Re: Re: Fuel
Wow, I don't log in a couple days and you guys keep chugging away. Nice looking spreadsheet Glenn! I am surprised people are having trouble with JB Weld in an alcy stove even away from the...

Re: Re: Re: Re: Re: Re: Thermofelt pot lid "hats"
David, That is really interesting. You boiled much faster on the other thread than any of your tests here. I am surprised that changing the lid could have such a profound effect on burn time....

Re: Re: Re: Thermofelt pot lid "hats"
I posted my analysis over that the other thread for those results. Came out to be 48.8% efficient. Fast but inefficient. I am assuming the results in this thread are with an unpolished interio...

Re: Speed AND Efficiency!
Here is my estimate at efficiency of your system: Average time to boil 5:04 St Dev 0.002 Average burn time 5:17 St Dev 0.003 Fuel (g) 14.2 Fuel to boil (g) 13.61 Lower Heating Value ...

Re: Re: Thermofelt pot lid "hats"
I've been thinking about the physics a bit. I am still trying to nail down the burn time results. I think it is clear that the felt must be catching residual combustion heat. Your system 1...

Re: Thermofelt pot lid "hats"
Wow David you are a testing mad man! I took your info (made a few assumptions) and made a stab at estimating the efficiency for each system. 2 and 3 had the highest efficiency. #3 seems to be ...

Re: Is it really an increase in efficeincy?
"Does this really show an increase in efficiency? Increased boil time is often accompanied by a decrease in efficiency. The OP says that 15ml of fuel was used, but it appears that is the amoun...
