African Digital Laser Breakthrough Promises Future Innovation

For decades many African countries have experienced low investment in research and development (R&D) and scientific innovation. One of the few nations to benefit from a sophisticated university network and research and development sector was South Africa. It still ranks top on the continent for funding R&D and its high number of scientific journals.

And it seems this support has paid off in a recent innovation. The world’s first digital laser designed and built in Africa has been developed by a team of physicists at the University of KwaZulu–Natal in South Africa (http://www.ukzn.ac.za/), as reported in the MIT Technology Review (http://www.technologyreview.com/).

This innovation joins a positive trend in Africa, where support to science, technology and R&D is rising – albeit from a very low base. In 2010 UNESCO – the United Nations Educational, Scientific and Cultural Organization – found Africa was reversing decades of neglect in research and development. African countries were increasing investment in science and technology after realizing it will accelerate their connection with the global economy and help create better-quality jobs to tackle poverty. The UNESCO Science Report found Burkina Faso, Kenya, Nigeria and South Africa had adopted laws to support biotechnology research, for example.

Since 2005, six new science academies have been established in Mauritius, Morocco, Mozambique, Sudan, Tanzania and Zimbabwe. This compares to nine established between 1902 and 2004.

The proportion of GDP (gross domestic product) devoted to R&D averages 0.3 per cent in Africa, according to UNESCO.

South Africa continues to lead in R&D spending, raising its investment from 0.73 per cent of GDP in 2001 to 0.94 per cent in 2006. The country is home to 46 per cent of Africa’s scientific publications compared to 11.4 per cent in Nigeria and 6.6 per cent in Kenya (UNESCO).

Experts say the digital laser developed in South Africa is a breakthrough that will open up ever-further innovations and business opportunities.

So, what is a digital laser and what is the innovation? A laser is short form for Light Amplification by Stimulated Emission of Radiation. It is a device that produces a concentrated light source. Unlike conventional light sources that emit a diffused, multispectral light, lasers allow for a monochromatic light beam to be concentrated on a small area. This can be used to cut an object precisely, or beamed over long distances without losing its strength.

Lasers can create immense light, heat and power at close range and are regularly used in surgery and medical diagnosis.

Conventional lasers require external devices to alter and bend the laser light beam. The digital laser allows the shape of the beam to be digitally altered internally at the touch of a computer keyboard and gives greater immediate control. This means a plethora of new shapes can be formed with the laser beam, and this can have many practical applications.

The digital laser augers in a new age of creativity with lasers and more spontaneity in how they are used. Rather than having to place a lens or mirror at the front of the casing to shape the laser beam, this innovation makes it possible to create any shape desired digitally by a computer. The research team has been able to create various complex shapes for the laser beams in experiments. One mooted use is to apply laser beams to manipulate microscopic objects – similar to the tractor beams seen in science fiction films such as “Star Trek”.

Few of us spend much time thinking about lasers, yet they are ubiquitous in the modern world and are found in many electronic products (https://en.wikipedia.org/wiki/List_of_laser_applications). They play a critical part in the modern world’s economy. Some common applications for lasers include laser light shows at music concerts, bar code readers at the grocery store, or laser pointers used during public presentations. Dentists also use them to speed the hardening of fillings.

Not to exploit lasers as a technology in the modern world is equivalent to bypassing the silicon micro-chip that sits inside personal computers, electronic devices and mobile phones.

Bangladesh Coffin-Maker Offers an Ethical Ending

Few people want to think about death, and many are ill-prepared when it happens to a loved one or friend. But it will happen to us all – and growing ethical and environmental concerns are reshaping the way many deal with the inevitable event. More and more people are seeking a lower-cost option for being disposed of that also does not harm the environment.

There are many ideas out there, but one that is getting attention is using sustainably sourced and fairly traded coffins as a way of reducing carbon emissions resulting from a person’s death.

Bangladeshi pioneers Oasis Coffins (oasiscoffins.com) are crafting ecologically sound, Fair Trade coffins and generating jobs and income for an impoverished region of the country. The coffins are made from locally grown bamboo, seagrass and willow and are a clever piece of design.

Bamboo is as strong as steel and yet flexible, and the coffins made from it look like typical burial boxes – but can be folded back into their footprint to be stored flat. This is a great space-saving innovation and makes it easier to store the coffins and also to ship them to overseas markets. This clever design is reducing the amount of energy used.

Oasis has a manufacturing workshop employing 70 people in the Nilphamari district of Bangladesh (http://en.wikipedia.org/wiki/Nilphamari_District), about 400 kilometres north from the capital, Dhaka. The region is poor, but large quantities of bamboo grow in the area.

It is a region where employment is seasonal and erratic, making family life chaotic as parents constantly search for stable work. Oasis Coffins is located in the Uttara Export Processing Zone (http://www.epzbangladesh.org.bd/bepza.php?id=EPZ-U), run under the authority of the Bangladesh Export Processing Zones Authority (BEPZA), a government agency that aims to “promote, attract and facilitate foreign investment in the Export Processing Zones.”  Its sales office is based in Birmingham in the United Kingdom.

The company began in 2006 with the idea of creating high-quality products using local materials while creating good quality jobs to achieve a double impact: changed lives and a protected environment. The hope is to create a business model that can be replicated elsewhere.

The company is structured to include both its product development and manufacturing in rural Bangladesh. It took its time conducting market research and product development to make sure it had a product people were willing to buy.

“We make beautiful, high quality products in an environment that gives people reliable employment and good working conditions,” said managing director David How on the company’s website. “Our products are in demand from people who are becoming increasingly conscious of their impact on the environment and others.

“It is encouraging to know that in bereavement, we can give life into people and a community in Bangladesh. We want people to know where their products are coming from, and to know that what they buy can benefit people elsewhere.”

According to its website, Oasis Coffins abides by the standards prescribed by the World Fair Trade Organization (wfto.com) and the European Fair Trade Association (http://www.european-fair-trade-association.org/) and is also a member of ECOTA (ecotaftf.org). The ECOTA Fair Trade Forum started in 1990 and is a networking and coordinating body for small and medium sized Fair Trade Enterprises of Bangladesh.

Employees are divided equally between women and men, and many have never been to school. They are paid 30 per cent more than the recommended rate for garment workers in Bangladesh.

Oasis Coffins know by name the farmers who provide the bamboo and all of it is harvested within 20 kilometres of the manufacturing workshop. Oasis Coffins also takes pride in the construction of the workshop, which features plenty of natural light, good ventilation and easy access in and out. A comfortable workshop is important for the health and happiness of manufacturing workers.

Employees receive a pension scheme, paid holidays, sick leave and a lump-sum payment if they leave. There is also a doctor available during working hours for free medical advice.

To help upgrade the skills of the workers, there are lunchtime literacy classes, and employees are also taught how to manufacture products to a high global standard.

The Oasis coffins are benefiting from the growing marketplace for green funerals in Europe and North America.

In Britain, ecological funerals are on the rise as people seek an affordable and environmentally sound way to be dispatched. The UK’s Co-operative Funeral Care, part of the Co-operative Group, is selling the Bangladeshi coffins at more than 900 of its funeral homes in the United Kingdom as part of its ethical strategy.

Providing funeral services can be an effective income generator. In Ghana, craftsmen have developed a global reputation for their quirky coffin designs celebrating the lives of the deceased. Ghana is also pioneering the selling of funeral insurance through mobile phones. Bereavement services are among the many basic needs of all communities, no matter where they are located. Just as people will always be born and get sick, they will also eventually die. Providing services that offer dignity to the families and the deceased can be a boost to local economies.

Thai Organic Supermarkets Seek to Improve Health

A Thai business is working hard to expand access to organic food in the country. It sees this as part of a wider campaign to improve health in the country – and its success has caught the attention of the government, which wants to turn Thailand into a global health destination.

The Lemon Farm chain run by Suwanna Langnamsank (http://www.lemonfarm.com/lmf/) was started 13 years ago and has grown to nine organic supermarkets in the capital, Bangkok. Lemon Farm works with 200 organic farms in Thailand and employs 160 people.

Organic food (http://en.wikipedia.org/wiki/Organic_food) – grown without chemicals and artificial fertilizers and not irradiated or subjected to other tampering – is believed by many to be healthier because it avoids the harmful effects of accumulating chemicals. It is also thought to be richer in vitamins and minerals because of the use of non-chemical fertilizers on the soil.

Lemon Farm sells made-in-Thailand organic vegetables and fruit, natural gift sets, soap and tea. There are also macrobiotic cafes in the supermarkets called Be Organic.  A macrobiotic diet avoids foods containing toxins (http://www.cancerresearchuk.org/cancer-help/about-cancer/treatment/complementary-alternative/therapies/macrobiotic-diet).

The supermarkets use eye-pleasing modern design to set themselves apart from more conventional supermarkets.

According to Lemon Farm’s website, it is a social enterprise and practices fair trade. It is using market-driven solutions to increase the availability of healthy food in the country. It seeks to support small-scale farmers and champion change in farming methods, encouraging a move away from dependence on harmful chemicals that damage human health and the environment and promoting “agricultural and economic self-sufficiency”.

The macrobiotic restaurant operates to six values, among them using fresh vegetables and only using produce from associated farms. The restaurants do not use added sugar, they cook using a pressure cooker, and use natural ingredients such as sea salt, ginger, fermented soy sauce and natural miso. They do not use any artificial preservatives or flavour enhancers such as monosodium glutamate (MSG), a common practice in Asian cooking.

Lemon Farm’s success as an organic food pioneer has caught the attention of the Thai government. The Ministry of Commerce (http://www2.moc.go.th/main.php?filename=index_design4_en) has contracted Lemon Farm to join its campaign to offer organic food in schools and hospitals.

By promoting organic food, the government is hoping to boost farmers’ incomes while improving health in the country and bolstering the country’s thriving medical services industry serving foreign patients.

“We need to promote healthy food and a healthy environment,” Piramol Charoenpao, deputy permanent secretary at the Ministry of Commerce, told Monocle magazine. “Thailand is a medical hub. The idea is to have retreat-style hospitals serving organic food. We’re increasing organic food production and educating people about it.”

Thailand has already built a good reputation with its medical and health services. More than 1.6 million non-Thais are treated in Thai hospitals annually, with an estimated 500,000 travelling specifically for medical treatment (The Guardian).

Former Thai Prime Minister Thaksin Shinawatra mooted the idea of making the country an international leader in medical tourism in 2003. It is expected providing medical services to overseas patients will make the country US $3.3 billion by 2015 (The Guardian).
 
It is hoped that offering organic food in hospitals and health facilities will boost the attractiveness and effectiveness of using health services in Thailand.

Medical tourism is considered one of the fastest-growing sectors in the world. Estimates place it as a market worth US $100 billion. Three countries that compete in this market by offering medical services in the English language include India, Singapore and Thailand. They compete by offering services comparable to wealthier countries but at considerably less cost.

Lemon Farm says it is on a mission to develop the marketplace for organic food in Thailand by educating consumers and producing “innovative natural food”.  It looks like it has already made a big impact.

Chinese Building Solution for Rapidly Urbanizing Global South

The global South is currently experiencing the biggest surge in urban population ever seen in human history. This transformation from urban to rural is happening in many different ways across the global South. Some countries have highly detailed plans and are building new cities from scratch, while other countries feel overwhelmed by their booming urban populations.

By 2025, it is estimated the developing world could become home to 37 megacities with more than 10 million residents (http://en.wikipedia.org/wiki/Megacity) (The Guardian). Sixty years ago there were just two megacities: New York and Tokyo. Today, there are between 21 and 23, and the UN is forecasting that by 2025 Asia will have nine new megacities. By 2025, the majority of the world’s megacities will be in the global South.

But how will these cities be built? How will they use resources well and ensure the rapidly rising new buildings are safe and healthy?

A Chinese innovator and Internet sensation has developed a way to rapidly build high-density, high-rise structures that are also safe and meet strict earthquake-proofing standards. Building upwards is an efficient way to get more use out of space and to free up land for things like parks.

Just as the first megacities such as New York began building skyscrapers a century ago, going upwards will be the solution many of the new megacities will choose as they feel the pressing twin demands of rising populations and financial restraints.

Based in Changsha, China (http://en.wikipedia.org/wiki/Changsha), the BROAD Group
(http://www.broad.com/) (http://www.broad.com:8089/english/) has become an Internet sensation for posting videos of it rapidly building skyscrapers. It does this to show off its innovative technologies, which have significantly reduced the time it takes to build high-rise buildings.

The BROAD Group calls itself “an enterprise based on the vision of unique technologies and the philosophy of preserving life.”

The company is a pioneer in making non-electric air conditioning equipment, energy systems, and sustainable building technology.

The company has come a long way since it was started in 1988 with just US $3,000. By 1995, it had shed its debts and loans. It sees its mission as confronting the two major crises facing the world today: atmospheric pollution and global warming. The company hopes to evolve into a social enterprise.

BROAD calls itself a world leader in making central air conditioning powered by natural gas and waste heat (http://en.wikipedia.org/wiki/Broad_Group). The company is currently exporting its systems to more than 60 countries and was an official supplier to the 2010 Shanghai Expo.

BROAD has recently been expanding its product range and moving into constructing sustainable buildings. In particular it is developing an expertise in rapid construction techniques. This is important in the modern world as cities across the global South experience population growth and the pressing need to house people and create workplaces efficiently. BROAD is proud of the 15-storey hotel in Dongting Lake in Hunan Province it built in just six days, which became a hit on YouTube (http://www.youtube.com/watch?v=sjGhHl-W8Wg). After this achievement, BROAD constructed a 30-storey hotel in 15 days.

Part of the BROAD Group, Broad Sustainable Building (BSB) claims to make the “World’s first factory-made building.” BROAD says its buildings are sustainable because they efficiently use recycled construction materials, rely on materials free of formaldehyde, lead, radiation and asbestos and avoid “construction sewage” dust or waste.

BROAD was provoked into making sustainable buildings after the Wenchuan Earthquake in 2008 (http://quake.mit.edu/~changli/wenchuan.html). A year after the earthquake, 300 researchers from BROAD developed an earthquake-resistant building technology.

The factory-made building works like this: a “main board” is prepared with a floor and ceiling, ventilation, water supply and drainage, electricity and lighting. This is then placed on a truck and taken to the building site. All the workers need to do on site is assemble the building by screwing in the bolts and finishing it with the painting and other decorating. This makes the time spent assembling the building on site, according to BROAD, just 7 per cent of the total construction hours. This means 93 per cent of the building is prefabricated in a factory compared to an industry norm of 40 per cent.

BROAD’s latest project and biggest challenge is to build Sky City One (http://skycityone.wordpress.com/) – the world’s tallest tower at 220 floors and 838 metres – in Changsha in just 90 days. A mix of residential, commercial and retail space, it will allow between 70,000 and 120,000 people to work and live. The start date could be November 2012 and the building completed by early 2013.

The finished building will be 10 metres taller than the current tallest tower, the Burj Khalifa (http://www.burjkhalifa.ae/) in Dubai.

Egyptian Youth Turns Plastic Waste into Fuel

The challenge of finding alternate fuel sources is capturing the imagination of innovators across the global South. As the world’s population increases – it recently reached 7 billion (UN) – and the number of people seeking a better life grows in turn, the energy demands on the planet are pushing up competition for existing conventional fuel sources.

The modern lifestyle that many aspire to requires energy, whether it’s using electronic products which consume large quantities of electricity, driving personal vehicles or living in homes that are artificially heated and cooled.

This energy hunger has opened up a whole new market demand that needs to be met. The scale of this market is enormous, but the solutions are ultimately limited only by people’s imaginations. An award-winning Egyptian teenage scientist is capturing attention for the imaginative solution of turning waste plastic into biofuel, sparking interest in the creation of a whole new source of wealth for her country.

Sixteen-year-old Azza Abdel Hamid Faiad (http://tinyurl.com/dysemjg) has found a new way to take waste plastic and break it down into fuel. She has discovered aluminosilicate minerals (http://en.wikipedia.org/wiki/Aluminosilicate) – which contain aluminium, silicon and oxygen and are found in clays – can break down the polymers that make up plastic (http://en.wikipedia.org/wiki/Polymer) to produce the gases methane, propane and ethane, all of which can be turned into ethanol (http://en.wikipedia.org/wiki/Ethanol), which is useful as a biofuel.

According to Inhabitat (inhabitat.com), a website dedicated to “green design, innovation, and the future of clean technology,” her solution could turn the country’s annual consumption of 1 million tonnes of plastic into a year’s supply of biofuel worth US $78 million.

Clever innovators are sitting on a goldmine if they can come up with renewable energy solutions. The U.S. Army alone is looking to spend US $7 billion on renewable energy sources and is accepting bids from the private sector to meet its needs (http://www.forbes.com/sites/toddwoody/2012/08/08/u-s-army-opens-bids-to-buy-7-billionin-renewable-energy/). The army is looking to sign contracts stretching up to 30 years for buying electricity generated by solar, wind, geothermal and biomass projects.

The options are numerous for renewable energy – from solar power to wind power to algae as a source of biofuels (http://en.wikipedia.org/wiki/Biofuel). The challenge is to find a fuel source that is plentiful, renewable, and crucially, doesn’t harm other needs.

Using biofuel as a replacement for conventional petroleum-based fuels like gasoline and diesel appears to be an attractive solution, but it can lead to other problems. Some people are using used cooking oils to convert into biodiesels, but sometimes there is not enough used cooking oil to meet demand. In short, a constant supply source is required to meet ever-increasing energy demand.

A famous example of where the use of renewable plant-based fuel sources can go wrong is the case of corn. The widespread use of corn as a source for biofuels – rather than for animal feed or human food – has led to accusations this is contributing to the global food crisis. The current drought in the United States is damaging corn crops and only making this problem more acute. The U.S. is the world’s largest producer of corn (US Department of Agriculture) and much of it is used as livestock feed around the world.

Faiad’s solution is appealing because the fuel does not come from biomass – derived from plant matter – but turns waste plastic into the raw material for biofuel.

Plastic waste is a common byproduct of modern life. Plastic is used extensively in packaging, bottles, bags and electronic products. It fills up landfill sites and is a blight on the landscape in many countries. It is also a product made from petrochemicals (http://en.wikipedia.org/wiki/Plastic), the very source of conventional fuel used by most of the world’s vehicles.

Breaking down waste plastic from bottles, packaging and other products into what is called ‘biofuel feedstock’ – the substance necessary to start the creation of biofuel – requires a means to turn the plastic into fuel.

According to Green Prophet (greenprophet.com), Faiad believes her technological breakthrough “can provide an economically efficient method for production of hydrocarbon fuel namely: cracked naphtha (http://en.wikipedia.org/wiki/Petroleum_naphtha) of about 40,000 tons per year and hydrocarbon gases of about 138,000 tons per year equivalent to US $78 million.”

This could be a big economic boost to Egypt’s economy, simultaneously reducing dependence on petroleum-based fuels and creating a new source of income. Egypt’s economy has been hit hard since the start of the Arab Spring (http://en.wikipedia.org/wiki/Arab_Spring). The number of tourists fell 33 per cent in 2011 and revenue dropped by US $3.7 billion from 2010 (Egyptian Tourism Minister). In 2009 about 12.5 million tourists visited Egypt, bringing revenue of US $10.8 billion. The tourism sector is one of the country’s top sources of foreign revenue, accounting for more than 11 per cent of GDP, and offers jobs in a country beset by high unemployment – for Egypt, tourism makes up 11 per cent of its GDP (gross domestic product) (Reuters).

Faiad’s innovation has not gone unnoticed. She received the European Fusion Development Agreement award (http://www.efda.org/) at the 2011 23rd European Union Contest for Young Scientists (http://ec.europa.eu/research/youngscientists/index_en.cfm). She is also receiving interest from the Egyptian Petroleum Research Institute (http://www.epri.sci.eg/), according to Inhabitat.

Ambitious Faiad is also seeking to take ownership of her innovation by getting a patent from the Egyptian Patent Office (http://www.egypo.gov.eg/english/default.htm).
