I don't mean to hijack this thread, but I've just had a major brainstorm in coffee recycling. Please refer to the attached concept diagram.

Simply put, mount a coffee maker to your bike's rack and fill with water and coffee. Brew coffee as usual. Using the optional milk & sugar drip, route the coffee feed straw from the coffee maker to the M&S drip and into your mouth. In 5-10 min., when you make a peepee, the peepee feed line will go through the Uric Acid/Water filter thingie, trapping the uric acid and pee stuff while sending clean, fresh water to the coffee maker to make more coffee.

Since byproducts are produced, it will not make coffee indefinitely unless the optional (not shown) dehumidifier attachment is included or if it's raining.

Please let me know if someone's already invented this system already and I'll withdraw my patent application.
