Somewhere on the net there is a bicycle (Stationary exercise) generator, it uses asmall perminant magnet motor for a generator the output is small .
We have mounted a chainsaw bar on an old flywheel style exercycle and it works ok , but you have to bring the wood to it.

Cooler air should make an apsorptive refridgeration unit more efficient but then so should a compressor driven unit. I have not looked into the claims of low temp inefficiencies of compressor refridgerators, but would have to thing it would have to do with frost free systems and the like.
we have  a small compressor fridge that lives in our porch year round , and it seems to be fine, and our large all fridge compressor also is lucky if the air surrounding it is more than 60*F for 6 months of the year, often the temp in our house is 45* first thing in the morning.
I would have to wonder what this innefficiency claim is based on refridgeration is just a heat pump system. Most car /truck A/C cycles to dry the defroster air in winter.
  Prolly didn't answer your questions ,maybe even left more. 

Thanks for the responses , got me thinking more .I read somewhere that temperature differential on the drum of a RMH is a big part of what drives the draft, and thought that jacketing the bottom 1/4 might help this along , still in the thinking stage, I may build a RMH first to learn that system so that I have something to compare to in enlarging the system.
If a conventional ,pre epa wood heater of good design is run hot there is very little ash , it is the slow burn that causes ash in the first place. More head scratching and link reading 

I have been reading/watching  the RMH threads, the biggest advantage that I see is the capture of heat energy and the "clean" exhaust output

I would like to build a "large wood" stove using these principles.
While I see the advantage of the small pieces of wood in a RMH it looks like a lot of work to keep one fed to produce heat on a larger scale.

My thoughts are to build a top wood fed fire box ,well insulated to support hot clean combustion , a secondary chamber like the "barrel" of a RMH and some type of storage mass, then the exhaust . the storage mass might be liquid to provide the function of a outdoor wood boiler without the smoke and incomplete combustion. the stove would be inside of a building to make use of the radiant heat. 

I have been lurking here a long time and this thread finally prompted me to join.
Paul you run an excelent forum congratulations.
I don't think CFL s are all that they are cracked up to be in my experience the failure rate is much higher than advertised, their output is, in light capacity to the human eye, varryed some dimm some very bright. the cycle damage must be more than advertised ,
The EPA is full of a bunch of statistic manipulators.
I think CFL s provide more light for your money but it is mot as nice of light and it takes the CFL s a while to reach full light output. some times they exceed the comparison output .
