We are looking for an across-the-board solution for our present exorbitant consumption of gasoline and it seems as though there is none, at least for the present. We are looking at Ethanol additive to our present gasoline formulas, but this will only give us better miles per gallon and of course, much cleaner bi-products with its use. Ethanol becomes a temporary
fix…at best. The reason, of course is the need for the corn base sugars(and other similar sugar and starch crops) to produce it. It is a simple deduction that it will eventually begin to deplete the food stock of our nation and also hurt our exports of these grains. We could, with the anticipated increase in need of our corn crop, grow the extra acreage that
would be needed to meet any anticipated needs. We must keep in mind the amount of labor that would be required to accomplish this task. The question remains…Will the Ethanol approach keep the price below our present gasoline prices ?

Confabulations are an important part of life. They serve to heal emotional wounds or to prevent ones from being inflicted in the first place. They prop-up the confabulator’s self-esteem, regulate his (or her) sense of self-worth, and buttress his (or her) self-image. They serve as organizing principles in social interactions.

Father’s wartime heroism, mother’s youthful good looks, one’s oft-recounted exploits, erstwhile alleged brilliance, and past purported sexual irresistibility – are typical examples of white, fuzzy, heart-warming lies wrapped around a shriveled kernel of truth.

But the distinction between reality and fantasy is rarely completely lost. Deep inside, the healthy confabulator knows where facts end and wishful thinking takes over. Father acknowledges he was no war hero, though he did his share of fighting. Mother understands she was no ravishing beauty, though she may have been attractive. The confabulator realizes that his recounted exploits are overblown, his brilliance exaggerated, and his sexual irresistibility a myth.

Such distinctions never rise to the surface because everyone – the confabulator and his audience alike – have a common interest to maintain the confabulation. To challenge the integrity of the confabulator or the veracity of his confabulations is to threaten the very fabric of family and society. Human intercourse is built around such entertaining deviations from the truth.

Watching the news the other day, it occurred to me that people who have “words to live by” often begin to attack and even kill others. I thought back to my own angry youth, when I could easily use words to justify violent thoughts which might have become violent actions. Words are tools, and yet it seems that they can be more dangerous than gunpowder.

Imagine two men facing each other, pointing past one another. One is pointing at a tornado that is coming, and the other at a raging fire headed towards them. Each sees their own truth and is angry at the sight of the other’s hand. Each feels that the other’s hand is “wrong.” This may seem silly, but replace the tornado and fire with any modern issues, and the hands with words, and this scene describes how we often try to communicate.

Passive solar is a method of using the energy from the sun to heat a home. It is extremely popular because the process is free once a passive solar home is created.

Is Passive Solar A Viable Home Heating Option In Cold Areas?

Passive solar can be used to heat a home in colder areas, but you have to go into it with reasonable expectations. While the cold climate is a hurdle, the real issue is going to be the length of time the sun beats down upon your property. If your home receives only four or five hours of direct sunlight a day, forget it. You will never produce enough energy to keep the home warm for sufficient periods of time.

Passive solar design is very popular in warm to mild climates because it is more or less a free method for warming a home. The manipulation of the position of the home and placement of large windows in the south facing wall is typical strategies for dealing with the issue. Obviously, large windows in a cold climate are going to result in significant heat loss regardless of the quality with which they are built. So, what can you do?

There are two primary approaches to creating a passive solar design that works in the winter. One is the use of a large Trombe Wall and the other is the greenhouse approach. Let’s take a look.
