Fuel consumption:

My guess is 120g over 5 weeks. But this was a special case. Most of the time I was able to purchase milk at the end of the day, so breakfast became granola + milk. Have had more than a few meals with tortillas and peanut butter. I've also encouraged the hospitality industry.

Still, my setup is very efficient. There's the HX pot. There's the transfer valve (no connexion waste). There's the thermometer (the lid stays on, turning off at 80C). There's usage (making tea, warming up ready to eat bolognese, hot water for ramen - I do not cook rice, and certainly not pasta).

So... Making a cup of tea is perhaps 2.5g. same for ramen etc.
