wireless energy transfer

What if we can transfer Energy through Air ?

Now a days the only energy that we consider is the battery life of our smartphones . However there is one energy that can be transferred through air and even vacuum ie: Light . Today i came up with this thought that How can we transfer Energy from one place to another through air ? . What if we succeed and what are the things that we can do ?

Until today our technology has become so advanced that we are able to electromagnetically charge our phones just by keeping our phone on the top of the charge pad . Now we can just touch our phones and transfer messages via NFC (Near Field Communication) . Now what if we can charge our phones on the go ? .

Lets say that the charger is a some kind of a Wi-Fi module that sends a probe request to your smartphone after certain period. If the Phone is at 45% battery life then the phone will accept the probe request to say that its around 45% charge and sends the reply . That Charger should send the Energy modules to the phone so that it can charge it self.

Another idea is that we should create a phone whose screen is a kind of solar cell and also transparent for display . Now when your Phone sends the same reply to your Wi-Fi Charger it will send your phone the amount of Solar Packets it needs to fully charge it self . On receiving the solar packets, the phone should activate its solar cells at this time the phone will act as a solar panel to charge its battery.

Update : Japanese scientists have succeeded in transmitting energy wirelessly, in a key step that could one day make solar power generation in space a possibility.- Japan Aerospace Exploration Agency (JAXA)
