   The device works off-grid so could prove useful in places with limited resources. Nearly 2 billion people lack clean drinking water, and 775 million live without electricity around the world.

3. Atmospheric water generator - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_water_generator

   State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.

4. Pumped-storage hydroelectricity - Wikipedia

   en.wikipedia.org/wiki/Pumped-storage...

   Electricity is created when water is let in via a reversible turbine integrated into the sphere. During off-peak hours, the turbine changes direction and pumps the water out again, using "surplus" electricity from the grid. The quantity of power created when water is let in, grows proportionally to the height of the column of water above the ...

   Grid connected set-ups with net purchase and sale [22] All set-ups mentioned can work either on a single power plant or a combination of power plants (in which case it is called a hybrid power system). For safety, grid-connected set-ups must automatically switch off or enter an "anti-islanding mode" when there is a failure of the mains power ...
