Randomly selected, assorted snacks for your brain:
“We all think of human pee as gross and something that ought to be vigorously “cleaned up” or sanitized. However, human urine is actually sterile (unlike faeces, urine is bacteria-free). This liquid by-product of our daily lives can be a rich food source if it gets into the RIGHT part of the right ecosystem.”
(quoted from submersible design)
Recycling urine as fertilizer is one of the easiest ways to participate responsibly in several major nutrient cycles.

From an energy-returned-on-energy-invested (EROEI) perspective, I’m not so sure about Window Farms (they don’t seem very productive, and they use electric pumps). But even still, I like the idea of sunny windows turned into hydroponic farms, and if you live in Manhattan (like the folks who came up with the idea), that window might be only sole shot at food production. I especially like the recent innovation of upcycling windshield wiper fluid pumps as the recirculating mechanism.
