![]() Dear gunner, From an email today.... Some time ago you mentioned some disaster preparedness tips on the metalworking news group and I just wanted to write and say thanks. Thanks. When hurricane Isabel came through Charlottesville Virginia we had quite a time but thanks in part to some of your posts my family and I were somewhat ready. I had taken your suggestion and stocked up on a number of items you listed that Sam’s club had and we lived on them for a bit. Though we live in a small city, we didn’t have power for about five days: enough time for refrigeration to become a distant memory. My wife laughed when I bought all the canned stuff but it’s nearly all gone now. Stocking up on water also proved to be a good thing. I had some additional thoughts that you might find interesting: The idea of a small steam plant/ generator has a whole lot more appeal now for a reason I did not expect. Steam power is quiet whereas portable gas generators make a whole lot of noise. Also, in a real disaster, the supplies of gas are going to last about five minutes. Here in Charlottesville, we never ran out of gas, but there wasn’t a whole lot of power to pump it either. Most of the city didn’t have power for about 48 hours. In a larger disaster, I would find loud gas generators something of an advertisement that you might not want to make. A small steam plant would quietly let you continue without irking neighbors. That might sound minor, but believe me, it’s not. In our typical housing development, those who ran gas generators got shunned. Something I used a whole lot: an inverter for the car that let us have two 500 watt ac outlets for the computer and the gas fired water heater. We have one of those new on-demand gas hot water heaters. It needs a small amount of juice to both think and kick off the gas burner. The inverter cost about 30 bucks at Sams. Best 30 bucks I ever spent. Idling the car every once and a while was fine. Thankfully we always had a phone line, so we kept internet service, and with that up to date outside news. Our local news station and the local paper was often not so good, probably because the people writing and publishing it were having to deal with their own problems. Anyway, thanks again. You can post this on the RCM if you like. I’ve not got a news server connection at the moment. Charles Morrill --- "You cannot invade the mainland United States.

Why is it that the home generators are so loud? Is it that the
backpressure of a real muffler is too great? I've heard of people who put better mufflers and even tubing to route the exhaust out of the garage or where ever and they said they were happy. |

Now, THAT is a real post! Thank you!
I've been trying to get an inverter setup to run my furnace, for much the same reason as this fellow mentions. In my housing project, I can hear a generator a couple houses away. No one said anything to me about it when I ran a genny during the ice storm, but I sure would have prefered an inverter and a battery I could charge with jumper cables. What items did you suggest at Sam's? -- Christopher A. Young Learn more about Jesus www.lds.org www.mormons.org .. .. "Gunner" wrote in message ... Dear gunner, From an email today....

That might sound minor, but believe me, it’s not. In our typical housing development, those who ran gas generators got shunned. Hmm. Brings up a good point. Truism: quiet generators are more expensive. But the noisy ones give you more watts/dollar. I would like to be able to run the oil-fired boiler in my house during a winter-time power outage (which runs off a 15 amp ckt, not counting the surge loads), and possibly a refrigerator during a summertime outage. I had helped a friend resurrect an old Onan generator, opposed twin that needed an unstuck valve, and also needed to be re-wired a bit and have the field windings flashed to get it to start. That generator runs at 1800 rpm and is amazingly quite for 3 kw. Does *anyone* still make 1800 rpm generators? Next idea, buy a less expensive, noisy generator and not worry about the noise because a) even though it will be large enough to run the heating system in the house, this will be done during the winter when the garage is packed in snow. Maybe some foam insulation as a sound barrier around the unit to help. Even then it will only be run periodically to keep the house from freezing. It's a detached garage btw, so I could banish the unit away from the house. During the summer such a generator would be well oversize for running a light or two and the refrigerator, again every few hours. I suspect that the noiser generators are not too bad if just idling. Something I used a whole lot: an inverter for the car that let us have two 500 watt ac outlets for the computer and the gas fired water heater. Hmm. An inverter large enough to run the refrigerator. Intersting idea. Must look into that, thanks. The 'internet as news' concept makes perfect sense as well.

SNIP You might want to look at the Honda "EU" series. They have a built-in inverter, which allows the engine to run at different speeds, depending on the load. They also have wiring kits available that allow you to connect 2 units in parallel. I bought an EU2000 last year and like it very much. Very, very quiet and small enough to toss in the truck (one-handed, even) if I need to use power tools away from the house. They are pricey. Also note that the model number indicates surge power rating, not continuous (the EU2000 is rated at 1600W, continuous) Some more info: http://www.mayberrys.com/honda/gener...tgenerator.htm R, Tom Q. |

The 'internet as news' concept makes perfect sense as well. Jim It won't take you long to figure out how bad that idea is. What's the wattage of a refrigerator, even a small one? Do the math and discover how much amperage you'd have to pull from your battery to run the refrigerator. Battery life would be very short. Years ago I built a 12V generator for our boat, which had two small electric refrigerators aboard. I added two batteries to the boat and had to run the generator several hours each day to keep the batteries up. The refrigerators pulled only 5½ amps each, but in the hot environment of Lake Powell, they ran continually. Harold |

Do the math and discover how much amperage you'd have to pull from your battery to run the refrigerator. Battery life would be very short. The idea would be to a) run the truck at some speed above idle, to b) supply 12 volts to a large inverter, so that c) the refrigerator could run for a half hour, every few hours or so. Kind of a stop-gap measure, I know. The downside on this is, in the event of a large scale power failure, it might be better to have the gas in the truck instead of keeping the food cold. The other trouble I see with generator units is, gas powered ones have the fuel go stale. I would be planning on eliminating that problem by using the fresh fuel in 'all those motorcycles' (wife's phrase) in the garage. Keep the generator tank and carb empty until needed, then simply tie into a fuel petcock on one of the bikes. I've heard too many recent stories about generators that don't on account of the carb being gummed up when it's needed. The other possibility is the neighbor who inherited the local radio station backup generator. They had a military surplus willys go-devil motor that was mated to an Onan generator. It's in quite rough shape and would need a motor re-build and a maybe a generator re-wind. Plus I would have to convince him to part with it, somehow. But a nice 3 or 5 kW Honda unit is going for around $2K or so right now. If I invested in the long term strategy I might be able to have something in a shed by the garage that would run the entire neighborhood. But then again, do I really *want* something like that?? :^) Jim ================================================== please reply to: JRR(zero) at yktvmv (dot) vnet (dot) ibm (dot) com ================================================== |

I've heard of people who put better mufflers and even tubing to route the exhaust out of the garage or where ever and they said they were happy. An inadequate muffler is only part of the problem. The engine itself radiates a lot of noise. This is due to design and materials choices made for the cheap air cooled engines. So while adding a good muffler will help, it won't make as much difference as you might desire. This is particularly true for gensets like those sold under the Coleman name, where they cut every corner to get the price down. There are small engines designed with noise control in mind. Onan, Kohler, Honda, Kawasaki, and Yamaha all have engine series designed for low noise. Yamaha in particular has about the quietest "contractor package" available. The difference between it and a Coleman (Briggs powered) is dramatic. If you look at the engines, you'll notice that the low noise ones have added stiffeners cast into the block and head, and the fan shroud is double walled with sound deadening material between the walls. Toro specs a "quiet package" from Briggs for their engines. It has the double wall construction, but doesn't have the head and block stiffening ribs. It is quieter than an ordinary Briggs, but still much noiser than the engines which also have the added stiffening. Gary |

Back in the 1900's they used to jack up on side of the model A and attach a hub the blted to the wooden spokes to run such things as washing machines and buzz saws. Would the be possible to do with todays cars? Some kind of bolt on to the driving wheels that could then be belted to a generator. Ofcourse you wouldn't want to do this to some gas hog. B |

Nah.
You only need a length of black pipe, some other fittings, and maybe even a nice large general purpose off the shelf heavy equipment muffler, and wham! Quiet. You can use a random muffler from a junk yard if you are feeling really cheap... _-_-bear Carl Byrns wrote: On Sat, 11 Oct 2003 12:21:19 GMT, George wrote: Why is it that the home generators are so loud?

Any suggestions on the type of muffler?

The muffler will knock down the exhaust noise, but engine still makes all sorts of mechanical sounds. The cooling fins tend to broadcast those sounds. Been there, done that. -Carl |

On the 40 acres that I share with my brother in a remote spot in
Michigan's U.P., we came up with a simple way to quiet our generator in an otherwise very quiet surrounding - dig a hole in the ground about 4 feet deep & drop the whole thing in the hole. The noise mostly goes straight up & not so loud in a radial pattern. I suppose adding a better muffler would make it better yet... BEAR wrote: Nah.

In article , Strider says...
I wonder if they might have acted differently had they and their families had actually been in fear of their lives. I heard this argument and it does not quite make sense. First off my neighbors would be happy to hear a genset running in my garage, if it were winter and there was an extensive power outage. Because that would mean that after I ran my boiler, we could run a line to each of their houses, and run theirs, each in turn. If you are worried that the sound of the genset means they would be an attraction for looters, most of my neighbors are pretty well armed. I think they would be more worried about their house pipes freezing.

Not if you secured it properly. ![]() I've thought for years that survivalists might be caught between a rock and a hard place if bad times ever do come. People do not always(?) behave rationally. It would't make much sense for them to resent you if you were surviving fairly comfortably and they weren't, even if you had tried to warn them before. Many times, when survivalists try to tell people they should prepare, people treat them like they(the survivalists) are the fools. Of course, they wouldn't want to be reminded later that they ignored what turned out to be good advice. People in that situation aren't usually very receptive to any "I told you so's", especially if they're hungry, cold, worried, etc. It's hard to reason with a hungry man. It is easier to fight for our principles than to live up to them.-Alfred Adler |

This is a metalworking group, one can assume that you'd know to add some appropriate support, as required. Many years ago I did a composite of the hole in ground trick, AND the pipe w/muffler trick to quiet the generators at an underground/impromptu rock concert out in a field. I found a whole lot of 20 ft lengths of pipe under a bungalo, put bales of hay in a 4ft high ring around the generators (sufficiently wide placement - like 6ft plus clearances) - ran the pipe from the exhaust outlet through a hole cleared in the hay bales, then attached the stock mufflers at the end of the 20 ft pipe... quite much quieter, thank you... From what I remember, the concert was fun... and the gens had no problem... :- ) I don't want to admit how many years back that was... geez. _-_-bear |

I was quite proud of how the engine turned out, it and the miniature water cooled muffler and exhaust system, too. I even made a small water pump. If you'd like to receive some photos, please contact me on the side and I'll do my best to copy them from the photo album and send them to you. Harold |
