Myself Posted February 26, 2008 Report Share Posted February 26, 2008 I was absolutely amazed when I first heard about this. http://cosmos.bcst.yahoo.com/up/player/popup/?cl=6653023 Of course one of the technological hurdles they said they'd have to overcome is transmitting power wirelessly. Is that even feasible? Quote Link to comment Share on other sites More sharing options...
DragonMaci Posted February 26, 2008 Report Share Posted February 26, 2008 Of course one of the technological hurdles they said they'd have to overcome is transmitting power wirelessly. Is that even feasible? Yes, it is. Wireless charging of portable devices like cellphones and laptops is due this year or next. Quote Link to comment Share on other sites More sharing options...
UptonStellington Posted February 27, 2008 Report Share Posted February 27, 2008 That's amazing! .... DragonMaci, where did you find out that wireless charging is due out soon? Quote Link to comment Share on other sites More sharing options...
softwareNerd Posted February 27, 2008 Report Share Posted February 27, 2008 Wireless charge "pads" are out already. As far as I know, the device being charged has to be compatible. Quote Link to comment Share on other sites More sharing options...
Myself Posted February 27, 2008 Author Report Share Posted February 27, 2008 Hmm... From what I can tell the wireless charging available now still requires the device to come in contact with a "charging plate." I think "bionic vision" contact lenses would need to be able to receive power wirelessly without having to physically touch a charger. The question I was asking was: is it physically possible to "beam" power through the air? Quote Link to comment Share on other sites More sharing options...
D'kian Posted February 27, 2008 Report Share Posted February 27, 2008 Hmm...

I think "bionic vision" contact lenses would need to be able to receive power wirelessly without having to physically touch a charger. It depends on their power consumption. If they were good for, say, 12 hours, you could remove them at night for charging. The question I was asking was: is it physically possible to "beam" power through the air? Yes, but until recently it wasn't economical. Over large areas, say you wnated to power a city or a small town wirelessly, it still wouldn't be economical. there are products in development that merely have to be near a power source in order to get charged, say 3 feet. There ahve beena rticles about it in science periodicals over the past year or year and a half. try looking up the Scientific American website and see if it lets you search through past issues.

I didn't realize those pads used physical contatcs, I thought the device had to be "close by". The question I was asking was: is it physically possible to "beam" power through the air? Here's an article about some MIT guys transimitting power across 7 feet. Still experimental. Quote Link to comment Share on other sites More sharing options...
pathannarris Posted November 1, 2008 Report Share Posted November 1, 2008 This idea is actually similar to what Nicolai Tesla did back in the later part of the 19th century. Tesla was an electrical engineer/inventor who worked for Thomas Edison for a time until Edison renegged on their earlier salary agreement. If you have ever watched the movie "The Prestige", you see the main character of the movie working with Tesla on top of a mountain range in Colorado. Tesla advocate the use of a high-powered ultraviolet beam to power objects without the wires. Tesla was also one of the first to notice the effects of X-rays.
