It's a very clever idea and a really cool proposal. The paper's abstract does a great job summarizing it: "The USA is confronted with three epic-size problems: (1) the need for production of energy on a scale that meets the current and future needs of the nation, (2) the need to confront the climate crisis head-on by only producing renewable, green energy, that is 100% emission-free, and (3) the need to forever forestall the eruption of the Yellowstone Supervolcano. This paper offers both a provable practical, novel solution, and a thought experiment, to simultaneously solve all of the above stated problems. Through a new copper-based engineering approach on an unprecedented scale, this paper proposes a safe means to draw up the mighty energy reserve of the Yellowstone Supervolcano from within the Earth, to superheat steam for spinning turbines at sufficient speed and on a sufficient scale, in order to power the entire USA. The proposed, single, multi-redundant facility utilizes the star topology in a grid array pattern to accomplish this. Over time, bleed-off of sufficient energy could potentially forestall this Supervolcano from ever erupting again. With obvious importance to our planet and the research community alike, COMSOL simulation demonstrates and proves the solution proposed herein, to bring vast amounts of green, emission-free energy to the planet’s surface for utilization. Well over 11 Quadrillion Watt hours of electrical energy generated over the course of one full year, to meet the current and future needs of the USA is shown to be practical. Going beyond other current and past research efforts, this methodology offers tremendous benefits, potentially on a planetary scale." The obvious questions have to do with political feasibility and cost. Is this realistically possible? Is there enough citizen, business, and government support to move forward with it? Do we have the resources to pull it off? Can we afford it? Deep inside the paper I found this tidbit, suggesting the authors don't know: "There is no question that this entire project, including facility construction, as well as the upgrade for the power distribution network, would cost trillions of dollars. This paper was not, however, written to discuss the wisdom of such a costly investment. Even if spending these many trillions of dollars is not practical, it does not mean that any of the proposed ideas is not doable and should not be contemplated. This paper was thus written with the intent to propose these ideas and analysis within the realm of a thought experiment. The ideas presented here are entirely implementable with enough national will, and a large enough pocket book to do so."
