I'm not the sharpest tool in the shed but I am a thinker. Since I burn a wood stove 24/7 all winter long anyway. What do you folks that may be a bit more educated than me think of this? I can sure rig it up and fix it. Seems like a good idea to me?

Power a light or two, don't think it would power a TV or computer. Run the fan in a heater, mmm maybe.

I like it, what is the cost?

It MIGHT power a few LED bulbs or it might be enough to make the piezoelectric-electric igniter on a water heater fire off. 25 watts is hardly worth messing with.

Matter of scale.

At the size displayed and BTU's of heat inputted it's a good school science project.

On a larger scale with a much larger heat source it might be viable.

I was thinking more along the line of keeping a bank of deep cycle batterys charged and a power inverter you augt to be able to run lights an TV at night no? I run the tv and lights at hunting cabin with one charged battery.

Ya know, there's a "biomass" electrical generator somewhere in the area around Fort Drum.  Not sure what it burns, whether it's garbage or wood (pretty sure it's the latter) or what the output is (I'll find out today), but I'll find out.  There was an article in USA Today about a year or so ago about biomass electrical power generation being renewable energy, and that the Southeast might be a good place for this kind of energy.

I've read about several types of "biomass" plants - the type that is often referenced for small sale applications is a methane digestor - runs best on ruminant shit.

The plasma gasification plants are pretty neat but need a good source of heat.

Just saw an article on bio-mass plants on the History Channel last Friday. What they do is capture the methane from decaying garbage and use it for fuel for the plant. There's a huge plastic "tarp" as a liner in a pit, the garbage in thrown in and another plastic "tarp" on the top. The methane is scavenged from the top liner and sent to a storage tank for the generator fuel. One could do that in their own back yard with just bio-waste such as grass clippings, etc.

In all honesty, I used to drive by a waste dump near Rosemount, MN. back in 86-90 time frame. They had a stack coming from the ground over the garbage heap, burning off the methane. I used to think to myself, why not capture that methane and use it instead of simply burning it off?? Someone must have a like idea and actually put it to practical use.

There used to be a garbage-burning electrical plant in the Arbor Hill neighborhood of Albany.  Al Sharpton was one of the gang that got it shut down.  Said plant still produces all of the steam that is used in Biggs Lab under the Corning Tower in downtown Albany.

Thor, I've been inside a few of those generator stations.  Small footprint for the generator building.  But, this biomass plant actually does burn wood.

I believe that Denton does that.  I am pretty sure that is how they power their busses.

1.75 to 2.1 amps at 12VDC is better than a lot of solar panels or wind turbines on the commercial market now are capable of.  Done right, that's a right decent trickle charger that doesn't give a shit whether the wind's blowing or the sun is shining.

He might be able to up the output if he just used the radiator unit as a heat exchanger and ran it to a basic steam turbine/generator, but this ain't bad for doing what he can with what he's got (I don't notice an abundance of small steam turbines lying around in scrap piles these days).

BSS, they're actually quite common now. There's one in Elk River & Minneapolis, MN that burns just about everything. However, I don't think they wait for it to generate methane. They do have a fairly small footprint when compared to the coal burning plant in Becker, MN or the Nuke Plant in Monticello, MN.
