Clockwork energy storage ratio

What does a clockwork machine do?

A set of gears through which the spring's energy is released. The gears control how quickly (or slowly) a clockwork machine can do things, but they also control how much force it can produce (for climbing inclines, perhaps). A mechanism the gears drive that makes the device do useful or interesting things.

What are the performance parameters of energy storage capacity?

Our findings show that energy storage capacity cost and discharge efficiency are the most important performance parameters. Charge/discharge capacity cost and charge efficiency play secondary roles. Energy capacity costs must be ≤US$20 kWh –1 to reduce electricity costs by ≥10%.

Are clockwork toys any good?

Clockwork toys aren't anything like as well made (or as impressive) and if you get more than a minute or two's entertainment for your thirty seconds or so of winding you're doing well. Generally, more interesting clockwork devices that run for longer have bigger and sturdier springs capable of storing much more energy.

How do clockwork mechanisms work?

Clockwork mechanisms use gears in both these ways. In a pocket watch, gears transform the speed of a rotating shaft so it drives the second hand at one speed, the minute hand at 1/60 that speed, and the hour hand at 1/3600 the speed.

Can energy storage technologies help a cost-effective electricity system decarbonization?

Other work has indicated that energy storage technologies with longer storage durations, lower energy storage capacity costs and the ability to decouple power and energy capacity scaling could enable cost-effective electricity system decarbonization with all energy supplied by VRE 8, 9, 10.

How old is clockwork technology?

Clockwork has certainly stood the test of time: the earliest clockwork device, known as the Antikythera mechanism, dates from ancient Greece and is thought to be at least 2000 years old. Why has clockwork technology been such a firm favorite for so long? How exactly does it work? Let's take a closer look!
