I think you misunderstood the article. The bag is only for transport and temporary storage. They take the empty (and some dung) to a biogas producer, get it filled and go home to cook with it. It is supposed to be about a day's cookin' worth.<br/>

Jan Söhlemann published a new blog article:</p>
<p>
<b>Biogas Backpack</b></p>
<p>
An interesting little thing that i came across a couple of times in the past few weeks.</p>
<p>
After a Biogas Plant builder/owner, people in HQ and my boss came up with this independently i think this might be worth a quick Blog, just to let everyone know about this idea.</p>
<p>
Although the <a href="http://blog.zeit.de/gruenegeschaefte/2011/12/05/biogas-per-rucksack-transportieren/">original article</a> is german, its pretty easy to understand just by looking at the picture:</p>
<p>
1m<sup>3</sup> Biogas would about enough for the daily cooking of a family and can be easily transported by one person in a plastic bag with an empty weight of 3kg.</p>
<p>
The gas is not preassurised. Some weight has to be applied for cooking to press out the gas.</p>
<p>
Great idea, wherever small local plants or piping are not applicable!</p>
