As we all know most of the power is wasted in transmitting. So we must find a solution so that we can store it in a tank & use it, just like gas cylinder. I am thinking over it. If anybody has the solution please contact.

I wonder when i saw the streetlights glowing in the day also. If the street lights have sensors are adjustable & give light as required. This will save the power. Means by sensing (using LDRs) the requirement of light they will maintain.
