Solar energy now overlaps in cost with nuclear fuel alone for "cheap" modular reactors (energy-utilities.com)

Uranium is $128.30/kg

After enrichment, conversion and fabrication that's $3400/kg for 4.95% fuel.

At 36-45MWd/kg and a net thermal efficiency of 25% or $12.5/MWh up front.

With a 90 month lead time (72 month fuel cycle and 18 months inventory) at 3% this is $16.2/MWh

Which some solar projects are now matching

There has been some cool innovation in renewable energy storage such as pairing it with hydro and pumping water back up using access electricity during peak production.

I love these fiction land scenarios that magically change the landscape.

Woah there I'm just saying it's cool not that I think it'll save the world or anything.

The innovation is there but it's not viable yet for a country, or even city wide grid. Hydro is okay but severely limited by geography, rocks up a mountain could work too but it's also limited by geography to some extent.
