History of Air Conditioning

It is a wonderful thing to be able to flip a switch, and have an entire room cooled off through air conditioning. Portable room air conditioners make sense when you wish to cool certain parts of your home, office, or covered outdoor living spaces. Air conditioning is commonly found in buildings today, but it was not always the case throughout history.

Wealthy ancient Egyptian families could enjoy the cooling benefits brought from aqueduct water that traversed the insides of walls in buildings. Water was an expensive commodity in that hot region of the world, so only the rich could afford this luxury. Medieval Persians made use of wind towers and cisterns to cool their buildings. Wind would be captured in the wind tower, and it was then directed over the water in the open cistern, which would evaporate and cool the ambient temperature inside the dwelling.

Later on, the idea that liquefied ammonia, when it evaporated, could cool the air was thought up by British scientist Michael Faraday in 1820. In America in 1842, Dr. John Gorrie created a machine to make ice, and he used the ice to cool the air in his hospital in Florida.

Industry was the primary reason that air conditioners were created around the turn of the last century in the United States. Willis Haviland Carrier created the first electrical air conditioner in 1902, which was used to cool and dehumidify the air in a printing plant. The term "air conditioning" was coined by American Stuart W. Cramer in 1906, who came up with a way to add moisture to the air, which was crucial in his textile manufacturing mill.

Toxic gases were used to run the early air conditioners, but Thomas Midgley, Jr. created Freon refrigerant in 1928. Unfortunately, he did not know that Freon is bad for the ozone, and recently newer refrigerants have been developed that are safer for the environment.

Air conditioning is not only used today to make our homes and other buildings more comfortable. You will find air conditioning used in land, water and space vehicles. Air conditioning is used to also filter out bad particles in the air, such as in hospital operating rooms. If you have allergies or asthma, air conditioning can help remove the pollen, dander and dust that causes these conditions to flare up. The elderly can also be at risk if they are in a too-hot building, so air conditioning can be crucial for their well being. Some air conditioners are also dehumidifiers, which take the excess moisture out of the air to make you more comfortable in terms of your temperature. Today we are lucky that a great air conditioner is your answer for cooling comfort.

Shibari - Body, Mind, Spirit

Shibari (.a.k.a. "Japanese bondage" is an ancient, Japanese, integrated concept of body, mind and spirit.

The objective is to unlock erotic energy through trance or trance-like experiences.

Trance (a different level of awareness) is being achieved through a refined mix of atmosphere, ritual, meditation, love, techniques and intensity of the situation.

Most forms of oriental lovemaking are hardly ever straightforward sexuality, but an intriquing game of exploration and challenges and a delicate combination of subtlety and expliciteness.

Shibari is no different.

What is trance?

Trance is a situation where one is so dedicated to and concentrated on one specific goal or situation, that - through blocking out everything else - the spiritual capacities of the mind are eniterly dedicated to that specific activity. This opens the mind to be able to experience - and use - things it never could under "normal" circumstances, since the brain will be too distracted and too busy.

Certain hormones - endorphins especially - play an important role in trance. Endorphins (morfine-like amino acids produced by the body) are the key factor here. Endorphins are known as the "mood chemicals" in your body. They create your moods, all of them. They come in complex cocktails and also serve other purposes. For example, they are a natural painkiller. Experiencing high doses of endorphins release is called an endorphins rush. This is known as the "runners' high" in athletics and as "subspace" in power exchange activities.

A combination of endorphins, dopamine (known as "the lover's feel good hormone"), enkapheline and adrenaline releases creates "super awareness" and this is the key factor in creating trance. Since experiences such as fear, anxiety, stress and physical impulses such as pain all cause the release of high doses of adrenaline and subsequently endorphins - these impulses are being used to allow you to climb the first steps of the trance ladder. Endorphins have a "sister-hormone" called enkephaline, which works on the spinal cord in the same way enderphines work on the brain.

Since mood is important atmosphere is important, which is why - in Shibari body mind spirit terms - a lot of emphasys is being placed on preparation and the physical area. For this, such things as candle light, aroma therapy (incense or evaporating essential oils), bathing and other rituals and techniques are used to create "makama" - the "circle" (area), the physical area where both partners will experience their intens lovemaking. meditation helps to focus the mind and eventually Ki energy exchange is being used to further enhance the bonding between partners and the forces of gravity and sensory deprivation techniques are being used to create full trance.

Erogenous zones

There is a widespread misunderstanding: "erogenous zones are directly connected to the genital area and other primary sex-identifying features (such as the breasts)". Fact of the matter is that some 25 percent of the body surface (slightly more on the male body) can be identified as an erogenous zone. And the brain no doubt is the largest sex-organ. Erogenous zones are usually best stimulated through gentle massage, but they are also very receptive to other forms of stimuation, for example pain (if you are into that), or bondage.

The seven patterns of passionate lovemaking

By gently - or more strongly, in order to introduce the element of mild pain - pressing your finger nails into the fleshy parts of your partners' body you can not only leave temporary marks but doing this can also be an erotic game by itself. To do so, even and symmetric patterns are your best choice. This will not only indulge her lust, but it will also leave something to remember for a few hours a maybe a day or two, an effect that - more intensly - usually is also the result of whipping and caning.

Ropemarks are often an essential part of bondage. In a Shibari body mind spirit context they play a role, similar to other ways of leaving lovemarks.

In its original form these patterns should follow specific designs and all serve specific purposes. The idea is to leave physical marks that will function as a "tell tale", which - for example in ancient India - forced the "marked woman" to hide these marks since they indicated lustful, wild love. The more intens the temporary mark, the more intens the lovemaking had been. Complicated, repeated combinations of the seven patterns would indicate that the woman had really suffered during the lovemaking and the complicated patterns make it clear that she had to remain still during a long foreplay, while pain-impulses and excitement increased her lust.

The bite of love

Teeth tenderly or not, sinking into the tender female flesh, is not just a scene taken from a Dracula movie. Many novels and poems tell stories about lovebites. And in fact, like whip marks, bruises and others, bite marks serve as something to remember, to be proud of, to relive the passionate night before - the pain, the extacy, the lust, the love and the intimacy.

The Kama sutra again is one of the very few sources that describes the combination of marking and pain impulses during lovemaking. Unfortunately, although various other patterns are mentioned, they are not described in sufficient detail to reconstruct them. Various different flower patterns are mentioned for example. These must be combinations of teeth and nail imprints.

The magic of knots

The magical power of the knot is as old as mankind. You will find references to the magical power of the knot in almost any ancient culture, be it Babylonic, Celtic, Oriental, Hermetic, Wicca, Voodoo or other.

Love magic - and there are many forms of that - almost always involves the use of knots and, of course, rope. Actually, we still have some of that left in modern times. Tie a knot in your handkerchief so you will remember something really important

How does it work?

Magic is all about manipulating the energy of life. This energy is called Ki in Japanese, Chi in Chinese or prana in Sanskrit (the ancient language of India, still used in yoga for example). Conciously tieing one or more knots in a rope is a way to bundle this energy and store it there. Of course this energy will not make your car run. Neither will it make the lights go on. But it will be more than enough to have its influence on the subtle network of Ki energy exchange, that is everywhere.

In Shibari these "energy loaded" knots and ropes will replace the heart and hands of the giver and as such will contribute to the entire physical and spiritual experience. They enable the giver to "still be close to the recipient", even when physically not around. The interaction between the giver's energy - temporarily stored in the knots - and the pressure points on the Ki meridians in the recipients' body is what will release very powerful sexual and spiritual experiences.

Sexual energy is one of the most powerful manifestations of Ki energy. This is the reason why we still refer to whatever happens between love partners as "the magic", "the spark" or "the energy".

Universal love magic

The use of rope and knots, when working with sexual energy, is universal. In ancient Babylon (in the middle East) seven knots were tied in a rope to invoke love. Wicca has a similar tradition of making three knots in a rope for the same purpose (sometimes with an almond - the "love nut" - inside each knot). African Voodoo works with either seven knots in a rope or with dolls, tied to each other, to invoke love, the Kama sutra speaks of female love partners, suspended in rope to enhance their sexual energy. These are just a few of many examples.

Is all this strange? Actually not. There are over 50 erotic pressure points (Tsubo) on the human body, each as powerful as the clitoris or the nipples. And there are another 60 hormone-releasing pressure points along the spine, many of which have an erotic/sexual function. Ropes and knots will stimulate all these directly and energy, bundled in a knot, will only enhance their effect.

Dutch former journalist and government spokesman Hans Meijer is the author of the groundbreaking "Shibari Fumo Ryu" series of e-books, the first ever books outside Japan and written in english about Shibari techniques.

Is It Legal to Hack Your Wireless Network?

Once upon a time there was no choice when it came to your phone service. not only did you have to get your service through Bell systems, you had to rent the equipment from them too. Yes, you had to actually rent the phone that was plugged into the RJ-45 on your wall. A 1968 case where Carter Electronics took on Bell systems resolved that problem when a judge ruled that third party equipment can be plugged in and used on the network that Bell systems maintained and provided service on. A whole new communications industry was born and consumers were free to choose which equipment they wanted to use for communications.

The Bell system companies dragged their feet for many years after the Carterphone decision, still requiring customers to rent their equipment up until consumers fought them well into the late 70's. Even through that battle, we are still retreating back to the era where our communications options are becoming increasingly controlled in other arenas. Consumers are forced into contracts they don't want to be locked into, and to use phones only supplied by our wireless providers, Shouldn't the 1968 Carterfone decision make a difference in the wireless industry? Because of this case, shouldn't I as a consumer have the ability to use whatever equipment I want on a wireless network? How about a cable network? The Internet?

In the Carterfone case, the FCC cited their decision which stated that a subscriber's right to use the network in ways which are "privately beneficial without being publicly detrimental" applied to ALL TYPES OF equipment. What does this mean? It means that everybody who subscribes to a service is able to use their own equipment in a way that benefits the subscriber as long as no other subscribers are affected. without the Hush-A-phone or Carterfone decisions, companies like AOL may have tried to rent us "the only computer that will work on the Internet." Electric companies could make a case for dictating which light bulbs you use. Gas companies might force you to buy their brand of furnaces.

Still today, most cable companies require their subscribers to rent a cable box you could buy your own. SIM card technology provides the ability to switch wireless phones whenever a person wants to, yet providers such as Verizon and Alltell fail to embrace this technology, forcing consumers to sign a new contract or spend exorbitant amounts of money to simply switch

As consumers we need to start demanding better of our service providers. at&t and Sprint allow us to use SIM cards with most of their phones. We can go online and purchase a phone off Ebay, pop in the SIM card from an old phone and you're ready to go! There is alternative equipment that can be used on cable networks, but nobody really challenges cable companies when it comes to actually using it. We all just keep our mouths shut, dig in our pockets and fork over the extra $5 a month to rent the box. We have come along way since 1969. There are multiple phone carriers, wireless companies, and cable companies to choose from. But we can do better than being roped into paying a subscription fee on items we can buy ourselves or signing 2 year contracts just to get the latest smartphone. Remember it's supply and demand. Ultimately it should come down to the consumers wants and needs. not what the provider is willing to give us.
