| ==Ideas for an off grid + self-sufficient homestead==
| |
| * Home
| |
| ** Structure: [[Earth sheltering and windbreaks|earth shelter]] constructed out of [[Earthbag/Superadobe|earthbags]] using [[passive annual heat storage]] concepts (e.g. insulation watershed umbrella and coupled heat exchange air tube ventilation system) and south-facing greenhouse (as seen in [[earthship]]s) as a direct solar collector.
| |
| ** Heat: [[Rocket stove mass heater]](s) for on demand heat and cooking
| |
| ** Water: [[Rainwater harvesting|Rainwater catchment]] diverted into 3: purified water for drinking / cooking, hot water for washing, and general use cold water for sinks and toilet flush. Hot water partly provided by [[Solar hot water]] system and also a [[thermosyphon]] system coupled with a rocket mass heater. Black water fed into external planter cells with traditional septic tank / leech field as redundancy.
| |
| ** Electricity: combination of [[solar power]], [[wind power]] and small scale [[hydroelectric power]] (e.g. [[water wheel]]) feeds into battery bank. Power usage minimized by careful selection of appliances, lights etc.
| |
| ** Indoor food production via small scale [[aquaponics]] (edible freshwater + coldwater fish in symbiosis with various plants yielding vegetables and fruit) set up in south-facing greenhouse
| |
| * External food production
| |
| ** External [[Passive Solar Greenhouse|passive solar greenhouse]] for larger scale aquaponics system. This structure can include a [[Coop|chicken coop]] for eggs.
| |
| ** External garden for hardy plants such as potatoes, includes black water planter cells and [[Polytunnel]] to boost fertility and lengthen growing season.
| |
| * Income
| |
| ** Passive income
| |
| ** Minimize expenditure
| |
| ** Sell extra food produce
| |
| ** Commercial forestry
| |
| ** Manufacture of goods from freely available raw materials such as wood
| |
| ** Parcelling of land for resale, potentially with planning permission or even finished structures installed to increase land value dramatically
