Rossi biography's and other stuff....new...5 sep...

Looks like there is a race starting...other companies trying to be the
first...

He needs something new and well defined to patent and sell, he can't just
say he repeated a 100 year old process and magically got different results.

You may be right...if you read through all the things on the page I
linked to it say he is delaying the demonstration in Oct...

However I still have my fingers crossed...as I have seen to many times
when a scheduled new thing was delayed...always something seems to
happen unexpected....

I have a friend in Belgium who seems to be having a love affair with the
Arduino. :) You might also find that interesting.

I use Arduino too, nice board, c+ programming, lots of open source and
intefaces to Win, X, or Mac.

I'm going to test without water at all, and my current plan (subject to
changes) is to try to measure the temperature /inside/ the reaction
chamber and at its outside surface.

The initial goal is to determine whether or not the reaction can become
self-sustaining. If I can't get it to do that, then the game is over. If
it will self-sustain, then it can be thrown into an insulated tub and we
can measure the rate of heat increase up to the boiling point to get a
reasonable handle on heat production.

I kinda like how you tie together the two technology extremes. :)

If it was that easy Marie Curie or Fritz Haber should have encountered it a
century ago. Chemistry as an observational (versus predictive or
theoretical) science was quite mature by 1900. Either Rossi purposely or
accidentally did something different from everyone else, or he is fraudulent
or misled by poor experimental technique. (decision matrix)

I built temperature-controlled test chambers for semiconductor production
testing and saw up close how difficult accurate temperature and heat
transfer measurements can be. I never got the right answers from these
seemingly simple things:
http://www.chem.hope.edu/~polik/Chem345-2000/bombcalorimetry.htm


I fit my methods to the desired results. When the stew pot temperature jumps
from ~60C to ~90C it needs attention. The real intent is to keep the stove
burning hot enough that the chimney doesn't smoke. A thermostatic air inlet
control wouldn't be enough to compensate for wood size and dryness or the
draft variation from outdoor temperature and wind. I have a tapered gauge to
set the opening and a mental table of adjustments.

These thermocouple panel jacks fit the snap-in entertainment center wall
plates Radio Shack sells with only a little whittling.

I have solar panel, 2x thermocouple, TV antenna and phone outlets in one,
all leading to the kitchen computer desk.

I understand how that works - but early in the game (before Windows
arrived on the scene) I made the decision to specialize in "mission
critical" systems where failures would result in loss of life or incur
costs larger than some national economies. Firms who insisted on Windows
platforms automatically disqualified themselves and their projects from
any possibility of success in the mission-critical category, and I've
never had any interest in producing unreliable stuff.

I saw the same thing in high-performance hardware. The user console might be
Microsoft (or Apple) but the central processor was more likely a DSP running
RTOS. A standout exception was the HP Infinium oscilloscope that used Win98.
They're probably available, but unix folk tend to be a lot more interested
in reliability of result than in the cheapest possible solution, which is
exactly what winmodems are.

That's my home setup, though, recycled office machines saved from the
scrapyard. I bought a Broadband2Go prepaid air card to get them on line to
download large programs and updates.
On your previous post: If you really want to learn C, I'll be glad to
help - but I think e-mail would work better than alt.energy.homepower
Since you've written both assembly code and Pascal, C should be easy and
fun for you.
Morris Dovey

Scientific/engineering computing is very different from business
applications, much more intensive and less extensive. I'm looking for a
little guidance to select a development system optimized for driving and
debugging attached hardware rather than writing Web browsers, networking or
database management. QBasic would be fine if it was updated for modern
hardware. I have Visual Basic 5 that I bought on a work+home license on the
drive of a crashed laptop, and the Visual Studio 6 free demo version. The
trouble with them is that they and Windows doesn't allow me unobstructed
access to the I/O ports. That's why I switched from VB5 to DOS + QB and use
them like a massive self-contained microcomputer development system, with
the three LPT1 registers providing the programmable digital I/O pins, and
external A/D converters on the serial ports.

Did you notice the comment at the end of this article?
http://www.chem.hope.edu/~polik/Chem345-2000/bombcalorimetry.htm
"Calorimeter design is very tricky, especially for processes involving very
small energy changes, e.g., protein folding, or energy changes on top of a
large background, e.g., excess heat from "cold fusion". Heat leaks must be
minimized, and all other heat generating processes must be accounted for."

The cheap substitute for a Dewar is a wide-mouth vacuum Thermos bottle.

I spent most of the evening designing and coding software to control the
reactor's heater using a single-bit output to switch a solid state relay.
Morris Dovey

I think I have a quick and simple way to tell if it produces excess energy.

Adjust the heater power supply voltage so that the temperature won't exceed
whatever maximum limit you've set with the power left on constantly, ie so
it rises logarithmically toward a safe asymptote. The RMS power input should
be the same as when it's cycling at that temperature, but constant to smooth
out the curve and reveal fine detail.

Fill the reactor with helium and record the temperature vs time curve.
Helium approximates hydrogen's high thermal conductivity but is inert, and
easy to get in balloons

Put in hydrogen and look for deviations from the helium curve.

I wrote a particularly bad explanation that time. Look for any deviation
from a smooth curve:
