[Stoves] Biogas backpack

[Max Turunen]

Jean Pain used old tractor inner tube tires for that... much more gas could
probably be contained in higher pressure, and even if heavier, such could
be rolled along... problem: such has much more explosive power and
potential for accidents.... and leaks do occur and can start to burst to
flames :s

But.... inner tires could be used for careful transport to various "depot"
locales in neighbourhoods... route and tire (gas for few days for few
households ?) kept in safe shaded and distant / blocked / fenced range,
away from creatures and kids... far enough... with a hose, from which
portable gas bags could be loaded.... ?

Perhaps usable in some conditions...
