wi-tricity

Published Categorized as radio, technology

If saw wi-tricity in Howth in the mid 1980’s. a Hobbyist radio engineer Frank Decker from Grace O’Malley showed me and my twin brother how to use incandescent light bulb as a dummy load for a FM radio transmitter. [for the non geek readers why dummy load? its like taking full output and soaking it up immediately ] so this wasn’t wireless. a PL259 connector with coaxial cable patch would be soldered on to a 15W light bulb or a 40W light bulb. Too much power and the bulb blows.

So the real interesting stuff happens in the earlier stages of the transmitter. A fairy light bulb (think Christmas tree lights) has a screened cable loop of 1 centimeter diameter connected to the two points of the little bulb (which are hard to find in June) the the loop on the bulb is placed on the coils of the early stages and the transmitter is tuned up by light. These little fairy lights when placed in the air near the output stages would light up! then modulate the transmitter with “California Über Alles” by the Dead Kennedy’s and blow the whole Christmas tree set of lights.

Massachusetts Institute of Technology researchers made a 60-watt light bulb glow by sending it energy wirelessly — from a device 7 feet away — potentially heralding a future in which cell phones and other gadgets get juice without having to be plugged in.

The breakthrough, disclosed Thursday in Science Express, the online publication of the journal Science, is being called “WiTricity” by the scientists.

this method of radiation to light is now deployed in childrens toys.!

these memories of mine help me form opinions about technology and its advance in the name of mankind making money. When UMTS towers are placed beside homes and schools i think of holding these fire cracker fairy lights. I also recalled RF burn and RF blindness to a rep from H3G doing some after care community relations having sited a tower beside a school, that the locals forced them to remove through civil militancy.

This must read as very worrying news for 1-2% of the population that are electro sensitive. more EMF smog. If my neighbours get this inside their walls, i can kiss goodbye to shortwave listening.
