Well we all hate the sound of Generators humming away when there running , especially when its not yours ......

NOW , i got an idea , that i got from my ski boat ---- When my boat is at Idol In the water -- the exhaust is under the water - so when its running all you hear is a very small rumble bubbles and gurgles -- when my boat is planing ... ITS LOUD .. ( worked V8 350 chev )

Now why cant we extend a pipe from the exhaust that goes into a bucket of water Ie a 20 Litre rubbish bin
i know there will be a little issue with back pressure and perhaps some carbon build up on the plug - but wouldn't this be worth it to quieten these things down to almost no noise? and reduce the embarrassment this creates

has anyone tried something like this ???

Why not just dump the generator into the 20l rubbish bin !!

Just make sure it is full of water first, can't see why anybody needs to take a Generator camping these days, solar is a lot less hassle and cheaper than most quality generators.

Why do you solar boys always turn every thread into a solar vs. generator debate? Your response has got nothing to do with what he was asking

If you don't have anything useful to contribute then why contribute at all

Rossco -- Um i have an 80 watt solar panel that i use to top up batteries for the jayco ( for lighting )

was away for a week some few months back ... and guess what... it was cloudy and overcast EVERY SINGLE DAY

Batteries drained -- wacco ended up getting turned off and all stuff just stuck into the caravan fridge

Its also handy to have a solar Panel if i camp out on Stockton beach in summer time as i have good direct sunlight for 12 hours + a day --- but what about when i am in an area with LOTS of trees
No prob using a Gen here BTW you can camp far away from the next guy that they dont hear it anyway -- and the wind drowns the sound anyway

We also camp a lot in winter time, thus also reducing the hours of usable sunlight in a day

THIS is why i have a Generator , not as my main source but as a back up on those times when there is NO sun available to give adequate charge VIA my solar panel. But thanks for presuming that the sun ALWAYS shines....

Ozboc,

From what you say you seem to be using solar as your primary source to top up 1 battery and use the gennie when solar can't keep up, mate the good thing is at least you're showing some concern in terms of noise when you do use the gennie, good on you.

I don't have an issue if someone wants to use a gennie as their primary source providing they exercise some consideration for others and the problem is there are some who couldn't give a rats!!!

There have been a number of occasions when I have pulled up for an overnight roadside stop been the first to be there heaps of space and someone pulls up right beside me and immediately pulls out a gennie, when if they had of exercised some consideration, they could have parked a long way from where I was. I can put up with the slight sound of a gennie in the distance, 99% are very quiet these days, doesn't worry me.

If I pull up and see someone with a gennie I park well away so it's not going to annoy me it's a shame some people with gennies don't exercise the same consideration.

I don't have a gennie, but I noted what you said about your solar system. I have 2 x 85watt panels and 2 x 100amp/hr AGM batteries and I have lasted a week of cloud running a 110l Waeco which does have an insulator pack. With 2 panels according to the controller the panels were still putting in around 4 amps which was enough to run the Waeco during peak times and sufficient to slow down the discharge process to get me by for the week. I only moved to the 2nd battery on about the fifth day but the first battery still had just under 50% capacity, I just don't like going too far under 50%

Mate I'm not having a go at you just thought I'd let you know and suggest if you get another 80watt panel and a second battery I reckon you'd sustain a week of cloud.

Hey Boc
Not a bad thought but as your chev probably sits in a well insulated sound box most of its noise probably comes through the exhaust BUT most of the gennies have induction noise, running noise and exhaust noise. The bucket of water would only help with exhaust noise.

I made a box for my Honda which works well

greetings John - i actually have one of these generators

direct ebay link

pure sine wave but mine is in blue .....

they have already been soundproofed by the outside casing ( as you suggested)

But your Gen box looks like an excellent idea! 10 points for good work !!

will bookmark your site and when i get time , will make something similar !!!

thanks for the link

Great idea Mottleman I have the same gennie but the noise bothers me so just run during the day to do a recharge. Hope you don't mind me copying your box.

I was out in the sticks a few weeks back, parked by a creek with water, when at about 5:30pm when the birds were nesting a winnebago pulled up alongside. Firstly there was about 300m of parking along the river but he parked about 10m from us and on went his gennie. My wife went and asked him to move somewhere else and he more or less told her to get nicked. Anyway his wife, a much nicer person, said that they would tone it down after they had cooked their dinner which they did. I would of thought that with the rig they had they didn't need a gennie for a one night stopover!!!

Cheers,
Fred

Yes these modern Gennies are very quiet but I wanted to make it quiet enough so I didnt have to worry about using it if/when I wanted to. I didnt want to have to worry about others hating my gennie. The box does this... and it was fun to make with my young fella.

Boc,

The only way to keep a generator quite is not to start them.

The only problem with running the exhaust into water is that it would be so tempting for someone to pour the water down the exhaust to really quieten the generator.

As you may guess I am not a fan of generators. If they are used for a few hours in the middle of the day and placed a long way from camp they can be tolerated.

Having them run of a night, and I don't care how quite they are, sound will travel. I have heard music turned up loud just to drown out the sound of the generator. The generator was running so that they could play music and run lights.
Another pet hate of mine. Music in the bush..

Wayne

Hi Ozboc
Back in the early 70's, we used to extend the Army generator exhausts with a hose running into a bucket of water sunk into the ground a few metres away from the camp.
That way, the bubbling noise was further deadened.
It's well worth a try.
Cheers
I'll get there someday, or die wanting to.

Went camping with friends last week in a NP. Friend has a motorhome - 12v fridge - with 2 x 110ah batteries and two solar panels. I have gas fridge and 1 x 110 battery on the van but carry a Honda 20i. After two cloudy days we were both well down on available power so we fired up the Honda sitting in the back of the Cruiser but leaving the rear doors open. Actually walked around and could not hear the generator outside 30m. and certainly not at the campsite occupied by three other vans some 60 m away. By contrast when threir batteris ran down they just started their vehicles - 2 Nissans and a Toyota and let them idle for an hour or so. We could certainly hear them at a far greater distance.

No problems copying. Like most good ideas, I also adapted someone elses idea a year or so ago.

Length 730mm Width 360mm height 420mm is my box.
Whitworths for the sound insulation
Jaycar for the fans
Bunnings for the powerpoint, catches and handles etc.

Hi Boc
I like a lot of the other respondents hate the things with a passion. Part of being out there involves hearing the sounds of the place as well as the sights. I know Honda owners say that you can hardly hear them but you can and further to that, not everone has Hondas. The noise of radios and music is another issue, don't get me started on that.
We use solar panels to charge our batteries. We stay put at Cape Leveque for a month each year and don't run out of power. With a decent dual battery system and a Engel rather than a Waeco, even cloudy days aren't a problem.
Cheers
Peter

Why anyone uses a generator when camping just amazes me. Thank heaven they're not allowed in caravan parks. I've had to leave a number of free camps and go to Caravan parks for some peace and quiet. I've even seen people running an airconditioner from a generator!!!

I agree entirely.
I have solar, and a genny for emergencies in a sound deadening box. (It virtually never gets used.)
When we go bush we do so for the peace and quiet, which does NOT include listening to someone's bloody genny OR stereo. If someone MUST use a genny- it should be a bloody long way away, and never be run after sunset when we like to have a yarn around the fire or wherever. This is basic manners!

I am a very tolerant person normally, but these things really PI$# me off- for good reason.
I consider my fellow campers in virtually everything I do- so should they!
Hooroo

I think anyone with a semblance of decency agrees with you but there are so many *****s out there who don't give a **** about anyone else. They all seem to think they have the quietest generator of noise on the market. For the record, yes, I have one which I use when necessary and without upsetting others.

The original post though, actually shows that he wanted to minimise his noise when he had to use his gennie.
