Wednesday is sci-tech day for this blog site.  But before getting into that, first, a comment about viewership.   Google runs my blog. This is why, in my transition to being replaced by Artificial Intelligence, I turn to Google AI. I have two daily sites with the same posting. The  original one  began 17 years ago and ran out of links to the internet:   This blog site initially focused on renewable energy and the environment. But that was SIMPLE SOLUTIONS for Planet Earth. My next book, SS for Humanity, opened the subject area to everything else, including SETI, the afterlife, travel and cuisine. However, I still provide, now and then, SIMPLE SOLUTIONS. Thus, a few years ago I in parallel started  another blog site  with the same posting of the day:   New SIMPLE SOLUTIONS for PLANET EARTH AND HUMANITY: This blog site derives from the original version of Planet Earth & Humanity, but will be more WE than ME. The coverage will rema...

  Our ship docked in Halong Bay, and I've had a lot of recent coverage because of our  Diamond Princess cruise through this area , so I will today focus on Fusion, the greatest hope for sustainable energy into the long-term future,  Today, only a history. There are two kinds of nuclear reactions. Fission:  splitting a heavy nuclei, like Uranium.  An Atomic Bomb gets energy from fission. Fusion:  joining light nuclei, like, like isotopes of Hydrogen, Deuterium and Tritium.  A Hydrogen Bomb uses fusion. Some  fusion history . In 1920, British physicist Francis Aston discovered that the mass of four hydrogen atoms is greater than the mass of one helium atom, which implied that energy can be released by combing hydrogen atoms to form helium. This concept provided the first hints of how stars produced energy. Henry Russell observed that a star's heat came from a hot core rather than the entire star. Mark Oliphant, working with Ernest Rutherford and oth...
