Dear Crispin,
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.

regards,
Ron

Dear Friends

 

Now this is an innovation that is worth a quick look – a portable biogas digester!

The link came in a news alert from Energypedia News [email protected]

Jan Söhlemann published a new blog article:

Biogas Backpack

An interesting little thing that i came across a couple of times in the past few weeks.

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.

Although the original article is german, its pretty easy to understand just by looking at the picture:

1m3 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.

The gas is not preassurised. Some weight has to be applied for cooking to press out the gas.

Great idea, wherever small local plants or piping are not applicable!

+++++++++

 

Regards

Crispin
