Snowstorm shuts down expensive nearly useless solar plant in Massachusetts.

14. Basement actually, but you are conceptually correct.

Small, sealed canister nukes that run maintenance free for 10-20 years at a time.

Nukes that incinerate their own ashes in situ. (And can be easily configured to burn the ashes of previous generations as well.)

Nukes that go from hot to cold at the flick of a switch, AND that is also the ONLY possible failure mode.

Nukes which can safely be run at temperatures so insanely high that hydrogen and oxygen are literally waste products.

Nukes which must be externally energised to burn their fuel one discrete and very subcritical gram at a time.
