Long gone are the days of after school science projects as two high
school students from Knoxville, Tennessee presented President Obama in
Washington, D.C. with their completion of a micro-scale, hydro-electric
powered water filter system that is designed to clean surface water.
The water purification design as explained by one student of two
student team, quoted from WATE.com, states, �basically it uses the
flowing current of the water to spin a water wheel and that electricity
is used then to turn around purify the water itself.�
The design of the water filter system
itself is a sustainable system that operates on its own power source.
Electricity is generated from the water wheel and the water is then
pumped through an ultraviolet disinfection system. The invention of this
purification system is in effort to create and design a more
cost-effective and easier way to purify waters in developing countries
where a reliable energy source isn�t always available.
Although the water purification system was a scaled design, President
Obama commented on student�s presentation with, as quoted from
WATE.com, Knoxville Tennessee�s news source, �[This design] could
potentially be used for an entire community. This was a very practical
application of knowledge.�
Access to clean drinking water is a crisis experienced in many
developing countries and although this was a scaled experiment it was a
definite step and notable effort to bring purified water to countries in
need through use of a reliable, self-sustaining system.
