Picking up the context
This is a follow-up question to the technologically accurate watermill clock, available here. In this case, we're not using water to make clocks, but wind! Wind will be the power source to... power the clock mechanically. So let's lift off into the world of physics and engineering together!
The watermill clock had issues having a simple, yet physically correct mechanism to display the time, given a constant input current. In this case however, I believe the main issue is having the power input being constant and reliable in the first place. Indeed, it's not like water where you could always put it in a storage and use valves, the container's shape or Mariotte's bottles. Wind is chaotic by nature, having strong and weak times, but it's also not a thing you can contain in a tank like most other materials.
Therefore, how can wind input be made constant in order to accurately power a mechanical clock?
In order to answer, I guess we have to think about how to keep a strong wind lower to not overpower the mechanisms, and how to keep in some power to keep the clock working during lowtimes. There are also turbulencies, and well, wind orientation to take into account. There can be other technical issues I haven't pictured, so tell and find a solution about them if I've missed one.
Here are some intel that should help you understand the intentions :
- The clock that will use this system is your typical town's council or railway station clock. It's near the coastline (beach height), typically in an oceanic climate. It's relatively big, and therefore requires a little more power than your wrist-watch or kitchen clock.
- Since we're talking about time-keeping, accuracy is paramount, both in stability (no variation over time) and precision. The more accurate and constant you can make, the better. I'm expecting a precision in the order of minutes or half-minutes at the very least, though more accurate is better.
- Technology up to today is available, but no oil, gas (outside wind, obviously) or electricity component however! The key point is transforming wind forces into mechanical power, so you can't use a regular wind turbine and batteries to power electrically the clock; That'd be just too simple 🐶.
- The shape and size of the wind engine can be whichever you like better : Windmill, wind turbine, cylinders, weather vane... Just don't make it 1km long and gold plated :p.
- The longer you can keep the clock alive with low or no wind, the better, but reach first the minimal accuracy criteria.
- Focus your efforts on making the wind give a constant mechanical force. You can talk about its relationship with the clock mechanisms, especially if it's important to accuracy or power conversion : Springs, pendulums, I don't know! But just remember the clock itself is not the main point.
- If the wind engine is not too expensive to repair or replace, it can take a hit from heavy storms (let's say > ~90km/h or ~50kn). The clock's core should not fear damage by receiving too much pressure in, though.
Ideally, your answer should go beyond theory and put things into practice. Talking about the base idea is a nice starting point, but it's to be put in a place with the environmental context above, therefore some dimensional specs would sure be helpful to me ^^.
If one of the above condition prevents you from reaching the goal (making a wind-powered clock), you can alter it slightly in order to reach it. For instance, if wind speed is just too low even on seaside, you can tell you had to increase it a little for the purpose of answering the question. After all, a partially successful answer is better than none 🦋.
