Electromagnetic (EM) energy comes from switching the positive and negative poles of a magnet backwards and forwards. It's how we produce electrical energy. EM energy as we know it is a vector form of energy, meaning the electrons associated move from one place to another.

Traditional EM energy has a wave form, like the waves of the ocean, or when, as a kid , you shook a rope up and down and made a wave that means. These waves are transverse, meaning that the wave's energy goes in an axis (up and down), while the wave itself goes perpendicular to that, forward along the rope or in the direction of the shore.

However James Clerk Maxwell in 1865, Nikola Tesla in 1899, and E. T. Whitaker in 1903 realized that there was an additional kind of wave present along with the normal transverse EM energy, referred to as longitudinal EM energy. This form of wave energy is mentioned as scalar energy (as opposite to vector energy), as the particles involved do not travel anywhere. An additional name given to the phenomenon is zero point energy.

Let me give you an instance: suppose you and your friends were lined up next to one another, all facing in the same direction, and the person next to you gives your shoulder a shove, not hard enough to knock you down, but sufficient to bump you into the person next to you. That person would bump the person next to them, and so on. What happened? Energy was transmitted along the line of people, but nobody actually went anywhere. You and your friends simply made a longitudinal wave.

Longitudinal waves are also named compression waves. One more image that might aid you to picture a compression wave is when you drop a pebble into water and the waves spread out from that. The pebble drops down (transmitting vector energy as transverse EM energy does); the longitudinal waves develop 90 degrees to the pebble on the surface of the water, moving a leaf up and down but never moving it away. It's not just the same, but hopefully you get the idea.

So where does such longitudinal (or scalar) EM energy come from? The theory is that when electrons become part of an electrical current in conventional (transverse) EM energy, the rest of the atom has an equal and reverse reaction in the other direction, to balance things out. The pebble drops down; the water rushes up to fill up the space. The two reverse reactions of the electrons and their atoms causes longitudinal EM waves to form, just as waves form after a stone drops into water.

Since the early twentieth century, several investigators have tried to develop practical applications of scalar EM energy including medical and health applications, home-based energy production and weaponization, with varying degrees of success. One of the most recent uses has been the scalar energy pendant reported to have some health benefits.

Green Energy Revolution: Energy Saving Devices
World today is experiencing energy revolution. Environmental issues are catching up and with the increased emphasis placed on preserving the environment we all need to play our roles in saving energy.

Vertical Axis Windmills - Find Out Some Of The Main Benefits Of Vertical Axis Windmills Over Horizontal Forms
Vertical windmills aren't such a recent concept. In fact, despite that we are accustomed to seeing horizontal axis windmills, the first windmills invented were the vertical ones. The first functional types were invented in the 9th century, but their design has changed very much over the years in order to get a higher efficiency from them.

The Use Of Renewable Energy Needs To Be Increased
The resources that have been used to empower worldwide economies are becoming extinct, causing fighting in the Middle East, and an accelerated international government power trip. The sooner every home owner and businesses makes the decision to begin using renewable energy, the sooner the world will be a more pleasant place.
