invention of a device which charges mobile phones with
water.
Augustine Otuokwa Ogar, a graduate of the
University of Calabar (UNICAL), has developed a
cool device able to charge mobile phones » with
water.
The device, powered through a hydroelectric energy source,
was created from materials obtained locally.
Calabar Reporters got an idea of how the innovation works in
a conversation with Ogar who is a graduate from UNICAL's
Electronic and Computer Technology department.
“The device has two wooden tank (the up and down tank) for
collection of water, a pen stock to control water out of the
upper tank to the turbine, the turbine that convert the potential
energy of water into mechanical energy that rotate the
alternator through the pulley system, the alternator that
generates power and lastly a riding machine injector pump
motor which pump back water from the down tank to the upper
tank and the process continues”.
"A bucket of water if emptied in the tank and water is allowed
to flow and hit, turn the turbine which rotate the alternator, then
electricity is generated which then energizes a small pumping
machine that pump back the water into the first tank then
process continues.
"The system carries two tanks, up and down tank. I decided not
to show everything here for technical reasons
“It operates without a repulsive force or zero back electromotive
force (emf). I invented it to be used for practical demonstration
on hydroelectricity.
"It generates up to 20 watt during operation but I stepped down
the power to power one blinking LED for demonstration and
technical reasons.
“The system generate up to 20 watt of power that Powers the
injector pump and some phones and it operates when the top
tank is filled with a bucket of water and it’s a continues
system.
"Although, not every part of the system is shown here for
technical reasons because it’s going to be a huge technology in
the nearest future.
"It shouldn’t be a surprise to any one that water contains both
potential and kinetic energy and the law energy that it can be
converted from one form to the other.
"On like mechanical generators, this device has two major
sections also, the turbine that does the conversion of the
potential energy of the River into motion serves as the
mechanical part of the device while the alternator which convert
this mechanical energy into electricity, is the electrical part of
the device.
“The river that carries both the kinetic and potential energy is
the fuel or the power house of the device.
"This is an era of renewable energy, can we join hands together
to really developed this local innovation to solve the problem of
power outage in Rural and Urban areas? And also to combat
the challenges of global warming?
"What about training of youths on hydroelectricity by
establishing renewable energy? Building training centers across
the country and also creating job opportunities. God bless
Nigeria”, explains Augustine Otuokwa Ogar, who earlier
developed a 200 Mega Watts mini Hydroelectric power plant
with a capability to generate electricity.
