The door closed. My eyes opened.

My dreams were halted as I sat up. She was already outside my window, the midnight moonlight lit her skin and erasing my fingertips on her arms. I opened the window… cold truth blew in. It stung my heart. She was going.

“Seriously? After four months this is how you are going to leave?”

Silence.

She was trying to control her breathing, to keep it as flat as possible. She had a unique, annoying gift of being able to compose herself in such situations, especially when she knew it was needed.

She stared at me.

My heart was pounding against my chest. In anger. In desperation. It had settled on her, but clearly she wouldn’t let me get close to hers.

I felt the first tear roll down my cheek. I quickly wiped away the second one. She just stared…

She could have been looking at me, thinking of other things. With her you never knew. She turned.

“Wait, please wait. Did you ever love me?”

She stuck her tongue out and left.

And I knew that was it: we were over. Thinking back, I might have known for a while that it was coming. But still… being prepared for something doesn’t guarantee your heart won’t break when it actually happens.

I left the window open, slightly. My head was spinning and my heart was tearing.

I laid on what was supposed to be our bed and dug my head in a pillow in an attempt to block out reality. It was useless; warm liquid from my broken heart poured out through my eyes. All I could smell was her.

But what was I expecting? It could never work. We were two puzzle pieces from different sets. Two pieces that were never supposed to fit… We tried to force it, and it ended in pain.

She was such an odd person. She had this ‘forbidden love’ thing about her. Being hers was strange, I knew she wasn't mine but I still tumbled head over heels. Being with her was like cheating on a diet. Or texting when you’re supposed to study.

She had beautiful, wild eyes that had perhaps seen too much. She got high on other people’s vulnerability. When her arms locked around me, she wasn’t just holding me, she was searching for pain. Insecurity. She would pin me down and kiss my nose. When she felt my guard coming up, she would tickle me and my power would leave me and enter her. She always won.

Often we’d try to watch the stars. I could never concentrate, her beauty was fierce and demanded undivided attention. She couldn’t focus either. She looked at the stars, not for their beauty, but for adventure. She looked at them as a guide.

I felt her hot blood in her embrace, she had to move to keep cool. There was rarely a still moment. Always dancing. Always moving.

I guess that’s what attracted me to her. I made her my adventure. I wanted to see what she had seen. I told her I was happy where I was but in reality I wanted to go everywhere she went. Wherever the stars would take her.

My lips only met hers when she was drunk. Perhaps she didn’t want to remember showing a little bit of emotion, being a bit vulnerable in front of me. But even then she rarely shared her thoughts with me.

So her secrets are still with her, while she knows mine.

That wild girl, may I never hold her again. She said she didn’t like it. She wanted to feel liberated. And my arms didn’t offer her that.

The girl with a storm in her heart had started a fire in mine and left.

I look out the window, where she had been standing. I almost smiled. What was I thinking?  Thinking I could fix her? Whether I love her or hate her, it makes no difference because she’s not here. She’s not coming back.

I will never know what exactly she wanted with me. But I’ll grow wiser from this.

You can’t teach someone who’s power hungry to surrender. You can’t mould someone who despises being held. You can’t put out a wild fire. Don’t try to pick wild flowers, because their thorns will pierce your skin and then they will wither because of your blood. But their scent will linger forever.

Now I know. You can’t tame someone who is wild. You shouldn’t offer your heart to someone who has sold her soul to adventure.

Don’t try to love someone who can’t be still.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
