Adding Vinegar to the Chicken Water

It’s winter in Wisconsin and the chicken coop isn’t heated. In fact, the chicken coop lacks an electrical connection as well, so except for taking pots of heated water in on the coldest days, trying to heat the coop must come from other sources. The slant of the roof and placement of the window ensure that the coop receives maximum winter heat. The tree that normally shields the coop from the sun during the summer months is bare, letting the sun come through. Even with all these measures, the coop is cold enough to let the chicken’s water freeze.

My goals for various activities on my small farm include doing things in a manner that makes my carbon footprint small and keeps costs low. Consequently, I always look for solutions that don’t involve much in the way of high technology, such as obtaining heated chicken waterers. I did seriously look at a solar powered unit for a while, but decided that the chickens would probably destroy it in short order. The better solution turned out to be adding vinegar to the chicken water.

It turns out that vinegar has both a lower freezing temperature and higher boiling point than water. The freezing temperature of vinegar is 28 degrees, but that level increases when you add more water. I tried various levels of vinegar in the chicken water and found that ½ cup per gallon seems to keep the water from freezing for about an hour longer when the outside temperature is in the 15 to 30 degree range. Above 30 degrees, it kept the water from freezing at all.

Adding vinegar to the water also keeps anything from growing inside the waterer, which means that the water is better for the chickens longer. This feature of adding vinegar is especially important during the summer, when all kinds of green gunk grows inside the waterer and is quite hard to keep out.

If you look on other websites, you find that other people attribute all sorts of other benefits to using vinegar. Other websites warn against using vinegar. I haven’t personally tested any of these claims, so I’m not here to tell you that the chickens derive any benefit whatsoever from the vinegar in the water. However, I did try a simple experiment this past summer and found that given two buckets, precisely the same size, color, and make, one with vinegar and one without, the chickens always drank the vinegar water first. My feeling is that they seem to like it. So even if the chickens don’t gain any solid benefits from the vinegar, you can view it as a treat that helps keep the water from freezing longer and keeps their waterer cleaner.

Considering the Inefficiency of a Global Economy

A lot of people have said a lot about the global economy—how it exists and is pretty much unstoppable. However, a recent article in ComputerWorld, amongst others, have highlighted problems with the global economy. In this case, flooding in Thailand has impacted the availability of hard drivesdriving up the price that everyone pays. If manufacturing were decentralized, flooding in a single country wouldn’t have much of an effect. In short, the emphasis on cost of individual products instead of emphasizing the reliability of multiple sources of hard drives at an increased cost has proven a shortsighted strategy that inevitably hurt the world supply.

Some countries are using the global economy as a source of blackmail. According to the New York Times, China has consolidated its grip on rare earth metals used for everything from compact fluorescent lights to displays used in smartphones. The blackmail started after a disagreement with Japan. As a consequence, the price of any item that requires rare earths has gone up and will continue to increase. It’s another instance where price advantages offered by a global economy have come back to haunt us. In fact, this problem is so significant that the United States government is doing everything it can to create alternative sources, no matter the cost. Unfortunately, it will require nearly 15 years to fully develop those alternatives.

These two stories, and many more, only hint at the potential problems of a global economy. The problems are actually far more severe than you might initially think. When someone ships a hard drive all the way from Thailand to your home, the carbon footprint of that drive is quite large. It takes a lot of gas to move that hard drive. What the global economy does is it trades fossil fuel for price. The cost of the oil, plus the cost of the object (whatever it might be), is less than the cost of producing the object locally. The short term monetary gain takes priority over the cost to the environment and its eventual cleanup. In the long term, that hard drive will cost everyone a great deal more than if it had been purchased locally.

This blog has contained more than a few self-sufficiency posts (60 as of this post). You’ve seen discussions of how to grow your own food and reasonably recycle products instead of dumping them in a landfill. I even told you how to obtain CFLs for free (see CFLs for Free). All of these posts are practicalI’ve worked hard to write posts that demonstrate techniques that improve the condition of your wallet, decrease your health problems, and still help everyone around you by producing a greener environment. Even with these measures, I’m well aware that my carbon footprint is huge because a global economy forces me to buy articles from overseas. These items aren’t available locally and I can’t make them myself.

In the long run, it’s unlikely that we’ll be able to sustain a global economy unless the equation changes dramatically. Fossil fuels aren’t unlimitedwe’ll eventually run out, so from a practical perspective, transportation of items from overseas must change or we won’t be able to transport them. However, long before that happens, the damage to our environment will take a dramatic toll on everyone. The question is why anyone would wait around to see it all happen? Is the world determined to wait until everyone is so sick and so without resources that we have no choice but to toe the line? Does no one think about the effect they’re having until it’s too late?

I ask these questions because the global economy is simply a bad idea. Producing goods locally is far more efficient, even when the initial price for the good is higher. Eating and using what you can produce locally is far better for everyone. You do have a choice. Even with the global economy in full swing, you can buy local goodsin fact, insist on them. Tell local stores that you’re willing to pay more for local goods that are good for the environment. Your money matters. When stores find that they can’t sell those overseas items at any price, they’ll buy locally. “Give the customer what they want” is a cliche, but it’s also a fact. Vote with your cash to bring down a global economy that is ill conceived and killing us all. Let me know your thoughts about the global economy at John@JohnMuellerBooks.com.

 

Windows 7 and the PowerCfg Utility

On page 327 of Administering Windows Server 2008 Server Core, you find the PowerCfg utility and may not even find it all that interesting. Yes, this utility makes it possible to configure the power settings for a system from a remote location. An administrator can use it to ensure that everyone has a power saving setup by adding the command to the user’s login script. However, as utilities go, it isn’t all that interesting. For that reason, the command doesn’t even appear in Windows Command-Line Administration Instant Reference. A number of beta readers said they didn’t even use it.

Microsoft is showing an increasing interest in power management with each version of Windows. In fact, from what I’ve been reading about Windows 8, power management is going to take a relatively large leap forward (read about the changes in, “Building a power-smart general-purpose Windows“). With this in mind, the Windows 7 version of the PowerCfg utility has added four new command line switches:

 

  • /Requests: Enumerates the application and driver power requests. Applications and drivers make power requests to ensure that resources are available when needed. However, sometimes these requests can also become a problem when they’re abused. Power requests can also prevent the computer from automatically turning the display off or going into hibernate mode, which wastes power.
  • /RequestOverride: Forces the system to disregard an application or driver power request. The positive aspect of this command line switch is that you can enforce a power management strategy when you have applications and drivers that abuse power requests. However, by denying applications and drivers access to resources, you could also cause system instability or data loss when the application or driver crashes.
  • /Energy: Performs an energy survey of the system. This is probably the most important addition that Microsoft has made. Using this particular feature, you can detect system elements that are consuming a lot of power and reduce its energy footprint. Generally, you use this feature with just the system running to determine what the system uses. However, you can also use it with single applications open to detect the energy cost of using that application, which I think is actually the more revealing way to use this command line switch. Most people don’t associate an energy cost with using an application. This feature makes the energy cost significantly more apparent. Yes, every application you use has a cost, so keeping needless applications open is costing you money.
  • /WakeTimers: Displays a list of timers that are set to wake the system from sleep or hibernate states. Waking a system too often also costs you money. For example, it costs more to perform individual maintenance tasks at separate times than to perform them during a single time. An organization could use this command line switch to ensure that every system wakes at the same time, performs required maintenance, and then goes back into either the sleep or hibernate states.


As mentioned in the list, I consider the /Energy command line switch the most important PowerCfg addition to date. If you’re interested in self-sufficiency, as I am, then you begin to count even the pennies of energy usage. For example, in my CFLs for Free I discuss how I bought just one CFL and turned it into a complete setup for my entire home. This particular feature has allowed me to perform an energy survey of the applications I use. I found out, for example, that streaming audio using Firefox does indeed cost less than using a separate device for the purpose (such as a radio) and also delivers clearer audio. However, streaming impacts system performance and tacks a network bandwidth penalty onto other applications that rely on Internet connectivity, so there are times where using the separate device is actually better.

Let’s look at the /Energy command line switch in a little more detail. The easiest way to use this command is to open an Administrator command prompt, change directories to a directory you can write in (I’m using C:\Temp), and then type PowerCfg /Energy and press Enter. I purposely ran the command with a number of applications running and some misconfiguration in place to generate some errors, warnings, and informational messages as shown here.

PowerCfg01

The report required a little over a minute to generate. You can see the results in the Energy-Report.HTML file. Here are the results I generated from this run.

PowerCfg02

The PowerCfg utility makes it possible to diagnose energy problems with a system and significantly reduce the cost of running it. The language of the report does require a little interpretation at times, but normally the language is plain enough for an administrator to figure out with little effort. By correcting every error and 12 out of the 13 warnings, I was able to reduce the power requirements of this system by about 15 percent (as measured by a watt meter). So, how does that equate in dollars? You use the equation: Cost = ((Watts / 1000) * Hours Used) * kWh rate, where kWh is the kilowatt hour rate provided by your power company on your electrical bill. This system was averaging a little over 520 watts before tuning it. For the sake of argument, let’s say you’re using it 60 hours per week and the electrical rate is $0.12. The weekly cost of running this system is:

 


((520 / 1000) * 60) * 0.12 or $3.74

After tuning this one system the power usage was only 442 watts on average. That means the weekly cost went down to:

 


((442 / 1000) * 60) * 0.12 or $3.18

a savings of $0.56 for this one system each week or a total of $29.12 for the year.  I have three systems that I tuned this way, so I’m hoping for a $87.36 savings from performing this tuning. Each system required about 30 minutes to tune, so I’ve made $58.24/hour from this activity. If you’ve read other posts, I do like to put a dollar figure on my time—you should too. Not many people can afford to throw away money like this and the PowerCfg utility, along with a watt meter, can help you better understand how your system uses (and abuses) power.

There are two additional command line switches you should know about when using the /Energy command line switch. The /Duration:Time command line switch changes the duration from 60 seconds to some other value. For example, if you want to change the duration to 120 minutes, you’d type /Duration:120. Longer testing times are often required when you’re trying to determine how an application is using energy. Take my advice and don’t set the duration lower than the default 60 secondsyou’ll be disappointed with the results.

The /XML command line switch outputs the data in XML format so that you can incorporate the information into a database. If you have a large setup, the XML format is absolutely essential. No one has time to look at individual HTML pages. Using XML output and a centralized database also makes it possible for you to look for organization-wide trends, which could produce even bigger savings.

The /Energy command line switch can also be used with the /Trace command line switch to trace energy usage without performing any analysis. This output isn’t as helpful or as accessible as using the /Energy command line switch alone. The output is an Event Trace Log (.ETL) file. To view this file, open the Event Viewer console found in the Administrative Tools folder of the Control Panel. Right click the Event Viewer folder and choose Open Saved Log from the context menu. You’ll see a dialog box asking whether you want to convert the .ETL file into the new format used by Windows 7. Click Yes. You’ll see a list of energy events like the ones shown here.

PowerCfg03

By carefully reviewing the events, you can discern energy usage patterns, filter data about specific events, and perform other analysis. However, this raw data is a little hard to use and the administrator would be better off generating the report, unless your organization has an application designed to analyze the raw data in some way.

So, how do you save energy in your organization? Do you rely on specialized tools such as a watt meter and PowerCfg? If not, how do you tune your equipment to deliver optimum service and minimum cost? Let me know at John@JohnMuellerBooks.com
