Bigger RFI threat than BPL, IBOC?
Greetings;
Thanks for bringing this to our attention. If the energy stays near the coil, how would it interfere with HF? It would be interesting to learn more about the science behind this research. It would be interesting to have a shortwave radio at the lab and hear what happens.

Since HF radio is electromagnetic propogation, there is no way that a "magnetic" energy transfer would not interfere. After all, you are not receiving electricity on your HF radio, but electromagnetic waves ("magnetic") which are turned into electricity by your receiver. |

How are you going to get it to "stay near the coil" and still couple any energy into the other end? In fact, at that frequency it is impossible to get much efficiency, so that majority of the RF will be radiated. According to the article, the made id a whole six fet. To double that distance, they would have to put four times the energy into the system. There is enough inefficient crap on the market already. If that idiot can't remember to charge his cell phone, then he doesn't need it. If he's that absent minded, he shouldn't be allowed to drive, or maybe be allowed out of his house. This smells of a MIT practical joke, to see how many idiots bite before someone blows the whistle, like: http://www.dhmo.org/ It would be interesting to learn more about the science behind this research.

"Bruce Atchison - author" wrote in message .. . [snip] It would be interesting to learn more about the science behind this research. Check out your local library. Look for radio related electronics textbooks, the Radio Engineer's Handbook, the Radiotron Designer's Handbook and similiar books. The ARRL handbooks cover this concept well without a huge amount of math. It would be interesting to have a shortwave radio at the lab and hear what happens. Many SW radios -- especially portables -- will overload on strong signals. An SW radio overloaded by a nearby battery charge broadcaster would be blocked out. The effect would be the same as with some car radios which overload near broadcast towers. Frank Dresser |

It would be interesting to learn more about the science behind this research. It would be interesting to have a shortwave radio at the lab and hear what happens. This is a workable concept over a short distance; the shorter the better. A practical example would be a induction stovetop where the pan is right on the other side of a ceramic top from the induction coil. Many people have these but a drawback is that you have to have iron, copper or steel cookware. Glass or ceramic pots and pans won't work. The idea is to put all the power into an induction field and not radiate the energy to a greater distance than 1 wavelength of the operating frequency. Energy in a local induction field does not leave the local circuit. A local power induction field could easily cause a radio not to function and even damage it. This is not workable over the distance of a house. The power induction field would have to saturate everything in the house including people. Currents would flow in any conductor and heat it up. -- Telamon Ventura, California |

Could cook some eggs on the hood of your car on a cloudy day maybe. I remember them telling me in school - GO BADGERS! - that in order to have a field that was not static there had to be both H and E components. Is it possible to have a field in the MHz range that only has one component? either B or E? I don't think so. B=Mu*H NEO |

I wouldn't even want to date Paris Hilton.Lets me see can I can drum up
some kind of a good old, old, old black and white movie on Radio tb to watch.Doggy, she is sleepin down between my legs, as usual. cuhulin |
