HUG powder test cells [UPDATE #5 - Testing Higgins' Powder]

Geschrieben von Ryan Hunt am 06. Juli 2014.

Much has been going on in Minnesota and with everyone else busy, we are trying to find ways of getting more information to you all faster.

Two cells are being constructed into isothermal boxes for testing the array of nano and nano-micrometric powders of various types we have access to from Brian Ahern, QSI and Bob Higgins.

The development work has been captured into Evernote as this is really convenient to do for the team - in this case Malachi and Ryan - however, Alan Goldwater and Mathieu are starting to use it also, so we had to find a way of getting this information streamed onto the QuantumHeat.org site. We have been testing Zapier.com and cloudhq.net and are using both - one is making PDFs of posts and the other is making links to the Evernotes in a Google sheet.

Let us know what you think.

UPDATE #1 - Cool videos

Disassembling the powder cell

Swapping the micro Ni powder for the Quantum Sphere Inc nano Ni.

UPDATE #2 - Brian Ahern powder IN!

After a VERY generous donation of time, money and resources by Nikita Alexandrov of Permanetix Corporation, Last week, we received back the milled Zirconium Oxide / Palladium / Nickel matrix powder to the milling specification of Dr. Brian S. Ahern. A big thank you to Nikita.

About a third of this powder was today, 15th August, placed into the powder cell. A further third or so is expected to go into the "Sparky Cell" that another great volunteer - Skip has been working so hard on of late.

Check out the recent links to Evernote above for the details.

Keep watching this space!

UPDATE #3 - Loading!

UPDATE #4 - Calculated excess rising?

Calculated excess heat above calibration consistently trending upwards as Dr Brian Ahern's powder continues to absorb Hydrogen.

Ryan has made a live google spreadsheet that regularly updates showing calibration based calculations of excess heat.

UPDATE #5 - Testing Higgins' Powder, Dec 15, 2014

Powder from Bob Higgins has been installed into the cell and the cell calibration has been checked. The calibration was right on from last time, still. Nice. What happens next? Bob Higgins suggested this:

I saw results after heating in a vacuum over a weekend - a much lesser vacuum than you can achieve (~1E-1 torr). Heat to about 250ºC in vacuum. Let cool. Then apply about 80PSI of H2 and heat to about 300ºC. After about 280ºC you may see excess heat. Try turning off the heat and see which way the temperature goes.

Without the H2, it is a good dummy experiment to see how the temperature of your cell responds to turning on/off the heat - particularly turning off the heat. There will be only a small delay and the temperature should start going down. Look for changes in that when you turn off the heat with the H2 applied.

Base don this, our initial plan looks like this:

Step 1 - Degas - Heat up to 250C under dynamic vacuum. We will try first with the valve closed to the cell and see if we get a pulse of gas out when we open it at 250C. (about 2.4 watts input power)

Step 2 -Cool down from 250C. (capture cool down curve for comparison)

Heat to 300, cool down, again. (3.2W) (another calibration comparison)

Heat to 350, cool down (4W)

Step 3 - Add 80psi H2, close the valve.

Step 4 - ramp up power and temp and observe the pressure and the power out

Steps 1, 2 should happen today. Steps 3 and 4 will be several small steps and will take most of tomorrow. On Wednesday we can turn the power off and see how the time constants compare. We may test heat and cool several cycles.

Нmm it appears like your ѕite ate my first commеnt (it was super long) so
I guеss I'lⅼ just sum it uρ what I submitted and say,
I'm thoroughly enjoying your blog. I as well am an aspiring
bloɡ writer but I'm still new to thе whole thing.

D᧐ you have any tips and hints for inexperienced blog writers?
I'd really appreciate it.
