It likely means demolishing a lot of existing houses and businesses to make room for the train

It doesn't. What it means is cutting through a lot of big parcels whose owners have big money, so they can be big impediments. There has to be a happier medium than this between respect for individual private property ownership and the needs of the many, but we are clearly uninterested in finding it in this country.

Submission + - Company "Deep Fission" plans Underground SMRs (ieee.org)

jenningsthecat writes: IEEE Spectrum magazine reports that Deep Fission "hopes reactors in boreholes will be safer and cheaper":

By dropping a nuclear reactor 1.6 kilometers (1 mile) underground, Deep Fission aims to use the weight of a billion tons of rock and water as a natural containment system comparable to concrete domes and cooling towers. With the fission reaction occurring far below the surface, steam can safely circulate in a closed loop to generate power.

In October the startup announced that prospective customers had "signed non-binding letters of intent for 12.5 gigawatts of power involving data center developers, industrial parks, and other (mostly undisclosed) strategic partners, with initial sites under consideration in Kansas, Texas, and Utah". The article continues:

Deep Fission’s small modular reactor (SMR), called Gravity, is designed to stand 9 meters tall while remaining slim enough to fit inside a borehole roughly three-quarters of a meter wide. The company says its modular approach allows multiple 15-megawatt reactors to be clustered on a single site: A block of 10 would total 150 MW, and Deep Fission claims that larger groupings could scale to 1.5 GW.

"We are unique in that we’ve combined three existing mature technologies in a way that nobody had ever thought of before". The company claims that "using geological depth as containment could make nuclear energy cheaper, safer, and deployable in months at a fraction of a conventional plant’s footprint. Still, independent experts say the underground design introduces its own uncertainties, both regulatory and practical."

"why did we continue to feed them?" Did you forget about how the whole industrial Western world runs on oil and that alternatives didn't meaningfully exist until the last decade (and even now they're basically edge cases)?

It would that spoil your little "durr it's all them corporations fault!" oversimplification?

Fair point, so I'll re-phrase my question: "why did we bury our heads in the sand and refuse to hold both corporations and ourselves accountable".

We were still always going to end up with AGW - but we could have been working on mitigation and reduction strategies for at least five decades which we mostly lost, partly to our own heads-in-the-sand behaviour and largely to corporate sand-bagging.

BTW, I still think "durr it's mostly them corporations fault!" We could have had comfortable, happy, modern existences without a lot of the environmentally costly - and unhealthy - excesses which we were seduced and coerced into in the name of obscene profit and corporate hegemony.

The whole point of the label "Dark Energy" is it's a filler for an unknown that still needs to be explained.

The whole point of dark energy is to explain why the cosmos is expanding more than it theoretically should be. If it isn't, then you don't need dark energy, or if it isn't expanding as much as formerly believed then you don't need as much of it.

Uh, even if we wanted to do this why would we contract some random company to do it?

Companies fail, they don't have to be transparent, their leaders are rarely, if ever, responsible for any damage their companies do to people's lives, their primary responsibility is to give value to their shareholders, not do anything good or useful.

Why have we continued to feed all the "random companies" that got us into this mess in the first place? For example, the oil companies knew in the 50's that we would end up where we are now, and created models in the 60's that were still usably accurate into the twenty-teens. They gaslit the world - appropriate pun intended - and they continue to do so. But we still keep buying from them and they are still incredibly rich.

The weaknesses of corporatism are never examined too seriously by the people whose beyond-comfortable lifestyles that corporatism enables.

Having the product stuck on the page makes it appear valuable. (Inflating user counts, familiarizing the public with the brand.)

When the product appears valuable, they can sell more of it (primarily to investors).

They have to give the product away to sell it to a few gullible people.

The fact that there's enough dumb money floating around to make it a worthwhile scam is a whole problem bigger still.
