Bill Gates investing more on nuclear energy

Whether this idea will work or not, it is great that someone is willing to put the money required to do the research required for it! without such investments and research no progress could be made: "The outside of the travelling-wave reactor will be similar to today's reactors, but the inside is radically different. A conventional nuclear reactor depends on enriched uranium to generate its heat and electricity, but the travelling-wave reactor uses only a small amount of highly enriched uranium (U-235) to kickstart fission and a slow-moving chain-wave reaction. Two parallel waves of fission then move about a centimetre a year, splitting uranium atoms of the spent nuclear fuel (reprocessed uranium) or unenriched uranium (depleted uranium, U-238) packed into the core, in a process that first creates plutonium-239 and then consumes it. This reaction should be much more efficient than a conventional reactor and, in theory, can be sustained for decades."
