First Sesotho soundtrack for fulldome film launched at Naval Hill Planetarium

In December, the Naval Hill Planetarium used the voice of a well-known South African actress for yet another trailblazer: the first Sesotho soundtrack for a full-dome film.

“It is important for our children to become interested in science and astronomy through exposure to good language use in their mother tongue from an early age, so that we can still make a sound contribution to these fields in the future,” said Prof Matie Hoffman from the Department of Physics at the University of the Free State.

Space Shapes, a child-friendly fulldome film by the Ott Planetarium at the Weber State University in Utah in the US, was translated into Sesotho as Dibopeho tsa Sepakapakeng by Khantlapane Selina Ketla and Dr Andries Hoffman, following last year’s release of the short film by the Naval Hill Planetarium as Ruimtevorms in Afrikaans. The film, created by participants of the 2010 Blender Production Workshop in Utah, takes young audiences on a journey to explore the different shapes found in space.

The voice artist, Tshireletso Nkoane, a star in her own right, is best-known for her television roles in the drama series, Tshisa, the comedy series, Moferefere Lenyalong, as well as the miniseries, Naledi. She has several theatre and radio credits to her name, and also boasts a diploma in Electrical Engineering.

The premiere of this Sesotho trailblazer, as well as the CosmoQuest and Ward Beecher Planetarium’s English fulldome film, Cosmic Castaways, will take place at the Naval Hill Planetarium on Saturday 17 February 2018 at 17:30. Cosmic Castaways is an exciting work that reaches out to places where there are no constellations; where there are still isolated stars to be found in the voids between the galaxies.

Tickets for this double premiere, as well as for the weekly Saturday 17:30 shows, are available from Computicket – just search under ‘planetarium’ on the Computicket website or visit Checkers.

Lithium-ion batteries research set to improve ordinary lives

Dr Koao is making a much-needed contribution in improving lives of ordinary people through his research on lithium-ion batteries.

The future of relevant and top-notch scientific research at the Qwaqwa Campus is in good hands. Dr Lehlohonolo Koao is one of the five members of the Vice-Chancellor’s Prestige Scholars Programme (PSP) on the Qwaqwa Campus.

The need to improve the efficiency of heating mechanisms in his immediate community in Qwaqwa, and the support he receives from the PSP, have become catalysts for his current research project on lithium-ion batteries. According to Dr Koao, the study will focus on producing batteries that last longer, store more energy, are cheaper to manufacture, and are environmentally friendly when being disposed of. These are key factors in solar energy.

‘’The majority of households in my neighbourhood have benefited from the government’s project of providing households with solar panels to help with lighting, cooking, and heating without worrying about the ever-increasing electricity costs,’’ said Dr Koao.

‘’Since my arrival in the area, I have realized that the heat absorption rate of the batteries used by solar panels is not enough. As a result, these batteries also lack enough power to sustain the supply throughout the day, especially on a cloudy day,’’ he said.

His research project focuses on improving the efficiency of lithium-ion batteries that are now commonly used in portable electronics, such as cell phones and laptops. This kind of battery is rapidly replacing the usual lead-acid batteries. Dr Koao’s determination to contribute towards a safer and more efficient heating absorption system has made him move away completely from his PhD study on lighting material.

‘’My previous study was on reducing the power usage on domestic and industrial lights as they use more electricity. This study, on the other hand, will enhance power retention in the batteries for improved daily life since cell phones, solar panels, and laptops, to mention only a few, are now a way of life,’’ he added.

Dr Koao is a Senior Lecturer in the Department of Physics, where he specializes in solid state materials.
