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 reactor (LFTR) is the optimal approach for harvesting energy from Thorium, and has the potential to solve today's energy/climate crisis.
The end of the 1st 5 mins is clearly marked. I asked Gordon for permission to submit his 2011 Thorium remix (filmed and edited himself) to documentary sites.
