[[Image:biogas diagram.jpg|thumb|center|600px|A cross-section of a fixed-dome digester. For further information on how this works, and for other types of biogas digesters, see the Practical Answer's [http://practicalaction.org/biogas-answers technical briefs on biogas].]]
 
==Costs==
'''Cost of bio-digesters:'''<br>
The flexible balloon installations are relatively cheap (30-100 US$), but are liable to damage. Floating drum and fixed dome digesters are more expensive (700-1200 US$), but are more robust. Floating drum installations are effective, providing gas with a fixed pressure, which is good for domestic use, but can be more expensive and less robust than a fixed dome digester. Fixed dome digesters are more robust as they use no moving parts and can be constructed from local materials.
