Varsity showcases new products

MASERU – THE National University of Lesotho (NUL) yesterday held an expo as part of the Second Africa-EU Renewable Energy Research and Innovation Symposium. The symposium was held at ’Manthabiseng Convention Centre.
Among some of the displayed products was a special stove that is environmentally friendly. The stove, which uses firewood, emits very little smoke.
The stove’s designer, Lebohang Pheko, a former NUL students, told thepost that his stove, (paola in Sesotho), is a modified version of the stoves used in traditional Sesotho homes.

It uses solar energy. When the stove is fully charged it can charge phones and power a light bulb.
On the bottom part of the stove is a battery and a fan to help keep the battery cool.
The fan also helps to sustain fire without causing smoke which can be harmful to the climate.

“This stove uses any form of wood or dried cow dung. It also uses saw dust and planks particles for people who prefer not to cut wood to make fire and also those who want to save time,” Pheko said.
The designer also ensured that smoke does not filter downwards but goes up into the atmosphere.
Tšolo Phantši, who was at the symposium, is into nano technology.

He said nanotechnology is the science of making something very small.
Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers.
One nanometer is a billionth of a meter.

“An object the size of a pen can be crushed into small particles and its properties crushed so small that they can be used to kill cancer cells, which is very alarming nowadays,” Phantši said.
Phantši said the application used is heat energy. He said fossil fuel is getting finished because its demand is high while supply is very low.
Solar will be used to generate electricity using Nanotechnology.

“Cars will be able to use electricity with the help of Nanotechnology, smart phone lids can be water proofed by using small particles that use small resistors,” he said. Lastly, Khothatso Mqeqa produces wormwood tea.

He said wormwood is mostly used by the Chinese for medicinal purposes.
It can be used to disinfect cuts and can be used for curing colds, headaches, coughs, and fever.

“Wormwood can be used for minimising diabetes, high blood pressure, arthritis and swollen joints,” Mpeqa said.
“It builds the immune system as well,” he said.

“I aim to challenge all these sicknesses but already there are people who have testified that wormwood tea has helped them.”
Mpeqa also produces crashed vegetables such as green peppers, onions and other kinds of vegetables which are nutritious.

Since the vegetables are dried, they first need to be soaked in milk to increase quantity and they can be cooked later according to the user’s preference.
In addition, Mpeqa said his products’ shelve life is very long because they are dried. They can last at least two years.
