What immediate actions can we take to address energy-water nexus challenges?

Energy and water are both key resources for societies all around the world, and complex interdependencies exist between the two systems.  This has been coined the “energy-water nexus.”  At its simplest, this can be broken down into “water for energy” - water utilization for cooling thermoelectric power plants, hydraulic fracturing, geothermal energy, enhanced oil recovery, biomass, and hydropower - and “energy for water” - energy utilization for water management, treatment, desalination, distribution, and heating.

In the face of climate change, the relationship between energy and water systems will continue to evolve, driven by mitigation measures affecting energy portfolios and technologies, and adaptation measures addressing changing precipitation and temperature patterns.  This contest seeks high-impact proposals providing an immediate, feasible action that can be taken to address any local, national, regional, or international challenge at the nexus of energy and water.

The Tidal Pump, now at proof of concept, aims to shift large volumes of liquid in the ocean at lowest possible cost using new technology.
The SunSaluter is a low-cost solar panel rotator which boosts efficiency by 30% and produces four liters of clean drinking water each day!
Diatom Algae produce about 20 to 25% of all Oxygen in the world. All the oxygen required to treat sewage can be produced by Diatoms.
Systems thinking leads to a plan to keep Hoover Dam as viable source of clean water and energy.
SUFI provides an integrated hub that sustainably manages the urban energy-water-food nexus in an era of climate change.
Deep water electrolysis produces hydrogen with the potential to produce mechanical, electrical and gravitational energy as well as water.
By capturing water values of energy planning in water-scarce places, economics can guide sustainable and pro-poor water and energy policies
I propose to combine CHP biogas cogeneration systems in wastewater treatment plants to power water desalination systems.
