Abstract:
1. An agricultural waste digester and biogas generation system comprising: a water vessel containing water, wherein the water vessel is configured to support the weight of the entire digester assembly; a buoyant digester assembly placed within the water of the water vessel and having a cylindrical body, a hollow interior, a center axis, and a plurality of wheel segments within the interior of the digester assembly; a gas conduit extending from the interior of the digester assembly to a power generation device; a digester stabilizer assembly rotatably supporting the cylindrical body within the water vessel such that a horizontal orientation of the cylindrical body and the center axis of the cylindrical body is maintained; wherein the plurality of wheel segments are fixedly attached to the cylindrical body such that the plurality of wheel segments extend radially within the interior of the cylindrical body and have an arcuate, contoured surface area which restrict biogas movement within the digester assembly and trap rising biogas under the segments such that an ascending force of the trapped biogas rotates the cylindrical body about the center axis of the cylindrical body and produces an induced agitation of agricultural waste.
