Japan Week Day 1

Just came back after I attended the opening of the Japan week in the University of Jordan.
It was really wonderful, and I was really looking forward to see the SOURANBUSHI ^^ It was really awesome.
I was also surprised by the singing of the "sekai ni hitotsu dake no hana" song, because it's my favorite!! And it reminds me of my first year in the university because it was then when I first heard it.
The martial arts part was cool too^^
In short, I had a nice day. Sorry there are no pictures, I spent the day taking videos of the performances ^^;

...dewa shitsurei shimasu

iya da~~ >_<

why did my ryoushin have to go as far as putting an advertisement in the newspaper?
shika mo, the paper made a particle mistake that changed part of the meaning...
If you have no idea what I'm talking about, don't ask

Make the way for WiTricity

The story is not very new, but very interesting that it deserves a post.
I was always wondering if this idea can be feasibly utilized to totally free us from wires~...
A research team from MIT makes one step forward.
Will we see products in the near future stamped with a WiTricity logo? ^^

The story available in full at MIT news website

Dropping the technical details, it says that an MIT team experimentally demonstrated wireless power transfer, potentially useful for powering laptops, cell phones without cords.

Wireless power transfer over two-meter distance, from the coil on the left to the coil on the right, where it powers a 60W light bulb. Members of the team that performed the experiment are obstructing the direct line of sight between the coils

They were able to wireless-ly light a 60W light bulb from a power source more than two meters away; there was no physical connection between the source and the appliance.
The MIT team refers to its concept as "WiTricity" (as in wireless electricity)

The story summary stops here, the following is a K chan blabla. You might get bored =p

It is said that the idea itself exists since a long time, but nobody tried to do actual work on it because there was no demand for such a system.

When you think about it, for example 10 years ago or older, mobile devices weren't widely used as they are now; so normally the devices were stationary and the power cord we all know would have done just fine.

But now, with the advances in mobile devices, I think it would be very nice if your mobile phone or laptop will recharge it self automatically without needing you to connect the power cord each time the battery goes down.

Or if the technology evolves more, we will no longer have the concept of a BATTERY ^^ ..this will really have its positives.
It's known that the power unit including the battery takes a great part of the size and weight of any mobile device.

If you want to try, remove the battery out of your laptop and see the difference in weight.

If we can get rid of batteries, the design of more compact mobile devices can become easier.
....unless this WiTricity technology would require us to integrate bigger power units!
Another concern that might pop up to the mind is the health impact of such technology.
And I think something else should be investigated. That is the impact of this wireless power transfer on the wireless transfer of data. In other words the interference that it might cause on data channels.

....Ooops....I'm so much into this now aren't I ??
Was I telling people from MIT what they should do?? wake up!wake up!^^;

To tell the truth, I am interested in the wireless technology, and I'm hoping to contribute to it's development some day....That's why I couldn't help but post about this, hope it finds some fans^^;
I just hope that this wont turn into a technical blog! =D
