Foodwaste and Human Waste Power this residence in Spain

Is this how houses will be powered in the future?

A small startup in the sustainable energy space has plans to build a completely self sustaining, off the grid house and accompanying farm in rural Spain. According to FastCoExist journalist Adele Peters. 

The house will essentially function as a giant septic tank, accumulating waste primarily from garbage disposal drains and toilets. Unlike waste in normal septic tanks this waste will be completely recycled and put to use.

Chemical fermentation and bacteria will produce methane gas from the waste at an accelerated rate. The gas provided will be sufficient to power a heating system and electricity.

Additional residue will go toward sustaining a garden and there will likely even be at least a small amount of usable water created as a byproduct of the waste processing system. 

PlantEnergy, the startup working on this project, estimates the house will make construction costs back after as soon as five years. There is possibility the house could eventually not only be self sustaining, but also generating profit by selling energy "back to grid".  

PlanetEnergy founder Meghan Sapp believes this technology will eventually be viable for larger scale buildings. Anaerobic digestion plants and other similar projects generating significant energy from waste are functioning at scale in the U.K. and the British Isles
