The "high G's" and "supersonic speeds" have NOTHING to do with the high cost
of turbine blades. They get plenty of G loading and supersonic speeds while
the engine is on the ground. The amount of G loading from in flight actions
are nothing compared to the normal road shock the engine would see anyway.
Cast as one piece? On what engine? They have a high enough reject rate now on
single blade casting when x-ray inspected that I would hate to see what the
reject rate would be on a one piece casting.
What kind of waste of power will this cause? I would suspect a fairly large
one.
It is not really that different of an application. About the only differences
are the exhaust has to be managed, the load will be constant, and the intake
air will have to be filtered.
I have no prejuices against turbines. I do have experience with them. I have
NOT just read about them in a book or magazine. They are simple in basic
design BUT they are very exotic in materials.

Thanks to a bunch of losers in Washington, DC our naval fleet is still using
a lot of ships that saw service in Korea.  Some are WWII vets.
Steam propulsion is still efficient in larger vessels.  The technology is
proven and the reliability is quite high.  A (relatively) modern steam
propulsion system isn't even close to what was in use 50 yrs. ago.
Combustion air is forced in under pressure, and the air and fuel flow are
constantly monitored and adjusted by gas analization systems which sample the
stack gasses.  Boiler water level is automatically adjusted, and feed water
quality and chemistry are constantly analized by electronic sensors.
Another advantage of steam is that it can be used for purposes other than
propulsion, such as heating, domestic hot water, galley services, tank
cleaning, etc.
The fuel injection nozzles are force fed fuel, which is heated and
pre-atomized by either steam (normal operation) or compressed air
(light-off).  This design allows the use of fuels ranging in viscosity from
heavy (industrial) heating oil up through JP-5 (Jet A) jet fuel.
You might find it interesting to further study marine propusion systems.  A
good reference book on the subject would be "Steam and Gas Turbines for
Marine Propusion" (U.S. Naval Insitute, 1987.  ISBN 0-87021-690-2)
Interesting reading, but a good portion of it covers stuff that requires a
calculator with more functions than mine....and I detest working formulas on
paper.

It is not a matter of size. It is a matter of design. Whether you are making
50HP or 50,000HP isn't the problem. Turbines run at VERY high rpm. This

requires some type of rpm reducing system to make the turbine output
available for ordinary uses whether that is a generator or the rear axle of a

Actually using steam might be better.

applies to solar generated electricity only ( no windmills

to be paid for monthly at regular residential rates,  any
net generation is accumulated and paid at the end of the
year by the utility at their 'avoided cost of generation'.
There is also a credit taken against NYS income tax for
up to 25% of the capital cost of the solar electric system
to a maximum credit of $15,000.

Write your reply.

assistant: There's another problem with Mike's thinking on this 'new generation of
turbines'; he is touting the concept of running them at much lower
temperatures than usual so as to use less-exotic materials in the blades.
Memories of my college physics courses is a bit dim, but there's something
about the laws of thermodynmamics floating around. Achieving high fuel
efficiency requires high temperatures and high compression ratios. Both
Diesel and gas engines benefit from those parameters, and I strongly suspect
that turbines do too.

assistant: Day,
 Most inexpensive inverters are square wave and cause excessive heating in
transformer-type power supplies. This includes the 'wall wart' type of
outfits. Most computers use switching power supplies, and those are not
bothered by square waves.
There are 2 other kinds of inverters: full sine wave and 'modified sine
wave'. The latter is supposedly OK for most all applications, yet is much
more efficient than the full sine wave units. I don't know about regular
power inverters, but my standby UPSs here are full sine-wave and run about
60% efficiency. That gives up a lot of solar and battery power!

 This is indeed interesting and encouraging. How do they propose to measure
this, with 2 meters with ratchets?
What would prevent someone from installing a smallish solar panel outside,
but generate most of his power with a co-gen system that's hidden? I wonder
what their thinking is in disallowing hydro and windmill power?
Thanks for the info!! Now if we can only get such a law passed in Michigan.

Write your reply.

assistant: The intent, as I understand it, is to use the standard unratcheted house
meter,
allowing it to run forward or backward with the net energy flow.
but
Nothing that I can think of would prevent this idea except that the utility
might
investigate if the net generation for a meter-reading period exceeded the
maximum
capacity of the solar panel,  or if the general energy use patterns of the
residence
seemed unusual.  Its probable that a customer who signed up for the program
might
receive more than the usual scrutiny of his usage or production of power
because the
utility would be interested (not necessarily in a suspicious way) in how the
program
was working.  I can't think how it would benefit someone inclined to attach a
co-gen
system to become partly ligitimate by participating.
I believe the utilities fought this law.  Restricting net-metering to solar
under
10kw was probably a compromise with their concerns.  Even with the tax
incentives and net-metering,  solar generation will probably not attract
anyone
with purely economic motives.  Some ecological/philosophical motive is needed
to make up the economic deficit.  This would insure that the utilities won't
have too much fuss with this stuff.  If hydro, wind, and domestic co-gen were
allowed under a net metering provision there might be more interest than the
utilities would like.  I believe that the Massachusets net-metering law
llows
all of the above forms of generation.  I don't know though, and haven't read
anything, about the results of the Massachusets program.

"Normal" varies between makers, and of course regulators are often drifted
ff
spec. 14.5 is 2.41v/ cell plenty high enough for floating an ignored battery.
For a supervised battery [generating station, phone exchange] the makers used
to prescribe and debate, values in the range 2.25 to 2.35 per cell. One of
he
objections to the higher figure is the rapid fall in voltage when load is
applied. "END CELLS" were used in sensitive applications to allow these to be
inserted/ cut out while on load in order to manage the discharge voltage.
When a battery is a long time on preset float voltage a cell [or cells]
behaves as the runt in the family, and its terminal voltage becomes a little
suppressed. This automatically causes the charger to pump more amps and the
healthy cells in the same battery oblige by raising v a bit, but still
ahead of the runt, and the charger current self limits to a small amps value.
In time a survey of that battery with a voltmeter, may show cell voltages
like:
2.15  2.45  2.45  2.45  2.40  2.60.  Total, 14.50v
The first cell looks very tired [2.15] and the last cell [2.60] looks very
old and may be sulphated and/or low [electrolyte]. Four cells look OK.
After topping up and boost charging at average 2.6 v/ cell, the cell
capacities will have "equalized" and back on float, a more even voltage cell
by cell will be found. The amp hours capacity will have increased. That cell
which was previously floating at 2.60 may need hospital treatment, hence the
use of single cell chargers.
Just before winter, is a good time.  Cheers..........ALEC

assistant: Jim,
This could be good news for everybody, but especially
for people who want to cut their ties to the electric company.
Not everyone can build their house into the side of a hill
to minimize the need for airconditioning.  Normal A/C cooling
requires more power than is practical for most affordable
home power setups.  If this pans out, A/C would no longer
be a reason for not converting to home power :)
Maybe they could have an option of the engine running a
small generator for battery charging.  Actually that
would probably be standard, but maybe you could pay
a bit more for a bigger generator :)
