Sistema de depuración portable que convierte el agua potable - 1 views

    Ganó el premio del concurso de Bill and Melinda Gates "Reinventar el Baño": "The process of supercritical water oxidation (SCWO) also produces excess heat, despite the presence of water. Energy is only needed to start the system initially, once it reaches a certain temperature the remaining hot water may be supplied to the community directly or used to power an electrical generator."

More hot poop on composting toilets : TreeHugger - 1 views

  •  
    "We can't continue using drinking water to flush away our waste, and we can't afford to keep wasting our waste; at some point soon these are going to be coming into our homes and offices. Don't laugh; already, if you want to build to the Living Building Challenge standard, they are pretty much the only way to go."

Habitat for Humanity construye una comunidad Net-Zero - 2 views

  •  
    Eco Village residents will have community produce gardens and common green spaces and walking trails. There are even plans for a small fleet of communal electric cars. Houses are designed to qualify for LEED-Platinum certification. Houses have their own photovoltaic arrays, between 5 kW and 6 kW in capacity, plus solar thermal systems designed to provide about half of the domestic hot water demand. A separate 75 kW PV installation at one end of the property will provide power for community purposes, such as lighting, and will also produce revenue that can go toward additional construction. The many energy enhancements should save a family between $200 and $300 per month in utility bills when compared to a conventional home of the same size and $100,000 over the course of the 30-year mortgage. Since the project was launched, there has been a 69% increase in the number of volunteer hours donated to the local Habitat chapter, and a 59% jump in the number of volunteers. In all, hundreds of volunteers donated 16,000 hours of time to get the first part of the project complete.
