust ripple.
Compas direction could be selected to directions of special interesting
seismic activities. ... Two. .....water ripples should be a perfect
source to receive feed back of all movement in any low frequency.
Something tells me you are using these concepts... please!!! .....kick back
more information. ! ! !

Subject: Simple broadband Seismometer
I have been intrigued by the concept of using a liquid as the seismic mass
in a broadband instrument for some time. The original thought came the idea
that a damping plate was being moved through a liquid -- why not move the
liquid through the damping plate. I have also studied the MET seismometer
( I operate a CME MET vertical seismometer in my home system ) and have a
moderate understanding of its principals and the electrochemistry involved.
======= clip clip to save space =============
This is new stuff ,in operation about a month so development is still
underway. I have also been looking a vertical based on the same basic
concept,not sure about that yet but it looks possible.
On a personal note, I am a retired electrical engineer with extensive
experience in instrument design , aerospace engineering and program
management -- this is not quack stuff.
I believe I have something which could be of considerable interest to the
seismology community and am anxious to share what I have learned. I prefer
the telephone for detail discussion as I am not a good typist . I am from
the old school where a secretary did the typing so I am bit slow on the
keyboard.
I am looking forward to reading your comments and possibly telling me how
I reinvented the wheel. (If so, I haven't found that wheel).
