On February 29, 2016, the EXP Dynamo Generator was put in the game with version 0.5.22. It had no functionality but was intended to produce battery power based on how fast you move. It's been stuck in limbo ever since, just sitting around and taking up space. You can't even scrap it for resources. It's objectively the worst block in the game! Now that we have battery-sucking anti-gravity blocks in the game, now would be the best time to fix the Dynamo Generator, allowing anti-grav techs to stay in the air indefinitely as long as they keep moving.
