AECI eyes power generation

first_img5 March 2008South African chemicals, explosives and property company AECI has proposed a number of ways to tackle the country’s electricity shortage, including the possibility of generating power from coal or gas at its Modderfontein site outside Johannesburg.“A feasibility study for a co-generation plant, based on use of natural gas from Mozambique and located at Modderfontein in Gauteng, indicated that such a plant, producing about 25 megawatts of electricity and simultaneously producing enough process steam to meet the requirements of the Modderfontein operations, could be economically viable,” AECI spokesperson Fulvia Putero told SAinfo this week.“The capital investment required was estimated at about R200-million and the project would take about two years to implement.”Apart from securing the group’s own energy supply by generating electricity at the power station, fuelled by natural gas supplied by Sasol Gas, the company would be able to sell surplus electricity back to the national grid.However, Putero pointed that despite initial plans, Sasol Gas had informed them that sufficient natural gas might not be available for the project, meaning that AECI could not currently proceed with the planned tender to Eskom.The tender submission deadline for state company Eskom’s call for co-generation projects by leading industry players has since been extended to end-May 2008. Other companies that have recently expressed an interest in co-generation projects include agri-processing company Tongaat Hulett.“Alternative options, such as use of coal-based co-generation, are currently being assessed,” Putero pointed out.AECI chief executive Graham Edwards told Engineering News last week that the company was looking at a number of alternative options for fuel, including methane gas from a nearby landfill, which could also earn the company carbon creditsAnother option was to enter into an agreement with a coal mining company to secure coal supplies over the long term. The viability of such a plant required security of fuel supply over the long term, and at economical prices, Edwards told Engineering News.SAinfo reporter Want to use this article in your publication or on your website?See: Using SAinfo materiallast_img read more

Apple’s iPhone 5S Camera Shoots To Kill: Big Aperture, Burst Mode And More

The camera will feature a sensor that is 15% larger than that of its predecessor. When it comes to cameras, Apple gets image quality: improving sensor size and aperture is the real way to evolve a camera—not megapixels. Apple will also introduce auto image stabilization, which is a boon for those of us with not quite steady hands. And Apple claims that the speedy new A7 chip will yields autofocus that’s twice as fast.On the video side, the iPhone 5S can capture 720p HD at 120 frames per second. The new “slo-mo” feature can slow that footage down to a 120 frames-per-second crawl. While it’s no Phantom—the ultra high end video cameras famous for their slow motion skills—it’s a fun addition for anyone who shoots and shares video.The new iPhone camera features span both the hardware and software side of things, but the hardware is the real prize here, since we had a preview of the new photography software when iOS 7 was announced earlier this year. In iOS 7, mobile photogs can put the iPhone 5S’s hardware specs through their paces with some nifty new features. Beyond a flatter visual redesign to match the overall Ive-vibe, iOS 7 features an Instagram-inspired photo filters and even a mode to shoot square shots from the get-go. The totally overhauled iOS 7 camera app offers 15-zone autofocus matrix metering, “True Tone” flash for color correcting blown-out flash shots and a 10 frames-per-second burst mode, activated by holding down the shutter button. The iOS 7 camera can also take multiple images and choose the best of them or combine them for a better-balanced shot, similar to the idea of HDR or image bracketing. With the multiple image burst mode, the device actually decides which image it thinks is best—not unlike the “Highlights” feature in Google+, which picks your best image for you (and is often right).Won’t be gunning for the iPhone 5S in that delightful champagne gold? Don’t worry—the iPhone 4S, iPhone 5C and iPhone 5S will all share in the photography software upgrades baked into iOS 7.last_img read more
