The tangle of cables and plugs needed to recharge today's electronic gadgets could soon be a thing of the past. US researchers have outlined a relatively simple system that could deliver power to devices such as laptop computers or MP3 players without wires. The concept exploits century-old physics and could work over distances of many metres. Although the team has not built and tested a system, computer models and mathematics suggest it will work. "Resonance" [is] a phenomenon that causes an object to vibrate when energy of a certain frequency is applied. "When you have two resonant objects of the same frequency they tend to couple very strongly," Professor Soljacic [explained]. Resonance can be seen in musical instruments. "When you play a tune on one, then another instrument with the same acoustic resonance will pick up that tune, it will visibly vibrate," he said. Instead of using acoustic vibrations, the team's system exploits the resonance of electromagnetic waves. Electromagnetic radiation includes radio waves, infrared and X-rays. The team from MIT is not the first group to suggest wireless energy transfer. Nineteenth-century physicist and engineer Nikola Tesla experimented with long-range wireless energy transfer, but his most ambitious attempt - the 29m [it was actually 187 feet] high aerial known as Wardenclyffe Tower, in New York - failed when he ran out of money. A UK company called Splashpower has also designed wireless recharging pads onto which gadget lovers can directly place their phones and MP3 players to recharge them.
Note: What the article fails to mention is that Tesla's experiments previous to the 1903 Wardenclyffe tower were quite successful, so much so that J.P. Morgan was willing to pour huge amounts into the tower. When he learned, however, that Tesla's intention was to make energy available free to the public, he pulled the plug on the project and many of Tesla's amazing inventions were buried and erased from the history books.

Throughout the years that I've written about the potential health hazards of cell phone radiation, I've seen a lot of products promise protection from the radiofrequency (RF) signals that our wireless devices emit. They've ranged from the useless gold-lined radiation "shields" to Pong's more respectable line of phones cases that promise to refocus RF energy away from your head. At CES 2018, a company called Spartan grabbed that promise of protection and took it below the belt with a line of men's underwear. Spartan's boxer briefs claim to block 99 percent of cellphone and Wi-Fi radiation with pure silver fibers woven into the cotton fabric. That Spartan is focused on protecting your balls is significant. Though brain cancer tends to dominate the debate over whether wireless signals are safe, other studies have suggested that cell phones decrease male fertility. Some health advocates who have long been involved with the debate, and even some government agencies (most recently, the California Department of Public Health), recommend that men not carry their phones in a pants pocket to reduce radiation exposure to your nether regions. If the potential danger concerns you, most of the typical recommendations like using a headset, texting instead of making a call (a lot of us already do that) and not sleeping with your phone don't cost a penny.
Note: In 2017, after years of public pressure and a lawsuit, the California Department of Health released guidelines on the health risks of cell phone use. For more along these lines, see concise summaries of deeply revealing health news articles from reliable major media sources.
Imposing roughly the same cautionary standards for cellphones as for fatty food or sugary soda, this city -- never shy about its opinions -- voted on [June 15] to require all retailers to display the amount of radiation each phone emits. The law -- believed to be the first of its kind in the nation -- came ... amid opposition from the wireless telephone industry, which views the labeling ordinance as a potential business-killing precedent. But the administration of Gavin Newsom, the city's ... mayor ... called the vote a major victory for cell phone shoppers' right to know. Under the law, retailers will be required to post materials -- in at least 11-point type -- next to phones, listing their specific absorption rate, which is the amount of radio waves absorbed into the cellphone user's body tissue. These so-called SAR rates can vary from phone to phone, but all phones sold in the United States must have a SAR rate no greater than 1.6 watts per kilogram, according to the Federal Communications Commission, which regulates the $190 billion wireless industry.
Three years ago, at the age of 48, Camilla Rees had to leave her apartment in downtown San Francisco. Not because of the rent, she says, but because of the radiation. Her personal radiation meter -- yes, such things exist -- spiked after a lawyer couple moved in next door. Rees says she quickly lost her ability to think clearly. "I was unfocused, as if I had suddenly come down with ADHD. I would wake up dizzy in the morning. I'd collapse to the floor. I had to leave to escape that nightmare." Rees asked the neighbors if they had installed a new Wi-Fi router, and sure enough they had, on the wall near Rees' bed. Since then, Rees, a former investment banker, has been on a crusade against low-level electromagnetic fields, or EMFs, of all types, including the microwave radiation that flows from cellphones and cellphone towers. She co-wrote the 2009 book Public Health SOS: The Shadow Side of the Wireless Revolution, one of many recent books to warn against the dangers of EMFs, and founded the website electromagnetichealth.org.
