A comment on Making Nuclear Energy Smaller, Cheaper And Safer.

Complexity is the enemy of any reliable system. No energy source is simpler than solar arrays. They don't require any moving parts, thermal management, waste containment, or strong security. The only maintenance required is dusting. Why otherwise intelligent people cannot appreciate the cost of complexity for nuclear energy is beyond me, especially when viewed in contrast to something as simple as solar.

Except that solar doesn't provide power at night, and reduced power on some days. That means you need either storage or alternative power. Areas which can provide large amounts of solar tend to be located far from population centers. That means long range transmission systems, which are among the most complex systems in existence.

Or you could just overprovision solar.

There are costs other than complexity which must be considered before selecting a power source. For example, energy density per unit area. Nuclear has a much smaller footprint. Also the cost, maintnence, lifetime, and environmental impact of batteries required during night time/occluded operation is also not trivial, as is accommodating for unpredictable outputs due to weather.

Nuclear is slow to operate, so it needs batteries to handle peaks during day. Nuclear can provide baseline power only.

Solar panel can be installed at roofs, so it can double as shelter, and power loss due to transmission can be lowered. Backup gravitational battery can provide backup power on site for short (hours) periods of time, to cheaply offset energy from peak of production at noun to peak of consuming at evening. Efficiency of solar panels can be improved up to 80%, so they can reduce need for air cooling.

Agreed, Also diversity of power is a win. But I agree, with the OP comment here, the simplicity of Solar is hard to get past, but sometimes it just won't work for a given application.
