What is expected to happen in the future?

When we humans move about, we generate energy. But is there any way that all that energy we generate could be harnessed and used? It seems there is. And that’s being tested.(25)The energy players expend on a football pitch and other local areas is being turned into a source of electrical power.
    Millions of Brazilians expended plenty of energy during the World Cup, celebrating victories and ultimately commiserating in defeat as their side crashed out in the semifinals.(26)But what if all of their energy in jumping up and down hasn’t gone to waste for the public good? A scientific initiative backed by the Anglo-Dutch giant Shell means these kids aren’t running around the community football pitch aimlessly. Every time a boot hit a turf, it counts toward something.
