"Transatomic"

Leslie and Mark had just gotten their PHD's in nuclear engineering from MIT in 2010.  They figured that they would fix nuclear energy for their next project.  You know what the problems are:  meltdown and radioactive waste scare people.

A 1950's technique using spent fuel seemed promising, so they are working on that under the name Transatomic Power and have attracted some funding despite the wait time.  They won't be able to actually build reactors - assuming they get the technology right - for years, hence investors will have to wait quite a while for a return on their investment.

Bill Gates has invested millions in just this kind of thing with a different company working on the same idea.  With so much of the world wanting to lower carbon emissions, there's potential in clean nuclear energy that doesn't scare people.
