The World´s Water Crises Explained

From Not Enough to Too Much, the World’s Water Crisis Explained

Many more cities than Cape Town face an uncertain future over water. But there are emerging solutions.

“Day Zero,” when at least a million homes in the city of Cape Town, South Africa, will no longer have any running water,

Global water crisis: Facts, FAQs, and how to help

Every child deserves clean water.

There’s nothing more essential to life on Earth than water. Yet, from Cape Town to Flint, Michigan, and from rural, sub-Saharan Africa to Asia’s teeming megacities, there’s a global water crisis.

Cities in the face of drought
More than five billion people could suffer water shortages by 2050, as a vicious combination of climate change, increased demand and wasteful inefficiencies plunge the world’s water supply under threat. The Telegraph investigates what can be done to prevent future crises.
Water becoming more valuable than gold

Advantages of Windgiant Wind Turbine Towers & Double Turbines: 

  1. - Windgigant turbine technology uses the acceleration of the airflow at all wind speeds
  2. - Efficient energy generation already at low wind, start up from 1.0 m/sec,
  3. - Due to flow acceleration high energy density with increased power coefficient per m2 turbine area.
  4. -  Very quiet operation of all Windgigant technologies below 45 dB(A) from 4 m distance.
  5. - No bird strike and no cast shadow/disco effect.
  6. - For landscape, design allows extended use of sites due to low headroom.
  7. - Reduced required shoring area due to high energy density to the state of the art.
  8. - Double Turbines also applicable for Smart City applications and in populated areas.
  9. - Depending on their size, wind turbine towers require smaller distances from residential areas. 
  10. - Wind Turbine Towers with distinctive added value of parallel water harvesting from wind flow.
  11. - In case of absolute windlessness, water extraction from wind flow by motorized turbine operation.
  12. Modular extensions for solar energy use, electric charging station, electric storage.


Modular expansion systems create added value

Windgigant wind energy systems can also be equipped with additional modular functions at a later point in time:

  1. - Electric charging station(s),
  2. - energy storage systems,
  3. Cash and cashless payment terminals
  4. - Used water treatment
  5. -  Installation of digital video walls on the wind turbine towers
  6. - Energy utilization via solar panels or photovoltaic modules at the wind turbine towers Area      

So that clean Energy and fresh Water can flow, where it is needed!


Clean energy from wind power and fresh water from wind flow & its entrained humidity components from 1 m/sec to 15 m/sec continuous operation.

Wind Turbine Towers with double safety control system parallel to the classical wind power operation:

All wind turbine towers from 30 kW to 1.6 MW have an additional safety control system per installed double turbine.

For all twin turbines, the wind flow supply is controlled via a hydraulically controlled lifting cylinder wind gate by "opening and closing" in the wind tower at the tower bottom to the respective twin turbines from 30 kW to 1.6 MW.

Via the PLC control system, the wind flow supply to the individual twin turbines is regulated via the wind gate depending on the wind speed.

  1. From startup at 1 m/sec wind speed, each individual twin turbine is switched on by opening the wind gate.
    2. From 12 m/sec to 15 m/sec strong wind, the respective wind gate closes between 25% to 50% for further controlled and safe wind power operation in strong wind.
    3. From 15 m/sec to 16 m/sec strong wind, the wind gate closes to each twin turbine.
    4. From 11-12 m/sec wind speed the wind gate opens again with connection of the respective twin turbine.

This double safety control concept is based on the combination of wind power and hydropower control technology that has been successfully used for decades.

Wind Turbine Towers with modular water harvesting technology:

Modular technology enables parallel water supply security with fresh water for humans, animals and all our environment.

Water extraction through condensation out of the air flow- from 10° C  up to 50° C - minimum air humidity 30% and higher

The condensation appears when the air cools down. If the air temperature decreases, less air humidity can be extracted (used for extraction?) than before. If the air humidity reaches 100%, the steam is omitted through the condensation process as so called 'mizzle droplets'. The water extracted through condensation is left for further usage as for example arbitration or drinking water preparation.

24h Water generation even in absolutele windless conditions by motorized double turbine operation, for all Wind TurbineTowers from 30 kW to 1.6 MW.

Due to the motorized fan operation of the double turbines, a continuousily controlled wind flow is avaiable for water produktion over 24 h, at least from 10° C to 50° C, even in absolute windlessness. Required humidity 30% and higher.
