Tesla leading the way to sustainability

SAM MUKWAMU

Global carbon dioxide emissions from motor vehicles have been a major contributor to climate change over recent decades, prompting a need to move to cleaner sources of energy to power vehicles.

Tesla has been one of the companies that has dedicated itself to moving towards electric powered vehicles. In 2014, Tesla announced their plans to construct a “Gigafactory” to produce the lithium-ion batteries required to power their proposed annual production of 500 000 cars. Tesla’s goal is to prompt the rest of the world to change to electric powered vehicles through the production of enough cars. By January of this year, Gigafactory 1 in Nevada, was about a third complete, and commenced with the production of their lithium-ion battery cells that are to be used in Tesla’s energy storage products and Model 3 cars. According to Tesla CEO, Elon Musk, the Gigafactory, which is predicted to be finished in 2020, will be able to produce more lithium-ion batteries in one year “than were produced worldwide in 2013”. The Gigafactory, which is being constructed with the help of a $1.6 billion investment from Panasonic Corp, “will also be powered by renewable energy sources, with the goal of achieving net zero energy”, claims Tesla. By the end of the year, Elon Musk is expected to announce plans for Tesla to build more Gigafactories outside of the USA, which won’t just be building battery cells but also full vehicles.

Technology for good: assistive technology and its benefits

GEMMA GATTICCHI

Technological advancements have become an essential part of the disabled community’s way of life. These improvements are far-reaching and include increasing mobility, inclusivity and general ease of life.

According to a community survey released by Statistics South Africa, the South African national disability prevalence was 7.7% in 2016. This includes over one and a half million people who experience some difficulty in hearing. Professor Swanepoel from UP’s Department of Speech-Language Pathology and Audiology, is part of the development of the ‘hearScope’ – a smartphone otoscope used for the diagnosis of ear disease. According to the HearX website, this development strives towards low-cost automated smartphone and cloud-based otitis media diagnosis. It is this kind of technology that could result in early intervention and help treat the onset of hearing problems in the future.

The science of sustainable food in South Africa

South Africa has a population of almost 56 million people and with a recent scourge of droughts in South Africa, feeding this many people can be difficult. However, according to Wandile Sihlobo, South African agricultural economist and columnist for Business Day and Farmer’s Weekly SA, South Africa’s maize yields have increased in production since 1919. In 1919 South Africa produced approximately 0.7 tonnes of maize per hectare, in 2010 almost five tonnes of maize per hectare were produced, and the amount produced is continuing to rise.

South Africa has a long history with Genetically Modified crops (GM) the first GM crops being planted in 1998. This came after the Genetically Modified Organisms (GMO) Act of 1997 came into effect. South Africa is now the 8th largest producer of GMOs in the world. The Public Understanding of Biotechnology, an initiative of the Department of Science and Technology, says that in 2012 to 2013 “86% of maize cultivated in South Africa is GM maize.”
