Millions of people go to fitness centers. The energy they generate is wasted. The fitness equipment could have a built-in energy device (e.g. a battery charger) to utilize the energy wasted.
Well, army then is even a greater source of energy. Millions of people exercise all the day round We could and should find the way how to utilize this huge amount of wasted energy.
