23 months to build is impressive, but the number that matters for EGS is thermal drawdown. If the fractured rock cools faster than modeled they have to keep drilling new wells, so I'd like to see Cape's output a few years in.
Op is really just describing a core breakeven metric on the energy source. In the same way you measure an oil well with half-life of useful output, this is basically saying "EGS can prove to be useful if they can make sure they extract more economically useful heat than the economic costs of constantly drilling new wells."
Since no one has really made EGS widespread yet, that suggests no one has yet cracked this nut.
That seems like a fallacy.
"If the internet was useful, everyone would use it" is something that wouldn't stand the test of time, right?
And at the time I write this, it breaks the world record for HN comments by the world’s first brudgers.
The internet expanded as the result of semi-conductor break throughs made by thousands of engineers with access to semi-conductor break throughs. There was a ‘virtuous’ cycle.
That is not the same thing as a press release. ‘World’s first,’ ‘New Record,’ and ‘Scientists’ correlate with press releases. Press releases make for easy news content and news sites are attracted to them.
It is premised on a belief that a significant number of smart motivated professionals have been trying to solve the same problem with substantially the same budgets and technologies for many years and that experience has led them to an informed belief that more practical solutions exist.
You might say it is a stronger belief in engineering practice and economic efficiency than in press releases.
[note: I agree it would not be “everywhere” because the practicality of drilling into bedrock varies significantly between locations. But that is not a point in favor of scaling the proposed technique]
