James Watt's Weather Vane

Origin
James Watt was a inventor and engineer who created the Watt steam engine, which transformed the course of the Industrial Revolution. Watt realized engines in existence then wasted too much energy continually cooling and reheating the cylinder. His design had the condenser separate from the main components, allowing him to avoid energy loss and increase efficiency. The SI unit of power, the watt, is named in his honor.

Effects
Even the smallest puffs of wind will send this weather vane spinning incredibly quickly. Becomes incredibly hot after a while.
