Longwall Coal Cutting Machine

Coal cutting machines are often used underground to assist in breaking down the coal so that it can be loaded out. A coal cutter cuts into a portion of the seam, making a slot along the coal face, after which the remaining part of the coal is cut down by the use of hand or pneumatic picks or is broken down by explosives.

Direct CO2 capture machines could use 'a quarter of

Machines that suck CO2 directly from the air could cut the cost of meeting global climate goals, a new study finds, but they would need as much as a quarter of global energy supplies in 2100. The research, published today in Nature Communications, is the first to explore the use of direct air capture (DAC) in multiple computer models.
