How 'sea blindness' is costing Africa one trillion US dollars

Heard on 702's John Robbie Show: a conference taking place this week which brought together about 21 African countries looked at problems faced by the continent's marine economy. 38 countries in Africa share a coastline however 'sea blindness' - the inability to realise the potential benefits of the maritime sector - shows that there's reportedly over one trillion US dollars that could be made that isn't being made on the continent. African Maritime Security Researcher at the Institute for Security Studies (ISS), Timothy Walker:

It's hard to estimate right now because we are still gathering the data, but we are overcoming the 'sea blindness' that we've been dealing with for many years now. Estimates vary, but there are hundreds of billions and into the trillions now and the ocean economy is something we are going to desperately need in terms of producing African prosperity in the future. South Africa's maritime plan of the future through Operation Phakisa - part of the National Development Plan and that's looking at African ownership of ships and also building ships within Africa for trade. What's interesting is that South Africa, for all it's maritime dependency - 90% of our goods are traded by the sea - we don't have any ships flying the South African flag. Countries like Liberia that are much less developed have thousands of ships flying their flag at sea.

Plans for new cable car for Signal Hill, Cape Town

Heard on Cape Talk's Breakfast with Kieno Kammies: a report in the Cape Argus notes how the Table Mountain National Park (TMNP) is looking into proposals for building a cableway up Signal Hill with a stopover at the Lion Battery where the noon day gun is fired. City of Cape Town Mayor, Patricia de Lille says this proposal falls under the jurisdiction of Sanral and her office therefore cannot comment on the development:

There are different pieces of land there and the one piece belongs to Sanral and there, the City cannot say what they can do with it. There's two pieces of land - one of which is vacant earth, where squatting was happening and the other has an electricity depot. We will start public consultation now following a Council meeting last week about what we should do with those vacant pieces of land. At the moment, we've only got permission from Council to seek proposals from the public. On the Sanral land, they have apparently been seeking to build cable cars for many years, but they have not put in an application to the City for land use of their own land. So the public can engage the City over the City's pieces of land.

Has your car's side window shattered out of the blue?

Heard on 702's John Robbie Show: a follow up from Thursday calls and texts where drivers were noting car windscreens exploding out of the blue. What explains this phenomenon? MD of PG Glass, Malcolm Carew:

The side glass is one piece of glass - about 4 mm thick - and it's tempered and the tempering process creates a compression skin on that glass. It's five times the strength of normal glass, but the moment there is impact, that glass will shatter into very small pieces so you don't have shards that damage the occupants in the car. In very unusual circumstances, you have manufacturing defects with these parts. There are cases where you have damage but that damage may have not gone through the skin compression, so it sits there, but then you go through a pot hole or rough road or you have a change in temperature and then you have a burst.
