Using Cow Pats.

[Dennis]

A farmer in Wales ,who is also a world class jeweller, has harnessed the methane from his farm yard using more than a hundred WW2 gasmasks and nearly a mile of tubing to fuel his torch. There’s green!

Well, with a biogas reactor it shouldn't be too difficult to generate enough methane, but at much lower pressures than we'd probably need... I should have a word with the dairy farmer next door to me, shouldn't I?

... or up your intake of beans and brassicas.

My dog is not gonna thank you for this info, but I will, anything to save a penny or two.

I'm off to find the tubing.

Well, it brought out a smile on April 1 and shows there's some life in the old forum yet. Thanks for joining in, Dennis.
