This x1000
I actually built a bicycle generator (an AC motor with a belt around the rear wheel) and would sell organic smoothies at music festivals. The fun part was the buyer had to pedal the bike to generate the electricty to power the blender to make the smoothie.
Even with only a 150w blender, fit adults had to work HARD to get the smoothie.. well.. smooth.
Kids basically couldn't do it, or not well enough.
And that was about 20-30 seconds of pedalling.
- Rebelgecko 6y agoI wonder how much more efficient it would be to mechanically hook the pedals up to the spinny part of the blender?
- raffraffraff 6y agoA 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.

- grecy 6y agoA 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.
