Many thanks for your dedication and commitment. As soon as the boiler will be repaired, the value of your surveillance will become even more obvious! The possibility of a quick restart of the drilling activities depends on your dedication, so good job indeed!
Most relieved to hear you have a way to keep all that water in a fluid state while the boiler is down. A real belt n braces approach, well done.
Looking at Chris’ video on the BBC and his sketch, very helpful, I landed up w two more questions.
Have you drilled the second hole down to the caravan reservoir? The other question is: will the water in the borehole flow down into the lake when the shaft enters the cavity? Hard to see how it won’t, but if it does will it contaminate the lake with whatever residues were in the water that has melted into the shaft, the whole 100k years of deposition?
Good questions. No we haven’t drilled either hole fully yet, just made a start. The water in the borehole will not enter the lake if we balance the pressures, but even if it does, it is not a problem as all of the drilling water is melted snow that has been filtered and sterilised so there will be no contamination.
