Mobile, Alabama near the Gulf of Mexico. I will look the
latitude up on a chart.
I like your idea of using discarded hot water heaters. Several
years ago I lived in the interior of Venezuela. We had a cubic
tank on top of the house about 2 m on a side. The sun shining on
that amount of water was sufficient for our needs. A windmill
pumped the water up into the tank.
What do you think of this idea as a comprise:  I have noticed
that we seldom use more than about 10 gallon of hot water at any
one time.  Since I have had little luck in finding a discarded
water heater, I'm thinking of just placing two lengths of 2 1/2" black
plastic pipe on the roof just above the hot water heater. This
would store about 10 gallon and discharge directly into the
existing gas fired hot water heater. Black pipe laying on a
black roof would absorb the heat.  If I placed the pipe in a
box, the box would be about 2 x 21 feet. Area of the pipe
exposed itself is a little less than 9 ft2.  Is this idea
creditable?  I think the pipe would look better that the box?
How much heating capability would I loose by not putting the
pipe in a box?
Appreciate comments.

Hydro is an excellent source though. Wish I had one!  ;-)
You'll need to consider how far the water drops first, to determine

assistant: Mark,
I have been playing with some Hydro across the lake from you in Nothern NY.
Winter operation will be expensive unless there are special circumstances at
your site.  Maybe a windmill is what you need when the water gets hard.
If you describe the site you are thinking about, water volume available and
elevation change, I would take a shot at what kind of hydro system might
be feasable for you.  Also, is grid power available for backup?
Energy Systems and Design makes small systems (about $800) and will sell just
the turbine runner for do-it-yourself ($85). Tel. 506-433-3151.
Harris Hydroelectric (tel 408 425 7652) has similar systems.
Water Power Machinery ( tel 915 697 6955) has a good catalog and design guide
for a few bucks.  They also have a book for about $15 covering design.  They
have
a variety of large and small systems.
Canyon Turbines (206 592 5552) has larger systems ($4,000) and a nice
atalog.
In Vermont, try Vermont Solar Engineering in Burlington (802 863 1202) for
some
advice that would include 'local knowledge' on Vermont specifics.  They sell
some
of the above systems.
Call Home Power Magazine and subscribe on your Visa card.  (tel. 916 475
0830).
They have ads for all the above and descriptions of reader's systems.
Hydro power potential is the multiplicitive product of flow times elevation
change.
Systems are most economical when elevation change is large.  If you have a
fairly flat stream meandering through your acreage, it will cost more than
developing
a mountain brook with a steep drop.
Sometimes do-it-yourself systems can be big money savers.  What are your site
circumstances?

user: You are replying to Robert Sayre about "Power Direction Relay".

Write your reply.

assistant: Robert,
Here is the info on the power direction indicator as I first recieved it.
As shown, some current limiting in the Voltage senseing loop is lacking.
Function is as follows.:
An image of the Voltage transformer neutral is established between the
active diode pair as voltage rises to the diode conduction threshold
in each half wave cycle.  The current transformer current circulates
'hung off' the neutral, developing a voltage, + or - relative to the
voltage transformer center tap, depending on the current direction in
the monitored line. The location of the neutral image swaps places in
the other half cycle.
The output is half wave rectified ac clipped at a 1 diode forward
conduction voltage.
Output voltage can be increased by replacing each diode with multiple
diodes in series, but at the expense of turn-on time each cycle.
I built the circuit (with trippled diodes), but there is not much drive
to the output.  I think the idea will work for control if I put the
output to the gates of a pair of oppositely connected UJT's.
That's to try next.  Thanks for your suggestion earlier.

user: You are replying to All about "OOPS!".

Write your reply.

assistant: Wishing to observe first hand the effect of partially
interconnecting two out-of-phase AC power sources, I determined
to observe the effect via the 'Dark Lamp Method' often used to
determine when the full inter-connection of , say, two
generators, can be properly made.  In this technique, a lightbulb
is placed between the phase conductors to be mated- two
lightbulbs if it's a three phase situation.  The remaining leg is
interconnected (this is often done through transformers to limit
current).  In a single phase situation, the single light bulb
should pulse at the difference frequency (if there is a frequency
difference) or remain steady at some constant level if the
frequency is the same.  If the two sources are in syncronization,
that is, in phase, that steady level is zero, and the bulb will
be 'dark'.
So I hooked my PC-300 $70 inverter neutral to neutral with the
grid house current, and put a 40 watt light bulb between the 'hot
leg' of the inverter and the 'hot leg' from the wall outlet.
I expected to observe a slowly pulsing light bulb and thereby
know how closely the 60hz from each source matched, as well as
confirming my expectations in general.
Instead, the bulb grew quite bright over a period of about 1/2
second, culminating in a blown lightbulb and a $70 smoke signal
from the inverter.
What went wrong?:  I forgot to consider what I should have known!
That when the two sources were 180 degrees out of sync, the
voltage difference would be 240V! ( [+]120V - [-]120V ) -not the
usual 120V that I was erroneously expecting. Dang!
I should have used two bulbs in series.  Hmmmm..., or maybe I
should have just watched a movie or read to the kids.

assistant: Well, 2 lightbulbs would have saved the bulb. I doubt if it would
have saved the inverter, though. :(
 The inverter probably didn't draw enough current to heat the bulbs
enough to make their internal resistance high enough to drop enough
voltage to leave no more than 120 volts for the inverter.
 You might have gotten by with putting the two bulbs in series, and
connecting the inverter across one of the bulbs.

Write your reply.

assistant: Ian,
 You're not "using energy around the clock", just kicking on the
burner/element for a short time every now and again. The actual wastage is
dependant on several factors: how much and how often you use hot water, and
how well-insulated the tank is, along with the length of the pipes between
the heater and the point of use. If your heater is fairly close to the point
of use, and you use water several times during the day, you'll save pretty
much nothing by going to a demand-type unit. OTOH:, if you often go 24 hours
without using any hot water and the tank would be 30+ feet from the point of
use, a demand heater would save "some" money.
When you consider the other costs and increased complexity of the demand
heater, you'll find that it's not the be-all/end-all that many folks think.
