    If we were starting from scratch (as with new housing developments and new cities being built in China and India, for instance), what would we do with the ability to have cheap hydrogen production from urine using relatively inexpensive fuel cells?

    We could install the separating toilets mentioned in the link above, collect urine on a community basis and generate electricity from it locally, with little transmission loss. Hydrogen could be stored for backup use when local wind and solar are not available, making these renewables more practical.

    If safe composting toilets are available (and they have been in use in one multistory Canadian university building for years), we can save huge amounts of water now used for flushing.

    Pumping water is very energy intensive because water is heavy, so reducing fresh water use would be an enormous efficiency. IIRC over 30% of California's energy use is pumping water. Fresh water is in short supply anyway, so using much less water is a direct benefit as well.

    The compost would enrich the soil and could be collected by companies or a municipal utility which finishes turning it into topsoil.

    Thinking systemically can take us a long ways.

    How can all human beings have satisfying lives while at the same time nature becomes increasingly vibrant and healthy?
