Tower Pulls Drinking Water Out of Thin Air

People in the Ethiopia area are spending 40 billion hours per year trying to figure out how to collect clean drinking water.  This is a huge ongoing problem for the people that live in these areas because they are not able to get enough drinking water to survive. Well now there is a new solution to a problem that affects nearly one billion people in Africa:  Warka Water towers.  These inexpensive, about $500 USD, 30 foot tall vase looking structures can provide up to 25 gallons of clean drinking water per day.  The concept of producing clean drinking water is not a new technology, it is just improved tremendously.  The structure is made up of a biodegradable material and can be easily cleaned by one person.  In Africa there sometimes can be a 50 degree temperature change from day time to night time.  With that huge fluctuation the towers are built to collect the condensation in the mesh materials inside the towers and that is what produces the clean drinking water.  There are a few questions about the Warka Water towers like, if the towers can hold up in the sometimes extreme outside conditions.  Arturo Vittori, the inventor of these products, believes that the towers will hold up very well because they are built with a strong mesh material that is also biodegradable.  With that design it ensures that the towers will produce consistent clean drinking water for the people in the area.

The Eiffel Tower goes Green!

In today’s society, the new concept people are striving for is green energy. Green energy is simply using the natural resources to create energy without the offset of pollution and waste… and now the majestic Eiffel Tower has made the jump and gone green! This recognizable worldwide icon has been equipped with wind turbines suspended 400 feet above the ground. These turbines were placed on the second level so they can capture the most possible wind to maximize the energy output. These two turbines were installed the old fashion way by using ropes and pulley systems while a team of people guided them all the way up. The whole installation process was relatively simple one as the installation team contracted for this project had previous experience working on the Tower; however, with that said the team still dealt with a few problems. One of those was being able to get the sixteen foot blades for the turbine up to the second level where the turbines would be placed. This became difficult because the workers had to deal with a pretty small range of room all the way up. The other problem the company dealt with was figuring out the proper way to secure the wind turbine to the tower because they were not building on a conventional building. Instead of the contractors using concrete to secure the motors, they built a steel foundation that was required to absorb any vibrations that may occur. With all the construction completed in February 2015, the turbines produce a small percentage of power needed to operate the tower, this is an excellent way to get more people around the world informed and involved in sustainable energy.
