It may have started with kids on Third World roundabouts that could not only create energy, but pump water from underground springs or boreholes.
We waste energy in landfills when it could be burned, the smoke cleaned and the heat used to boil water for steam-driven generators.
What’s nice about this is that it brings communities together instead of dividing them between those with jobs and so-called ‘takers’ on food stamps whose jobs have been outsourced.
