here is a thread I posted years ago on another forum (a Science one).
I thought I`de share it with you all as it might provide a few good laughs
here it is word for word:
Ok, I think I`ve finaly flipped my lid here, lemme give you a little background.
I needed some Potassium carbonate/Hydroxide. best way to get that for free is wood ash, I had no lumpwood charcoal only the briquettes. ****! I only wanted a small amount, and so I set about conducting ANOTHER experiment (the products of which I could use!).
1) what is the least amount of standard charcoal BBQ Briquettes that will make a self sustaining BBQ?
2) Will it work ok indoors and How?
and so I tried, I got an old takeaway tinfoild tray and popped holes in it (charcoal likes Air), placed that on my Pyro testing mount, then stacked up the charcoal briquettes, I found that 4 briquettes is a perfectly workable (although very small) BBQ :)
take a look:
yeah it`s an English £10 note, but it roughly the same size as USA cash.
Anyway,,,,,,, I was sitting next to it (about 2 foot or 60 cms away) and it was still hot, so,,, waste not want not, lets see if it`ll do some toast:
there`s the bread :)))
here`s the results:
well to cut a long story short, my wife told me "NO MORE" after I`de done 5 rounds of toast (I recon I`de have got a good 20 slices done at least out of it!).
anyway, the point other than just interest is this; What is the Ideal configuration using the minimum amount of briquettes to make a self sustaining and USABLE BBQ?
I figured on 4, 3 to make a triangle and one on top to contain the heat, any better ideas are welcome :)
Bon Appetite :)
