Wireless Charging Advancing

What's a phartsmone?

an overpriced toy we demand as a minimum here in the civilized world..sad but true

Sad indeed.

I know we all want to believe that low level electromagnetic radiation is inert.

I've not seen any actual research that can prove this to be true (or false).

Quote from the link "(The power level of the beacon signal is too small to cause any biological damage, even with long exposures.)"

We'll see how that experiment goes.

We've also been told that eating at MacDonald's we will ingest, "delicious and nutritious food". I think I'll stick to the wireless charging for now.

You have a choice to eat at MickyD's, you don't have a choice about ALL the EM radiation.

There certainly is evidence that it's an issue. But like most cancers, the immune system kills them, or not.

My past job was testing avionics, and HIRF (High Intensity Radiated Fields) was a big issue in the test lab to not get burned or irradiated, as blood cancers were a known possibility (under extremely high field strength). We know there are issues with 60Hz high tension lines, litigation has resulted in big payouts.

For avionics you have to show a catastrophic failure rate of less then 1 per billion hours of operation. That will be impossible to prove with RF fields, without lots of human exposure time. And even then, prove root cause.

It's one thing to transmit low level communication RF (micro-volts/meter), but wireless recharging power is a totally different field strength.

We will see if this inventor can get regulatory approval. To me it's not a big issue to plug in the phone, but then it's not my only access to the world.

This technology has it's uses. I think they go little to far in their list of uses. With the ever increasing cost of energy. There is too much wasted in charging items like this.

consider the risk to reward ratio:

risks: TBD, possible brain cancer or leukemia or ??? simply unknown

rewards: this device has a range of 30' maximum. so the rewards are:

1. not having to walk 30' to plug in, and

2. being able to use your phone 24/7 without remembering to ever plug in

is those rewards worth that risk?

The benefits are countless. This system can be incorporated in your car, home, office, restaurant, gym, grocery store, McD's, Dunkin Donuts, Starbucks, movie theater, car dealership (yes, you're going to be there for hours), car repair shop, DMV, shopping mall, bar, Barnes and Noble, Apple store, post office, etc.

How many times has your iPhone ran out of power and you had to find a place to plug in? Now you can have dinner, go see a movie, mail a package at the post office (you'll be in line long enough to get a good charge), go to the DMV, or get a Big Mac Super Size meal, then go the gym to burn it off!

Yes, but once people start to charge their millions of devices at all those thousands of places, how is the energy going to be billed? They won't be giving away all those (cumulative) megawatts for free. Sounds like there are some big issues on that end to be worked out before it gets off the ground.

I think it'll be another perk for shopping at that place. Just like free wi-fi right now. Maybe a trade off for higher foot traffic or they'll need to raise prices.

I see the problem as something different. We've grown dependent on our smart phones, which isn't a bad thing, except when we're killing the batteries playing Candy Crush or doing Facebook - social things; well that's using natural resources for something that has nearly zero value to society.

Interesting application of phase conjugation. Don't know if it's safe or practical.

Yeah, I hear that giant sucking sound again.......

.....Of us being left behind.

In your link article a quote "The researchers say the electromagnetic fields involved do not pose a health risk".

Again, let's just tell people there's no risk, as if there is, you can't prove it.

Chicken little's abound. But being engineers, I know none of us would ever believe something that has no imperical evidence in support right?

I think we have all heard the stories. Troopers sterilizing themselves with radar guns. People getting brain cancer from cell phones. Microwaves causing miscarriages. etc. I would hope we are all sceptical enough to realize none of that has ever been proven as real or a medically verified as a real risk.

My point is this, we are letting other countries move well past us technologically as we continue to suckle at big oil's tit and using old wives tails as the excuse to fail.

Come on America, we used to be better than that!

Unless, of course, we are ready to lie down and accept Putin's assessment of America.

I think that microwave radiation does have an effect on cells - it is energy, right. Just like the sun affects cells - energy also.

For the majority of people, our immune system is able to combat the effects of the sun, so most of us don't get skin cancer. But what about the people who do? Why does their body fail to protect itself against the cell damage from the sun, yet others don't?

I believe the same is true with microwave radiation. I read an article where they tested mice with a gene that made them susceptible to lymphoma vs regular mice. Both were given non-ionizing levels of microwave radiation - I believe three times a day. The mice with the lymphoma gene did get cancer at a substantially higher rate than the regular mice. They duplicated the test with the same result, so from a scientific viewpoint, there is a link between non-ionizing microwave radiation and cancer in mice.

From a conservative standpoint, we should minimize our exposure to strong microwave radiation. Since power falls off at the square of the distance, keeping away from the source is a good idea. Also, keeping away from high power sources makes sense. If you have no trace of lymphoma cancer in your family, then you don't need to be as concerned. If you do, however, you should take as many precautions as you can. It's like the person who has skin cancer in their family tree. It's prudent to protect yourself as much as possible against the rays of the sun. Even if you aren't getting sun burned, you can still get skin cancer from the uV rays. Correct me if I'm wrong, but I don't think it needs to be ionizing uV to get skin cancer.
