Looks like I need a power cord and a current bush to plug into.
When we had our snowmobiles we had a oven that wood strap on to the exhaust. recipe 40 mph for 1/2 hour will cook a hot pocket. worked great.
I use a Bialetti Venus 6 (expresso) cup stovetop moka pot.
I don't know anything about expresso. I use it to make 1 mug of FAH* coffee in 3 minutes on propane fire. Simple to clean and set up cup 2. Wants a fine grind but not fussy. Brews pretty much any grind you use. How a moka pot works
If I have company my go to is French press, coarse grind 4 minutes brew time. More involved and needs more water to clean up for next round than the moka pot. Makes a little more fancy brew. I read a coffee snob blog where you get a better brew stirring with chopsticks cause they aren't stainless steel like the spoon I use.
Neither needs electricity.
