Overall demand was flat and wholesale power prices were weak, but technological advances and rapidly declining costs made renewable energy highly competitive, prompting a widespread shift toward wind and solar power. The world’s P&U companies encountered significant challenges during the past decade. We then examine the impact of COVID-19 on the sector to understand how companies should adjust their strategies to prosper in the new post-pandemic reality.

In this report, we analyze the historical performances of leading European and North American P&U companies to identify the key value creation drivers during the pre-COVID-19 period. Companies that reach scale in a decarbonizing world, adopt new data-driven solutions, prioritize best-in-class cost reduction programs and cash management, and identify new pockets of value will emerge as value creation leaders in the coming decade. Regardless of how quickly the world recovers from the pandemic, we expect the crisis to accelerate this trend. When the COVID-19 pandemic hit, the industry was in the midst of a fundamental shift away from centralized conventional generation and toward a more distributed and digital era. And they have responded by changing their business models, embracing new technologies to cut costs, and expanding into additional market areas.Ĭrises have a way of creating or accelerating transformational change. P&U players have weathered similar shocks before.

How to by BCG: Turn Insights into Action.Technology, Media, and Telecommunications.Using a gin pole and ingenuity two men can unload and restack in the barn a hay truck in nothing flat. Basically a small gasoline motor spins a capstan spool. The guys out west can best describe the capstan and winch line method of unloading bales of hay from a truck. Anything that will engage, and then disengage, and let gravity do the dirty work. The capstan (rope and wheel) system could be used too. Cylinder is brought back to the bottom where it catches the weight and we start all over again. When the cylinder hits maximum a lever engages and releases the weight. The rod has a catch that picks up the weight. It could be something as simple as a hydraulic cylinder that lifts a rod. When I first read this thread my thoughts went back to pictures of pier (pile) drivers of the nineteenth century. When the saw cuts through it pulls the chain taught and voila! A chain runs from that to the saw frame that moves. A standard electrical, plastic even, switch with a hole drilled in the lever. ( I don't know who came up with this concept but it supports my belief that some of the best engineers never set foot in a college classroom.)Ī friend of mine has the trickest little shut off for his band saw. Don't spend more than $50 and, oh, have it by Thursday." "Design and build a machine to vertically transfer 500 ft-lb of energy 6 times/minute. I don't know who came up with this concept but it supports my belief that some of the best engineers never set foot in a college classroom. Or maybe used some lubricant on the rope. He may have used a heavy weight and low lift height to minimize the number of wraps. If not, your only choice would be to run like hell.
But as I type this, I'm wondering if you lifted the weight high and there were many wraps, if the "clutch" would release reliably.
It was sitting in my neighbor's yard one night and I surmised how it worked. When the weight was high enough, you let go of the rope, the rope loses it grip on the rim, and the weight drops. When you pulled on the loose end of the rope, the wraps tightened on the rim, causing the rotating rim to wind up rope and raise the weight. When the rope wraps were loose, the lift mechanism was in neutral. In use, the PTO ran continuously, and therefore, so did the rim. The rope wrapped around the rim served as the clutch. Ī heavy rope was tied to the weight, routed up over the top of the mast, down to the rim, and wrapped around the rim once or twice. He mounted a tall mast with a sliding weight to the old axle. For Stephan's use it would be mounted behind the tractor, parallel to the tractor's rear axle, with the drive shaft connected to the PTO. He took an old rear axle/differential assembly with an empty rim still attached to one drum. I think it may be a less sophisticated version of your description.

I don't quite follow your description but it reminds me of a home made well driver I saw about 25 yrs ago.
