Witricity is based upon coupled resonant objects to transfer energy between objects without wires. The system consists of a Witricity transmitter, and devices which act as receivers.
Like radio receivers, the devices must be in range of the transmitter. Unlike the conduction-based systems built by Nikola Tesla in the late 19th century, Witricity uses resonant magnetic fields to reduce wastage of power. Currently the project is looking for power transmissions in the range of 100 watts.
As they put it: "Using self-resonant coils in a strongly coupled regime, we experimentally demonstrate efficient non-radiative power transfer over distances of up to eight times the radius of the coils. We demonstrate the ability to transfer 60W with approximately 40% efficiency over distances in excess of two meters. We present a quantitative model describing the power transfer which matches the experimental results to within 5%. We discuss practical applicability and suggest directions for further studies."

i going to start my associate degree this upcoming fall. just wondering what to go for. I definitely want to do something with computers. the local college offer these 2 programs that i am interested in but not sure what i would be doing once i get out and how much it starts or pay. please answer. below is the list of classes im going to have to take for each program. so please answer their salaries and what can i do with each degree. thanks ahead.

After many times of testing, I realised it was the PCI Wireless Card Adapter. However, I brought the computer home to use, the auto shut down problem did not happen at all ( everything was the same, no removal of any hardware). Can it be the office electricity current be the cause of the problem? The computer never had such problem in the past, the auto shut down problem only started last week.
The info on my box is:

Hi
I am looking for a skype phone which would work with home internet connection without electric power like ordinary home phones which works even if there is no electricity in house
skype mobiles need wifi connection which need a router which required electricity so it is not an option.
Netgear or edge skype phones are also on wifi so it is not an option either
What I am looking for is a skype phone which would connect directly to the internet wire(ADSL connection).
I think adsl modem is an essntial thing but i am looking for a solution and not really good at these things .

and if you have, do you know when it will be available to the masses?
i'm curious because 1. it seems like a really cool invention. and 2. i am sooo tired of having all these wires around my room. it sucks. Witricity powered: witric power.
Hi guys! I'm currently taking up Information Technology and we are required to pass a thesis proposal. We have already passed a lots of thesis proposals but all of it was rejected (some are not completely rejected though) either because it's not feasible or it's already existing or it's too easy.
The requirements for our thesis are:
1. It must be realistic and feasible.
2. If it's already existing, find a way to enhance it.
3. It must consist of a hardware and a software. It must make use of an embedded system.
4. It must not cost too much.
5. It must follow the code of ethics.
