As a physics professor, I believe there is merit to the concern over radio transmission safety. Regarding wireless power - that most certainly ups the ante in a big way. I do NOT believe it will be safe. But... I will wait to review the details.]]>Oct 2nd 2009 3:36AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/

What's so great about sending power over a 50cm gap? Especially tell me what's so great that I want to put up with 40W of power lost (turned into an electromagnetic field and thus heat) per 100W sent?]]>Oct 2nd 2009 2:31AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/Oct 2nd 2009 2:54AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/
"What's so great about sending power over a 50cm gap?"

Um, yea, I think back in 1980 someone said to AT&T: "what's so great about sending telephone signals over the air? who would ever want to walk around and talk on a phone?"

Yup. Now, ask AT&T how much they had to spend in 1993 to get back into that wireless telephone game...]]>Oct 2nd 2009 3:42AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/Oct 2nd 2009 4:01AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/Oct 2nd 2009 4:15AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/Oct 2nd 2009 10:21AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/
if you want technology to change the laws of physics you need to get out of your la-la land. We need to find out ways to produce more power with less resources, then we can let power "go to waste" and use wireless power. Untill then...50cms of wireless power is useless, ill stick with power cords. ]]>Oct 2nd 2009 2:02PMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/Oct 2nd 2009 2:43AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/Oct 2nd 2009 3:19AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/Oct 2nd 2009 10:43AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/Oct 2nd 2009 2:53AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/
If that chance is anything higher then 0% this thing scares me. Even if I would have to put my body directly in between the two objects.

Yikes.

Seriously, anyone putting a wireless big-screen TV in their house should be electrocuted. Wireless power transmission is great for convenience's sake with portables, but we don't need to be systematically decreasing our efficiency by using it for installed appliances...

It will be awesome to see people with this tech in their house in the near future complaining about the supposed detrimental effects of cell phone radiation, though. ]]>Oct 2nd 2009 3:42AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/2. Imagine if you can put all your portable devices on top of a table and get them all charging, or roll your car into your garage and charge it without plugging any wires.
3. Don't be anal, a few feet is a good start.]]>Oct 2nd 2009 3:46AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/
It isn't a few feet, it's under two feet. And you're making a really stupid assumption that it will end up going much farther than a few feet. It just doesn't work that way. Look up induction.

I don't care about contactless charging. It's not so difficult to plug a cord into my phone or my car that I can't be bothered to do it.

If you think that just because the earth's magnetic field doesn't cause harm that you can see that no magnetic fields can, then I encourage you to go check out an MRI machine sometime. Take a look at the safety measures around those and tell me that no magnetic field can be a problem.]]>Oct 2nd 2009 4:06AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/Oct 2nd 2009 3:56AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/
Aside from that, 50cm is just a start. The first cars went 15mph I believe, but with improvements we have (specially designed) cars that can hit 300mph. Wireless internet used to be pretty bad with weak signals that were easily interruptable, but has since changed to be quite reliable. Yes, 60% efficiency is garbage and I don't think a lot of consumers would even accept that (if they were informed), but again that's where research comes in. As Giordano points out, there are lots of applications for wireless power, you just have to be creative.

@ the physics professor, I believe the previous comment was in regards to these waves causing cancer. Yes a microwave can kill you, but only because it causes the water in your body to boil. I don't think I've seen any proof that microwave or any other sub-UV waves causing cancer.]]>Oct 2nd 2009 4:24AMhttp://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/http://www.engadget.com/2009/10/02/sony-dives-into-wireless-power-game-makes-it-way-more-interesti/I hope you know that current internal combustion piston engine sitting in your car in your driving is less than 30% efficient. It only produces meaningful work 25% of the time it is running and the rest is waste heat and noise. The only engine that is currently the most efficient is the Tesla Turbine. it is 98% efficient.

And for you all who are worried about harmful effects, I regret having to tell you this, but any electricity moving through wires generates radiation, so it's all over you all the time. That's why your blender causes static on the TV. My recommendation is that you wrap yourself in aluminum foil and keep your head in a metallic mesh bag.
