bio log testing

I'm attempting to make some of my own bio-logs and test output.
We've all seen this on YouTube.
And I already know, from other conversations, most think of it as a waste of time..
My curiousity has gotten the best of me (My curiousity is my greatest fault)..

There are many ways of calculating BTU, but still haven't found some good math to work out how much is being produced as "I'm" doing this.

I may be off base on this, but it seems I should be able to use temperature differential, product mass, size of firebox, possibly product wieght, Specic heat(?) and on the list goes.

I'm building a chart and just comparing what burns hotter, longer and recording.

Figure sooner or later I'll stumble upon some good math that would use the info I'm gathering.

I may just have found what I'm looking for.
I'm testing and checking the math to be certain it will do what I hope.
So far so good.

Hello Sprinter!
Happy to see someone curious as I.

Potential I can now gather from breakdown of molecular structure.
Something I have just learned..
Rather interesting in it's self.

Actual output of the stove takes into the aspect of the stove it's self and it's mass.

All I'm looking at is the transference of heat to the air mass within the stove.

Something I believe would/could help us all in considering what a bio-product does for us.

If all I have to look forward to 8600 Btu...
I will make my latest version of the leaf/paper briquette,, getting 6500 Btu from that..
And costs a whole lot less..

I just believe there may be a better way of evaluating..

Then again, I'm just a very curious person.
