Words of the Weasel Part 48

"Substance" as in "substance abuse".  Used by snowflakes who shrink from calling them druggies or drunkards.  If you cannot name the problem, you cannot deal with it.  And a good strong dose of social disapproval helps druggies kick their habit. 

What's with all this Russia talk by TV newsies?

First they make a big deal about the Russians hacking the DNC and releasing some embarrassing emails to WikiLeaks.  Then they have a field day over the Mike Flynn affair.  Meet the Press spent a lotta time yakking about Russians this morning.   They were clearly trying to sell the idea that the Russians tipped the election to Trump AND that talking to the Russians before the inauguration is treason. 
   Does anyone in the real world believe either idea?

How long do curly bulbs last, really?

The traditional incandescent bulbs claim a 800-1000 hour life.  That's the best compromise between light per watt hour and bulb life.  They sell long life incandescent bulbs, and they do last longer, but they don't give much light.  A 60 watt conventional bulb throws as much light as a 100 watt long life bulb.  800-1000 hours for say a living room lamp that goes on at sundown and burns til bedtime, is 200-300 days, call it a year. 
  The curly bulbs claim 8000 hour life, ten times the life of an incandescent.  That ought to mean ten years service life. 
   And I suppose some curly bulbs do last that long.  A lot of 'em don't.  I have had at least four, die in place after only a year or two of service.  That's out of a total of 8 curly bulbs in my house.  Half the population of curly bulbs dies young.  Mostly the dead ones come out of the fixture with a burn mark on the base, suggesting that some electronic part inside the solid state ballast has failed, rather than the glowing curly tube.  Let's guess that the marketeers who pushed for the 8000 hour life claim  were thinking that the only part that could fail was the curly tube, analogous to the filament in an incandescent bulb.  Solid state ballast failures were ignored.
   On the other hand, as a homeowner, I don't care why the curly bulb died, I gotta replace it for $5 or live in the dark.  But I do think anyone computing lifetime costs of incandescent vs curly bulbs ought to call the curly bulb life as 4000 hours rather than the 8000 hours marked on the package. 

Clean Energy's Dirty Secret

Cover story of this week's Economist magazine.  Comes with a cute graphic cover.   The secret?  Between heavy subsidies and falling costs, a lot of solar cells and windmills have been installed.  Once installed, this equipment runs whenever the sun is up or the wind is blowing.  So on a sunny breezy day there is plenty of juice, and cheap juice at that,  and the expensive central power plants have to shut down until sundown.  The Economist is halfway wised up, they do understand that we need those central power plants to keep the lights on after sundown.  The problem as they see it is to find away to pay for the necessary central power plants when they only get to run and make money for half a day.  The "alternate energy" is supplying power for the daylight hours. 
   There are a few unmentionables with the Economist.  Not once does the phrase "nuclear power" appear in the multipage article. The Economist is virtuously anti-nuclear.   They do briefly mention batteries, suggesting that eventually they will be able to carry the load after dark.  Not likely, anytime soon.  We have been fiddling around with battery technology for better than 200 years.  Best we have now (Lithium Ion) is only maybe twice as good as Alexander Volta's first copper zinc cell of 200 years ago.  We need an improvement of ten times to get a battery good enough to carry the electric grid thru the night. 
   Another unmentionable was "fracking"  In North America, the frackers are producing so much cheap natural gas that the electric companies have given up on nuclear and coal because natural gas is cheaper and cleaner than coal. But the Economist can't breath a word about that because fracking is a dirty word in Europe.  
    The Economist wants, but doesn't quite say so, is government subsidies for central power plants to keep them on line for backup when the sun is down and the wind stops blowing.
   Simpler and cheaper would be to drop subsidies for "alternate energy" and drop "net-metering" which forces power companies to pay "alternate energy" producers for juice they don't need.   But the greenies would freak.. 
  

Combat Readiness

No military unit is ever 100% combat ready.  Troops will be taking leave, some weapons will be out of commission, there are always some shortages in compliment, authorized slots unfilled, some gear worn or obsolete.  So,  something less than 100% is as good as you can do. 
   Back when I was pounding a flight line in USAF, the standard was 71% of squadron aircraft ready to fly every day.  We had to report our percent in commission every morning at 4 AM.  That gave maintenance most of the night to fix the planes that the pilots had broke flying them the previous day.  We had 20 fighters and to make 71% operationally ready, we had to have 15 aircraft in commission, every single morning.  We usually had one aircraft in periodic inspection which took days to complete.  Or undergoing engine change, which took a day and a half.  So we could only afford to have four aircraft down for maintenance after the witching hour of 4 AM.
  Aviation Week ran an article this week about readiness rates.  Somehow USAF was still making 71%, but just barely.  Army, Marines and Navy were only doing 50%.  Back in my day, a USAF squadron commander who failed to make 71% got relieved of duty.  Dunno how the other services feel about the issue, nowadays. 
   Distorting the numbers is the huge amount of aircraft out for depot level maintenance (DLM we used to call it).  At squadron level we only had to report on squadron aircraft.  If we sent an aircraft off for DLM, it no longer counted as assigned to our squadron.  About once a year we would send a plane off to depot, and it would take depot a matter of months to get it back to us.  So something like 2.5% to 5% of the force was in DLM.  That was then
   Now, the Marines are reporting 171 F/A18 fighters assigned to squadrons and 109 F/A18 fighters in DLM.  That's 38% of the fleet out of commission for DLM.  That's bad. Really bad. 
   Aviation Week (staunch industry supporter that they are) is calling for more funding for aircraft maintenance. 
    I wonder how you rate the combat readiness of infantry or tank units. 

Harbor Freight comes to town

They took up half the space in a small deserted strip mall, giving them a big store, about the size of a Staples.  They remodeled, and opened for business the other day.  I stopped in to browse this morning.  They have a lot of stuff in there, hand tools, power tools, ladders, jackstands, welding rigs, a neat little metal working lathe ($569) just about anything you might want. 
  I hope they prosper.  They have to overcome a terrible reputation for quality, actually lack of quality.  I looked hard at the stuff on display trying to judge the quality.  The stuff looks OK, the socket wrenches are nicely polished and bright chrome.  With sockets the only way to tell quality is put the socket on a two foot breaker bar and give it the old heave ho on a stuck nut.  Low quality sockets will break under this stress test, good ones will survive.  Their prices are right, rock bottom low, and for Harry Homeowner who doesn't use his tools nearly as hard as the professionals do,  Harbor Freight can be a deal. 
  I did like that little metal working lathe for $569.  Didn't buy it though. 

Mosul, Iraq

The TV has been talking up the battle of Mosul.  They claim to have taken the half of the city on the west bank of the Tigris river, and are now talking about taking the half the city on the other bank of the river. 
   The TV does not say if allied/Iraqi forces have surrounded Mosul and cut it off from food and supplies.  Since the TV doesn't talk about it, I guess that the surviving ISIS half of Mosul is still in contact with the rest of the ISIS lands.  Which is not encouraging.
   Thruout all history, the way to conquer a city has been to surround it and starve it out.  It's been true since the Greeks besieged Troy.  The Germans tried to take Stalingrad by frontal assault rather than surrounding it.  Did not work out for them.  Cities are man made defensive works.  Fighting from house to house with grenades and assault rifles is the toughest kind of fighting anywhere.  If you have the combat power to push into a defended city, you have plenty of combat power to surround it and then just wait for the defender to get hungry. 
   So what are we doing in Mosul anyhow?  Do we have any US newsies with our forces at the front?
