I find it strange there is no mention about batteries. From what I understand (and it isn't much, I'm way out of my field) getting energy is easy, saving it is hard.

Indeed. The essay mentions "predictability" as a problem with solar, but that becomes moot with good enough storage & transmission.

It's great to see you invest your time and money in nuclear power Sam. We already have the nuclear technology to solve our energy emissions problem, we just lack the political will to make the shift away from coal/oil/gas. Great leaps in the efficiency and safety of nuclear power systems will hopefully make the shift politically achievable.

I worked on renewable energy projects a few years back, and while the idea of a large disruptive technology development sounds awesome, the reality is that there are already a plethora of renewable energy turbines and designs that would greatly improve the world... But the engineers and inventors running around with these ideas have no idea how to go from a small scale proof of concept into a fully built out manufacturing and implementation process.

Even if they do figure out how to get engineering and manufacturing in place, then there are regulatory barriers to figure out. There will be politics involved, and legal challenges. And of course, you need to actually operate the sites on an ongoing basis.

All of these challenges can be overcome... but most people who know how to do so already work in the energy industry. What is really needed is a group of people who can bridge those gaps to take an innovate design from an engineers drawing board, and jump through all the hoops to make it a live production site. If such a group were to be built, real change could happen very quickly.

If you can generate on demand then you don't need batteries.

There is also a very large amount of snake oil in the renewable energy field and a ton of ideas that keep being recycled that have long ago been invalidated.

Precisely! The issue is storage. There are many ways to create energy: solar, wind, water, nuclear (thorium!)...but storage is still unsolved. And Lithium is NOT the answer, not at the scale we need.

Fusion and Fission systems tend to run 24/7, unlike Wind and Solar. There is far less need to store energy when using the former types of generation.

You can either collect and store energy where it's abundant but intermittent (solar, wind), or generate it reasonably close to the consumers.

The problem is that the sources like solar have both power density and availability problems in higher latitudes, and power density required to e.g. power a major factory may be a problem even in a sunny place.

I'm also not sure about price per kW of installed generating power; it looks like solar power is still way behind atomic power in this regard.

In general, everyone would love breakthroughs both in electricity generation, transmission, and accumulation. Looking at the amounts of coal still mined for burning, generation should not be overlooked.
