Could easily be improved upon, seems workable
- defrost 3y agoFor shallow dirt holes, sure. Not so great once the pressure increases or granite|schist layer intercede.
- iancmceachern 3y agoI've been thinking one could add a water powered bit on the tip not unlike the tips they have on more traditional drill rigs. I think there is lots of room for improvement on this technique, lots of white space between this and a traditional rig.
- defrost 3y agoFor the purposes talked about in the linked article they're not really looking for new tech that lies between a traditional mining drill and a garden hose though - they're looking beyond the capabilities of traditional mining drill: Commercial drilling doesn’t usually go much deeper than seven kilometers (four miles)—for cost reasons, it’s often even less than that—and many places that might benefit from geothermal aren’t hot enough at that depth to reach the 150 °C needed to generate electricity economically. Reaching sufficient temperatures may mean going deeper, which would require new techniques and technologies that can withstand high heat and pressure.
- iancmceachern 3y agoYeah, I'm not bounding my thinking, and future plans, by this article. I was just mentioning that something I've been thinking of was similar.
