Power Lag
by Fantomrat
Power Lag is a NeoForge joke mod that generates energy by sacrificing the frame rate of the player who runs it, and it can drain nearby players as well.
What it does
An FPS Generator is placed in the world and produces energy at the cost of the frame rate on its owner's screen. Energy output is described by the author as high, but it is paired with heavy drawbacks: the generator needs lava to run, its build is listed as complicated and expensive, and it is far from a clean source. Installation requires NeoForge, and the mod is built for Minecraft 1.21.1 only.
The mod supports multiplayer, so a generator can convert the frame rate of nearby players into energy. The author presents it as a prank tool for trolling friends, and notes that whether friendships survive the experience is an open question. Power Lag runs on the client and server, so both the server and every player need it. The code is not open source; the mod is released under All rights reserved.
