shawn disney Posted 16 days ago Can technology solve our big problems? Why couldn't it? C. Dennis: You might be pleased to know that the energy problem has been solved, on a technical level. An alternative form of nuclear fission engine, invented and demonstrated during the Cold War to power aircraft, is powered by Thorium fission rather than Uranium. It avoids all the scary aspects of Uranium (Fukushima) type plants. The Thorium Liquid Fueled Reactor (LFTR) does not have any fuel rods, water, steam, hydrogen explosions or unmanageable quantities of longlived radioactive waste. In cases of damage, ,or accident it automatically shuts down . freezing any radioactive elements in place, without any intervention, or power requirements to do that. It does not produce usable nuclear bombs, which is why it has not been developed during the last 40 years or so.
