This is admirable, but doing the math I don't think it's worth the energy.
$6 is what they get for 25 liters of pee. $6 buys you 120 calories at 5 cents per calorie (1). It takes 24 calories to lift one kg one meter (2) 25 liters of pee is 25 kg, so it takes 600 calories to lift 25kg of pee 1 meter. So in order to earn enough money to cover the needed food intake to move the pee you could only lift each batch of pee 0.2 meters.
Put another way, if one moves each batch of pee more than 0.2 vertical meters total during the transport process (or equivalent energy consumption) then there is a net loss, they would have eaten more food energy than is saved.
This is assuming that the $6 you get for a batch of pee is within an order if magnitude or so from its true value. I.e a batch of pee is worth to the world between 6 and 60 dollars given the market price they're paying.
Source says lifting 100 kg 1 meter is 240 calories, so 1 kg would be 240/100 = 2.4 calories (lowercase), or 0.0024 kilocalories or Calories (uppercase). Dietary intake is always in kilocalories.
> To pasteurize the pee, it stays in the jug for at least two months before the farmer applies it
A 2 month "buffer" needs to hold a lot of pee.
This processing time can be reduced to 10 hours by adding watermelon seeds[0], which contain the enzyme urease.
If only the Romans had known this! They stored
large amounts of urine (converting to ammonia) for washing clothes. For this reason, Roman laundries were legally forbidden from being located within city limits.
