A synchronous generator, it just doesn't use an electromagnet. I believe that this is the same type that's used in windmills, or to generate power from ocean currents/tides.

Does anyone have experience with propane generators? What I'm trying to understand is operational costs compared with gasoline models. The research I've done indicates that they take a performance drop, are affected by low temperature, but no information I've come across outlines fuel consumption and relate this to work undertaken, generator size and cost per hour.

It seems that propane has an advantage over gas, in that the generator will last longer. Another big advantage is that you can conveniently store vast quantities without fear of it going bad (we're all aware of the storage limitations of gasoline).

The conversion to propane is costly, so if I make the decision to switch to propane, it may be best for me to repurchase new equipment and sell my current set-up.. I would however like to gain some real insight from people who have and currently use propane. What are the drawbacks? Thanks for any input you can provide...

Not currently using, but have propane generators (x2), have used them. I started out using one thinking I would use it for battery charging when needed in the winter.I gave up on it in short order. I was using 20, 30 pound tanks and found out I did not seem to get a very good run time out of a tank, then I would be dependant on the local station having someone show up to work qualified to fill tanks.

It boiled down to this, gasoline is everywhere, I can pump it myself, stores for as long as I need it for (Diesel if I need long term),no clumsy, heavy tanks to haul around,no specialised equipment to fill.

Some people love them, though I dont know who because I cant think of anyone I know using one...that might be the telling part.. "using them"

Now if I had one of those big tanks you see in some country yards, where once a year I just make a call and someone comes out to fill it, then maybe I would be happier using it. Each to there own

I was thinking of a 420 pound propane bottle. as far as I can figure out, this is an equivalent of about 120 gallons of gas. as it doesn't go bad, there're no worries. Propane is listed by Ultimate Home Comfort, Halifax as $0.70 liter or $3.11 per gallon. Gas today is $1.21 per liter or $5.38 per gallon. One 420 pound propane battle would save $272.40 ($645.60 - $373.20) or about 40%.

How far it will go is a matter for clarification. One gallon of propane apparently has 73% of the energy of one gallon of gasoline. So if 27% more propane was consumed, it would still save $171.04 or $0.32 a liter. That's quite a bit.

Propane never goes bad, large amounts can be safely stored, convenient refills, saves money, increases equipment life. Moreover when the power's out, it can be pumped without electricity. What's the downside

UPDATE

I now understand that my understanding of the propane/gasoline energy difference is incorrect in the context of a generator. A duel fuel generator produces 73% of the power than what it will produce if it was running on gasoline (although most manufacturers claim only a 8 to 10% reduction in power output). In other words, my 10KW will produce a maximum of 7.3KW and my 4.4 KW will produce up to 3.2 KW saving approximately 40% on fuel. If the output is acceptable, it offers a great saving and a reason to convert or replace.

So how's it working for you?

My problem with propane in Winnipeg is that at -44 degrees it doesn't come out of the bottle. I'm sure I could find a way to warm it up, but hey, make a mistake and you guys will hear the bang.

Propane stops turning into a gas (from liquid) at 44 below.The trick is apparently to have large tanks and short feeder hoses. These can be easily insulated. If you bury the tank in snow or ice, it can fix the problem. In a properly constructed igloo or snow fort, the internal unheated temperature is 0 C. Ice and snow can lower in temperature, but it's an excellent insulator.

This generator is on-sale is at Lowe's for $299! On top of this, if you spend over $250, Lowe's will give you a coupon code for $50 until December 9th. The bottom line is a new Firman P03501 Gas-Powered 4,450 Watt Portable Generator for $249 +tax delivered. It comes complete with a wheel kit included, what a deal!

I'm tempted to buy another despite already having one as a back-up... :-)

I see the Firman 4450W is on sale at Lowe’s again this week for $299.50.

Makes me wonder why they always have them on sale. I have one I bought about a year ago, still sitting in its box as a back up to my back up generator. The price was right I thought.
