Below is a living collection of technologies that can be (or are being) implemented at various Occupy camps and other temporary, autonomous camps. This is just a start, please add to it by clicking edit or discuss it at Talk:Occupy Sustainability:
Energy generation
Human power
Using a bike, you can generate around 150W of continuous power. E.g.:
- Rowan's portable pedal power generator Nice portable unit for any bike
- Here are two we built for New York City's Waterpod: WaterPod Tour de Volts and WaterPod Bicycle Energy Generator
- Here are two pedal powered TVs that would work well for laptops and other devices: CCAT pedal powered TV and Samoa Hostel Pain in the Axle
- Here are a whole bunch of pedal powered innovations from CCAT: Category:CCAT pedal powered innovations
- For a different take, this rowing machine blender could be made to generate electricity with a generator: Locally_Delicious_rowing_machine_blender_for_schools (note the detailed instructions at Rowing Machine Blender Instructions
- Here is a mechanical bike blender using a flexishaft: Public Health Bike Blender
Solar and wind
Solar panels can cost less than $3 per peak watt. So a 100W panel can cost less than $300 USD. A 100W panel will produce 100W for a certain number of hours a day depending on the amount of full sun as found at http://www.nrel.gov/gis/solar.html. Solar photovoltaic software lists software that can help with design and Photovoltaics#Sizing_a_PV_System covers some of the basics. Example systems include:
- Photovoltaic vaccine refrigeration at Centro De Salud
- La Yuca small scale renewable energy 10W solar and 10W wind for lighting and urban schoolroom.
- Here are a couple of photovoltaic learning stations, one of which is already being used in an Occupy camp: Engr 305 solar learning station and UTC photovoltaic learning station
- Samoa Hostel Windbelt Very low power from low winds and fairly low tech.
Cooking and dehydrating
- Parabolic solar collectors: Papasan chair cooker, Satellite dish and Blackberry bramble, bike inner-tube and tin can lids
- Rocket stoves: WaterPod Rocket Stove and CCAT rocket stove
- Retained heat cookers: Fireless cookers (to cook, food does not need to have heat energy poured into it, it only needs to be kept at a certain temperature)
- Solar dehydration: Simple solar dehydrator, Chris's ENGR305 Solar Food Dehydrator and AEF food dehydrator
Cooling and refrigeration
Water
Supply
- Rainwater e.g. the design at La Yuca rainwater catchment but smaller with 55 gal drums. You can use the calculator at http://www.pequals.com/rain to figure out how big your system can/should be.
Wastewater treatment
- Greywater treatment, e.g. Samoa Hostel Truth Tank and Occidental greywater
Human waste
Housing
Other structures
- Demo Camp Units -
- Weld wood using waste metal to join wood.
