People tends to love counting down for new year.

A brand new starting point, gives everyone hope.

Whilst hope, is what drives us daily for a better tomorrow.

Instead of becoming a big dreamer, it’s time for some actions.

It seems that it’s going to be a busy year for me,

Didn’t realise earlier I’ve actually got not many weeks left for my FYP,

after deducting time needed for other assignments and holidays.

but being busy has much more fun than doing nothing.

life’s so fucking short. do whatever you want today.

quoted from last year,

If you’re not going to do it today, you’re probably not going to do it tomorrow too.

Happy new year, everyone :)

p/s does my language or my blog’s snowy greyish make you all feel im emoing? nope im not, not at all.

This year, to save me from tears, I’m giving it to myself :)

What’s wireless energy transfer?

It means transfering energy without wires. duh

Nikola Tesla came out with this idea, 100 years ago, in his Wardenclyffe Tower project.

The inductive charging technique

Induction charging products are widely available such as

the ‘wireless’ charging toothbrush

and the phones charging pad.

It’s sort of wireless but it is still very near field charging technology.
MIT decided to say it’s not enough

Resonant Inductive Charging

The MIT team came out with a research group, the WiTricity and successfully achieved a distance of 2 metres with 40% power transmission efficiency. This makes the possibility to  wireless charge every single electronics in a home/office comes to a reality.

How?

with Resonant.

It’s an efficient energy exchange between tuned resonant objects at certain frequency.

In the project, there are two coils, a transmitter and a receiver.

The current passes thru the transmitter coil will induce a magnetic field.

With this technique, wirelessly powered devices are made possible. Say byebye to Lithium battery.
