Sounds like you've already judged my project as impossible. What good did your government agency the NOAA system for Orlando Florida in Spring 97? They did not have a warning system in place. How many died? Do not think the private sector can not come up a practical and workable system. My design may not be perfect but it will not be so difficult as you seem to think. Without going into detail for obvious reasons. I have a serious design that will save lives. What I need to know is the barometric signature of a near miss to direct hit of a tornado. If you can't or wont help me go back to you ivory tower on high. Robert Miller P.S. If I sound to harsh I'm sorry, but do you know how many times I've had a collage educated government employee tell me something can not be done? P.S.S. I also have a collage degree in electronics and digital circuits! If I can't do something I'm smart enough to figure that out for myself. Thank-you!

Hello Evan!
It was not a degree in English., and I used a spell checker extensively.
:-)
Basically my idea is for a device that will detect the tornado, but since it
can only
detect one as close as the back yard it is next to useless for the home that
has
the detector. So it broadcasts a signal to every other device within range.
I
believe I can get the production costs down to about $40.00 each maybe less.
One detector in a city is useless. So if I could seed a city with 1,000
detectors,
still rather sparse. Every device purchased would increase the
effectiveness of
the network.
If I could install 2,000 detectors in St. Louis at $100.00 each, or
$200,000.00.
The price of a single moderately priced Life Insurance policy. How much
does a
Doppler radar cost? How effectively can they detect tornado's on the
ground?
It would still not detect every tornado, especially in rural areas. However
it would
detect many as just one more tool. Hopefully cheaply enough to become as
widespread in danger areas as a simple smoke detector. In fact a smoke
detector
and or carbon monoxide detector could be incorporated into this device for
just a
few cents.
Even if I do not build this thing somebody should. I didn't think it up to
make money,
but to save lives. That's as much as I dare describe my detector in public.
The first
one will cost maybe $750,000 to produce, after that perhaps $40.00 each with
state
of the art technology.
If anybody wants to help me with this and willing to sign a non-disclosure
statement can send me an email at stargazr@alltel.net . I already have an
engineering and programming
staff, but short on backing.
Have a great day!
Robert Miller

I question if that data processing can be done for less than $100 per device. What type of RF would be involved, and how many people would be alarmed at that much RF in their neighborhood. But a more basic question is what type of data do you expect each of these 1000 devices to gather, and how often (more data means more processing). Although there may be some common "signal" that could be detected (by some sort of device), such a signal has NOT YET BEEN DESCRIBED. I may be wrong, but I can't recall any computer program that is able to model tornadogensis. Even pressure drops occur without tornadogensis.

Micro-processors have dropped in price, as well as digital signal processors and even communications chipsets. Building a foolproof sensor is not practical, anything can be fooled given the right circumstances. Is a smoke detector foolproof? yet how many lives are saved every day by smoke detectors. There are simple ways to increase the accuracy of the detector in given design constraints. Robert Miller

Unfortunately I was not part of project VORTEX (although I'm sure I would have certainly volunteered had I not been in high school at the time) :) Regarding specific data or statistics from those studies, your best bet is to either check publications such at Weather & Forecasting or the AMS Bulletin (published by the American Meteorology Society)...or contact someone at the Oklahoma University or the National Severe Storms Laboratory. I can think of several key names, but I would certainly not volunteer anyone without their permission )as they are quite busy with other research). Again, to my knowledge, direct measurements of a tornado have never been taken, although they've gotten pretty darn close. As you can tell, I'm still rather skeptical from a meteorological standpoint...and it seems that your colleagues are skeptical from an electronics and feasibility standpoint. While cost effectiveness (feasibility) would certainly be a major hinderance, Mr. Young also brings up a great point about RF. Have you thought about how are you going to fund enough detectors just to TEST its plausability? (No one will pay for an untested device). Also, where are you going to locate the sensors in an area that's densely populated and likely to get hit by a tornado? You mention you're from St. Looey. While it's certainly possible, I certainly wouldn't bet on St. Louis seeing a tornado within reasonable time to test your detector. Heck, the chance that ANY particular place gets hit by one, even in tornado alley, is extremely low. You could potentially be waiting years with 6 figures invested, only to find out that it doesn't work. Maybe I missed something, but how can you field test a seemingly random event? I guess you may have to hire some storm chase mesonet to do your work for you? Just speculating. -Evan Robert Miller wrote: > "S.
