The cheapest energy will come from a simple mass-produced reactor rather than the best design -- nuclear's problem is the Toyota Camry problem.

design How things should be made and judged: what makes a design good, who should do the designing, and what an interface is for.

simplicity Less, but better: reduction as the way to make something good, and the argument about when it goes too far.

nuclear power Fission as an energy source: what it costs, what it risks, and whether anything else can do the job.
