The idea of using human-powered bikes to generate electricity has been floated, but there are several reasons why this isn't a viable option. Firstly, it's not a cost-effective way to harness energy. The money it would take to condition the energy into a usable form is greater than the money saved by reducing energy consumption. Secondly, humans can only generate a few hundred watts of power for a short amount of time, even at peak performance. This means it would take a lot of energy to produce enough electricity to power even simple appliances. Finally, there are more efficient and cheaper ways to generate energy.
| Characteristics | Values |
|---|---|
| Cost-effectiveness | Not cost-effective due to the high expense of conditioning the energy into a usable form |
| Energy output | Low energy output, even for athletes |
| Heat generation | Room would become unbearably hot |
| Return on investment | Low ROI due to the need for new hardware and the time required to sell harvested energy |
What You'll Learn
It's not cost-effective
The energy generated by people biking is minimal compared to other forms of energy production, and it is cheaper to use these other forms. For example, it takes a world champion cyclist all of their strength to pedal for two minutes to get a decently toasted slice of toast. The energy needed to build and power the bike-generators would likely not be paid back by the energy generated.
Additionally, the room where the biking was taking place would quickly become unbearably hot, and the energy produced would need to be stored in batteries, adding to the cost.
Overall, while it may seem like a good idea to harness the energy produced by people biking, it is not a cost-effective solution and there are more efficient ways to generate electricity.

It's not an efficient use of energy
If you were generating any reasonable amount of power, the room would quickly become unbearably hot. The more energy you get out of people, the more they will need to be kept comfortable, such as with a large fan to keep them cool while riding.
The resources required to implement such a system would be better invested in something like solar panels.

It's not a good return on investment
Even if millions of people were to bike every day, the amount of electricity generated would not be enough to make it a cost-effective way to harness energy. At peak performance, athletes can generate 200 watts of power, but only for a few seconds. The money it would take to condition the energy into a usable form is greater than the money that would be saved by reducing energy consumption.
It would also be incredibly inefficient to harvest the energy generated by people biking. The energy produced would have to be stored in a battery, and the room would become unbearably hot very quickly. The energy needed to build the bike-generators, as well as the expense of building them, would not be paid back by the energy generated.
There is an unlimited amount of "free" energy all around us, but it is cheaper to use other forms.

It's not a good use of human labour
Additionally, it's important to consider the amount of energy that would be needed to build the bike-generators and the food that the cyclists would need to eat to maintain their energy levels. The energy output simply wouldn't be enough to justify the expense.
Another issue is the heat that would be generated in the process. If a considerable amount of power was being generated, the room would quickly become unbearably hot.
Overall, while it may seem like a good idea to harness human power to generate electricity, it's just not a practical or efficient use of human labour. There are other forms of energy that are more cost-effective and efficient to harness, such as solar or wind power.

There are cheaper ways to generate energy
The amount of energy generated by people biking is likely to be very small compared to the total power consumed by human beings. In addition, the energy generated by people biking may not be enough to power a large fan to keep the rider cool, let alone contribute to the electricity grid.
Even if we were to harness the energy generated by people biking, the room would quickly become unbearably hot. Furthermore, the amount of energy generated by a person biking is likely to be very small, especially when compared to the energy output of electric car charging.
While it may be possible to hook up each bike to a battery that stores the electricity, the infrastructure required to implement such a system on a large scale would be costly and complex.
