Image based traffic Signalling

May be a junk concept:

Also not that feasible to implement.

Take a photo of the Road in front of you

Search for the empty area in the photo

If the top portion of the Photo is not heavily populated( still has the color of road), it means that the road is not heavy on traffic.

Based on this decide when to sitch on/off a signal

Mobile Auto Charge

I had thought of this concept when I saw a blinking panel attached to most of the mobile ( for showoff) a few years back.

I was amazed about how the light blinked without power. Then when I learnt telecom I know it was Power transmitted from BTS.

When we can light up an LED then why not charge the mobile?

A power wave is continusoly broadcated to our mobile frequently frm the BTS to locate our Mobile/Keep track of it. The Power radiation can be then amplified and used to fuel the mobile.

We can make the backcover of the mobile as a reciever of such signal and charge the mobile.
