In an spinning session every person is producing a power in a range of 100 to 250 or more Watts (https://en.wikipedia.org/wiki/Watt). At the same time they are producing heat that increases the temperature of the room that must be cooled properly with the air conditioning system (http://www.ifafitness.com/health/temperature.htm).
Stationary bikes have a mechanism for producing resistence either by mechanic friction or magnetic. Lets change the way to produce resistence by applying a dynamo (https://en.wikipedia.org/wiki/Dynamo) to the byke. The resistance can now be be set using a regulator.
The electricity produced (direct current) can be converted to alternative current utilized by the climate system by means of inverters (https://en.wikipedia.org/wiki/Power_inverter).
At the same time we can measure the electrical energy produced by each person utilizing sensors attached to a microcontroller such as Arduino or Raspberry PI. The measures are sent to an information system that registers the data using…
