A look back on popular stories from today in a specific year.
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
Tesla was Serbian.
If u read more carefully u'll see that i wasn't trying to take away hes Serbian heritage by my statement.
Is this thing safe??
that's what she said.
How do you turn the thing off? I mean if it's embedded in a table or countertop, It seems like the primary coil would have to always be on so it will be ready to provide power to the secondary contained in any device that might need power/recharging. Seems like even if they achieve a high efficiency of electrical transfer, the primary coil will be on all the time, whether a device is in its proximity to be recharged or not. I thought we were all supposed to be conserving electricity...
Whoop tee do, you created an air core transformer. Anyone who owns a Wacom tablet can open it up and see the same coils inside the mouse/pen. How do you think they make them batteryless. Great demonstration of 100 year old technology.
Budweiser needs to beam beer directly into my stomach from 10 feet away. Wtf happens if you walk in between that thing? lulz don't taze me bro.
This really is nothing new.
If any of you were curious the recharging system that Oral B powered toothbrushes use this technology. I know this because i completely disassembled one that quit working months back.
Hang on a moment - this doesn't sound like what Tesla was doing, and I don't really understand why people think it is the same thing. Did Tesla use resonant induction like this device appears to? Also, it doesn't sound like the technology used to charge toothbrushes, which, as others have said, is very conventional induction technology.
I think that 60 watt power transmission for 3 feet with only 25% power loss is pretty impressive. When MIT demonstrated their prototype device, which was similar to this one, in 2007, the energy loss was much greater, as far as I recall.
So...I don't want to wrap my Jack Russell in aluminum foil and teach him to jump through the hoops?
I'm sure wireless power is totally harmless, nothing to worry about! http://notnews.today.com/2008/08/23/intel-demonstrates-wireless-power-for-the-home/
Intel CTO Justin R. Rattner: Wireless Energy Resonant Link- one step closer to Star Trek!

This new innovation has nothing to do with Tesla's inventions. Tesla was using different principles, and while his experiments were interesting, there was no way it would have been efficient enough to use widely. And no, he wasn't killed by "Them" for knowing too much. That's some more of that conspiracy theorist BS you have to watch out for. You know, like the morons who think no one landed on the Moon, the people who still can't believe that crazy Muslims caused the September 11th attacks, and people who believe in Santa and Jesus.
Anyway, interesting stuff, although one hopes they can shrink down that massive 1950's spaceman antenna for the production models.
I think it is great to see the Intel announcement and the MIT work being promoted. In reading the blogs, and the engadget comment, there was one statement I would like to single out ... a number of wireless systems come and go. Lux Researach reports over 153 companies in alternative power and energy storage, with over $1.7 BB in venture capital. Although Intel, MIT is promoting inductive powering, there are many approaches to wireless power. Powercast is RF power. Wildcharge employs micro-contacts. There are kinetic based technologies such as Piezo, flywheel, vibration and so on. Of course, there is solar, wind and hydro-motion.
Furthermore, beyond the convenience issue of now wires, there are very good reasons to continue taking this seriously. There is advantages such as the opportunity to hermetically seal a power supply (Industrial & Defense), there are configurations that provide freedom from spark and arc (Mine Safety), there is an opportunity to simply augment fossil fuel powering (Green), and so on. In other words, rather than throwing the baby out with the bath water, all of these power technologies should be considered in situations that fit them ... not as a universal exlixar.
Just a thought. Steve
