How can they talk about lunar power without mentioning nuclear? It's dark for 14 days!
> The area with the highest incidence of sunlight was 89% at the north pole, followed by 86% at the south pole, equating to 324 and 314 days of sunlight a year, respectively. There were also many areas around crater rims where the yearly percentage of sunlight was at least 80%. The existence of polar areas believed to be in permanent shadow was confirmed by the survey.
They'll be fine with some batteries, and the poles are already prime spots due to permanently shadowed craters holding ice.
(Or, put solar panels on various redundant high points; different bits of the poles get their 80% at different times. Run cables to the base.)
Even using a simple Stirling enginelike in NASA's Kilopower [0] project isn't super challenging expensive compared to battery solutions or power relays (e.g. from the lunar south pole or satellites).
I see no reason why nuclear power wouldn't be a viable and very competitive (or even essential) part of lunar exploration.
