in the eye of the beholder



I have one of those widgets on my Google home page that provides "today's reason to drink". Not, you understand, because I particularly need a good reason to drink. In fact, a father who was a part time alcoholic (he was great between the binges) and a very frustrating new allergy to red wine have conspired to keep me sober. Instead, I see it as "today's reason to celebrate".

So, when I saw that today is National Biodiesel day - I assume in the US - I realised that this was a day that I should certainly celebrate.

Until ten days ago I wouldn't have given it a second glance, but that was before I paid a visit to the Sasol Advanced Fuels Laboratory (SAFL) at UCT and discovered that there is a world of unexpected beauty inside every engine.

In a rather nondescript building tucked behind the maintenance department on the UCT campus, researchers are testing Sasol fuels and discovering some amazing things. I expected rather dour and nurdy chemists, but what I found when I visited there was a world of excitement and wonder.

Would you have expected the head of a lab dedicated to testing fuel made from coal to have been so inspired by the beauty of one of his students' discoveries that he reproduced it in a piece of jewellery for his wife?

The labs are filled with engines, but on the walls are pictures of the most amazing colours, captured by high speed film. Sprays of multi-coloured energy bursting out in a stream of light.

Even the apparatus is beautiful. In one lab, a sapphire with a diameter of 10cm plays a vital part in the combustion bomb, a piece of apparatus designed to measure soot, temperature and composition of fuels in the instant when the fuel combusts.

“Sapphires have special thermal properties,” head of the lab, Prof Andy Yates, told me, adding that the stone itself has been the subject of intense contemplation by students with more than just their studies on their minds.

In the picture above is the world's fastest fuel compression machine, built by one of the SAFL students. It looks at what happens when a known air : fuel ratio is squeezed very suddenly. The machine stops a piston which is moving at up to 40km/hr twenty times faster than a blink.

“It reveals a lot about fuel,” Yates explains. “What happens is that it 'thinks' about burning, starts to burn, stops burning and then explodes. These timescales are crucial to extracting the maximum capacity out of fuels.”

From my perspective, the best of all, and the colour that so inspired Prof Yates, with its supreme beauty was the "mysterious blue" of the cool flame that burns in the fraction of a second before the fuel explodes.

I'll never look at an engine in quite the same way again.

If only more of the public new what was going on behind the scenes. I just read this and thought wow, we just hear about the hybrids and zero emission and do not realise that their are other projects that are also trying to reach a goal of zero emission with cleaner burning engines.
This makes one think of the entire green footprint.
Also reminds me of God's creation and beauty in everything around us.

Sure Leonie. What do you have in mind?

i've had a similar engine love experience down inside a ship. but this is even better because they're looking into alternative fuels. these are exciting times we live in and quite possibly, the upside of this global economic downturn will be alternative thinking that will push us away from oil dependence...now that would be beautiful.

Twenty years after I was born a Brooks, I became a Wilson in one of those happy-ever-after fantasies that didn't quite work out the way I had planned. But Wilson was a nice name, and eminently preferable to Brooks (which in Afrikaans means underpants or knickers and led to horrible teasing at school) and I quite enjoyed it. It was one of those anonymous names that everyone could spell and I liked the fact that it was totally normal at first look, but had a secret history. The great grandfather of the Mr Wilson I married had emigrated from somewhere near Moscow to the US and like so many others with unpronouncable or "difficult" names (I think it was Tobinofsky) he was given another one. One of the legends is that Wilson was chosen from the phone book, another is that he particularly admired a Wilson (couldn't have been Harold). So, for the next 25 years or so, I built my name and reputation as the journalist Lynne Wilson ... until I met and married my new happy-ever-a

Like faded flowers, thrown away: Steve Biko and the Boer women

Image
A Boer woman with her dead child, the last of her children to die, photographed by Emily Hobhouse The women are wonderful. They cry very little and never complain. The very magnitude of their sufferings, their indignities, loss and anxiety seems to lift them beyond tears… only when it cuts afresh at them through their children do their feelings flash out. Some people in town still assert that the Camp is a haven of bliss. I was at the camp to-day, and just in one little corner this is the sort of thing I found – The nurse, underfed and overworked, just sinking on to her bed, hardly able to hold herself up, after coping with some thirty typhoid and other patients, with only the untrained help of two Boer girls–cooking as well as nursing to do herself. Next tent, a six months’ baby gasping its life out on is mother’s knee. Two or three others drooping sick in that tent. Next, a girl of twenty-one lay dying on a stretcher. The father, a big, gentle Boer kneeling beside her; while,

mind the gap

I'm suffering from an excess of velleity. Velleity is volition at its weakest. It's a mere wish or inclination, without any accompanying effort. My velleity is fed by an overactive imagination... I can see in my mind's eye exactly what my dream garden looks like, for example. So when I am outside, I'm imagining a tree there, a shrub here, a winding path and a bank of flowers. so the lack of all those things and the lack of effort on my part to make them happen don't worry me so much. It certainly makes things easier when you are living with a very large garden during our excessively hot and dry summers. I'd write more... but what can I say? Velleity strikes again.
