The next video is a presentation & discussion of thorium, an alternative cleaner way to produce energy. It's interesting to watch.
Thorium is readily available & can be turned into energy without generating transuranic wastes. Thorium's capacity as nuclear fuel was discovered during WW II, but ignored because it was unsuitable for making bombs. A liquid-fluoride thorium reac tor (LFTR) is the optimal approach for harvesting energy from Thorium, and has the potential to solve today's energy/climate crisis. This 16 minute video is summarizes 197 minutes worth of Google Tech Talks on the subject of Thorium & LFTR.
