This is a good idea. The only appliance I have that is always on is the
fridge/freezer. I suppose getting a smaller more efficient unit would help
quite a bit. The only oven I have is a small toaster oven, which does nicely
for one person on a diet :-)
Most of the clothes I wear are handwashed or I let the dry cleaner do the
shirts and pants. I hate laundry :-)
I'm going to go ahead it give it a shot although not make much of an
investment at this point. I figure a bit more experience will help when I
move out in the country.
Thanks for the suggestions on the fridge, etc. I'm going to go buy a small
unit this week and unplug the large one and see what the electic bill goes
down to. After that I'll see if I can pick up an energy star compliant
motherboard, etc. for my PC as my mac does and see if I can whittle a few
more dollars off of the bill.
Last question...is there any sort of electric heater one can buy that is
a)safe b)more energy efficient than usual? In the summer I turned on the air
conditioner for about an hour or so weekly and am going to have to do
something about heat this winter. I'd like to see what I could do besides
have a fire (I have all wood furniture) to stay warm without using the heater
in the apt. Any suggestions would be appreciated.

Does Clausius ring a bell?
The transformation of heat to work is always dependent on a temperature drop
and the transfer of heat to a lower temperature level.
This is his interpretation of the law of conservation of energy. (First law
of thermodynamics).  Simply stated:  When a quantity of heat energy
disappears, an equivalent quantity of mechanical, electrical, or chemical
energy appears.
We still need to address the high temperatures and high gas velocities, as
well as the small problem of inefficiency at a lower rotational speed.
If I recall correctly, the lower the working pressure, gas velocity, and
shaft speed...the larger the total surface area of the turbine blades
required to maintain efficiency.
In view of this, I don't see where a turbine small enough for an automotive
application could avoid running at high temps and speeds...bringing us back
to the problems of gear reduction, cooling, and lubrication.

Oil analysis is usually done regularly.  The lower speed of a diesel engine,
coupled with regular servicing (oil, filters, etc) and competent operation
can result in some rather amazing service lives.
100k miles in a year isn't unusual for a truck hauling cross-country freight.
 A lot of folks don't seem to realize that a professional driver doesn't
drive in the same manner as Joe Blow going to visit Yellowstone Nat'l park.
A professional driver tends to push the US limit of 10 hrs./day behind the
wheel very hard.

Glad to hear someone is still working on those things. Back about 30 years

wave of the future and all. I'm not sure how long it was on there, but they
never had any problems with it.
That would probably be a better way to go than a turbine. They could figure
the amount of power required for say a 70 mph cruise and size the fuel cell
to that. When parked it could be charging the battery pack which would
suppliment the fuel cell for acceleration and stop and go use.

assistant: Since the first stage of a switching power supply is a simple

level, high frequency "signal" could make it onto the power line
to cause these type of symptoms. If it did, a simple filter system
should be able to rectify the problem.

Write your reply.

assistant: You don't have to have mechanical transmissions and if one engine goes
out, you can run both props from one engine.  Much better control of
power range too...
There is a reaction chamber before the fuel cell - the gasoline is
broken down in several stages into a hydrogen rich gas, the oxygen
comes out somewhere else and they meet in the fuel cell.
Gasoline has such a *huge* watt-per-volume advantage that it makes
sense to use it for an application like this especially for remote
sites or vehicles.

assistant: Craig Healy writes to Alec Cameron:
Yep, standard procedure; many panels come with diodes prefitted, which
they'll suggest you remove if installing them in series, or by replacing with
a single blocking diode, if in parallel.
It's not usually relevant; most 12V panels have an open-circuit voltage
around 18-20V.  I've measured the difference in daylight current with and
without diodes, and it's very slight indeed; anything lost (maybe 2-3W in
heat) should be more than saved by avoiding any reverse flow losses
ernight.
Of course 'proper' regulators will suffer a diode or transistor drop anyway.

Write your reply.

assistant: What kind of fuel did in run on?  The basic fuel for those
is hydrogen I think.  The big news now is that they
are figuring out how to extract hydrogen from gasoline.
I think it would be turned off while parked for a long time.
I would think a computer would shut the fuel cell down after a
certain length of no-load time.  In other words,
when the batteries are fully charged, the thing shuts off.

You can't use "regular" appliances unless you have lots of money to
spend on more PV and batteries. You can use AC appliances, but they
must be super-efficient. Get a catalog from Trace Engineering in
Arlington, WA. They are the foremost manufacturers of inverters (DC
to AC). Cost depends on capacity and power quality. One of their
best machines, the SW4024, gives 4kW of sine wave power, and costs
about $2500.
I doubt it. :(  You're eliminating at least half of your solar
window to start with.  Buy one panel and a battery and some meters
and play with it. You can learn a lot and be more ready to put
together your system for your land. But don't expect to power much.
