My Little Town 20110331: Etta and Roy Chandler

Those of you that read this irregular series know that I am from Hackett, Arkansas, just a mile of so from the Oklahoma border, and just about 10 miles south of the Arkansas River.  It was a redneck sort of place, and just zoom onto my previous posts to understand a bit about it.

I never write about living people except with their express permission, so this installment is about two long dead denizens of Hackett.

Mr. and Mrs. Chandler were old, even by my grandmum’s standards when I first met them.  They rented that little house that my grandmum owned just to the south of her place.  They moved in around, I guess, 1965 or 1966, give or take a year.  Things were much different then.

Pique the Geek 20110327: How Nuclear Reactors Work. Part the Second

There was a good bit of feedback from last week’s installment, and I want to point out that I am always glad when people point out flaws in my treatment.  I emphasized a particular sort of reactor, and neglected a couple of other ones.  I intend to set this right tonight.

The concern that seems to be in the forefront at present is the radiation leakage from the stricken plants.  As I write this (20110326), it is still not clear whence it comes, but I suspect that fuel rods are compromised and that nuclear fuel rod material is becoming commingled with the water that is supposed to cool the systems.

I say that because it is unlikely that if the spent fuel rod ponds were the source that the high levels of radioactive materials would have found their way into the turbine rooms, where the subcontractors were exposed to extremely high levels of radiation.

The primary thrust of this piece is to go through some of the fission products in the spent (and in use) fuel rods.  This will give us a basic understanding as to why used nuclear fuel is so much more dangerous than new fuel.

My Little Town 20110324: Arthur Holloway

Those of you that read this irregular series know that I am from Hackett, Arkansas, just a mile of so from the Oklahoma border, and just about 10 miles south of the Arkansas River.  It was a redneck sort of place, and just zoom onto my previous posts to understand a bit about it.

I never write about living people except with their express permission, so this installment is about a long dead denizen of Hackett.

Arthur was not a nice man, by any means.  When I was around 10 years old, I would guess that he was around 45, give or take.  I suspect that he looked well over his real age, because he pretty much abused himself.

Working with Your Hands 20110322: Welding

My good friend wanted his trailer to have some metal over the sides of it to use to tie down his riding lawnmowers, his ATV, and his large pull behind mower.  He has several acres to mow, at his farm and here at his house.

Yesterday we went to the hardware store and got supplies, went to his farm to pick up the trailer, and to the welding supply firm to get material.  We welded a little last night, and finished it today.

Welding is almost like art.  One takes a design, and makes it into a fusion of art and utility.  Dad taught me how to weld.

Pique the Geek 20110320: How Nuclear Reactors Work Part the First

With the news about the horrible failure of the nuclear reactors in Japan, it occurred to me that many people do not really understand how nuclear reactors work.  This is the first part of a short series designed to demystify how nuclear reactors work.

All methods for generation of usable amounts of electricity require some sort of energy source.  In photovoltaic units, the electromagnetic energy in solar (or other) photons is the energy source.  In geothermal plants, the interior heat energy from the earth is used, whilst in wind plants the kinetic energy of moving air is used.  Hydroelectric plants use the kinetic energy of moving water.

Fossil fuel fired plants use the potential energy contained in coal, oil, or gas by converting it to heat by combustion.  Finally, nuclear electricity uses the potential energy of a very few heavy elements’ nuclei that is released as heat in the reactor.

Popular Culture (Music AND TeeVee) 20110318: Iconic Themes Part I

I love to be able to fuse two topics into one!  Since almost the beginning of TeeVee, there has been theme music for its programs.  Many of you will remember lots of them, but there were some programs without music, the very first TeeVee image being one of them, although it got a theme later.  Does that pique your interest?

TeeVee became widely available in the late 1940s, in large part because of the revolutionary improvements in electronics because of the necessity of the war effort.  However, there is a backstory to that as well:  after the war was over, there was a flood of components that were military surplus, available for cents on the dollar, to be had by manufacturers.

TeeVee had been invented long before World War II, but the components were rare and expensive.  Because of the glut of surplus components, TeeVee became widely available, but that is more of a Pique the Geek piece.

My Little Town 20110315: Elwood Brockman

Those of you that read this irregular series know that I am from Hackett, Arkansas, just a mile of so from the Oklahoma border, and just about 10 miles south of the Arkansas River.  It was a redneck sort of place, and just zoom onto my previous posts to understand a bit about it.

I never write about living people except with their express permission, so this installment is about a long dead denizen of Hackett.  This time it is about a teacher of mine, Elwood Brockman.

Mr. Brockman taught high school maths, and was also the grade school principal.  Since the entire school system from grades 1 to 12 (no K at the time), double duty was the norm.

Pique the Geek 20110313: Firearms 103. Propellants

For a firearm to operate, there must be an energy source to impart kinetic energy to the projectile being fired.  This is is true in general, but our discussion shall be limited to small arms with only a couple of exceptions.  These materials are called propellants, and the name is quite apt.

The first propellant used was blackpowder, the exact origin of which is lost in antiquity.  For centuries, actually up to very late in the 19th century, blackpowder was the only propellant available.

In the late 1880s what is now called smokeless powder was developed, and has replaced blackpowder in almost all applications except for what I refer to as “boutique” ones.  A substitute for blackpowder, Pyrodex(R) was developed , along with some other substitutes for reasons that will become apparent later.

Popular Culture (Music) 20110311: The Zombies

One might expect that a band that was formed FIFTY YEARS ago this year might have some significant connexions with others, and one would be correct.  That is a long time ago, and The Zombies were early, British, and quite good.  They were not as prolific as many other bands, and almost became victims of their own success in a manner of speaking.

Interestingly, The Zombies were always more popular in the United States than they were in the United Kingdom.  I have no explanation for that other than the hypothesis that when they were getting “hot”, other bands like The Who, The Rolling Stones, and The Beatles were getting even hotter in the UK.

Please come with me to review the career of this very, very underrated British Invasion band.  As a preview to Pique the Geek for Sunday evening at 9:00 PM Eastern, the topic for the evening will be a new installment to my off and on series about firearms, this time about the propellants black powder and the modern smokeless powders, with a nod to Pryodex(r), a more modern substitute for black powder.

My Little Town 20010309: Dee Kirkendall

Those of you that read this irregular series know that I am from Hackett, Arkansas, just a mile of so from the Oklahoma border, and just about 10 miles south of the Arkansas River.  It was a redneck sort of place, and just zoom onto my previous posts to understand a bit about it.

I never write about living people except with their express permission, so this installment is about a long dead denizen of Hackett.  I never learnt what Dee’s real first name was; everyone just called him Dee.

He was a deputy sheriff just about forever.  This was in the mid 1960s to around 1980, give or take.  Here is what I remember about him.

Pique the Geek 20110306: Fricking, Fracking, and Earthquakes

Hydraulic fracturing, also called hydrofracture or just fracking, is a commonly used method to increase the yield of fluid raw materials, usually petroleum or natural gas, from formations that are not “easy” extraction targets.  Easy targets are ones that the fluids dispersed in sands or very porous rock formation.  

Let us dispel a common myth right now:  oil and gas is almost NEVER found as big pools of those materials in large holes in the rock.  Almost without exception, and perhaps quite without exception, these materials are dispersed in some more or less porous rock or sand.    When you see pictures of underground reservoirs of gas or oil, you are really looking at the fluid as it is dispersed in the native matrix.

Sand and very “rotten” sandstone are easy matrices from which to extract the fluids.  Shale and hard sandstone are much more difficult matrices, and hydraulic fracturing is used to increase yields from such formations.

Popular Culture (Music) 20110304. Deep Purple Mark I

There are bands and there are bands.  This band has gone through so many transitions that even I, The Geek, can not keep up with all of them, but I do know that in their original lineup that they were close to, if not actually, great.

Deep Purple were a sort of late on the invasion set band from England, only releasing their first record in 1968.  They did some original material, but their first hit was a cover of Hush, by Joe South, written for Billy Joe Royal, and it was an OK hit.

I only intend to treat the Mark I lineup, because I personally found their material to deteriorate quickly after the band were realigned, although their big hits were later.  Please come with me and explore what was to later become one of the first big hair bands, and one of the loudest in concert.
