    Do you see these wind turbines? Disgusting! An asparagus-isation of the landscape!

      Doesn’t Germany dig huge open pit mines, and then build wind turbines on them afterwards? I feel they could save a lot of environmental issues if they just went straight to the turbines.

        But don’t you think about the children work places???

        Sooo many people work in coal power! You can’t just stop subsidises and force them to look for other jobs! /s

    Pumpjacks do have some interesting design features. Everyone knows about the counterweight lever action, but it also has a neat check valve system in the well itself. Think of a toilet reservoir stopper but with another in the tank with a reciprocating piston up and down the height of the tank and a side pipe. The downward action causes the bottom plunger to close by the hydraulic force of the fluid and prevents flow back into the well or through the side channel.

    Likewise on the upstroke, the suction action opens the top and bottom valve and sucks the fluid upwards like in a drinking straw until it reaches the top of the stroke, then pushes the fluid through the side channel on the next downstroke which then connects farther up the pipe, which then goes up again on the upstroke. This is all done by hydraulic pressure in the well and has no moving machinery (other than the motor aboveground) and only needs periodic O-ring replacement.

    Thus, it is acting as a positive displacement pump (like a heart beating in a sense but less complicated).

      I’ve been getting ads from BP about how they’ll be done electrifying their oil wells in the United States by the end of the year or something. Technically a good thing but the obvious green washing is so gross. Them being electric doesn’t change what the wells make/contribute to.

    Where in the world are pumpjacks clustered like that? There’s got to be dozens of them!

        This is my favorite part

        Most native vegetation is gone from the oil field, with the most dense operational areas being almost completely barren except for pumping units, drilling pads, evaporation ponds, storage tanks, steam generators, and associated equipment.

    I’m a big fan of wind turbines, but if you happen to dislike both, the oil drillers are usually a lot more clustered and overall fewer.
