Hello all,
We are testing a heater unit in a climate room.
The climate room, however, is pretty bare and has minimum wall insulation. Therefore, whenever the heater is off, room temperature drops like a stone, which creates an unreal condition, since ...

"Since we cannot change the climate room structure....
The climate room structure, we need to introduce a thermal mass that will absorb and retain heat when to give the climate room some artifical, but permenant, thermal mass.

What exactly does 'Thermal Mass' mean? When entering information into promash it's asks what the thermal mass is of my mash tun... What is it, and where do I obtain that information?

I don't know much about promash.
Cheers! Thermal mass is quite, and likewise different setups will have different effective thermal masses.
Mass = weight, so I would presume it means the weight of the tun...

I'm planning an outdoor cooker. I saw a couple in Mexico last week that
were interesting, and may have me rethinking this.
I had thought of a large brick one, which would give mass and hence heat
retention. Also higher cost, and more construction.
Then...

If you check out the top quality metal
pits thermal mass....
Is it most important to have mass, thermal
retention, good smoke/heat transference, smoke-tightness the Brinkmann because you
do want some thermal mass.

Why are mechanical and thermal energy different. I know one is a system, and the other one is an object, but need help. Thnks.

The system is called thermodynamic and its energy is thermal energy and thermal energy different....
When work is done averaging techniques can be employed.
Energy and mass are in a sense equivalent.
Be created (from nothing) nor destroyed.

Really play into the potential strengths of solar thermal, which are the low cost and the low mass tank size a bit, reduce the lox tank, and use part of the saved mass on the solar thermal thruster on the solar thermal....

First part of my thread series, enjoy. Oh and if I explained something incorrectly, feel free to correct me.
Heat is the amount of thermal energy getting transfered(didn't expect that, hu? ). "So what is thermal energy, then, smart***?" - you may ask

Power it is Q = m/\T * S with m being the mass....
Watt is the unit to measure power.
Should have typed Mass * speed of light^2 with it's commonly known formula - Einstein's theory of thermal energy being transfered as I said in the post.

What are your thoughts on defeating thermal imaging at night? Would a thermal blanket sown inside a rain poncho work for a short time (before it heats up) or not? I've heard except in cold weather pine trees throw off a thermal signature similar to a ...

My understanding is ....
Don't...etc.
Infrared viewers require an external IR light source.
Infrared ≠ thermal imaging
Thermal imaging "sees" your body heat.
I don't kmow what it is though.
Some SF units use it.
In to make less IR viewable.

Is there a recommend thermal spray process for the repair of scored (to a depth of 0.1mm) machine ways? What would be the recommened powder matierial for ease of applilcation and good scrape-ability?

I doubt you would want to do a thermal spray even it it were it took a day to get it roughed in).

Apple REALLY doesn't know how to apply thermal paste.
Temperature before:
Idle: ~70C
Load: 95C+ (Highest I saw was 97C)
Case Temp: Too hot to handle.
Temperature After:
Idle: ~40C
Load: ~60C
Case Temp: Barely warm.
What did we learn here kids? Apple makes...

It is totally inexcusable....
I mean all the PB's ran fine temperature wise, so that probably them out .
I'm sick of Chinese manufacturing with poor thermal paste implementation.
Damn straight.

So after a small change of plan, I'm having to apply thermal paste to me CPU tomorrow. I've got some Arctic Cooling 5 on the way from Scan, so hopefully I've gone for some of the best stuff.
Any tips on how to apply properly on a Sandy Bridge i3 2100?...
