You can thank Street Outlaws for more than a few noteworthy builds; ones that inspire us from here to the moon with some of the most ridiculous power ratings pouring out of the least likely of engine bays – Farmtruck is no exception. It’s as if the truck was built to deceive – everything about the exterior screams beater (tried-and-true) and had you not noticed the huge slabs of rubber wrapped around the custom rear wheels, you’d never know what hit you. The authentic wear and tear of a lifetime of abuse effectively conceals the 600hp-plus that sums up to a Chevy long-bed with enough cajones to pull the front wheels off the ground.

Spain’s Guardia Civil is also investigating whether the borehole that Julen fell into was built illegally.

The key to installing a reliable and efficient borehole is understanding the hydrogeology of the site, and assessing the aquifer potential and aquifer properties. The geology of the UK is highly variable, but we are fortunate to benefit from some excellent aquifers on both a local and regional scale. The major Chalk, Limestone and Sandstone aquifers found in the South and Midlands in particular provide substantial yields, potentially in the region of 1,000m3/day or more. Good yields can be obtained from other formations too, and at a local scale there might be several options for developing an independent water supply.

Shallow, deep or long holes are drilled with barely any change in capacity and hammer casing and stiff drill tubes offer good guidance for the hammer and drill bit, minimising in-hole deviation. Thus, blasting patterns and use of explosives can be optimised, increasing the yield of rock at a reduced cost per meter or footage drilled. The optimized annulus between the drill tubes and the hole wall ensures efficient hole cleaning under most rock conditions, including long or deep holes or holes filled with water.

Climeworks’s current goal is to remove 1 percent of the world’s annual CO₂ emissions by the mid 2020s. Yet meeting such a benchmark, if it’s even possible, would require bringing the cost of direct air capture down by nearly an order of magnitude while maintaining and expanding their roster of clients substantially. At the moment, Wurzbacher and Gebald have planned for several generations of Climeworks machines, with each new model promising declining prices. “Basically, we have a road map — $600, down to $400, down to $300 and $200 a ton,” Wurzbacher said. “This is over the next five years. Down to $200 we know quite well what we’re doing.” And beyond $200, Wurzbacher suggested, things get murkier. To move below that price would depend on “new developments” in technology or manufacturing.

- Sustaining capital for continuing operations for 2018 increased compared to the corresponding period of 2017 due to the addition of Hounde and an increase at Agbaou, which were offset by a decrease at Ity as illustrated in the below table. Further details by assets are provided in the above mine sections.

For the moment, skeptics of Climeworks’s business plan are correct: The company is not turning a profit. To build and install the 18 units at Hinwil, hand-assembled in a second-floor workshop in Zurich, cost between $3 million and $4 million, which is the primary reason it costs the firm between $500 and $600 to remove a metric ton of CO₂ from the air. Even as the company has attracted about $50 million in private investments and grants, it faces the same daunting task that confronted Carl Bosch a century ago: How much can it bring costs down? And how fast can it scale up?

Always optimistic, Rick observes that it is not a huge collapse, but concedes that the equipment has definitely moved away from the deck.

- Operating Cash Flow before non-cash working capital of $53m or $0.49/share in Q4; FY-2018 up 64% over 2017 to $261m or 2.43/share

Indeed, there’s still plenty more left to discover, including describing and understanding what exactly it is that’s living down there. Some are thriving, while others are those aforementioned “zombies” – organisms kept in a suspended, barely active state, just about surviving. What exactly is the true proportion of thrivers to survivors? Where to they get their energy from? How does life even move around below there, and what impact does it all have on the surface world?

Once drilling is completed, techniques such as acidising or targeted air lifting (surging) may be used to enhance the yield and efficiency of the borehole. This part of the construction phase is referred to as borehole ‘development’.

The awareness during Victorian times of a wide array of medical benefits from MC, including prevention of syphilis and better hygiene, led to a rise in its popularity in Anglo-Saxon populations in the 19th century [7, 9], continuing today in the USA in particular, where the majority of infant boys are circumcised [3, 4]. In the UK circumcision is more common in the wealthier upper-classes, marking the fact that a doctor attended the birth rather than a mid-wife.
