<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">Want to save the Earth? Easy, just buy a couple of ice trays. To the long list of human inventions that are wrecking global climate—the internal combustion engine, the industrial era factory—add the automatic ice maker. <span style="color: #3366FF">A scientifically ignorant statement. Although true that the compression of air sheds heat into the atmosphere to make ice, when the ice leaves the fridge it absorbs equal heat from the atmosphere ... melting being the opposite of freezing ... and equilibrium is again restored. Plus, it takes the same compressor to freeze cubes in the old fashioned ice tray as it does in the icemaker bin.</span>

Climate modelers have long known that households are far bigger contributors to global warming than most laypeople realize. <span style="color: #3366FF">Climate modelers have also built models which make inaccurate predictions ... without exception.</span> For all the blame tailpipe emissions take for escalating temperatures, homes and office buildings are actually the single largest contributor to greenhouse gasses. One key reason is the 100-plus million refrigerators in America's 111 million households. <span style="color: #3366FF">Didn't the article start by saying we should use refrigertaors?</span> According to the Department of Energy, the standard fridge sucks up about 8% of the electricity used by all homes—a pretty big share given the dozens of big and small appliances and electronics that are also drawing juice. <span style="color: #3366FF">And in spite of the third world use of refrigeration exploding in the last decade ... global temps went down.</span>

That energy gluttony has always made refrigerators prime targets for design improvements and most of the big manufacturers have made real progress in squeezing every last bit of efficiency out of their machines—especially since they know that cash-strapped consumers are paying closer attention than ever to energy-consumption ratings before making their purchasing decisions. <span style="color: #3366FF">So ... the free market is fixing the problem which statism can't? A Freudian slip?</span> The problem is, those ratings are not always terribly precise. <span style="color: #3366FF">But they are set by the same modelers working for the state?</span> In general, refrigerators will simply get a gross energy-use score, without anyone examining just which components in the overall machine are driving the numbers up or down. <span style="color: #3366FF">So the statists demanded that the state set a number, and then it's the market's fault that the state took the funding and produced junk science.</span> Ice makers have thus long gotten a pass, but analysts at the National Institute of Standards and Technology (NIST) recently decided to give them a closer look—and they got a surprise when they did.

According to the just-released findings, the average ice maker in the average fridge increases energy consumption by 12% to 20%—a whole lot of juice for an appliance that is in operation 24 hours a day from the moment you first plug it in till the moment you replace it a decade or more later. The reason that number was so unexpected was that the large majority of refrigerators are refrigerator-freezer combinations anyway—which means they're freezing water and making ice no matter what. <span style="color: #3366FF">In a lab, perhaps. In reality, they all have an auto shutoff when the bin is full ... and again, how would making the same amount of ice in old trays work better? Answer is that only a moron would expect that it would. In fact, opening and closing the freezer everytime one needs ice would increase energy use.</span> So why should the simple business of automating the process be so energetically expensive?

The answer, it turns out, is the tiny motor inside the freezing system that's used to release the bits of ice from the mold and dump them into a tray. A motor that is designed to operate in so cold a setting needs an internal heater to keep it from freezing up, and heating elements require a lot of power—in this case, roughly three fourths of the total additional energy the ice maker uses. <span style="color: #3366FF">That ios a ridiculous assumption as the heater would only have to heat the blades to 33 degrees</span>

Certainly, on the list of big things that are responsible for global warming, the icemaker ranks a good ways behind the coal-fired power plant, but averting climate catastrophe is often a game played in increments and inches, and every kilowatt hour helps. NIST is thus urging refrigerator manufacturers to look closely at the design of their icemakers, insisting that there are "substantial opportunities for efficiency improvements merely by optimizing the operations of the heaters." <span style="color: #3366FF">Anyone who believes new side by side refrigerators use more energy per cubic foot of storage than older units is a buffoon.</span>

That appeal to reason, NIST officials hope, will be enough. But just in case it isn't, the Department of Energy has announced that it intends to add 84 kilowatt hours to the efficiency rating of every refrigerator equipped with an icemaker. Consumers will feel that fact in the wallet—and if manufacturers don't scramble to improve their numbers, they soon will too.

Another example of the nutty 28(?) percent!

I think it's down to the nutty 20%.

my new fridge makes small ice cubes and takes very little energy to produce them. I have also noticed that if I fill my tank when it's only about half empty, it costs a whole lots less. It's these little things that add up if we all would pitch in and use our heads that can bring about real change.

In January it was a daily average of 17 degrees here.

By April it's up to an average temperature of 54 degrees.

At this pace it will be up to a daily average of 313 degrees by Christmas.

I wonder what the IPCC would pay me for my scientific model?
