Too much energy to be harnessed
It is just a small observation or idea about the electromagnetic energy around us. It started from a thought, just a simple thought that how many people can see a pen kr a face or a ball at one time. Take this example. You are sitting in a lecture hall and the teacher writes tbe alphabet ' A ' on tbe blackboard using a chalk. Now if there are 100 students sitting in the hall all if tbem are able to see the alphabet 'A'. Now there are two thi gs to consider 1.

For example leaves appear green due to absorption of blue light by chlorophyll and reflection of other wavelengths. 2. The number if students that see the alphabet is hundred.
