  • 2018 Sasol Solar Challenge will begin in September, end in Stellenbosch

    Get your sun hats, parasols and high-tech solar-powered vehicles ready. The latest edition Sasol Solar Challenge endurance event will kick off in September 2018. The competition's leaderboard is determined by total distance covered across a seven day period by vehicles powered by the sun's rays. The team with the most distance covered wins the title. And unlike traditional endurance racing, it's not the first team across the finish line who receives the plaudits. 15 teams from Australia, China, Japan, the Netherlands, the US and South Africa, will take part in the challenge, including two teams who have not competed in the...

  • London’s red buses to run on coffee waste

    London's iconic red buses will soon assimilate into the lives of Londoners by running, at least partially, on coffee. On Monday this week, a company called Bio-bean teamed up with oil giant Shell to introduce a small amount of oil extracted from coffee waste into the diesel and biofuel mixture already used by the buses. The company will produce 6000 litres of fuel a year -- less than 0.01% of the London buses' total use in 2015. But the city's authorities want to increase the number of buses fueled by a blend of diesel and biofuels. It's looking at using cooking oil waste, tallow (a form...

  • NASA, Uber are serious about bringing flying taxis to cities by 2023

    In an unlikely partnership, NASA has sought the services of Uber to build air control software that will manage the flying taxis of the future. Yes, flying taxis. The partnership, announced today at WebSummit in Lisbon, is not beyond Uber's personal ambitions either. In April 2017, the company announced plans to launch a flying taxi programme -- dubbed UberAIR -- in Dubai and Dallas by 2020. Now Los Angeles will also be added to the roster. Uber has also previously toyed with using helicopters in Cape Town in what was more a marketing stunt than feasible city transport solution, but the aircraft Uber...

  • Cape Town’s new buses will be all-electric come 2025

    Cape Town, along with 11 other major world cities, has vowed to shirk purchasing fossil fuel-powered buses in favour of electric models for its inner city transport networks by 2025. The cities, which include Auckland, Barcelona, Copenhagen, London, Paris, Los Angeles, Quito, Vancouver, Mexico City, Milan and Seattle, signed the agreement which is an extension of the already established C40 Clean Bus Declaration Act. C40 cities, of which Cape Town is a member, is an initiative that aims to reduce harmful emissions in city centres and promote green practices. The agreement also ensures that "major areas of the city" will be declared...

  • Mayor: Cape Town to source 20% of energy from renewables by 2020

    Cape Town mayor Patricia de Lille today took to Twitter in an hour-long update regarding key issues affecting the City of Cape Town, including the ongoing water crisis, the superblocking in Imizamo Yethu, and climate change. The speech itself was delivered at a city council meeting, but livetweeted from her account before the full speech was published Thursday afternoon. Cape Town's water crisis continues "Let me start with the water crisis and yes despite the recent rains, we are still in a drought," she began, shedding light on the City's plans to combat the low dam levels and drier-than-normal winter. She also lambasted...
