Nah, this isn't a temp gradient - remember that the mud is colloids in a water\/ steam suspension. The steam is acting as a crude \"ejector\". Because of depth there is a linear pressure gradient. Drill down 150M and the water in the mud will sit quite happily at 180+C without boiling, but give a vent to this mud, and in the first instance as it rises out of the drill hole there will be a huge release of steam and mud which will then slow down and stabilize as a pressure gradient is established. Dependant on local conditions the mud may be sitting underground at 60C (in the case of Scotland, probably bloody frozen) or in a superheated condition at 600C which is fine until someone take the plug out of the hole then it will desuperheat kicking out huge amounts of energy.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/us-firm-mulls-building-geothermal-power-plant-from-sidoarjo-mudflow-1215657299", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
