through the roof, further sabatoging an already shakey economy. It
will have NO other effect. No, wait - it will have one other effect -
it will increase Al Gore's income.

Well, it might increase /my/ income, too. :)
FWIW, the customer whose shop is featured at
passed the payback point this spring - and can look forward to *free*
heat and a year-round warm shop for the next 25 or 30 years...
[ Still trying to encourage woodworkers to build their own, but not
seeing many who're willing to help themselves - and I'm having a
difficult time pinning that on Al Gore. ]
Next time I build, I will be contacting you for prices or plans, one or
BTW, in reference to this...
"The construction crew expressed amazement at the temperature and force
of the panel airflow - they were surprised that the air could be moved
so rapidly without blowers."
Does the size and/or shape on the cold air intake vents have anything to
do with this?
Or is it just a case of being big enough?

Morris, I'd take you up on that, but payback here in AZ would be measured
in decades (I buy about $40 worth of kerosene per year to heat my shop).
Get back to me when you get that stirling cycle air conditioner into a
commercially viable format, then we'll have something to talk about. ;-)
If you're going to be dumb, you better be tough
For many years folks from Houston visited New Orleans where we were met with
gracious and exuberant hospitality. I could tell you stories...
So, when Katrina came along, we were more than eager to repay the many
instances of hospitality. We opened the Astrodome and accepted 75,000
evacuees. We tried hard to integrate them into our society.
It didn't work.
I've had more than one Houston Police officer tell me a common refrain is:
"Watch you mean I can't be moseyin' in my 'hood with a malt and a toke?"
Fortunately, the undesirable elements are killing each other off with great
regularity and the remainder experience "Texas Justice."
We don't lack of prison space like California. During the bountiful years we
built prisons as far as the eye could see. Our prison system grows virtually
all its own food - except for a few things like coffee and pepper. The
system has cotton fields, textile mills, and the women's unit takes the
cloth and makes uniforms, bedding, and sundry items.
You might want to browse through the other stuff the Texas Department of
Corrections makes. It's an interesting study.

Anyway, when Hurricane Yikes! came along, and more evacuations from New
Orleans seemed imminent, the Ad Hoc Vigilance Committee for New Orleans
Evacuees was hastily assembled. Members jobs were to stand on the side of
Interstate 10 holding signs that said "This Way to San Antonio."
Lucky you! At one point I needed to heat my shop to get an order out and
burned more than $40 worth of LPG in a single /day/.
I'll invite you to be really specific about what you mean by
"commercially viable format".
The air conditioner is a two-part - or, depending on your definition of
"commercially viable format", three-part problem.
Part one is to produce a Stirling cycle engine suitable for use with
solar heat. We know (sorta) how to build different flavors of Stirling
engines, but there's a lot of R&D needed. IMO, there's a serious lack of
R and even less D - and there are significant political disincentives
for correction of that problem.
My progress has been limited by the fact that I'm only able to spend
about $50/month on the project. I just bought a torch, regulators,
hoses, etc to that I could braze prototypes - and that outlay
represented more than three months of saved-up R&D budget. Oxygen and
acetylene may be do-able next month, we'll see.
My first priority isn't air-conditioning - it's a solar powered pump
suitable for irrigation and village water supplies, and if you have an
interest in how things are going, there's a menu of web pages at
to help keep you up to date. The last link in that menu is to a page
showing progress made by some really brainy young folks who're trying to
help and who don't mind getting their hands dirty to get the job done.
More hands /is/ making lighter work (but their development budgets
aren't any better than mine, and they also have other claims on their
time and energy).
The engines that you see there are the probable forerunners of the
engines that will be the core part of that air-conditioner.
It's looking more and more likely that it won't be me who gets back to
you on the solar Stirling air-conditioning unit, and it may be to your
kids rather than yourself, but it will happen.
