Intel Cuts Electric Cords with Wireless Power System
SAN FRANCISCO (AFP) - Intel on Thursday showed off a wireless electric power system that analysts say could revolutionize modern life by freeing devices from transformers and wall outlets.

Intel chief technology officer Justin Rattner demonstrated a Wireless Energy Resonant Link as he spoke at the California firm's annual developers forum in San Francisco.

Electricity was sent wirelessly to a lamp on stage, lighting a 60 watt bulb that uses more power than a typical laptop computer. Most importantly, the electricity was transmitted without zapping anything or anyone that got between the sending and receiving units.

"It turns out the human body is not affected by magnetic fields; it is affected by elective fields. So what we are doing is transmitting energy using the magnetic field not the electric field."

1. Kewl!
It would be great if one could do away with power lines, especially in certain areas. I'm thinking of areas hit by storms and electrical outtages. Would be a life saver in the wintertime or in tornado / hurricane season.

4. And less house fires and just so much.

2. efficiency?
25% loss to go just two feet?

5. Not efficient yet, but...
At MIT the students have a club where the real brainacs hang out on Friday night and invent. I had to great joy to be invited to their club just off of Mass Avenue and they had a field generator that was spookier than a sci-fi movie, but they were lighting up light bulbs and having a great time.

You hit on the drawback of the 25% loss, but this is a great step.

3. Magnetic fields are now completely safe?
The claim that the human body is not affected by magnetic fields is highly suspect.

6. It seems pretty safe.
Magnetic rather than electric fields? Even though they are part of one of the four universal forces.

I live close to the high power lines here in Southern California as I live up in the mountains right at the very edge of the Angeles National Forest. So I may not be around too much longer as my cells are being zapped by the electric fields. LOL.

7. Considering you're sitting in one right now,
I'd say they're pretty safe.

We evolved inside the Earth's magnetic field. They don't have any detrimental effect on any living things that I'm aware of.

9. Some people react to the dyes.

<snip>

On September 7, 1976, plaintiff went to the radiology department of Temple University Hospital to undergo the CT scan. Judith Hart, M.D., who had completed a residency in radiology and was then a fellow in neuroradiology, was to administer the test. Prior to performing the CT scan, contrast medium or dye had to be introduced into plaintiff's bloodstream. As Dr. Hart was about to inject plaintiff with dye, plaintiff explained to Dr. Hart that she had previously undergone tests that utilized dye and had suffered reactions including nausea, vomiting, hives and difficulty breathing. There were also discussions between plaintiff and Dr. Hart concerning plaintiff's choice as to whether to proceed with the test, plaintiff's anxiety about the test and the special precautions which would be taken by Dr. Hart. As a result of these discussions, Dr. Hart set up an intravenous line so that if a problem arose, drugs could *385 be administered quickly. Dr. Hart also administered a test dose of the dye. First, two drops of dye were released, and approximately five or seven minutes later, an additional eight drops were released. Almost immediately, plaintiff experienced difficulty breathing, tightness of the throat, pain, nausea, vomiting, hives and welts. Dr. Hart stopped the flow of the dye and administered epinephrine and benadryl. For the next 15 or 20 minutes, plaintiff remained in the radiology department under observation. At her own insistence, plaintiff then reported for a previously scheduled appointment with Dr. Cramer, another physician at the same hospital. After being examined by Dr. Cramer for an unrelated hand disorder, she returned to the radiology department. Dr. Hart examined plaintiff and advised her that she could leave the hospital. Plaintiff was then driven by a friend to her home in New Castle. Over the next 48 hours, plaintiff experienced vomiting, nausea and headaches. She had welts on her body for three days and hives for two or three weeks. In addition, plaintiff testified that she continues to suffer from headaches and nausea.

Much of plaintiff's testimony concerned her psychic activities and her inability to practice these activities following the CT scan. To read an aura, according to plaintiff, it is necessary to go into an altered state, a state of deep concentration. However, subsequent to the CT scan, whenever plaintiff entered this altered state she developed excruciating headaches. Consequently, she stopped reading auras. Because she no longer could read auras, she closed her office in Delaware and stopped assisting law enforcement officers. She was also unable to continue reading the auras of her husband and children. As a result, plaintiff holds herself responsible *386 for the death of her son in "an automobile accident that didn't have to take place."

Plaintiff's husband, Allen N. Haimes, D.D.S., also testified concerning the headaches experienced by plaintiff since she underwent the CT scan, the changes he observed in plaintiff and the effect these changes have had on the lifestyle of the Haimes family.

Plaintiff presented the deposition testimony of several witnesses in support of her claim of loss of psychic powers. The first witness was Lieutenant Fritzinger, who testified that he had brought pictures of a homicide victim and eight to 10 suspects to plaintiff's office. Plaintiff was able to tell Fritzinger about the victim's lifestyle, age and family. Plaintiff then provided a detailed description of the manner of the victim's death, identified a photograph of the murderer and advised Fritzinger that the murderer had an extensive criminal record and had previously committed a similar crime.

10. Errr. . . what does this have to do with the OP?
Just wondering. Seems pretty random.

11. MRI machines generate high-power magnetic fields
and don't affect people much.

12. But CT scanners are not MRI scanners
The article about the dye is a reaction to a contrast agent for a CT scan, which are basically high-tech X-ray machines. They do not use magnetic fields. The usual problem is with iodinated contrast agents; I understand the usual screen is that people with shellfish allergies are likely to react badly to injection of the iodinated "dyes." There are alternatives but they are more expensive.

MRI scanners work on entirely different physical principles. They do involve short-term exposure to very strong magnetic fields. MRI scans do not involve injection of "contrast agents."

The magnetic fields these folks are using are much stronger than Earth's field, so it's not immediately obvious that our thriving in the presence of a natural magnetic field provides, in itself, any assurance of safety for this technology. And while weaker than the fields in an MRI scanner you're now looking at long-term exposure. I am not worried about power lines and cell phones, but I think it's a pretty bold and probably incorrect assertion to say that the body reacts to electric fields and not magnetic fields. And the notion that their system does not also create electric fields seems highly implausible.

13. You're right.
I was tired when I posted that.

8. Nikola Tesla did this almost a century ago
but the big power corporations stopped him. He was a true genius but the people of that time thought he was a nut and most people today still don't know anything about him.

14. He wanted to do it on a massive scale with free power
for everyone. Can't meter and charge for free power so that was squashed.
