Snoopy action at a distance – quantum theory can help spot stealth planes

Researchers at the University of Waterloo are using the quantum principle of entanglement – memorably called “spooky action at a distance” by Albert Einstein – to develop a quantum radar that can expose stealth aircraft and missiles. Unjammable radar Traditional radar is vulnerable to interference from space weather events such as geomagnetic storms and solar…

Time to step up – Business confidence beyond Ramaphoria

Many would have predicted the surge in business confidence when Cyril Ramaphosa became president of South Africa in December. Just as predictable was the inevitable dip back down in May. Fair or not, it seems very similar to the hype cycle of technologies. When a promising technology like blockchain first enters the market, euphoria buoys…

Local airfields choose Tellumat for fully-compliant ground lighting with sophisticated monitoring and control

Market need Many small and mid-sized airports in southern Africa face a difficult migration from ageing airfield ground lighting (AGL) systems. Typically based on dated analogue technologies, such systems rely on manual controls across airports to switch lights on and off and offer no feedback facility, forcing airport personnel to physically check lights in all…

Africa’s most talented engineers

Keep your fingers crossed for South African engineers Collins Saguru and Shalton Mothwa! The pair have been shortlisted to receive the upcoming Africa Prize for Engineering Innovation in June 2018. Launched by the Royal Academy of Engineering in 2014, the award recognises engineering talent from across sub-Saharan Africa. This year, top innovations include the use…

Armed or not, this starfish robot just keeps coming

Japanese engineers have created the Pentabot, a robot inspired by a relative of the starfish called the “brittle star”, which has the unique ability to keep going even when it has lost most of its limbs. By copying the neurological and physical attributes of the brittle star (aka an “ophiuroid”), the Pentabot has successfully emulated…

Innovation borne of distress

“In the midst of every crisis lies great opportunity.” This quote, attributed to Albert Einstein, has the ring of truth: While no-one will knowingly walk into hardship, many who have seen it know never to “waste a good crisis” (as Winston Churchill is thought to have said). Recognising and filling a need borne of disaster…
