Young inventors showcase talent at 2016 NTA Children Expo
NAN-H-90
Expo

Abuja, Oct. 25, 2016 (NAN) Children from different schools all over the country displayed various inventions and talents in science and arts at the on-going Nigerian Television Authority (NTA) Children’s Expo in Abuja.
The theme of the 2016 edition of the Expo is “’Improved Technology as Impetus for Mechanised Agriculture, Renewable Energy and Power and the General development of Nigeria’’.
The News Agency of Nigeria (NAN) reports that schools from all states of the federation are represented by their students at the exhibition from which a winner will emerge.
Some of the participants who spoke to NAN said they were happy to be invited to the expo at which they could showcase their talents.
One of the students, Miss Edina Msurshima, a student of Vatyia College in Makurdi, who invented an Anaerobic Digester, said the digester could be used to generate light through a generator without fuel.
“’My work is on generation of electricity using Bio gas; bio gas is waste from animals and it is a mixture of gases such as mitten, carbon IV oxide and hydrogen sulphur.
“It also contains traces of gaseous elements such as ammonia, water vapour and the rest.
“The gas is generated from the action of microorganisms in an anaerobic digester; an anaerobic digester is a system that works without oxygen.”
Msurshima said that when the gas is built, carbon IV oxide and other gases hinder burning to generate the electricity.
According to her, the gas passes through a set of purifiers, the first one is sodium hydroxide and the second is iron and the silica gel.
“This helps to remove other impurities from the gas especially when it is channelled to the burner; the anaerobic digester generates light through a generator without fuel.”
On the benefit of the digester to society, she said: “’It can be used on poultry farms”.
The young inventor said that the waste becomes pathogen free and the materials can be converted to other products while the sludge can be used for manure.
“And it is also a cheaper way of generating electricity,” she said.
Messrs Joseph Orya and Ichor Joshua, representatives of Benue Innovators Academy, Makurdi, also invented a cellular irrigation system.
Joshua told NAN that a cellular irrigation system is a system that produces water through a process called Molasses using an activate carbon condenser they call ‘JJ condenser’ (Joseph and Joshua).
He said that the cellular system created by them has charcoal as the principal component.
“’The cellular system enables the farmer to supply water to his farm; that is the irrigation process. This can be done through cell phones.
“When the telephone number attached is dialled, it produces a musical sound from the cell phone in the control panel which is amplified through the amplifier circuit to activate and supply water to the farm.
“After this is done, a vegetronix censor, which is a moisture censor that measures the amount of waste in the farm, helps to stop the flow.
“The vegetronix, which is solar powered and can be used anywhere, automatically turns off the flow of water. It can also be manually operated.”
According to Joshua, the project is targeted towards agriculture and it aims to encourage dry season farming and water production.
He also said that “’it can ultimately boost the GDP through the exportation of cash crops and boost the supply of oxygen to animals”.
NAN reports that the 2016 NTA children’s Expo began on Oct. 23 and will end on Oct. 27. (NAN)
