assistant: Roy,
 Much of the information I got on equalizing batteries came from Home Power
Magazine. The one article even gave the specific rate of overcharge:
C/5 -> C/10 for 5 hours or so. The 'C' is capacity in amp-hours. My
RV/Trolling batteries that I use on my UPSs are 105 Amp-hours, so I charge
them at 5 amps for 5 or 6 hours once per month. Before charging them, I check
the voltage under load with my battery tester, check the fluid, topping off
with distilled water, and recording the battery tester readings.
The UPSs keep those batteries charged at 13.5 volts, but that's insufficient
to equalize the cells.
The equalization requirement is one reason why most home power folks have a
generator set.

assistant: I didn't realize that it was that inefficient!
I saved your entire message -- quite enlightening.
I have ridden a bicycle a lot of miles in my younger days.
It was easy to learn to conserve energy by mostly coasting to
a stop instead of pedalling full speed and suddenly stopping.
Although I am dependent on commercial power, doing some thinking
about what it would take to generate our own power has helped
me be a wiser energy user.

had a 36v motor generator dedicated to excite the fields of the traction
motors when retardation was required. Variable field control of the mg set,
would establish the braking as desired by the driver.
I wasn't thinking of curves, but of the hills and dales due to trackbed

I ride trains a lot here. The banked curve is a failure if the coffee cup is

Surely, no railroad still uses asbestos?! That wood would surely smoulder, if

The Equalizing Charge is sometimes labelled "gassing charge" or "Boost
Charge".
It isn't usually possible with a standard ie "float" charger because these
function at about 2.35v per cell. To boost charge needs about 16- 17 volts
across a 12v battery ie 2.7v per cell. My method is to stop, when all cells
r
gassing vigorously and uniformly. About an hour later, I top up with water
because boosting depletes the electrolyte quantity.
because
:-),
13.8 is a normal charge level, that can be left on a 12v battery
ontinuously,
it is insufficient for equalizing.
I boost charge my auto battery once or twice a year. My wheelchair battery,
about every ten weeks.

assistant: You're correct when comparing turbine to piston engines. We started out
comparing piston engine drivetrains in automobiles to hybrid designs. My
argument still holds: install 2 drivetrains (piston/turbine + electric) and
you've doubled the complexity and increased the expense.
Sure. It looks good on paper, but if you've ever priced a turbine engine
against a piston job, you'll find that your theory doesn't quite hold in the
real world. I'll give you that turbines are more reliable.
You had already revealed that it's a religion with you.
At any rate, Toyota has announced a hybrid-driveline automobile, to go on
sale in December in Japan. It 'may' be introduced into the US. The main
reason for the hybrid is economy and pollution requirments, and this thing
supposedly does very well at both.

But still only a faction of the cost of a new blade. Then wait till a turbine
car owner sees the cost of a hot section tear-down because of hot start. I
would guess they will have to install an interlock to prevent a restart
attempt until after a hot-section inspection in case a hot-start is ever
detected for liability reasons.
Mike is right about the fact they are relacing a lot of recips with turbines
in ag and STOL work, but the cost is over 80K dollars (U.S.) or so. Even if
the price is tripled because it goes into an A/C, a turbine is not cheap and
the Allison 250 is about as simple of a turbine as you can get.

As I remember it started pretty much like I have seen stationary turbines
since start. A pre-lube time until oil pressure reached a minimum, then a
slow wind-up of the turbine with no fuel applied until a min speed was
reached at which time fuel was introduced then ignited, if the turbine caught
all was fine if not it went into a purge cycle then shutdown. Then you
started all over. Total elasped time was around 3 minutes if it started. I
thought the tail pipe was much larger but it has been a long time.

During the first Oil Crisis, new autos in Japan were provided with engine

Pushing the gas pedal later, would automatically restart the engine. This
interesting [but unpopular?!] trick cut pollution and saved gas.
I don't have to tell you of the disadvantages of the scheme!!

I used to have to calculate the ratings for buried power cables, on power
rid
circuits. Depth of burial and soil thermal conductivity, were among the vital
parameters.
Most of the heat escapes upward not outward, and this is easily verified by
site measurements of soil temps. The reason being, that resistance is
proportional to distance and the shortest route is upward to the cool air.
The small amount of heat that flows sideways or down, faces a huge resistive
path hence the soil there gets real hot, and heat is not keen to travel from
one hot body into another hot body!
But! the soil above the source cools rather well being close to a heat sink
[air] and heat runs happily from a hot body into a cool one.
Cheaper yet, just insulate the surface ie the air/ soil interface. Make a
laminate of junk steel sheets, with any sort of waste insulating material
packed between- could be scrap accoustic tiles, expanded polystyrene, egg
cartons, glass bottles....
If the heated mass was [say] 5 x 5 yards then a cover of size 7 x 7 yards
would be effective. But if the heated mass is very deep down [ say, more than
2 yds deep] then more overlap might be justified. More overlap also desirable
if long term heat increase was desired while none was being recovered for
se.
In this case the underside of the laminate would "cook" and a sideways flow
f
energy would seek release beyond the suggested cover. In which case, hot-
oot
it over the dirt and go get more junk steel sheets!   Cheers.......ALEC

When my employer was looking at small gas turbines for electricity

We bought diesel sets instead. Higher first cost, lower maintenance cost,

The bad news, for the turbines we consdiered was the absurd low number of
hours, between the necessary inspections and repairs. The bus operator in San

My first post here, so keep the flame throwers on low for a while :-)
I currently live in an apartment near Dallas and am planning on moving way
out in the boonies sometime next year. I'm planning on building a 'monolithic

as well as try to go underground with it.
I've been reading Home Power magazine for a while and am fascinated by solar
energy, etc. and energy efficiency (got my summer electric bill down to $20
monthly in Texas!), etc.
I am curious about how one would go about powering a house by solar power and
still use regular appliances and not DC like I see in some magazines and
about how much I could expect the conversion equipment to cost. I'd also like
to know if there is any way to solar power a first floor apt with a western
exposure or if it would be worth it at all for the time being.
Thanks!

Write your reply.

assistant: Turbines have their own unique problems also.  A turbine is inefficient at
low speeds, so you have to factor in the added weight of gear reduction
to reuce the uotput to a usable RPM.
Also, the higher speed causes some difficulties with coolant and oil
circulation.  Generally, coolant and oil pumps operate at a relatively low
RPM, requiring yet more complexity to drive them at appropriate speeds.
Higher shaft speed will also result in accelerated bearing wear, unless the
lubricating oil is kept scrupulously clean and continuously fed.
Turbines generally run at a much higher temperature, with accompanying
problems created for the cooling system.  Exhaust temperatures may also be
rather high.
I will admit that my turbine experience has been with steam and gas turbine
marine propulsion, so I may not be aware of methods by which these problems
can be solved in an automotive application.
