[Gasification] "Garringer gasifier"

Dear Bill, Larry Garinger and all

I read over the site and the Garringer gasifier would seem to be a good
deal.  I presume inside it is similar to an Imbert gasifier, and they
typically cost <$1000 (in the 1940s).  I was glad to see that the
incorporated the filter and cooling in the unit.  What doesn't make sense,

The website was a little vague on power level, maybe up to 80 kW? but until
you test it you can't tell how much power can be generated.

I hope this gasifier proves out.  It looks like neat construction and has
all the right words.

It looks as if the gasifier might have a diameter of 14".  If so, our
"Handbook of Downdraft Gasifier Engine Systems" (available at
www.woodgas.com) says it should produce 140 Nm3/h of gas from 67 kg/hr of
wood ~1.2 MBtu/hr input which at 70% efficiency should make 840,000 Btu/hr
of gas energy, 246 kWthermal, at 20% generator efficiency, 49 kWelectric.

So, are you going to buy one Bill?  I'd be tempted if I needed that much,
but living alone I need about kWhr/day.  I could run it for 6 minutes and
store the energy in batteries and I'd be off the grid.  I'm working on a
much smaller gasifier to get off the grid in an hour or so of operation/day.
