[Gasification] ..OT: Watch your snow load!

Sat Dec 23 06:39:39 CST 2006

Greetings Doug, Arnt, and List members! (Did I say seasons in a previous
post ? If not, Seasons, also.)

As I have just found out, "Doc" from the movie "Back to the future" Does
exist, but in a future time LOL.

Doug, you have earned the status of building "Mr. Fusion" even if it's cold
fusion at that (compared to nuclear). :)

Snow Load, we have some here (about 25cm or so, but this is sub-normal for
us, 1m is common this time of year).

Gasifier FYI,
   I have tried something some what unusual with throat section, instead of
the throat extending down through the lower plate in a gasifier, I moved the
throat completely above that lower plate, and then lowered the entire thing,
(of course needing to add much more charcoal to the gasifier, to compensate
for the extra volume of area around, and below the top of the throat).

Hearth, throats top-lip, and tuyere line are still all in the same relative
relationship to each other, it's just that the lower portion of the throat
is now also insulated, instead of hanging in "free space" in the bottom of
the gasifier...

I have not fired it as yet, it's simply to close to Christmas, and we will
have a house full this year !

BTW Doug, MB Hydro.... I have an engagement with them January 16, in regards
to display of the stationary unit, running the inline 6 engine.

Hi Arnt and Colleagues,

For the moment, we only have sunlight or rain on our roof, so not sure how
to measure that for loading. Although serious for those it affects, we
managed to survive another year of non-gasification. I put it down to the
inner glow of Christmas good cheer, and I have begun serious preparation for
surviving the next few days of over eating and possibly imbibing to excess.
I will probably die of chocolate poisoning.

By a fluke of date line, I live in the future, compared to most of our forum
members, and I'd like to reveal it's a great place and not scary at all. The
power is still on, and I can still drive my car on available gasoline, so
please strive to get to tomorrow, you will survive.

We all need a break, and Christmas is a good time to share some time with
family and  friends, many of mine scattered across the World.

 I wish you all a enjoyable Festive Season, from us down here in New
Zealand.

Doug Williams.
