Wireless Electricity demonstration – Eric Giler
Though WiTricity uses two coils — one powered, one not, just like eCoupled’s system — it differs radically in the following way: Coils don’t have to be close to each other to transfer energy. Instead, they depend on so-called magnetic resonance. Like acoustical resonance, which allows an opera singer to break a glass across the room by vibrating it with the correct frequency of her voice’s sound waves, magnetic resonance can launch an energetic response in something far away.

Spirituality has a different meaning to each of us, it seems. A standard definition would be: “A sense of meaning and purpose; a sense of self and of a relationship with ‘that which is greater than self”.

BBC Horizon – Most Of Our Universe Is Missing
There was a time, not so long ago, when science seemed to understand how the universe worked. Everything us, the Earth, the stars and even exotic-sounding supernovae was made of atoms which were all created at time-zero: the Big Bang. In between the atoms was nothing, a void: quite literally, ‘space’. But recently things have started to unravel. There is, it seems, a lot more to the universe than meets the eye. According to the best estimates, we only really know what about 4% of it is made of. But if only 4% is made of atoms, what about the rest? The rest is made of mysterious entities about which very little is understood, with equally mysterious names: dark matter and dark energy.
