Considering how many fussy people there are, its potential is great.

The Drilling Fluid control would be just nuts.

I just looked into some borehole energetics. A high estimate is forty to eighty watts per meter of depth. So to feed a typical 4-gigawatt carbon-fired power station would take between five and ten thousand boreholes exceeding 10 km in depth.
I also remember a shallower hole requiring half a million dollars worth of electricity for the drilling operation, minus ancillaries like dross management and extraction hardware. That’s as much as five billion dollars (pre-pandemic and prewar) to power the drilling. Wonder if they’ll recoup that before chilling the target volume below breakeven heat flow.

In the video the guy behind it estimates an 8" dia hole 10km deep would cost about $500K in electricity (8:00 min), so say to get to 15km would be around a million in power alone with a gyrotron. An 8" borehole producing supercritical water will drive a lot of turbine megawatts, even with the inefficiencies of an intervening heat exchanger.

Iceland uses a lot of geothermal. It is right next to the surface there, so no need to drill very deep.

Low flow is letting salt water back into fresh water marshes, etc. etc. It's bad.

Solid State Batteries are on their way folks! And they have been for more than a decade!! No-one's quite nailed it yet, at least not for mass produced EVs, or aviation. But that could all be changing if NASA's latest breakthrough is to be believed. So is it just more hype, or is there some real hope this time?

Not that much is known about it, he is just reporting on a news release I posted earlier. What is available is on the NASA website, it could make a contribution to other chemistries too, my fav would be Sold state Lithium Sulphur, if possible. There is so much work being done on novel battery chemistries and putting theory into practice on a massive scale. All the car companies are betting the farm on EVs and there must be better prospects for batteries afoot, he quickly ran through a few ones nearing or in production.

that's what you get when you have a caste system that considers those further down the ladder no better than animals...
they need social reform in step with much more stringent environmental laws.

i may have presented that wrong...that is two separate, unconnected statements for the most part...one does not flow from the other, although, imo, one is a requirement for the other matter...
why would they bother to clean up the pens of animals they don't really give a shit about? only because of the causal effect it has on them.
given what i have seen of Indian society (admittedly limited)and the importance of "place" in that society, i can't make myself believe those in charge of India give one little shit about those of a significantly lower social caste.
