Thinner reactor more efficient: more light = less power used to circulate water in a larger volume container.

Best?:

- Two sheets of 5 mil plastic, apply heat to weld together. Weld up the sides. Weld in a zig zag pattern as shown in vid to allow water to fall from chamber to chamber. Thicker plastic easier to weld and stronger, but less light passthrough.
- Need controlled heat source: Weller solder iron? If so, need new (fatter) tip as will be useless for soldering after melting plastic. Heat gun and metal strip clamps for outside?


Hmm:

- recycles bottles, but more energy intensive, no gravity assist.
- easier to make, no plastic sheet welding involved.

Resources:
- Waste water.
- Electric pump (solar + battery source?)
- Vertical support rack (pergola in back yard? sides of house? fence?)


Processing:
- Empty reactor direct to oil press
- barrels for waste water (pump to garden/crops?)
- plastic bottles for oil catch/skim and filter

Would also need to build a biodiesel conversion rig if taking last step, though probably just mix oil in with higher quality purchased fuel to extend it. Means of production for stand alone fuel necessary in SHTF scenario though..

Last week, after MUCH researching and exploring, Jennifer leased herself a new Jeep Liberty CRD:

Despite being a true trail-rated off road vehicle, the CRD Liberty has the second best fuel consumption in its class (22/27)- just after the Escape hybrid, which costs another 5k+ and still is locked into the petro-trap to boot.

Also, it's crazy-fun to drive and just plain looks fantastic (similarities to the Jeep in Silent Hill notwithstanding). =]

CRD means 'common rail diesel', which you can learn more about here:

Yes, that's a Mercedes thing, which they are calling CDI, but they have the same parent company and its the same type of engine so I feel the comparison is pretty relevant.

The current price of PetroDiesel here is 2.90. This will only go up.
The money goes to.. well, the oppressors, frankly; the people that are posting record profits while gas prices soar, the people that tightly control the resource that most of the world is literally fighting over (whether producers or consumers).

The current price of BioDiesel here is 2.90 to co-op members. This will only go down from there due to economy of scale. The membership is $75, but that includes other amenities and helps build the infrastructure to create the benefits of economy of scale, and we have two vehicles on that membership to help amortize that cost/benefit. All fuel and other money goes to the co-op, the farmers, the plant that makes the fuel - all local and small and human and positive. Should we opt to do so, the co-op also does winterized greasecar conversions at a discount to members, as well as pooled grease pickup/process/storage/dispensation.
The URL for the co-op (which has been featured on NPR) is:
