Wireless transmission of power

There was an article in Science News (I think it was this week, though the way I read it I just pick up whatever's sitting on the kitchen table when it happens to catch my eye) about developments in the wireless transmission of power, via a magnetic field over a short distance that isn't harmful to humans and other living things (assuming you don't believe the whole anecdotal argument about how unnatural magnetic fields harm the organism). The experiment described managed to power a light bulb remotely, and the immediate direction of development is for powering wireless devices, but the practical possibility of such a thing also hearkens back to the proposals of Nicolai Tesla for sending pulses of large amounts of power over great distances, which for some reason I translated into my dream imagination as fireballs conveyed by catapult from mountain top to mountain top... When I first came to PG&E I worked with a Portuguese electrical engineer named Luis Ferreira who thought Tesla had been taken down in a criminal way by my namesake, Thomas Alva Edison, and loved describing his proposals as if they were in fact good solutions to the distribution of electrical energy (as the Science News report mentions, corporate support of Tesla's work was pulled when the investors realized Tesla had no way of billing for the energy he wanted to send abroad...)

Meanwhile, my last dream of the night was about giants, one-eyed giants like the ones in the Lion, Witch and Wardrobe movie from Disney (I still want to delve into Matthew Barney's role in the imagery of that film) rampaging around in houses, people including myself cowering and unable to do anything about them. I woke up when it looked as though the giant was going to go after Elena, who was with me -- the first time I think that I've seen her in my dreams.
