I wonder how much more efficient it would be to mechanically hook the pedals up to the spinny part of the blender?

A lot more efficient. This sounds like a novelty, but in reality, bicycles are for endurance more than sprint. Using a battery as a buffer would enable a customer to pedal until the battery is charged enough to blend a smoothy. That could be a slow 20 minutes cycle out a 5 minutes sprint.

A lot. In fact most "pedal smoothie machines" you see work that way.

But I wanted to build it the way I did to be educational as well. When kids struggle after 15 seconds I say "You'd have to pedal a LOT harder continuously to power your xbox. That really gets them thinking.
