In the Japanese manga Giant Robo, a Shizuma drive is a clean energy device that replaces all other power sources. I was commissioned to build this by a friend and fan of the show.
This project was a challenge. Especially figuring a way to suspend a red ball perfectly in the middle of a cylinder of "liquid". The solution was using a 2-part acrylic fake water kit people use for artificial flower arrangements. The end caps that hold the LED lights were scratch built from found parts.
