Geologists Prepare to Drill Into Ancient Antarctic Lake | Rc Dth Hammer

Officials said a purpose-built cage was used on Thursday to take the miners down the shaft that was been drilled parallel to the borehole.

Woskov laughs when he reveals that drilling engineers have a hard time believing his technology does not use the costly drilling mud they depend on. But, he explains, with a gyrotron, high-temperature physics will replace the mechanical functions of low-temperature mud, allowing drillers to extract rock matter through vaporization or displace the melt through pressurization. Similarly, the high temperature melted rock will seal the walls of the borehole, and the high pressure from the increased temperature will prevent collapse. In principle, because an increase in temperature in a confined volume will always result in an increase in pressure over local pressure, drillers could maintain the stability of a borehole to greater depths than possible with drilling muds.

- Sustaining capital decreased from $0.3 million to $0.07 million as the heap leach operation winds down.

- Mineralization was confirmed at-depth in the North Pit. However, in the short-term no follow-up drilling is planned for this target as the potential resource in this area may not be suitable for open pit operations. As such, the focus remains on testing other open pit targets.

Pacala equates the challenges confronting Climeworks and Carbon Engineering to what the wind- and solar-power industries faced in the 1970s and ’80s, when their products were expensive compared with fossil fuels. Those industries couldn’t rely on demand from the private sector alone. But some policymakers perceived tremendous environmental and public benefits if they could surmount that hurdle. Government investments in research, along with state and federal tax credits, helped the young industries expand. “Wind and solar are now the cheapest forms of energy in the right locations,” Pacala says. “The return on those investments, if you calculated it, would blow the doors off anything in your portfolio. It’s like investing in early Apple. So it’s a spectacular story of success. And direct air capture is precisely the same kind of problem, in which the only barrier is that it’s too costly.”

Finally, even if the world is cajoled into using water more sustainably, that will still leave questions of allocation. On the global level, it is easy to see where the priorities should lie: in the hundreds of millions who do not yet have access to safe and adequate drinking water and sanitation. At the national and subnational level, there will always be powerful interests lobbying for their own needs, whereas those without access to clean water are, almost by definition, the powerless. So, as Jonathan Farr, senior policy analyst at WaterAid, puts it, water management—however sustainable, progressive and integrated—has first to concentrate on access. Money is not the binding constraint. Nor is technology. It is a political choice.
