Occupy Sustainability

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.
