Eskom represents nine SA science boffins

This month nine of South Africa’s brightest young scientists represented the country at the Intel International Science and Engineering Fair (ISEF) in Los Angeles, California, USA.

The nine learners are top achievers handpicked by some of the country’s top industry judges and experts at the 36th annual Eskom Expo for Young Scientists International Science Fair (ISF) in October last year. Read more…

Eskom behind innovation

According to the South African power utility, the young scientists competed alongside more than 1,700 learners from over 70 countries and regions for over $4 million in awards.

These include scholarships, high-end laptops, 3 grand prizes of $50,000 and the top award of $75,000.

Time is set aside for the learners to experience the host city for various tours and activities. As with the Eskom Expo, a significant component of the programme at Intel ISEF is social, as learners interact with each other during mixers and ceremonies.

Throughout much of the week, various seminars are also held for students, mentors and teachers.

Below are details of the learners and their projects:

Name/s Province Project
Zamazimba Madi   (F)  and Jacqueline Janse van Rensburg (F) Gauteng The project aimed to show the impact of high pollution levels on bacterial diversity using three dams in the Gauteng
region as a testing ground. The results found that bacterial diversity in these is inversely proportional to pollution
levels which may lead to potentially pathogenic bacteria outcompeting more benign phylotypes (an environmental
DNA sequence or group of sequences).
Reinier Scherman (M) and  Berno Myburg (M) Gauteng The project aimed to address forklift manoeuvrability (in storage warehouses) through a modified drive system to
increase efficiency. A prototype drive system was developed that can not only turn on point (which is not possible
with conventional forklift drive systems) and has the capability to change the vehicle’s position while maintaining the
same orientation.
Farah  Shaik (F) KwaZulu- Natal The project aimed to show the decreasing efficacy of sunscreen and to develop a novel product that would indicate
this using the principle of photochromism. The application of this formulation may protect individuals from the harmful
consequences of excessive sun exposure by alerting them as the sunscreen wears off.
Katinka Wilkinson (F) Western Cape The project researched the different methods of energy storage that could be used to replace a battery. A flywheel
energy storage system utilising rotational kinetic energy was identified as the most promising candidate. The prototype
was found to have relatively high efficiency. Tests showed that the device could deliver more than 80% of the stored
kinetic energy into the resistor load.
Anika Meyer (F) Gauteng The project aimed to determine if the roots, seeds and pollen of cycads (commonly referred to as “living fossils”
because they date back to the age of dinosaurs) contain the neurotoxin methyl-amino-L-alanine (BMAA). Through a
series of tests and analyses, the investigation found the presence of this toxin in the coralloid roots, seeds and
especially the pollen of cycads may be very hazardous to our health if these are airborne inhaled over many years.
Bianka Reyneke (F) Free State The project sought to determine whether there is a link between the visual motor abilities of learners in pre-school
and school performance later at high school, specifically in subjects like mathematics and science. The results of the
study showed that the higher the perceptual motor abilities in learners at an earlier age, the higher the chance that
these learners would have less difficulty with maths and science later on in their school careers.
Lawrence John van Staden (M) KwaZulu- Natal The project aimed to determine if a viable home-made nano-based symmetric double layer supercapacitator (SDLS)
can drive an inductive load (motor) after a quick charge at a low voltage for a number of charge-discharge cycles.
According to the results, the tested SDLS could drive the motor longer than the charging time for several
charge-discharge cycles, proving the hypothesis correct.

Parthy Chetty, Executive Director of the Eskom Expo for Young Scientists, said: “To represent South Africa on the world stage is a tremendous honour and privilege and our nine young scientists are well-deserving of this honour because they were our exceptional achievers last year.

“Their projects were selected because of how internationally competitive they are, therefore there is no doubt in my mind that they will return home with top honours.”

Thava Govender, Eskom Group Executive: Transmission and Acting Group Executive Sustainability & Risk, said: “Eskom is a world class energy provider and is proud to be the driving force behind the Eskom Expo for young scientists, which provides this fantastic platform for budding young scientists to thrive.

“The international competitiveness of our country lies in the hands of young scientists and innovators like these delegates going to compete in Los Angeles, USA.” Read more…
