According CEO Jay Whelan, CEO of Fitness Generator 1, this system was put into the market in California in 2009. According to the Green Revolution Company, 20 people can use fitness equipment 1 hour at the same time, which can generate 3 kilowatts of electricity. If these fitness equipment run for 4 hours every day, it can generate more than 300 kWh of energy every month, which can be used for lighting an ordinary home for half a year.

2. Within one year, the power generated by the bodybuilders can be used by 72 families 1 month.

3. Small gyms can even rely entirely on this equipment to generate electricity. At present, this power generation system is only suitable for exercise bikes.

The next step of Green Revolution Company is to improve the generator and make it suitable for fitness equipment including elliptical fitness machine and treadmill.

5. Some people can generate 105 watts in one breath. This competitive atmosphere can inspire people to do better, and they like the feeling of creating energy by themselves.
