minnow or whynot

@ June 15, 2008 1:48 AM in 2008 Denver Westock

outsiders like us need to know how to pronounce the name. the orig french trappers name would rhyme with minnow but now the pronunciation has changed to rhyme with "why not" and why is that?--nbc

wetsock 2009

@ June 14, 2008 7:59 AM in 2008 Denver Westock

to prevent this from happenning again,wetsock 2009 should be held on the 3rd floor of the berry hotel,minot nd.the weather and the neccessity of helping the owner restore the orig one pipe steam system will prevent any hanky-panky from interfering with technical conversations.--nbc

what about putting the batts of insulation on the floor of the 3rd floor?when you have completed the wiring then put them in the attic. your berry hotel looks like an interesting project good luck!! is the propane tank the same age as the building?--nbc

Converting Propane Steam

@ June 13, 2008 8:38 AM in Converting Propane Steam Heat

there is no good reason to junk your steam system,when you can just get it working the absence of a knowlegable steam mechanic you will have to do more of the observation and diagnosis of your steam problems[with a lot of good advice from here].i certainly was able to get our C.1885 7 - unit apt. bldg. up and running better than i ever remember it and i first came to this house 60 years ago when it was coal! i think you can be certain that your system like mine was designed and installed to a very highly competent with the passing of time it just needs help to return it to original operation. get dan's books[if you do not have them already] get a good low pressure [0-48 OZ] gauge from may think you have one pound pressure on your pressuretol but it could be plugged up and allowing more pressure to develop[i keep mine between 2 and 12 oz.]. once you know you are steaming properly you can then pay attention to the waterline the main venting the radiator venting hope this not only helps but even more important maybe you can post some pix of the hotel to lure the wallis up to look at your system!--nbc

wind turbine improvement

@ June 9, 2008 2:08 AM in wind turbine redesign?

when i hear about the huge cranes needed to to erect these monster wind turbines it makes me think that my idea of putting the machinery at the base has even more justification.i am sure that the engineers who have designed these giants have the best of intentions but it looks like a bad design to me.i am sure that there would be no problem in transfering the rotation down to the ground with minimal loss. let us all experiment in our back yards with this and see if it is better up or down!!--nbc

vertical blades

@ June 7, 2008 9:05 PM in wind turbine redesign?

i have also seen vertical blades on some wind turbines-maybe that configuration would lend itself to lower genset placement. when i spoke of a compressor i meant a freon compressor for a heat pump--nbc

aerator suggestion

@ June 5, 2008 10:58 AM in \"i'd like to see them make...\"

judging by the amount of time i spend unplugging or replacing aerators in our old 1886 house no one here will ever suffer from osteoprosis or anaemic iron defficiency,so i would like to see them make one sise fits- all aerators which are reversable so you could blow them out by installing them backwards ,much like paint sprayer nozzles[do oil burner nozzles have this as well?]--nbc

wind turbine redesign?

@ June 5, 2008 10:01 AM in wind turbine redesign?

re dans news letter and the 4 minute video i don't understand why the heavy generator is always placed at the top of the tower.surely some sort of mechanical drive linkage could transfer the rotational power from the blades to the ground where it would then turn the genset [or why not a commpressor as well for a heat pump setup?] valmont ind. west of us here has a self-erecting wind turbine which is a real work of art,but the strength of the tower would not permit the addition of more machinery which could be driven by the wind.--nbc

rotted pipe

@ May 23, 2008 8:36 AM in Replacing Steam Pipe

usually the steam supply pipes are last to rot out [returns are first ]in a steam you need a competent steam man to find out why this pipe failed before simply replacing as it was.[my steam mains are 125 years old!!] i suspect that sch 40 pipe is too light for steam pipes and if the same installer chose the incorrect pipe he probably chose improper fittings as well. when a professional steam fitter takes out his saw to cut apipe he studies the layout with the same care and attention as a diamond cutter so that he can reuse the good threads at the beginning of the bad section. i know that achimedes said: "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world. " but he was never a good steam fitter only good for scortched air in those days!! good luck--nbc


@ May 20, 2008 6:24 PM in photos boiler

make sure you have a 0-16 ounce vaporstat to control the pressure--maybe they are on sale in the summer!! usually there should be more vertical distance from the waterline to the lowest horizontal of the steam main so check those measurements against the installation manual [downloadable from the boiler manufacturers website ]--nbc

@ May 16, 2008 6:54 PM in Peerless or Smith? Any Reviews or Recommendations? or why wouldn't this sort of valve work as a hi-lo-hi vave? i know the boiler manufacturer doesn't offer it but then they really don't know about the importance of LOW pressure steam for heating either.would it be worth a try?--nbc

boiler choice

@ May 16, 2008 5:48 PM in Peerless or Smith? Any Reviews or Recommendations?

no matter which one you choose--make sure the representative for that make is close are unlikely to need any parts--but just in case. also get a vaporstat [0-16 oz.] right off the bat with a low pressure gauge so you can see ounces of sense in just having a standard presuretrol and then throwing it away--better not to have bought it in the first place. there may be an option for a hi-lo-hi burner so give some very serious consideration to that feature which will allow the maintaining of a few ounces of pressure more constantly without the burner on--burner off method. there is more difference between the different boilermen than there is between boiler makes [gross oversimplification ?] good luck--nbc
