In the following sections, we delve into some of these groundbreaking inventions, exploring their origins, their creators, and their current applications. Each invention tells a story of determination, creativity, and the relentless pursuit of progress. Together, they paint a picture of a continent that is not just consuming technology but is actively contributing to its development.

Power Barges

Power Barges, also known as floating power plants, were developed to provide electricity to remote areas. These self-contained, floating power plants operate independently of local resources or infrastructure, making them ideal for providing energy to coastal regions, harbors, or sites near rivers. They are a fast, effective way to deliver electricity where it’s needed most.

Armoured Vehicles

Africa, particularly South Africa, has a rich history in the production and supply of armoured vehicles to the rest of the world. These vehicles play a crucial role in military operations, serving either a direct combat role that incorporates a variety of weaponry, or a personnel carrier function that protects troops and delivers them to and from the battlefield.

The Rooikat

The Rooikat, created by South African defence major Denel, is an armoured reconnaissance vehicle with a primary attack function and fire support role. Recognisable by its Denel GT4 76mm high-velocity gun for anti-tank and fire support, the Rooikat can also be armed with two MG4 machine guns and eight smoke grenade dischargers for evasion purposes. To keep it moving over rough terrain, the 8×8 wheeled 28t Rooikat is powered by a 563bhp, ten-cylinder diesel engine. It is currently solely in use with the South African National Defence Force (SANDF), having been used in operations in the Lesotho intervention of 1998-9 and the Namibian War of Independence since it entered into service in 1989.

The Ratel

The Ratel, known as the first wheeled infantry fighting vehicle to enter military service worldwide, is currently in use with 13 militaries across Africa and the Middle East. The SANDF has more than 500 Ratels in its arsenal while the Jordanian Armed Forces own around 300 Ratels. Armaments differ depending on the variant, but Ratels can be fitted with a turret, anti-tank guided missiles, anti-aircraft platforms, mortar systems and machine guns.

These armoured vehicles, among others, showcase the innovative spirit and technological prowess of Africa in the field of military technology.

Dolosse

The Dolos, a complex geometric shape used around the world to protect harbor walls from the erosive force of ocean waves, was invented by South African Eric Merrifield. These massive, uniquely shaped concrete blocks have become a beacon of innovation in safeguarding harbor walls and coastal installations from the destructive power of ocean waves.

Penile Transplants

The world’s first successful penile transplant was carried out at Tygerberg Hospital in Bellville, Cape Town. This medical breakthrough has provided hope and improved the quality of life for many men who have suffered traumatic injuries.

Middle Ear Replacement

Professor Mashudu Tshifularo, a South African educator and Otolaryngologist, led the first team to use 3D-printed bones for reconstructive middle ear implants, providing a cure for some kinds of deafness. This groundbreaking achievement marked a significant milestone in medical history.

Using a 3D printer, Professor Tshifularo creates implants that replace the ossicles: the hammer (malleus), anvil (incus), and stirrup (stapes) during middle ear reconstructive surgery, or tympanoplasty. These 3D-printed bones are more affordable compared to the traditional titanium implants.

On 13 March 2019, Professor Tshifularo and his team at the Steve Biko Academic Hospital in Pretoria performed the first transplant. The endoscopic procedures lasted approximately 2 hours1. The first patient was a 40-year-old with accidental trauma damage and the other was a 62-year-old born with a middle ear issue and a history of failed interventions.

This pioneering achievement by Professor Tshifularo has opened up new possibilities in the field of Otorhinolaryngology. It has the potential to transform the lives of millions of people who suffer from hearing loss due to middle ear damage
