Piggybank-Battery

The Piggybank-Battery is an invention of Gyro Gearloose. 
==Description==
This piggybank-like machine created by Gyro Gearloose had the ability to convert coins put into it into pure electric energy, growing as it did so until it was larger than a real-life hog. It was used in 2017 to power the Money Bin's failing defence system and prevent the Beagle Boys and Greedy Gangsters, Inc. from destroying it, with John D. Rockerduck appealing to the inhabitants of Duckburg to each make a small donation to save the old concrete cube — which he argued had become, however one might feel about it or its owner, an essential part of Duckburg's identity.
==Behind the scenes==
The Piggybank-Battery appears in the 2017 story Under Siege!.
