SUMMARY

The discussion centers on the energy output of a dynamo while cycling, specifically questioning the validity of a reading of 138 watts on an exercise bike. It is established that a professional cyclist can produce approximately 250 watts, which is significantly higher than the output of small wind generators, typically around 100 watts. The conversation clarifies that the comparison should be made with small-scale wind turbines, as larger wind farms operate in the megawatt range. This indicates that the energy output from cycling can be substantial compared to smaller wind energy systems.

PREREQUISITES
  • Understanding of basic physics concepts related to energy and power
  • Familiarity with cycling performance metrics
  • Knowledge of wind turbine energy output specifications
  • Awareness of the differences between small and large-scale energy generation systems
NEXT STEPS
  • Research the energy output capabilities of various types of wind turbines
  • Explore the physics of human power generation in cycling
  • Learn about the efficiency of different types of exercise bikes
  • Investigate the comparison of energy outputs between human and mechanical systems
USEFUL FOR

Cyclists, fitness enthusiasts, renewable energy advocates, and anyone interested in understanding the dynamics of energy generation through human effort compared to mechanical systems.

I was on an exercise bike in the gym the other day and on the screen it said I was generating 138 watts, and as you can imagine that's a pretty big value,lol. I wasn't cycling that fast either. My question is, is this value possible ?

sorry if this is a bland question but I know a wind generator gets about 100 watts, so I am just trying to get my head around this. Thanks in advance.

Yes that's reasonable for cycling.
One horsepower is 750W, a professional cyclist can produce about 1/3Hp = 250W
 
but how can this number be so much greater than a wind generator ?
 
What do you mean? What kind of wind generator are you talking about? Here's a relatively inexpensive residential wind turbine that puts out 400w.

Wind farm generators are rated by mega-watts. You must be referring to a very small wind generator.
