Notes from the meating

Reply in thread

I wonder about efficiency. If the meat I get is from 30km away on grassland that couldn't grow crops it's grown on land that is otherwise useless for food. How does using an otherwise useless piece of land factor in? Compared to tomatoes from the other side of the world they came on the most efficient cargo ships

I'll definitely agree with you that animals raised on food humans can eat are terribly inefficient. I also think the meat from those doesn't taste as good as the ones raised on grass

Likewise the river water cows drink is returned in their urine, delivered to the ground not to waterways, reinforced with extra nitrogen which the plants want

I don't believe the efficiency calculations are straight forward except in until most extreme cases

Was that about energy percentage from fat by O2 to CO2, or ketones?

I expect CO2 to show near 80% fat 20% ketones presuming they can differentiate those

Edit to add LLM search result on RQ

Substrate Oxygen Equivalents and Efficiencies

Substrate Oxygen Required to Yield 1 kJ of Energy Energy Produced per Liter of oxygen Respiratory Quotient CO2/VO

a little angina never hurt....

I wonder whether the two words are related, whether English took a Latin word from generic pain and repurposed it for a very specific pain

Anyway it's a commonly known word in English because the common diet causes heart disease so we hear about angina from elderly relatives
