assistant: knowledge
Me too but we've got some real knowledgable folks on this echo.
"Gas powered" refrigerators used to be real common in rural homes around
here.  They were usually called "Servels" because that was the brand name of
the leading supplier.  I still see them advertised once in a while.
I also have seen natural gas fired commercial air conditioners (for office
buildings, etc.).  I dunno what would stop a person from using something
similar (whether gas heated or solar heated) in a home.
The main drawback I can see is that you wouldn't have any cooling after
sundown.  I don't know about Arizona but here in Oklahoma, it can be
uncomfortably hot for several hours after dark.  Maybe if you used a combined
gas/solar setup??
would
As to how much heat - not a lot really.  The old Servels had a flame about
the size of a pilot light on a gas range.  Self regulating?  I kinda doubt
it.  You'd probably have to build in some sort of control circuitry but, what
the heck, electronics are simple these days.

Write your reply.

assistant: The point of hit and miss engines is not that they disable the spark above
govern speed, though some do. It is that they leave the exhaust valve open -
hence the wheezing noise!  Thius means that they dont need a throttle, which
is for various reasons a waste ofd energy, and the combustion conditions are
always the same. This removes one dimension from the problem of tuning which
makes the engine able to work on a variety of fuels, and get good efficiency
when running light.
The throttled stationary engines became important when used for electricity
generation, where for AC power you dont want bangs every secondor two or
three...!

Too brief by far! What does an LCB *DO* and why should it be necessary?
urely
there is no need to "stabilize" the current delivered by a PV array!!
  This current is sent
That makes sense, and the obvious question that results is- are the
electrolyzers cheaper/ more durable/ more efficient than conventional
batteries? What's the attraction of an electrolyzer?
Importantly, can the electrolyzer support the huge momentary overloads that
batteries can supply? It would be a considerable on- cost, if all the
appliances in the subject house had to be modified for "soft start". Common
household  AC motors have starting currents in the range of 4 to 20 times
ull
load current. Very inconvenient to have the lights go out each time the frig
starts up!
  The hydrogen
I assume this is the usual space satellite type rig- oxygen and hydrogen go
in, DC electricity comes out, and beaut clean drinking water is the waste
product.
I think you have glossed over this a bit, What do you mean by "1 kW power
supplies"?   I had assumed you
meant, DC inverter fed by battery. If you mean DC inverter fed by
electrolyzer, I suspect there is no such beast commercially available. Your
project will get very costly if you elect to use a hefty battery to support
the electrolyzer! And, with the existence of such a battery the merit of
having an electrolyzer at all, fades.
OK I got your meaning wrong. You meant an engine driven generator, these
[here] are petrol or diesel powered. Having a considerable momentum [flywheel
effect] these can thump out a very high momentary overload as can a battery.
This ability, may not be matched by the electrolyzer/ fuel cell rig. Fo
although you may have hours of gas in storage, the ability of the fuel cells
to convert this at overload rates would be a central design limit.

assistant: My mother-in-law has a Servel gas 'fridge that must be 50 years old. Still
works, too.
And, we have 2 buildings at work that are air-conditioned with heat. :-) Both
have big York chillers that make cold water from steam; the cold water goes
to heat exchangers to cool the air in the building. There are sure a lot of
pumps 'n stuff involved.
As far as cooling after dark goes, if you cooled an insulated reservoir of
water and drew on that, you could go all night long. Betcha the initial
investment would be a killer!

that nobody is going to get rich off of it. A free sample from a chemical

Plus, Richard Perez is too busy with his chosen life's work (publishing Home

Just a thought, but if you programmed the tracking motors to stop just ahead

 I've printed this entire msg. out, the reason for deletion.
 I'm sure it will come in handy in Florida, while shopping around.
 True, although it wasn't difficult last year with the cold spell that
 lasted a couple of months (Jan & Feb).
 I went back into one of our Workshop Books (April 1980) and there was a
 system in it, that told us how to make it.
 We haven't completely ruled out the Hot Water on Demand yet.
 The existing system in the Mobil is 20 - 25 gallons with a 40 gallon
 backup Solar System, should give us more than enough water, we think!
 Can't thank you enough for all this help.  Really appreciate it.

assistant: In your humble opinion? :)
That may not always be true. Don't underestimate the bright girls and boys
at the forefront of research.
True. You can't just order such a device at local RE supplier, YET.
Not long ago we didn't have true sine wave inverters. As soon as the tech
problems are solved and someone goes into production with the result, you
can bet there will be a market, particularly among rural RE users.
Though it may happen sooner with methane, or ...
That is up to the user. And try to remember, I said 'excess'.
 Any RE home owner can tell you, electricity is the least efficient way to
heat and/or cook. If you were to use electric heating, range, dryer, water
heater, etc., You would need a god-awful lot of batteries, and a much
larger inverter, or inverters.
I agree. To dump one system w/o a replacement in place would be very
foolish. But I never suggested such a thing, so, no problem.
Propane serves at present, in my area. As you say, it is currently the
cheapest thing available, But in time it will not be so cheap. Indeed, the
time will come when it is not available at all. That is why it is called
'non-renewable'. And who is going to let us know when we're nearly out?
The government, perhaps? I would prefer not to be caught with my
figurative pants down, thank you. Yes, at present I will continue to use
LP, but I refuse to throw a wet blanket on the possibility of a sustaiable
alternative. As soon as the tech is there, affordable and reliable, I am
sure a significant number 'round here will make the switch, myself
included.

assistant: Cathy,
 You have hit the nail on the head. I'd imagine that the demand for a
DC/PV-powered air conditioner is very low, thus causing extremely high prices
if someone was to try to build such units. The first one always costs a
million dollars, but they get a lot cheaper after a few thousand are out the
door. :-)
