Public stock exchanges "appear to be warming to climate tech startups," [1]reports TechCrunch . "Or at least some of them."
> This week, nuclear startup X-energy went public, [2]raising $1 billion in an upsized share offering that appears to have delivered a windfall for its investors, [3]including Amazon [and [4]Google. Retail investors apparently can't get enough, with the stock popping 25% in its first hour of trading. Also this week, [5]geothermal startup Fervo said it [6]filed for an initial public offering. The size of the Fervo IPO has yet to be disclosed, but private investors have valued the company at around $3 billion, according to PitchBook.
>
> The move to go public aligns with what investors [7]told TechCrunch at the end of last year. After years of tepid attitudes toward climate tech companies, they expected public markets to start welcoming energy-related startups. Nearly every investor that weighed in on the question said the startups with the best chances of going public specialize in either nuclear fission or enhanced geothermal. Fervo, specifically, was mentioned several times. Thank data centers for that. The AI craze has taken a trend of rising demand for electricity and made it sexy and salable.

It's still not "green" if you just pump it into a datacentre.
In a datacentre, it gets used up by what are effectively space heaters (computers), and then vented out into the world. And about half of that power is used to try to cool that heating by... venting the heating to the world. The actual "AI" output barely even registers in the efficiency of the overall system, even if you use that to design something actually useful (because, yeah, AI can innovate, invent, infer, right?).
There are far more intere

I think of expensive tech that is not viable in the real world for the foreseeable future. Not sure about the geothermal(does it scale outside of special cases?), but I don't include nuclear in this group.
