Neat biogas generator
John Robb seems to be de-emphasizing war and re-focusing on resilience. Here he is on bio-gas generators:
What’s the bottom line?
- This [bio-gas generator] system costs about $750 in materials, plus labor (mostly digging a hole and pouring concrete).
- It generates 20 hours of cooking fuel a day (or 5 hours of electricity generation) per day, plus fertilizer.
- It operates forever.
Sounds like it would pay for itself in less than a year where I live. If it works in the winter! Does anybody know if it will? And what about code enforcement?
And I like this frame:
Don’t Throw Away Wealth
What’s the point of this example?
With some creative thinking, it’s possible to turn waste into wealth at the local level.
You can do this yourself (above ground) or with some neighbors (below ground) or you can contract for it.
If the community has the willpower, a municipal sewage system can use large biogas digesters to generate electricity — likely more than enough to operate a sewage treatment facility and power some community buildings.
Such a lot of interesting work going on these days!
