Microsoft should stick to writing crappy softwa
http://moneycentral.msn.com/content/...4.asp?GT1=6704 Here's my favorite energy saving tip from the article: 'Replace incandescent bulbs with compact fluorescents; they produce the same light but use a fifth the energy and heat ' I wasn't aware that light bulbs used heat to operate. But if this is true, wouldn't you want to install bulbs that use more heat in the summer, and then in the winter install bulbs that use less heat? I wish someone would have told me that all I need to do to keep my house cool was turn on every light in the house. Also, because the debate about shading the condensor is simply fascinating stuff, here is MS's take on it: 'Plant trees or shrubs to shade air conditioning units, but not block the airflow. A unit operating in the shade uses less electricity. ' |

They do "produce" heat. In the winter, I'm less careful about turning lights off that are not being used. The light does convert to heat energy, so it will in turn heat the house and not be wasted. Of course this was probably re-written by some software babe, not from the original tech writer. |

Everything you posted above is absolutely true... Perhaps you need a bit more explanation, so here it is. Incandenscent lights turn MOST of the electricity they use into light of a frequency that we cannot see. That light, which we call "infrared" just bounces around in a room and heats up the place. Fluorescent converts MORE of the electricity into light that our eyes respond to. Consequently,, if the goal is to "see", fluorescent is the better choice. It is also more costly to buy... so it is a tradeoff.... If you use incandescent in the winter, when you need heat, you are "helping" your furnace. If you use fluorescent in the summer when you need "cool", you are helping your air conditioner..... However, you have to weight the COST of the fluorescent lights against the SAVINGS in electricity used. Personally, I use a LOT of incandescents inthe winter and unscrew a LOT of the bulbs in the summer...Just my method..... Regarding shading the airconditioner...... Direct sunlight puts about 1000 watts per square meter onto the earth. That means that in the summer (or winter ), not only is the outside of your air conditioner condenser heated by the surrounding air , but it ALSO get an extra 1000 watts or so from continuous sunlite.... 1000 watts is about 5000 BTU, so it would take a 5000 watt air conditioner running full time just to get rid of the heat from direct sun radiation which shines on your outside consdenser unit.... Roughly 12 cents an hour extra, during daytime.... So, if you plant a screen , like a bush or tree, in from of the condenser, you get rid of this undesired direct heat source..... ........ if you block the air flow, tho, you are screwing things up... The preceeding explanation is exactly accurate, although it does not include several other factors which merely confuse the issue for the novice........ If one wishes to discuss in detail some of these factors, and get into depth,..... let's do it by email...... Andy Registered PE in Texas , MS, BS, GMDSS, NCE, etc |

Although very poorly worded...I think that was the intended point of the
post. No, actually it was not. The article says that flourescent bulbs USE LESS heat then incandescent bulbs. Which therefore means that incandescent bulbs USE MORE heat. Which means no one needs an AC unit, all they need to do is replace all the bulbs in their house with 500 watt halogen floodlights, and soon the indoor temperature will drop, because the halogens are using up all the heat in the house. Or at least, thats the theory Mr Gates people profess. As far as shading the condensor, I don't know either way, but there have been fierce battles about it over in another group whose name I won't mention here. |

I am not a A/C guy but it happened at work and this is the expalantion they
gave us: THere is a fixed temperature difference between the outside coils and the inside coils. As the outside coils get hotter so do the inside coils but they always maintain the same delta temperature. To cool the inside air, the inside coils have to be cooler than the inside air. IF the outside coils are so hot that the inside coils are only at 70 degrees than the cooling effect for the inside air will be minimal (less effiecient). At work they said the rooftop coils were sitting at 150 degrees. Hence the lack of cooling. Not sure I believe them. SO if you can keep the outside coils cooler, the inside coils will be cooler and you will consume less electricity. "Rick" wrote in message nk.net... "Doug Kanter" wrote in message ...

![]() "Red Cloud©" wrote in message Many thousands of years ago, I worked at a Steakhouse. The rooftop airconditioner was inadequate and old. During very hot weather, some of us would take turns up on the roof, squirting the coils with a garden hose. It made a BIG difference in the ability of the unit to cool the restaurant. We have a similar situation with the outdoor heat exchanger for our air compressor at work. (150 HP). During the hot weather it was getting marginal and causing compressor shutdown. So, some brilliant guy set up a lawn sprinkler under it. Cooled it down quite a bit, but with too much force, it also bent some of the fins reducing air flow. It is better now, after somebody laid under it and straightened fins for a few hours. |

So, considering all this information, which is intuitive, I wonder why HVAC
companies don't either sell (and make money on) or recommend at least a cover mounted a few feet over the top of AC units, or least a section of fence or something on the sunniest side. |

The first sentence has two components but whoever wrote the sentence acted as if it were one component--energy and heat. Nonetheless, just about every thinking person with English as a primarily language would know what the sentence intended. AC people like to argue about the effect of shade, focusing only on air temperatures. Apparently they never stood outside in the boiling sun or compared temperatures in houses that were fully illuminated by the sun with house that were shaded by trees. |

You know there is no such thing as Light.. There is just the absence of
Dark! Universal Theory of Dark For years it has been believed that electric bulbs emitted light. However, recent information has proven otherwise. Electric bulbs don't emit light, they suck dark. Thus we call these bulbs dark suckers. The dark sucker theory proves the existence of dark, that dark has mass heavier than that of light, and that dark is faster than light. The basis of the dark sucker theory is that electric bulbs suck dark. Take for example, the dark suckers in the room where you are. There is less dark right next to them than there is elsewhere. The larger the dark sucker, the greater its capacity to suck dark. Dark suckers in a parking lot have a much greater capacity than the ones in this room. As with all things, dark suckers don't last forever. Once they are full of dark, they can no longer suck. This is proven by the black spot on a full dark sucker. A candle is a primitive dark sucker. A new candle has a white wick. You will notice that after the first use, the wick turns black, representing all the dark which has been sucked into it. If you hold a pencil next to the wick of an operating candle, the tip will turn black because it got in the way of the dark flowing into the candle. Unfortunately, these primitive dark suckers have a very limited range. There are also portable dark suckers. The bulbs in these can't handle all of the dark by themselves, and must be aided by a dark storage unit. When the dark storage unit is full, it must be either emptied or replaced before the portable dark sucker can operate again. Dark has mass. When dark goes into a dark sucker, friction from this mass generates heat. Thus it is not wise to touch an operating dark sucker. Candles present a special problem, as the dark must travel into the solid wick instead of through glass. This generates a great amount of heat. Thus it can be very dangerous to touch an operating candle. Dark is also heavier than light. If you swim just below the surface of a lake, you will see a lot of light. If you swim deeper and deeper, you notice it gets slowly darker and darker. When you reach a depth of approximatley fifty feet, you are in total darkness. This is because the heavier dark sinks to the bottom of the lake and the lighter light floats to the top. The immense power of dark can be utilized to man's advantage. We can collect the dark that has settled to the bottom of lakes and push it through turbines, which generates electricity and helps push dark to the ocean, where it may be safely stored. Prior to turbines, it was it was much more difficult to get dark from the rivers and lakes to the ocean. The indians recognized this problem, and tried to solve it. When on a river in a canoe travelling in the same direction as the flow of dark, they paddled slowly, so as not to stop the flow of dark; but when they travelled against the flow of dark, they paddled quickly so as to help push the dark along its way. Finally, we must prove that dark is faster than light. If you were to stand in an illuminated room in front of a closed, dark closet, then slowly open the closet door, you would see the light slowly enter the closet; but since the dark is so fast, you would not be able to see the dark leave the closet. In conclusion, I would like to say that dark suckers make all our lives much easier. So the next time you look at an electric bulb remember that it is indeed a dark sucker.

Switching over to a lot of incandescents in the winter is basically the same as deciding that you are going to perform a portion of your home's heating with electrical resistance heating. Just like many others, I don't get as concerned about leaving lights (incandescent or fluorescent) turned on in the winter as much as I do in the summer. The heat from lights in the summer is an extra burden placed upon the AC system. But I would never intentionally use lights for heat, except in an emergency. If a gas furnace fails, the house can often be kept quite comfortable by leaving on all lights, TVs, PCs, etc. Leave the furnace fan running continuously to create a few extra BTUs and to help circulate heat somewhat uniformly. Operating a couple of small electric heaters may be necessary for a reasonable comfort level. This all depends upon current outdoor temperatures. Filling tubs and sinks with gas heated hot water adds more BTUs. This whole process is expensive, but it works in an emergency. But wasting electricity on a routine basis to help heat the house is a very expensive source of heat. |
