AI Thread Summary
Electric mining equipment is gaining traction, with major developments like Liebherr's electric excavator and Caterpillar's 240-ton electric haul truck. The collaboration between Liebherr and Fortescue aims to introduce the world’s first autonomous electric haul truck, while EPCA plans to convert 50-70 mining trucks to electric power each year. Innovations such as electric trolley-assist haul trucks utilizing regenerative braking systems are also being explored. Although coal mining has been electrified for years, open-pit mining remains largely reliant on diesel-powered mobile equipment. The transition to electric solutions is expected to be gradual, aligning with advancements in power storage technology.

Coal mining has been heavily electric for many years. However, it's a big industry and I'm sure there's more room to electrify. Open pit mining is not electrified at all concerning mobile equipment in my corner of the world. Conveyors and anything stationary is electric.
 
I recommend you become a subscriber to Engineering with Rosie.

Those ore trains in Western Australia are now remote controlled from HQ in Perth. No sudden step change is required. The electric infinity train can be introduced progressively as new power units with storage are developed and become available to replace the "end of life" diesel locomotives being retired.
 

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
