Quieten That Generator

See the end of the page should be a video.

Also as gypsysue mentioned the generator and attached piping will get very hot. I measured over 600 degrees near the motor and 250 to 300 degrees 3 feet down the flex tube. Also you will notice in the video (I did as well with my generator) that most of the noise is not exhaust noise but instead engine noise. So the noise blocking qualities of the shed are very important.

Honda...quiet...however, noise is something that works for you as well.

During some generator thefts what some SOB's did was start a lawn mower up and placed it by the generator, then they cut off the generators used at night and stole them.

toss the motor and gear it up to an old chain driven stationary exercise bike.

Any good methods out there?

Here is where we discussed that subject a while ago... http://www.preparedsociety.com/forum/f16/run-your-genny-stealth-827/

Isn't that the opposite of what you want to do? Wouldn't the issue then be overly lowered back pressure?

Carinet: 5. Buy a used marine genset and plumb water and the marine muffler and a water pump into the system. (still have one of these)

I like the idea of a marine system offered by Carinet. Actually saw one for sale and thought it was too much hassle to change it over to conventional radiator and fan set up and exhausrt manifold from heat exchanger. Might just see if its still available.

I can see that water takes the heat out and much the vibration. The heat can easily picked up by reasonably common devices and this would sort that out.

Next problem..... what about the rooms 200 watt light bulb able to be seen in our windows. How can we make it look like a candle?

I am making "blackout curtains" from the reflective space or emergency blankets. In addition to blocking light they will help insulate the windows against summer heat and winter cold. The cheapest ones I have found are at Emergency Essentials $1.25ea for a 84"x52". Their web site is Emergency Essentials - Be Prepared Emergency Preparedness Food Storage.

Another idea is to use the thick plastic sheeting designed to line showers under the tile to create black out curtains. Works like a charm.

I've recently gone away from the idea of getting a generator and here's why:

1. Generators (though the most convenient means of 120AC power) are noisy. Draws attention, makes you a target (or a hospital).
2. Generators run on fuel, which is finite. Sooner or later, the natural gas will stop flowing or the propane or diesel tank(s) will run dry. Then you will be stuck venturing out to look for more fuel. What's the longest period a generator will run before exhausting its fuel? Then you are off to hunt for more.
3. Generators (at least those of significant capacity) are notoriously inefficient. Half of your energy is lost in heat and sound.

I've turned my attention to alternative sustainable power sources. Solar and wind have come along quite a bit over the past few years. That will be my approach if/when I have the option. Hopefully the technology will continue to improve and get cheaper in the future.

But, that being said, if I were pursuing a generator I would buy an enclosed generator (sound enclosure) and do everything I could to bury that generator and it's fuel tank(s) between earthen berms. Get it out of sight and do what you can to deaden line of sight sound transmission. That way you might get to use up the fuel supply before being discovered.

I use the emergency blankets on my windows in the summer to keep the heat down and they are not totally "not see thru" I can see thru them in the summer to the outside and at night you can see light thru them-- so if you depend on them for blacking the light out you will want to back them with something.
I have window quilts that have 4 layers in the winter to block out the cold(and they work well) and they are also not really blocking the total light during the day- but I bet if I got a dark layer for the middle they would block the light completely.
As they are now they do block candle light but not the big electric lights.
But I am really impressed on how much heat they blocked in the summer on the big windows.. I am thinking about putting them on the inside of the quilts to see if they reflect heat back into the room.
