We have a 500 gallon (huge!) propane tank. We are considering running a line that would lead to a small tank, like the one used in gas grills. With that small tank, we can use it for a propran generator for the deep freeze.
At least, I think that is how it works.

We have a regular gas generator that we use when the power goes off during hurricane season. Because of the fumes/smell, we place it outside. It is very loud.

Is the same true for a propane generator? If so, I think the noise would be a magnet when the SHTF for people to know who has power and "stuff".

You would have to place any fuel (propane, gasoline, diesel etc) outside as the exhaust fumes will kill you. A Propane generator will be somewhat quieter than a gasoline generator but will still be noisy. Propane fueled generators are not terribly efficient either, that home depot unit will burn a 20lb tank in 5hrs at full 2000 watt load, 10hrs on 50% load...still not very long on a 20lb tank.

Ususally propane is more effecient , but running a generator to max capacity is not effecient any way .
Think of it this way , driving your car , at idle you use very little , when you excellerate your use is bringing all that iron from 0 to speed takes a significant gulp, now running on the flat it is sipping it along steadally, now you approach a hill ,to maintain speed you must give it more throttle to maintain speed . you hit a head wind you excelerate to keep up the speed.
No load at all, the generator is sipping gas ,every appliance that creates a demand and opens the throttle all the more.
The govener is on a spring and fly weights to maintain speed what ever the load is .
It is designed to run at a spicific speed, to maintain 60 cycles per muinet of electrical current .
That is what your AC electric motors are run on, as well as other cycle sensitive electronics. i.e. refrigerators ,fans, ect .
A lot of people enclose their generators to hide them , but if the cooling air is restricted, it can over heat the unit and age it prematurly.
Personally I am on a battery system, 6 &12 volt . with solar panels . In times past I used my briggs /alternator to charge the battery bank. Most of my lighting is LED floresent and quartz.
This current house I live in is still on the grid , but once I get the gas refrigerator in place , my current electric bill will go from $21. to about nothing .
I have AC generators and welders ,but they are only run for special applications for my tools if necessary . I have added an extra muffler to the diesel gen, but it is still noisey.
But one thing I have in place though If I am running a generator for any reason , it is making a controbution to the battery bank at the same time as well ,even if it is a lite one , making every thing count .
Usually the propane run generators run cleaner,I am told , providing them to run longer in terms of the life span of the unit . If some day you wanted to It could be converted back to gasoline by installing a carburator for liquid gas , it is the only real difference mechanically.

Actually, I believe you are incorrect in your first statement. The efficiency actually increases in a gasoline engine as the % percent load increases. The total volume of fuel increases. So when you are running at low loads, the fuel draw is low, but the efficiency is low.

To fill the 20# bottle from the 500 gal. tank you need a "wet leg" on your large tank. The line running from a large tank usually has a regulator, either a single stage or 2 stage to reduce the pressure. That is a vapor line. To fill the small tank, you need to fill it with liquid.
You could consider a rock crib to quiet the exaust.

I just don't believe any type of generator should be considered in a long-term shtf situation, none of us could store enough gas, diesel or propane to make a difference past a few weeks. Even at 10-15 lbs a day in propane, a 500-1000 gallon tank would soon be exhausted.

I do have (2) gas powered generators and store 80-90 gallons of gas (rotated) I only see those resources for power outages, ice storms etc.

The only reasonable long-term cure would be solar, also with serious consideration on learning how to live without electricty all together.

this right here.

I completely agree about the generators. This is why I only have a small one to run my fridge and freezer during a hurricane. It will be useless to me after I run out of fuel.

during the latest hurricanes there were a lot of problems with people stealing generators. Criminals would start a lawn mower near-by then turn off the generator. The owners would not realize that then generators were gone because the sound was still there.

Wouldn't the owners have noticed their X-box and big screen TV going dark? :confused:

That's what I always thought. If they unplugged mine everything would go off and I would say, hmmm. I even heard my neighbors go quiet one night and ran out to find her son refueling it.
