How Electricity Is Generated - Lego model Okinawa Electric Power - Electrical Science Museum Commissioned work, March 2020 / Sachiko Akinaga

This is a LEGO model I made for kids to have fun learning how to generate electricity. It is one of two Lego models on permanent display at the Okinawa Electric Power Company - Electric Science Museum. Another model is ‘Electricity in Okinawa Life’.

Read the explanation panel in the model and follow the changes of "Mr.Water" to understand the mechanism of power generation. The good points are the rotating turbines, the large steel tower, and the expressions of the cute characters. There are also twin electric babies!

How Electricity Is Generated / size : W1,344 × D768 x H460 mm The water is heated by the boiler and becomes hot water, which then becomes high-temperature, high-pressure steam. The impeller of the turbine rotates with the power of steam, and the generator produces electricity with the rotational force. The steam that rotated the turbine is cooled by seawater to become water.

Boiler fuels : Mr.coal, Mr.oil, Mr.LNG (liquefied natural gas).

The water is heated by the boiler and becomes hot water, which then becomes high-temperature, high-pressure steam.

The power of steam turns the impeller of the turbine, and the generator produces electricity with the rotating power.

The steam that rotated the turbine is cooled by seawater to become water.
