This is promising if they can scale it economically for the farmer. Here in Michigan there are some large dairy farms producing electricity from their manure. But the only reason they can do it profitably is because the cost of the installation was subsidized by both the government and the manufacturer. When I was an agronomist I worked with several large dairy's in West Michigan on composting their manure. It eliminated most of the odor and had the additional advantage of greatly reducing the volume so they could use an ordinary fertilizer spreader and transport it to fields that could actually benefit from the nutrients. That was 25 years ago and they're still doing it so I guess they found it beneficial.
