HF Radio used by Wireless Power SystemAssistant Professor Marin Soljacic from the Massachusetts Institute of Technology is one of the researchers behind work that could enable electronic devices such as cameras, phones and MP3 players to be recharged using HF Radio, eliminating the need for mains cables. He recently gave an interview to the BBC about Wireless Power delivery
that can be seen at The proposed system sounds reminiscent of the work by the world-renowned inventor, physicist, mechanical engineer and electrical engineer Nikola Tesla. In the BBC article an HF frequency of 6.4 MHz is quoted for the system, however, no mention is made of the total bandwidth occupied. This is an unfortunate choice of frequency since the HF radio spectrum (3 - 30 MHz) is a precious natural resource. It is the only part of the electromagnetic spectrum capable of sending low power signals around the world and needs to be protected against all forms of electromagnetic pollution. It is claimed the sytem would use "non-radiative" objects with so-called "long-lived resonances" and that when energy is applied to these objects it would remain bound to them, rather than escaping to space. However, the initial system is designed to cover a room and Marin Soljacic talks about adapting it to work in a factory. One wonders if in that scenario it would still be "non-radiative" ? It is to be hoped that if this system eventually comes to fruition alternative
frequencies will be used to ensure it doesn’t radiate an electronic
smog that fouls and pollutes the HF radio spectrum. Marin Soljacic received a BsE degree in physics from MIT in 1996, and a BsE degree in electrical engineering from MIT in 1996. He got his PhD from the Physics Department of Princeton University in 2000. After that, he was a Pappalardo fellow in the physics department of MIT. In 2003, he became a Principal Research Scientist in Research Laboratory of Electronics at MIT. In the autumn of 2005, he became Assistant Professor in the physics department of MIT. In 2005 he was the recipient of the Adolph Lomb medal from the Optical Society of America. His main research interests are in theoretical photonic crystals, and non-linear optics. He is a co-author of 53 scientific articles (published or submitted), and is a co-author of 15 patents pending (or issued) with the US patent office. Nikola Tesla The Tesla Wardenclyffe Project
