Pressure Rise from Break Down of Acetone

on .

Last Thursday we added approximately 2 mL of acetone to the LENR Stick in the CTC.  Then we pulled a vacuum down to 200 mBar for about a minute to purge most of the atmospheric gasses before the turning the heat on.  We set it to run 2 hours on, one hour off.  The whole idea was to play with a recommendation from Celani a few months ago.  This wire was not showing us much, so we decided to try out the idea while we prep the multi-wire test.  

The most interesting thing we saw was the pressure building up as the acetone presumably broke down and deposited carbon on the hot wire.  The most interesting part of that happened since midnight local time when the rate of pressure rise increased, dropped, off, and then rose again.  We also saw sizable rise in the resistance up to just over 9 ohms, again.

As far as I can tell, the chemistry inside is entering different modes as it progresses.

The indicated power out has been really low, but on the last cycle with the higher pressure, it rose by about 30 to 50 mW.  Because we did not test the calorimeter at these pressures, we can't be entirely certain that this is at all meaningful.  I would much rather see some performance like ST Micro electronics and Celani both claim with whole watts of excess.

Per one suggestion from Ron B, as of this moment, we are going to just keep the power on for a while.

Other possibilities include vacuuming out the cell and pressurizing with hydrogen.  Any advice?

You could certainly see your expertise within the work you write.
The sector hopes for more passionate writers like you who are not afraid to say how
they believe. At all times go after your heart.

Still, the power supply doesn't seem to be performing exceptionally well even at 1 hz.

The sweep function was not working well at those low frequencies, so it will sit right near 1 hz all night. We had it up to 21 hz and that messed with the power control algorithm pretty good.

Is the DC polarity switching frequency slowly being increased over time at the moment, by the way? Wire resistance data suggests so to me.

Will the cell still run with the current 1 hour on-30 minutes off cycle? I think it will be more of interest to explore the polarity switching response at various frequencies while the cell is running at a steady state. I guess this will require continuous human presence, though.

Just added in a DPDT mechanical relay powered by a bench top signal generator. It will start at 0.7 hz and we'll just play from here. I don't expect anything out of this particular wire, but we'll continue to play a bit.

We are installing a shelf just above that test to make more room for equipment. I think we are bumping it around a tiny bit as we disconnect the vac pump.

@Robert Greenyer: thanks, much better now.

@Ryan Hunt: something is going on with the cell right now. Resistance has jumped up a bit in two steps, and output power has done so as well, although it still remains below significance. Reactor temperature decreased a bit. Still wiggling the stick cell inside the calorimeter ?
