Imagine this your stackmat batteries die. You just open your cube swap the batteries and by the next time they die the ones in your cube are ready to be put back in the timer.
Let's say it did generate some electricity. Now then why would you expect it to turn as fast as your main speed cubes? Instead, think of an unmodded storebought with even more friction and less (probably close to none) cutting corner capabilities.
maybe we can use the produced electricity for the cube itself. so when we are not at home, it can get solved itself and do some avg's of 12 while we can't reach it or don't have to do some avgs.
