QuoteDisplay MoreFat *GlowStick* ready for pressure test... then...
[]=[lexicon]Project Dog Bone[/lexicon]=[]
Down in sunny Santa Cruz, California, Alan Goldwater has up-specced his
*GlowStick*. It has a thermocouple in the core and one on the outside.
It also has a pressure sensor.
It is coupled to HUGNetLab for data acquisition and a combination of PID, SSR and Variac for power and control.
Alan says "For the pressure sensor, I built a dedicated 5 v regulated
analog supply. Noise on the output is below the threshold of my scope,
<50 uv. I lowered the input impedance of the HUG board to 10k, which
reduced the sensor noise to ± 0.2 psi. I got the a/d calibration to
track within that limit up to 100 psi, should be good enough."
Alan adds "I have the reactor mounted and ready for initial
temp/pressure testing. It's loaded with 0.1 ml of water. I expect the
thermocouple wire plastic insulation will melt."
Sat 28th 2015,
Alan received some Carbonyl Nickel from Bob Higgins to go with the
LiAlH4 that was kindly donated by Robert Ellefson earlier in the week
(thanks Robert!). This can be run first if the Parkhomov powder is still
in transit.
============================================================
Meanwhile, up in Minnesota, Ryan has been preparing the automated power controller for the *GlowStick*
He notes:
"I just got the controller started on a 12 hour test. Just with an
empty tube and scrap of coil. It does data log. I still need to get the
PCE830 to data log"
This is the controller we have there
http://luxel.com/…/Power-Controller-II_II+-Manual-Rev2.2.pdf
This is the software that can be used to monitor it
http://www.eurotherm.com/products/controllers/itools/
The plan is to start with the Kanthal A1 heated mini-*GlowStick*
and see if that can be slowly heated up to 1200C and then see if the
power needs to be reduced to maintain the temperature as in the report
of the recent Parkhomov experiment.
The real test will be with the pair of longer *GlowStick*s,
these are heated by Inconel heating wires and will be of the same
starting resistance. One tube will have Nickel powder only. The other
will have Parkhomov powder (or initially Vale 255 if the powder has not
arrived in time) and LiAlH4.
They will be wired in series so that
the current is the same. The voltage drop across each cells will be
monitored as it may vary slightly with temperature. The control
temperature will be taken from the 'active' cell - Otherwise they will
be equivalent.
In this way, if the 'active' cell gets hotter than
it should, it will dial back the input power to both and there should
be an immediate visual difference between the two cells as the control
cell will not have the 'additional' heat from the core. There will be
the additional evidence of the temperature difference between the cells.
These things will be the same
- current
- frequency
- structure of reactors
- Nickel powder
- all times of changes to full voltage applied across the two reactors
- all ambient conditions (within reason, they'll be a little distance apart)
This will not be the same
- one will contain LiAlH4
- slight variation in power between cells as the resistance will change (will be logged)
