Abstract: The invention relates to a method for introducing a boring channel in the ground by means of an earth boring device, wherein the earth boring device has a boring head which is moved to introduce the boring channel in the ground, and the method comprises the steps: a) detecting obstacles in front of and/or next to the boring head; b) displaying the position of a detected obstacle relative to the boring head; c) issuing a shutdown warning if the distance between the detected obstacle and the boring head is less than a first, in particular selectable, distance; d) stopping boring of the boring channel when a shutdown warning is issued; e) verifying an acknowledgment for continued introduction of the boring channel when a shutdown warning has been issued and boring stopped; and f) continuing the introduction of the boring channel upon successful verification of the acknowledgment.

Abstract: A body assembly has a vehicle structural element configured to mechanically couple to an energy storage housing. At least one guide element redirects a gas flow emerging from at least one exit port of the energy storage housing. The at least one exit port is configured to pass gas from within the energy storage housing to an external environment external to the energy storage housing.

Abstract: The method and system for removing CO2 from the atmosphere or the ocean having the steps of, feeding a solid oxide fuel cell (SOFC) system with a gaseous hydrocarbon feed, converting the gaseous hydrocarbon feed in the SOFC system into an anode exhaust stream having carbon dioxide CO2, the SOFC system thereby producing electricity; injecting the anode exhaust stream as an injection gas into an underground coal bed; in the underground coal bed the injection gas causing coal bed methane (CBM) to desorb from the coal and CO2 to adsorb onto the coal; extracting the coal bed methane (CBM) from the underground coal bed; and discharging a production gas having the coal bed methane (CBM) from the underground coal bed.

Abstract: A golf ball which is easily identified without touching the ball, rolling it over or picking it up, even though it may lie in deep rough or be almost completely buried in a sand trap. A method of making a better golf shot comprising providing a golf ball with a multitude of separate and distinct identifying marks on the cover being spaced-apart so that at least one mark is visible to the eye no matter how the ball lies, and whether or not it lies in deep rough or is almost completely buried in a sand trap, and a method whereby the golfer focuses his or her eyes on a single selected mark without distraction from other marks.
