I have always been fascinated by GBC modules. Whenever I came across a video showing multiple modules connected together, I immediately clicked on it and found it completely mesmerizing to watch. What I enjoyed most were the modules that introduced truly original mechanical ways of moving the balls from point A to point B.

At first, even simple lifts felt fresh and exciting. Over time, however, it seemed to me that genuinely new mechanical transport principles became less common. On the other hand, the visual themes of modules have become more and more creative and original. This made me wonder whether it is still possible to come up with a completely new approach - something where the balls are not lifted by a marble pump, not moved by a brick-built wave, not pushed by a spiral, and so on.

Eventually, I came up with an idea that I would like to share with you.

**Momentum Launcher – Proof of Concept**

This module spins a ball to build up momentum and then releases it onto an inclined track, allowing it to travel upward into a basket. Almost every aspect of the module still needs refinement. The feeder is currently quite improvised, the ball tends to bounce while being accelerated, and the biggest challenge will be achieving reliable placement of the spinning ball onto the track.

Even so, the concept already shows that the idea is workable and could become a nice GBC module with further development.

Unfortunately, I have a limited number of parts and even less time, so progress toward a finished module is quite slow. The original idea has been in my head for several years, and only recently I managed to build at least a partial proof of concept. That is also why I decided to share it here even in this unfinished state - so that if the idea catches someone’s interest, they might continue exploring and developing this principle further.
