Kinetic Dynamo

The Kinetic Dynamo is a power generation block added by Immersive Engineering that passively generates Redstone Flux (RF) from the environment. A Windmill, Water Wheel, or Improved Windmill can be attached by placing it on any of the dynamo's south, west, north, or east sides. One dynamo can support multiple components.

The Kinetic Dynamo's power output is proportional to how fast the attached structure spins, and other factors.

Options
The Water Wheel is a 7-block-diameter structure that's turned by flowing water. The more water is flowing around the wheel, the faster it turns and the more RF it generates. A Kinetic Dynamo can support up to three Water Wheels on a side.

Windmills are the other pairing option for the Kinetic Dynamo. Windmills harness the weather for power; their output is increased during rain and doubled during thunderstorms. Beyond that, Immersive Engineering version 0.12-77 brought an update to how windmills work and how much power they produce.

Power output
For the Water Wheel to output its maximum of ~30 RF/tick per wheel, flowing water should contact as many of its edges as possible, and all should turn it the same way. Dipping one edge in a waterfall works, but not nearly as well as letting water cascade over the entire wheel and run back under.

Windmill power output increases during rain, and during thunderstorms it doubles. Blocking a Windmill with another substantially decreases its output.

Before 0.12-77
Windmills generate more power at higher elevations, and the standard Windmill can be crafted into an Improved Windmill to double its power output.

0.12-77 and after
Wind power no longer scales with elevation, and there is only one Windmill, which is upgradable by using up to 8 Windmill Sails on it.

This update brought no change to Water Wheels.
