The machine is called the "Village Drill," one of many models envisioned by Renouard and developed by BYU students six years ago.

The flow of water pumped into the borehole through the bedrock fissures will be closely monitored. The water pressure will enlarge the fissures, with geophones detecting micro-vibrations that reveal the direction in which the water is passing through the bedrock. Several geophones have been installed, with the deepest at depths of 1.2 and 1.1 kilometres, one at a depth of 670 metres, and the rest at depths of more than 300 metres at various locations in the Helsinki Metropolitan Area.

On the positive side, the retired content does offer more value overall and actually includes some big name autographs, like Brett Favre, Jerry Rice, Roger Staubach, Barry Sanders, and many others.

To reduce feed demand farmers are clearing out less productive animals and some markets are reporting stock that have not been finished properly: yet for producers to hang on to them any longer, in the absence of feed, would only store up more problems.

The classic tophammer method is renowned for high penetration rates in good drilling conditions and Atlas Copco is developing the method continuously. Exhaustive research into how impact energy can be transmitted into the drill bit in the most efficient way, with least possible stress, has resulted in a new generation of rock drills.

He said the two chiefs he had visited were happy with President Edgar Lungu’s effort to ensure that the relief food was taken to the people.

Structural problems with the borehole itself are much more serious. Modes of catastrophic failure generally involve the collapse of casings or screens, rendering the borehole unusable. Fortunately, such events occur relatively infrequently.

Best signing: Juan de Jongh – the former Stormer is a hot-stepping centre who is rock solid in defence. He featured for South Africa at the Rio Olympics, winning bronze, and will stick around when England take a few Wasps away, and will only add to a brilliant backline in Coventry.

To be fair, the bacteria and archaea dominate the show down there, and they are phenomenally alien compared to what we see up on the surface. From the biological samples obtained by the DCO, it seems that they have life cycles on near-geological timescales, which is to say that they are extremely long-lived, dwarfing that of anything that sees starlight. At the same time, their genetic diversity is comparable to that of communities on the surface. Although these crypto-communities of microorganisms differ all over the planet, they are ubiquitous – there’s nowhere on Earth that they are not.

Best signing: Faf de Klerk – the Springbok scrum-half may look like someone from Baywatch, with his long flowing blond locks, but he’ll be doing more than making sandcastles at Sale. His introduction could be the boost the Sharks need – fizzing around the breakdown and creating chances. He’s a proper player.
