Should work. There are landfills here in Florida that make enough methane to generate commercial amounts of electricity. Now they're covering those same landfills with PV, for a twofer!

GH,  You might take a look at this URL 
http://www.motherearthnews.com/renewable-energy/waste-to-energy-methane-production-zmaz70mjzkin.aspx?PageId=4#ArticleContent

I found masses of info re composting and 'digesting' for methane by Googling 'Articles about methane gas production for home use.'  There is world-wide interest in composting/digesting both for field and garden fertilizer and methane gas production.  One author states that home methane production units are manufactured and sold in Germany and Switzerland and are in wide use.  Some farmers produce enough methane from manure, night soil, and compost to provide gas for heating, cooking, lighting, and even fueling internal combustion engines.  Author went on to state that any appliance that runs on propane can be easily converted to run on methane.  

An interesting topic.  Thanks for posting.    GOM

I built a modest compost bin recently about 3' x 6' and 3' tall. I usually just mulch my grass and leaves with my mower but this time I collected the mulch in the tractor bags and dumped them in the bin.   Will be using it for our plants.

Just finished the leaves a few days ago before our first snow. Almost got the bin filled to the top.

It's about 25F right now. I just went out and checked it with my temperature gun. The top and sides varies from 25 to 32F.  I dug down about 10" and it was over 100F.  Wow. That was fast.   Steam too.

I wished that I had a long compost thermometer to check down to the middle.

Wanted to run pex tubing inside and to our basement but just can't afford it. Dog gone it.  Would need a bigger pile of compost probably though to get enough heat.

Very cool though. Well hot.

Bert,  Really appreciate the info and hope you'll provide follow ups as time goes by.  I have a compost barrel in my yard which I've nearly filled with kitchen waste, pulled up weeds, some dirt, etc., all mixed up.  I notice it smells bad for just a few days and then nature works its magic and the smell turns earthy   and not bad at all.  I stir the barrel every week or two and also wet the contents down with a hose.  It really cooks!    

My deceased wife and I (mostly her) raised, bred, and showed Great Pryenees dogs for years.  I still have some of the pens constructed of 5 foot high 'sheep' fencing right outside the house in the rear.  Your entry re compost has me wondering if I couldn't do the same thing but on a larger scale and run something like 8 inch diameter pvc or even aluminum drain pipe through an approximaely 20 by 20 foot now unused dog kennel and bring the pipes into the house with an in line fan m0unted to one of them to suck cool air off the floor, circulate it through the compost, and then back inside to the 'fanned' side of the pipe?  

I already use a large drain pipe solar panel big time.  They're great but they don't work at night or on cloudy winter days.  A compost heater, however, would be a 24 hour a day heat provider.  I guess one could even preheat water for a hot water heater using compost.  Why not?  Would appreciate your thoughts.

Thanks a lot,  GOM

I think it's another good idea to provide heat but it would have to be on a big scale to provide a useful amount.
I started too late in the season and didn't have enough grass to go with all the leaves. The pile shrank to a fraction of the original as it decomposed.

Mine is really too small but it will still be useful for compost. If I was back in the country again I would definitely make a huge compost pile with airflow piping and plex piping for heat.

In the Spring I will have more grass than leaves so I may add some shredded branches to help balance it.

I think that running water or some liquid through the pile may be better than air into the house but I really don't know.  

Let me know how it goes if you follow up on your ideas.
