If there's one thing that REALLY annoys me it's wires! Yeah, it seems silly since we think that we need them. In my mind, even as a kid, I thought there must be a way to transmit electricity with out wires or at least figure out a better way to power our appliances and gadgets. Well, as luck/fate would have it, Marin Soljacic at MIT has finally got the technology at a point where it will be widely available in the next few years!! I first heard about this a couple years ago on MIT's Technology Review website (it's one of my favorite sites! yeah, so what I'm a nerd.) but at the time it was big and impractical. In addition to just making sense and being more convenient, this could have major impact from an environmental perspective. Of course, companies will not stop putting wires on products anytime soon but in the future we will hopefully see a dramatic decrease in the use of PVC & copper for wires. Wires actually account for a major percentage of PVC consumption. There's also the environmental perspective of just how an area looks. whether in your house or on the street, wires are an unsightly eyesore. Think about how much better Tokyo will look without the wires everywhere!
I could go on and on about this but read about it more on his company's website- WiTricity
Just a couple of months ago I posted THESE amazing flat speakers coming out of Taiwan. And now I see these that were actually published even earlier. I think the ones from Taiwan will actually sound better though but still these are amazing!
A groundbreaking new loudspeaker, less than 0.25mm thick, has been developed by University of Warwick engineers, it's flat, flexible, could be hung on a wall like a picture, and its particular method of sound generation could make public announcements in places like passenger terminals clearer, crisper, and easier to hear.
Lightweight and inexpensive to manufacture, the speakers are slim and flexible: they could be concealed inside ceiling tiles or car interiors, or printed with a design and hung on the wall like a picture.
If you're slightly crazy like me, you've thought about the possibility of flat, flexible speakers and if you're even partially out there you've considered paper speakers. Well, our dreams our becoming a reality. Scientists in Taiwan have developed a flexible paper speaker by sandwiching paper and CNTs together.
”Aside from use in family, stereo, or automobile hi-fi equipment, it can also be used in earphones or for industrial antinoise purposes,” says Johnsee Lee, president of Taiwan’s Industrial Technology Research Institute (ITRI), where the technology has been under development since 2006.
The device, named fleXpeaker, is basically a sandwich of paper and metal filled with an electroactive polymer that contracts and expands with an audio signal’s electric field.
”It’s soft [and can] easily fit in different curves,” says Ming-Daw Chen, division director of ITRI’s Electronics and Optoelectronics Research Laboratories. ”Therefore, the product customization can be done in diverse fields, such as art for public facilities, interior design,...costume accessories, and others.”
I doubt these will ever fully replace traditional cone speakers but for many applications these will hopefully become the standard. Read more about it >HERE<
