Does anyone have any knowledge, opinions or experience with this particular unit and/or the concept behind it in general?
The item is a "TEG Power" 12 volt (15 watts) thermoelectric generator that retails at $289.99. It operates by sitting on top of a woodstove and converts heat into electricity that can charge a 12 volt battery.
The TEG Power company is based in Morgantown, WV, and looks to be a small but ambitious outfit with good ideas. But how practical is their product and how well does it deliver?
For years I've thought that a generator of this type would be the perfect thing for a small off-grid 12 volt PV/battery homepower system like mine. This time of year of short days and lots of clouds and overcast weather in Northern Wisconsin provides very little PV electric power generation and I am forced to run a gasoline-powered generator. But at the same time my woodstove is fired up and hot 24/7. A near continuous 15 watts would help my battery bank alot when my PV array is putting out almost nothing.
Heck, we're even talking about the charging the battery at night!
A Google search doesn't turn much up about this unit or the TEG Power company in general. One party in Alaska had trouble getting the product delivered and after much delay got a refund. That does not sound very encouraging. Nor does there seem to be anything else like this on the market. Gotta wonder there too. Because a 12 volt thermoelectric generator working off a woodstove seems to be an ideal thing for a small off-grid PV system like mine and I can't be the only one also heating with wood.
You people know a lot more tech stuff than I do so any comments or information would be much appreciated. I'm ready to buy one of these units as $289.99 plus shipping is reasonable, but I don't want to be ripped off or vastly disappointed either. Please help.
