In 2008, we did a presentation for the City on LED Streetlights and Active Roadstuds. Our light units ARE Darksky approved. To date, we have yet to have another meeting with anybody in the City. We have sent emails and proposals to the relevant "green" departments, trying to get them to buy-in. All we have received is a "thank you for your email, and it will be forwarded to the Minister". Despite having a one-on-one meeting with the ex-mayor at a roadshow, we still sitting in the dark!
Personally, many of these fatal accidents in the middle of the night, on those dark roads, could have been less severe with better illumination on those hot-spots.
The ROI would have been completed by now.

Well said!
I was told by somebody from the CoCT "relevant department" that they are not looking at LED technology, despite an article published on the 2010-05-12 saying something to the contrary, because is to expensive!
When the Kyoto Protocol was signed, LEd technology for street lighting was in its infancy.Today they have achieved a performance that far exceeds MV & HPS lamps & at a fraction of the electrical consumption.
So... how come the CoCT is replacing the MV for HPS lamps?!
Many studies have been conducted proving beyond any reasonable doubt, that the "white light" produced by LEDs is far superior than the "yellow light" from the HPS's; it helps with night traffic & peatonal visibility, improves security & creates a much pleasant lighting environment.
Very well, the cost of LED lamps still higher than the HPS's, but when calculation include not only energy savings between 50 & 75% & the much lower replacement costs & maintenance over the life expectancy of LEDs (about 50000 hours) the proposition still a very good solution.
The shortsightedness of such a short term solutions addressing only one element of the equation (electricity consumption) is not worth it of its investment. Africa must stop doing things like this!
"if you don't have money you must buy the best there is, because you can't afford to buy twice".
Surely the most positive "green" element of Cape Town is that virtually all its electricity comes from a nuclear plant that emits no CO2!

The public e-Waste Collection Drive is a great initative. It would be interesting to hear the experiences from yesterday's event.
We went to see 'If a Tree falls' yesterday and it was food for thought. The apparent reaction is that what Earth Liberation Front was doing; setting fire on companies properties to stop them as part of protecting the environment is totally out of line. But, what do you do when you have talked and talked, but no one seems to listen? What motivated the persons in ELF? The documentary interview several involved persons in the Earth Liberation Front, and also the ones chasing them. The film especially portraits Daniel McGowan who was a very central actor in ELF. How hard should you pay for something you did in the past?
Personally I don't agree with the approach of ELF, but the documentary is definitely worth a view!
To be honest I had not done much research on the film beforehand. All I knew was that the story was based on eco-terrorism and the question if the Environmental Liberation Front are environmentalists or eco-terrorists. The movie tells a story that it is difficult not to be affected of, even if you are in to environmentalism or not. Not only the line between an actionist and a terrorist makes the issues of the film interesting, but also the way the American legal system treat and punish their convicted terrorists. Go see the movie Sunday 26th, at 5.45.
