Quote:I don't get the 'unleaded gasoline' description on the Coleman. Is there LEADED gasoline ANYWHERE? Probably not but these things have been around a long time and when they first came out there was, so the name stuck.
It also prevents confusion as Coleman fuel is also known as white gas. This is the preferred fuel as it burns cleaner and hotter but I have burned unleaded in mine and it works fine although more maintenance is required.

So i take you own one of these Exponent Feather's? How are they, does the gas leak at all or is the container tight? How about eficiency? How long does it work on one tank? And finally how much does that lil tank hold? Sorry but i couldn't find much info on the Coleman site... thanks again... oh one other thing, do you know what the diff between these two

I have used a coleman over the stove drip coffee maker, then a french press, now I just take instant coffee with me! Sure, its not as tasty as fresh ground but I just want to keep things easy and simple and a spoon of instant in hot water is about as simple as you can get!

I'll second the use of the Coleman white gas stove & a Melita drip cone into a thermos. I am far too picky about my morning cup - When tent camping I still carried whole beans, ground them using an inverter for power, and the one burner stove to boil the water. Worked great, fast, and simple.

Certainly not as efficient as electric, since not all the chemical energy in the gasoline is converted. And not all the heat produced is going into the coffee. Most of the heat produced is being used to evaporate the moisture produced during combustion, and to warm and move the surrounding air. Not sure why the focus on efficiency, though. Most of us look more at cost and energy density and availability.

Im pretty sure this is my word, a decent cup is crucial, especially since ill be in some areas with fantastic bean

The focus on efficiency is because im going to be living out of a van for over 1.5 years in Central and South America. Propane is NOT readily available and i only have so much battery power so electricity is a minimally available. In other words the goal is to have a vehicle that can dry camp for as long as possible without using the engine so efficiency is very important....

"MRP Coffee.... hmmm sounds convenient, but perhaps not very tasty..."
Nothing to do with MRP rations! Only the TECHNOLOGY came from the military.
These heated coffees for the commercial market started out "Back East" in the US or Europe, I believe, for the yuppy/way busy/Starbuck get-it-in-a hurry group at about $4 each. Now I think they may be available nationwide for way less, $2 each on down perhaps.
Great for day hikes and "reasonably short" RV trips where the idea is to not cook at all, or much at all. (Like us on some short RV jaunts.)

I just run a 120 volt coffee maker off an inverter
Someone said
Quote:Maybe they are 100% efficient when it comes to using power, but as for creating heat to make coffee hot, it would seem there is an efficiency factor.....
The difference is not in making heat, as noted resistance heaters, at least SPACE heaters, are 100% efficient, A coffee maker might b 99.9% but there is some loss in the power cord and plug so it's not quite 100.
The difference is in keeping the coffee hot.. In days of old it was often a stainless steel container... Today it's often something with an R-Factor much greater than ZERO. (Heat transfer resistance factor)
in the case of a 12 volt coffee maker..Due to the fairly stiff current load. Losses in the wires and power cord add up fast.. Thus I suspect my use of the 120 volt device powered by the Prosine 2.0.. Is more efficient Much more.. Due to power cord losses being 10% of what they are in a 12 volt job
Nothin adds excitment like something that is none of your business

Why not hang a Black & Decker auto coffee maker under the counter and fire up the genny when you want coffee. That's my setup and when on hookups you can set it to make coffee at any time in the morning.
