Poopy power

Whilst our local councils are trying to get 'value' from our waste stream, Treehugger has reported on this research for the National Grid which proposes harnessing sewage, animal and food wastes to produce biogas.

Biogas is nothing new. I've got a book from the 1970's by self sufficiency guru John Seymour where he described a design for a home anaerobic digester to produce your own biogas, and he tells of farmers using such simple designs since the Second World War. As well as producing the gas, the digesters also leave solid and semi-solid materials which can be used as fertiliser.

Much of our natural gas comes from foreign lands so such an initiative would be ideal to reduce our reliance on gas imports; a win in political, sustainability and economic terms.

Given the billions budgeted for ID cards, foreign wars and nuclear weapons, not to mention the welfare payments given to the feckless banking and car industries, £10bn seems like a small price to pay and with a tangible return.
