MATH’S NOTES

While surfing the internet, as I do from time to time, I came across several articles relating to energy harvesting. For those of you who are not familiar with this topic, simply stated, it is obtaining electrical energy from situations where it is not normally present. Since physics tells us that energy can always be converted from one form to another, it seems that this is a great area for experimentation and I would like to relate some of my thoughts in that area.
