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)
you can read the whole article here. Now think what are the possibility of this technology available for free and if these chargers are available to the consumers then length of wire we use in our daily purpose will decrease by 40% .What are your thought let me know by commenting down below .
