“There is plenty of heat beneath our feet,” he says, “something like 20 billion times the energy that the world uses in one year.” But, Woskov notes, most studies of the accessibility of geothermal energy are based on current mechanical technology and its limitations. They do not consider that a breakthrough advance in drilling technology could make possible deeper, less expensive penetration, opening into what Woskov calls “an enormous reserve of energy, second only to fusion: base energy, available 24/7.”

- At Hounde, additional resource delineation is expected, notably at the Kari Pump, Kari Center and Kari West targets.
Big Black had noise-rock down to a science. The band essentially had no midrange. Bassist Dave Riley held down the low-end, while Steve Albini and Santiago Durango opted for extreme treble, which was made all the more piercing thanks to a penchant for playing with metal picks. With the industrial thump of drum machine “Roland” keeping rhythm, and a habit of setting off firecrackers on stage before playing, Big Black essentially created misanthropy you could sing along to. “Bad Penny” isn’t just an example of that, but a celebration of it, Albini’s narrator depicting himself as the worst kind of person to have in your life: “Think I fucked your girlfriend once…then I fucked all your friends’ girlfriends/ Now they hate you.” It’s a mean, nasty son of a bitch, and it’s also one of the best examples of how well their sonic assault could translate into a great rock song.
We show here that infancy is an optimal time for clinical circumcision because an infant’s low mobility facilitates the use of local anesthesia, sutures are not required, healing is quick, cosmetic outcome is usually excellent, costs are minimal, and complications are uncommon. The benefits of infant circumcision include prevention of urinary tract infections (a cause of renal scarring), reduction in risk of inflammatory foreskin conditions such as balanoposthitis, foreskin injuries, phimosis and paraphimosis. When the boy later becomes sexually active he has substantial protection against risk of HIV and other viral sexually transmitted infections such as genital herpes and oncogenic human papillomavirus, as well as penile cancer. The risk of cervical cancer in his female partner(s) is also reduced. Circumcision in adolescence or adulthood may evoke a fear of pain, penile damage or reduced sexual pleasure, even though unfounded. Time off work or school will be needed, cost is much greater, as are risks of complications, healing is slower, and stitches or tissue glue must be used.
A 27-horsepower Kohler EFI gas engine powers the drill, which includes a powerful 3,000- psi hydraulic system. The drill’s 12.5-gpm hydraulic power pack achieves a rotary speed of 100 rpm. The system also provides the drill’s hydraulic winch with 1,500 pounds of pull for raising the automatic hammer.

Best signing: Liam Williams – star of the Lions tour, he set up THAT try in the first Test, and is now ready to rock the Premiership. Brilliant at wing or fullback he will frighten defences all year. The best signing of the summer from any club, on paper.
Circumcision in infancy avoids any embarrassment of having it done later, as well as anxieties about pain, complications and adverse sexual effects, even though these are minimal or not supported by evidence. It also avoids arguments about whether there might be adverse psychological consequences for MC performed later in childhood. And absence from work or school is avoided.
Both founders told me they expect to reap enormous cost reductions from expanding production — activities that involve buying materials more cheaply in bulk and assembling units on automated factory lines instead of building them by hand, as is the case now. Design advances could wring out other costs. “Maintenance is very expensive,” Wurzbacher said. “Right now, if we exchange the filters in the collectors, we have to rent a crane, and that’s a lot of man-hours. In the next-generation units, we have improved that a lot, so relatively small design changes could cut the costs of maintenance by a factor of three.” Climeworks also intends to derive savings from improvements to crucial materials, like the sorbent that catches the CO₂. At the moment, the company’s technology requires that the temperature inside the units be raised periodically to about 100 degrees Celsius to release CO₂ from the sorbent so it can be drawn off and stored. If the process can be done at a lower temperature, the units will use less energy, and the life of the materials should be extended, further driving down costs.
2018 was guided to be a transition year for the heap leach operation with greater priority given to the CIL construction activities, particularly in the second half of the year as the main goal was to stack ore from lower grade stockpiles. However, Ity’s heap leach operation performed above expectations, particularly in Q4-2018, as mining was opportunistically conducted based on equipment availability and the good progress made on Ity CIL construction.
- The 11kV switch room and 11kV overhead power line have been commissioned, the 90kV transmission line construction is nearly complete, and the back-up power station has been commissioned.
