Shane and Rod provide a different take on a current debate regarding the use of enriched uranium. There is a notion among a certain kind of politically educated person that the only valid use of enriched uranium is to produce weapons that can be used to assure mutual destruction. Rod and Shane explain that enriched uranium is merely uranium where a major portion of the U-238 had been removed leaving U-235, which is the isotope that fissions most easily.
This process not only enables the production of bombs by a team of people with sufficient engineering and mechanical skills, but it also enables the construction of very small and safe research reactors and small power reactors. These small reactors without a lot of neutron absorbing U-238 can be used for experiments, education, and power production in remote areas. In other words, they are something that is quite useful for a countries that have massive commercial nuclear power plants and for countries that do not need massive commercial power plants but want to learn more about nuclear technology or have distributed power needs that can best be served by small power plants.
Shane and Rod then shift gears completely to a discussion of energy efficiency and talk a little about Amory Lovins, who has been one of the gurus of the energy efficiency community for the past 30 years. Listen carefully, you might learn a little known tidbit about Mr. Lovins early academic career.
