The Uboat concept design by Wyatt Little of Houston, Texas, tackles all the major issues associated with green living on a boat. Electricity for the Uboat is provided courtesy of 3 Schüco 180 Watt, 16 Volt solar panels, mounted to a green roof (which we assume can also grow herbs and veggies for human consumption).

Issue number two–sewage–is handled by a toilet which burns waste (yes) instead of carrying it around until the boat reaches dry land. Heating and cooling is addressed by a water-source geothermal heat pump, which uses the temperature between deep, cold water and warmer surface water to create the desired temperature within the Uboat, while rainwater harvesting produces potable water for those aboard.

The idea here was not actually to help us prepare for a watery, dystopian future, but to combat urban sprawl by allowing Uboat owners to live on the waterways–be it canals, rivers, lakes or oceans–of major cities.
