My younger sister and her family lived in the NOLA area through
several hurricanes. What they learned is that generators are nice,
but if you need one for longer than a few days, there's one thing to
consider: where will you get the fuel to keep it running? If *I* were
doing this I would look at a natural gas generator, or conversion
kit. Even when electricity goes out for extended periods of time, the
gas is almost always on.

Sales tax is also charged on LP. The Alabama (plus federal) gas tax is $.392,
on $2.37 here now. That's $1.98/gallon, before tax, or $2.13 after sales tax,
or 10% less. Significant?

An engine can only displace a fixed amount of air, the denser the fuel
the higher hp output of any given engine.
Natural gas engines suffer badly from power degradation, LP engines
do too only to a lesser degree.
A gasoline engine run on hydrogen will only produce half the horsepower.
Volumetric efficiency has nothing to do with power from a given
amount of fuel but rather the effectiveness in moving air volume.

I'm paying $2.00 a gallon now, though I will admit to leaching off of an
industrial account, so not exactly retail.

Unless you're certain of having a source of fuel, gasoline should be
your last fuel choice. A 5KW gas generator running at half load needs
about 15 gallons every 24 hours. If you do selective power
generation, you can easilly reduce the generator run time to less than
8 hours a day and even lower with some effort on your part. 30
gallons of gas could last 2 days or 6 days or 10 days - you need to
work out what you absolutely must power (medical equipment,
refrigeration for insulin, etc) and what isn't a necessity. An
alternative for low power devices (CPAP, small fridge, etc) could be
some big deep cycle batteries and an inverter. Charge the batteries
while the generator is running bigger loads; shut off the generator
when the big loads are no longer needed and run the essential items
from the inverter until the batteries reach the half-charge point;
restart the generator and recharge the batteries. (sounds almost lie
a solar setup ;-)
The next fuel choice is diesel, as the fuel keeps for extended periods
if properly sealed, and it's not nearly as dangerous to store as
gasoline. Yes, you will pay more for an 1800 rpm diesel generator
(you really don't want a 3600 rpm diesel) but it will probably last 20
years.
Better than diesel is LP or natural gas. You can store 500 or 1000
gallons of LP for years and it will still be "like new" when you need
to use it. The biggest difference between LP and natural gas is that
you KNOW the LP gas is available but you don't know if the natural gas
supplier is still functional.

No, but a more limited HP engine will burn less BTU's of fuel.
Why not take a chance on learning something.
The following excerpt is from
http://franzh.home.texas.net/lpinfo/index.htm
IC ENGINE EFFICIENCY WITH LPG
Volumetric efficiency determines the maximum power that can be developed
by the four stroke cycle engines due to their distinct induction process.
In another word, volumetric efficiency indicates the ratio of the volume
flowrate of air inducted to the intake system to the rate at which volume
is occupied by the piston. Volumetric efficiency of propane is worse than
gasoline. Theoretical reduction in volumetric efficiency can be
calculated from combustion equation at stoichiometric air-fuel of
mixture. Stoichiometric means the minimum amount of air that supplies
sufficient oxygen for the complete combustion of all the fuel. No free
oxygen would appear in the products of tailpipe emission.
Low density of HD5 propane causes approximately 4 % power loss (which is
the ratio of the volume of fuel to the volume of fuel / air mixture)
compared with only the value of % 1.72 with gasoline powered engine.
Introduction of gaseous fuels in the intake manifold decreases the air
partial pressure notably compared to gasoline. This reduction in power is
inherent the structure of gaseous fuels.
* One way to compensate this loss is to use supercharger or
turbocharger in order to increase air flowrate. Superchargers and
turbochargers provide more power from the engine by compressing the
inducted air higher density than ambient. Volumetric efficiency goes up
with turbochargers and superchargers along with better brake specific
fuel consumption. Turbocharger has a turbine and compressor in a common
shaft. Turbine is driven by the exhaust gas. The using of exhaust gas
provides the recovery of waste energy which leads the increase in the
overall efficiency. An intercooler or aftercooler is applied in order to
provide further increase in the combustion air density. Supercharger is
operated on the same principle with turbocharger. But the driven of
compressor is achieved by engine's crankshaft. Turbo lag which indicates
the delay between boost and throttle response. Because in the event of
sudden increase in power demand, turbine must achieve this. This can be a
problem in spark ignition engines. However this is not noticeable in
large diesel engines. The drawback with supercharger appears in cruise
conditions. Because supercharger can not adjust itself to this condition
due to direct connection to crankshaft as easily as turbocharger can. An
electric clutch that turn the supercharger on and off and a by-pass
application which takes air from the supercharger output and introduce it
in the intake are the current methods for the solution of this.
* Another approach that has been considered is to enrich the oxygen
content of the intake air by using a membrane gas separator or other
means. The oxygen enrichment approach is under research at the present
time and is not available on purchased vehicle.[4]
The second reason which causes power loss is related to the intake
manifold air density. The heat of vaporization of gasoline helps to
decrease the temperature of mixture, producing the dense mixtures.
Although propane and methane have higher heat of vaporization value, they
are already in gaseous state when inducted into the intake manifold and
they do not provide this cooling effect. Development of liquid fuel
injection systems for LPG engines should provide better performance and
efficiency. Besides this liquid fuel injection provides better A/F ratio
control . Back-fire is almost eliminated due to introducing less volume
of explosive gases in the inlet system. Cooling effect of endothermic
expansion of the liquid increase the resistance to pre-ignition and
knock. This leads higher compression ratio which means higher power
output.
Another loss off volumetric efficiency and power is related to
alternative fuel conversion hardware itself. Most engines converted to
burn LPG or CNG suffer an additional 10-20 % power loss due to
obstruction of air flow.[4] This explains the difference between
theoretical power loss and actual power loss.

One reason for the different numbers- Introducing a gaseous fuel to
an engine designed to run on liquid fuel reduces the volumetric
effiecency of the engine and thereby the horsepower and fuel consumption
overall. I suspect the
gas engine and propane engine are identical in displacement.

Here in Al, fuel with no road tax is readily avavable but offroad fuel
is subject to sales tax so the difference in price isn't all that
important.

In the last 4 years I've paid from $2.00 to $3.75, I have my own tank and
can shop around somewhat.

That certainly depends on where you live. In most areas it's 50% higher than
that ($3.00/gal) and some, 100% (e.g. NJ).

That likely includes road taxes. Subtract perhaps $.75 from that. I paid

LP has about 75% of the heat content as gasoline, by volume. If LP is less
than 75% of the cost of gasoline, it's cheaper (your numbers above are off -
you show 90%).

Indeed - real cost depends on what percentage of the time the generator is
running at full load. You won't typically find your generator running at
full load for long periods though. So, we agree that in relative terms,
gasoline is the more expensive, but it's also the more commonly available.
For portable units, you'll pay more for diesel or for LP, so that up front
cost becomes a factor.

For emergency use, get a standard "Contractor's Generator".
10HP, 5 KW, skid mount.
5 gal of gasoline runs 8-10 nhours under full load.
Low cost, noisy, want to run it outside, and change the oil at least

I'll second the Honda. There was a thread on another newsgroup
recently. Someone bought a cheap generator. A small probably
inexpensive part broke on it. He cannot find a replacement part. The
generator is useless. Your chance of finding replacement parts for a
Honda are a lot better than the junk products.
Someone else suggested buying a cheap disposable generator. Fine, but
what if it disposes itself when you need it the most. Not a good idea
for a backup generator. Pay me now or pay me later. Later could hurt
big time.
I built my own generator over twenty five years ago. The engine has a
cast iron block and runs at about 2200 RPM, the generator runs at 1800
RPM. It's made to run for long periods of time and it has. I've run it
for over ten hours a day for weeks on end, just needs gas and oil. I
don't use it much anymore but it's still running, no doubt a 3600 RPM
unit would have died long ago. You can get 1800 RPM generators but the
are a lot pricier than the 3600 RPM versions. The disposable guy
would probably fill his pants if he saw the price of one.
I haven't paid much attention to generators for quite a few years so
I'm not sure about the quality of the power they generate these days.
They used to come in two varieties. A sine wave generator that
produced a clean sine wave that was safe to use on electronics and a
dirty sine wave that could only be used for lights and electric
motors. Mine is the second variety. It can't power electronics. It
will probably fry them.

What you will want to do is a watt-load calculation for all of the
"vital" devices in the house. Freezer(s), refrigerator(s), furnace(or
boiler, or heat pump), one lighting circuit, medical devices, sewage
and/or water pumps, radio (not television), and anything else you need
(one circuit also for phone chargers)
When you get your final wattage, add 10% then you have what you need.
When I was selling generators, people get surprised as to what they
will need. 5KW might seem like a lot, but you might only be able to
run a refrigerator and freezer depending on the age and condition of
them. Switching is a short term solution but after 24 hours, it will
not do any good.
When you get your final wattage, add 10% then you have what you need.
Find a dealer in generators and see what an LP version of what you
need is going to cost you. I say LP as NG might not be operational. LP
is in a tank on your property, so it is readily available. Diesel
would be my second choice. The fuel stores longer than gasoline but is
more expensive than LP to operate and can take longer to get delivered
than LP in certain areas. LP dealers usually have an emergency phone
number and deliver within hours of calling. Also LP tanks are
available at Lowe's, HD, Wally World, or any convenient store. You
would just need to make sure that you have the fittings on hand.
Again, check all of your options.
Now if you only have occasional power outages (less than 3 per year,
each only less than 48 hours), then a decent generator really isn't
worth the investment. Then pick up a small generator. But then they
take the same effort to install (correctly) than a decent 10-12KW
version and would require gasoline. So I would check to see if there
are any gas stations that use a generator themselves or you might be
up the creek. Many gas stations don't use generators unless they are
in a power outage prone area. In this area, I know of only one gas
station that uses a generator.
Finally, check with your code enforcement/ building department. If you
live in or near a larger metropolitan area, some do not allow
portable generators. Some areas require you to have a permit to
operate it. There are some things that they could require you to have
as well.

Buy at least twice what you think you'll need. Do it once, do it right.
Steve
read about heart surgery and how to prepare for it at
http://cabgbypasssurgery.com
If you don't already understand transfer switches and tranfer switching,
take some time and read up on it. You WILL need one for any extended
power outages OR you will be running extension cords all over the place.
Even with extension cords, you will still have issues with devices
that are "hard wired" into your electrical system.

I agree that gasoline should be the last fuel source considered for long
term use, but for a vast majority of folks, the need for a generator is not
that long term. Gasoline works fine for that. I disagree with your
statements about the run time on a gallon of gas - based on my own
experiences with my generator(s). Around here, a long time without power
might be 4 days or so. Quite an unusual event, but one that you could
expect to happen every few years. I consistently get 12 hours of run time
out of my generator on a full tank. Hell - I'm not even sure what the size
of the tank is but it's certainly not more than 5 gal. I backfeed the whole
house with my 5.6Kw and I really wouldn't be able to guess how much of a 24
hour continuous run is at 1/2 load, full load, etc.

Get any brand with the type of voltage outlets and setups you are looking
for that is powered by a genuine Honda engine.
It is the only engine that I feel confident in saying that it will start
immediately after long periods of time without attention.
They will also start after filling up the tank, while it is very hot from a
long, high power run.

When Hurricane Yikes hit Houston, FOUR MILLION people were without power for
over two weeks! That included most every gas stations for 60 miles.
We had a generator and five gallons of gas. BFD!
Now, when a hurricane hits the Gulf, I've got 60 gallons of empty gas cans
that are gonna get filled.

Like I said, he has to check his area.
Consumption is based on the spec's given by the manufacturer. Since
they break it down based on gal/hr, the heat content is moot as it
would be misleading otherwise.
Most states you are not exempt from any gas taxes unless you are a
farm or government. Doesn't matter if it is delivered.
Pricing is based on my area. I called our local LP provider to check
what the price is. It is 1.99/gal here. I used 2.00 just for math
sake.

I would still not hesitate to buy a Honda, but I read a blog somewhere
about tricks to quiet noisy or quiet generators, even further.
This guy welded a short fitting for auto exhaust pipe over the outlet of the
generator's muffler. He used a piece of flex pipe to hook up a muffler
mounted on the side of the generator frame with rubber mounts; just a cheap
car muffler. He said the mechanical noise of the valves and camshaft and
pistons and rods going about their way could be heard more loudly than the
exhaust note.
He then made up a box from the fiberglass board used to make furnace trunk
lines, and arranged it so any noise escaping from the enclosure had to go
around a couple corners to get out. By the time it had bounced off a
couple pieces of fiberglass board, the sound was pretty much absorbed. He
had a good sized box fan mounted to blow cool fresh air across the
generator, so it didn't overheat. He said you could stand right next to it
running at full load and carry on a conversation at normal volume levels.
Pretty neat ideas out there. I guess the key is to get a large enough
generator to run the house air conditioning so the windows can stay shut so
you don't hear all of the neighbor's generators. If a person had a super
quiet setup, perhaps they could convince the neighbors to make a quite box
for their generators. (with a little help, perhaps <g>)

When there is a blanket power outage such as that, the service
stations are SOL as well.
I always keep my vehicles topped up unless I am on a long highway
burn, then I'll let them get down below 1/4. Seldom below 1/2 in the
city.
Google 1998 Quebec ice storm and see the kind of trouble you can get
into up here.
Sample:
http://www.energyquest.ca.gov/story/images/chap07_ice_storm_picture.jpg
Midwinter power outages can make a serious mess of your house if
you're not prepared. One would be a fool not to have back-up propane,
and generator power in these climes. No electricity, no furnace. No
furnace, busted water pipes. (Leaving them running can be a bad idea
when the drains freeze.)

$2 is unusually low. The numbers rarely work out for LP. LP has other
advantages. Natural gas is, of course, the best solution where it's
available.

Wrong. Heat content is *exactly* the point of an internal combustion engine.
The manufacturer's specs are suspect.

Wrong. You can get an exemption if your use is high enough and you can
justify it.

That is *very* unusual. Like I said, most of the East and North it's $3.00 to
$4.00. I didn't see the numbers for the South and West.

But figure on 5 KW. Make sure you get 220 outlets. Not all of them do.
Honda is a good choice, me thinks.

It depends on how often that there is power outages in the OP's area.
If they are long term (more than 48 hours), LP is tops for efficiency
then diesel then gasoline when compared to run-time versus cost of
fuel. Diesel generators are hard to find for residential use. So that
leaves LP, NG, and gasoline.
http://www.generac.com/Brochures/0183180SBY.pdf
If you base on an 8KW model
LP uses 1.68 gal/hr (at full load). Price that I could find is around
$2.00/gal
Gasoline uses 1.50 gal/hr (at 50% load). The current price for gas in
my area is $2.74/gal
I used to have a sheet that showed the cost savings of all fuel types
but I can not locate it right off. But some simple looking found the
above info.
So roughly about $3.74/ an hour versus $4.11 an hour.
And the above is based on spec of the units. Double the $4.11 if you
want full load on the gasoline.
But again he would have to check his area. This is what it would be in
my area.
And if anybody would like to find out for themselves what they might
need for a generator:

When there is a blanket power outage such as that, the service
stations are SOL as well.
I always keep my vehicles topped up unless I am on a long highway
burn, then I'll let them get down below 1/4. Seldom below 1/2 in the
city.
Google 1998 Quebec ice storm and see the kind of trouble you can get
into up here.
Sample:
http://www.energyquest.ca.gov/story/images/chap07_ice_storm_picture.jpg
Midwinter power outages can make a serious mess of your house if
you're not prepared. One would be a fool not to have back-up propane,
and generator power in these climes. No electricity, no furnace. No
furnace, busted water pipes. (Leaving them running can be a bad idea
when the drains freeze.)
Some more info:
http://canadaonline.about.com/cs/weather/p/icestorm.htm
THE most serious weather-related event in Canadian history.
But uh, how many hurricanes do you have up there. ;~) I see the need, for
winter up there, but gasoline in the south has been harder to get during the
70 and 80's gas shortages than in my previous 4 hurricanes... Gas stations
have generators too, they will be down longer waiting for the employees to
find they way back to work than they will be from power outages. These
places generally get preferential service since they are not normallly in a
secluded area. Oddly the middle of my neighborhood was more secluded than
across the street. Neighboras behind us and across the street from us had
electricity after 5 days. We listened to the friken generators for 6 days.

Something with a Honda engine is an excellent choice. Last year
my brother was in the market for a genset and asked the local repair
guys what they'd buy for their own use. Hands down - Honda. They
also said to avoid the Subaru Robin engine - it is a good engine but it's
impossible for them to get any repair parts. Likewise chinese generators.
If you are considering rolling your own take a look what these guys did.

That's not always good advice. A large lightly loaded genset can consume
more fuel per hour than a properly sized one driving the same load.

Bub, I think you and I must have come off the same assembly line; some of our
mental wiring is nearly identical. :-)

For me the only critical hard wired device was the furnace so I

In our case, I could borrow gasoline from my pickup, which had a 36 gallon
tank, as I recall. The pickup's bed had been modified to make it a dump
bed, so when the fuel filler was being modified, I just tossed away the
barrier that prevented siphoning. It was also a very convenient way to
"bring home" mower gas when I needed to refill a tank.

My BIL had four relatives die from CO poisoning from running a generator in
their garage. Their power had been turned off, but they had the money to
pay the bill. They never figured out WTF they were thinking. Either about
not paying the bill or running the generator inside the garage.
So, even regular people make mistakes sometimes, I guess. Too bad this one
was costly.

My younger sister and her family lived in the NOLA area through
several hurricanes. What they learned is that generators are nice,
but if you need one for longer than a few days, there's one thing to
consider: where will you get the fuel to keep it running? If *I* were
doing this I would look at a natural gas generator, or conversion
kit. Even when electricity goes out for extended periods of time, the
gas is almost always on.
Having recently gone through Ike two years ago and being with out
electricity for 11 days, finding gasoline was the least of my worries, it
was every where. NOLA was a fluke and an ill prepared city.

Most generators sound like the hinges on the gates of hell. They are LOUD!
One nice thing about a Honda is that it is considerably less noisy than the
rest. This enables you to more clearly hear all your neighbors' generators.
