Book excerpt: This is a story of space, time, matter, energy and energy conversion. Written by Joseph Y. Hui, aka Solar Man, this book survey the nature of energy, its expansion in spacetime since the Big Bang, its condensation as matter, and its exertion as different kinds of forces, and its manifestation as different kinds of energies. The bulk of the book is about energy conversion and its impact on the environment. There are five major sources of energy conversion into each other: motion, electromagnetic,light, chemical and heat. We introduce each topic on 2 page layout of scientists. They may have discovered and explained the physical phenomenon. They may have created the invention of energy collection, storage, conversion and use. Many of the inventions are due to Solar Man in his quest to solve the three E problems: Energy, Environment, and Education. His inventions involve water, energy, food, information, and transportation with acronym we-fit. The book is also written as a prototype for Solar Wonderland, a science amusement park for educating on the 3E's. Solar Man's motto is "Live a comfortable but sustainable life". Solar Man also plan to commercialize his inventions by Monarch Power, his R&D company.
