the machine will "most likely” sport "advanced wireless capabilities, perhaps even wireless charging”.
Thats some seriously big news right there, i thought that it was still in very very early stages (ie they could light a bulb up with it). If it does come to light & becomes available within the next few years surely this is a massive step forward & likely to revolutionise a good chunk of our every day lives?
How come we haven't heard more from Hexus about it? :)

Beat me to posting that, I was also under the impression this kind of tech was a good few years away at least!Quote:

Not expecting it to be quick, but it can't take 6-8 hours for a full charge either.
If you check out the BBC's tech spot you will find a very good section and video posted about 2 months ago from some leading tech company working on wireless power. The technology is complete and well tested. Its predicted mobile phones and laptops would be using this technology between 6 - 18 months and there are some car manufacturers producing electric test cars on the technology. So instead of having to charge a electric car up in your drive way or garage, you can just drive onto a wireless charging area and leave it be.Quote:

I think I read about an Intel technology a few weeks back, re. passively "harvesting" wifi signals from other networks and converting this to energy?
May have a been a daydream though, I dunno :p
40% loss at 6ft with a pair of 2ft diameter coils..
That's the price you pay.
In reality no-one is going to have a huge coil on the moveable device,
so it'll be more like a "charging table", with no plug to bother with.
No matter what you put on the table, it charges...
The possibilities are endless with this technology..
Imagine not even having to bother with new batteries in remotes, childrens toys. Awesome.
I was under the impression there was already a useful (and cheaper) solution?Quote:

In my opinion, this technology is just a useless way of adding more inefficiency to an already lazy society. If the electricity that goes to the wireless charge point is generated at 60-70% efficiency, why then throw away another 40% of that for the sake of not having to walk a couple of metres to the socket and plug in a cable? More wasted R&D money, playing into the hands of dumb punters who won't realise that all their shiny new toy is really going to do is increase their electricity bill, rather than their quality of life.
I would say the exciting thing is a standard for power transfer that every device has a compatable reciver built in for?
I would personally have liked mini-usb or something, but its quite useful in that, and given the frankly shoddy effeciency of some of the transformers out there, a loss of say 20% if its on the desk isn't that bad?
Agreed - hopefully bye bye to all those "wall warts".
I'll bet efficiency is close or better than those on the charging desk idea,
as distance would be minimal.
