During the warm summer months we use fans to cool ourselves off. I have never liked air conditioning and would prefer to drive with the windows down than turn on the air conditioning in the the car. I love the feel of the air from the fan and the noise it makes and I associate these feelings and sounds with warm summer days and nights.
The fan started as a simple hand held instrument that people waved near their faces by quick rotations of the wrist. Simply creating wind by moving air with a a flat rigid sheet makes you feel cooler. This idea started in someone's mind. The person had to have tried it and and then shared the idea with others when it was found to be so useful. The idea would have then gained momentum as more and more people got involved and more efficient designs and applications were then thought into being.
With the discovery of electricity it was only a matter of time before an electric fan was designed.
Let there be Fan!
In this hub I would like to give you, the reader, the experience of the thinking involved in designing an electric fan. I want you to use your imagination and imagine yourself as an inventor. All you have is a hand held fan perhaps the one that folds up. Meditating on this fan is your job to think an electric fan into existence.
The electricity will power a motor so you won't have to use your hand to move the air any more. So how do you attach the motor to the fan you are holding? Is the shape conducive to attaching it to a motor?
Air is medium like water so you might be tempted to think about how man went from hand held oars to propellers to move a boat through water. The idea of a rotating propeller might surface as a result.
With your mind fixed on a propeller attached to a motor you might then ask yourself how many blades would your fan design need in order to be most efficient.
You would set up experiments to test each factor that you think might affect the efficiency of your design. And that is exactly what was done. Some of the factors tested simply had no bearing at all but the ones they found to be absolutely crucial were:
- The volume of air moved by a blade depended directly on its surface area.
- The speed of the wind from a blade depended on both the angle of the blade and its speed.
They also found through experimentation that having more blades did not increase efficiency but actually lowered it because of the increased power required to move them and each blade was travelling in the wake of the one before it.
Having fewer blades meant that the blades would have to turn faster in order to move the same volume of air and that would mean a noisier fan. A single blade fan was found to be the most efficient but it would have too large a diameter.
They settled upon the multibladed design which we have grown used to. This came about after much thinking and experimentation. The main reason for choosing the multibladed design was in fact to keep the diameter small enough so that the fan would be easily portable.
The subject of this article is the electric fan but every thing you see around you once started as an idea and this same process of thinking and action has made it manifest physically in the world.
Many ideas surface in the mind but only those ideas we focus our thinking upon and give sufficient energy to that actually make it to the action stage. When thought is actioned then that thought takes physical form. This is the essence of creation and how Man continues to share his thought by the physical representations of those thoughts he passes down from generation to generation.
Like the fan the aeroplane started in the mind of a man who thought about flying. Unless you can imagine it then you are never going to conceive it. The first step in any creation is the imagination and that is what all the great inventors had oceans of.
Hypnosis is a tried and tested way to fan creativity because it it nurtures the imagination and cultivates that all important connection with the subconscious. By learning the Art of self Hypnosis you can deliberately choose to nurture your creativity and open yourself to new possibilities that you may not even be able to imagine right now!
