Re: Catching on (none / 0)

At what point could your community cook on poop? 500 people? 1500?

According to professor Nomad of the Netherlands, never

There, the waste material is brought to normal air pressures and a yeasting reaction starts - producing methane and CO2 which can be used to produce electricity. The first estimates predict that about 10 percent of the houses (so 3 out of a total of 32) can be sufficiently powered this way.

So 50 people can cook out of the poop of 500?

Or are you wondering how large a community has to be before it can build the infrastructure necessary for 10% of its energy to come from poop?

Heh (none / 1)

Yes to your question - What's the minimum limit of people in a community to get a 10% return? If we take the Sneek example, some 32 families (100-120 people?) now forms the lower limit.

But also: Is there a point (scale) that the return gets larger than 10 percent? If we have 500 people, do we get a larger return, say 15%, or will it always be 10%? I've learned in Sweden that a follow-up for some 500 houses in Sneek with the same sewage system is practically go, so we might actually get an answer on that question - in a few years.
