I just want to share a real story, a story that made me believe in my dream of seeing the world run on a sustainable solution. Here, when I say sustainable, I mean the use of Hydrogen as a fuel. Let me begin the story! SUN It's really a very powerful source. What's the sun made up of? Hydrogen and Helium . The Sun is a main-sequence star and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. At its core, the Sun fuses 500 million metric tons of hydrogen each second . The earth on which we are living now was once formed from Sun. Implies Earth is initially made up of Hydrogen and helium, they being the lightest gases they tend to evaporate into space. The remaining elements, carbon, nitrogen, and oxygen are the most abundant. This is due to the fact that the main fusion reaction in large stars is the CNO cycle , which produces these elements as a by-product. These react easily with other elements and produce gases ...
