That's why I mentioned household current for charging over night and the "unknown" of how long the battery would last.
What if the potential energy in the jar exceeds the extra energy that it takes to turn the pully that extra little bit? We can make assumptions all day. I just need to complete the project.
And remember, pullies drive superchargers too but does that extra work the engine does take away from hp? Not in the end result.
