Money In The Wind

The South African government has presented the challenge for industry to find cost-effective renewable power sources. The answer may just be blowing in the wind.




Silas Zimu, one of the key players in South Africa’s fast-expanding renewable energy sector, says the seminal climate change documentary by Al Gore, An Inconvenient Truth, was the trigger for his new focus, the development of green energy in Africa.

Zimu, 46, took up the position of chief executive officer of the South African unit of Indian wind power company, Suzlon Energy in 2010, after years working for power utilities that relied almost entirely on coal.

“It changed my outlook so much I started searching for green solutions,” he says.

After running City Power Johannesburg, a parastatal electricity distribution company, for three years, Zimu came to Suzlon with 19 years’ of experience in South Africa’s power industry, including senior roles at the country’s power monopoly, Eskom.

He has now played a part in securing two of the government’s wind power contracts, which will involve billions of rands of investments.

Under his stewardship, the group, one of the world’s leading wind turbine makers, has already started building 66 wind turbines near Cookhouse in South Africa’s Eastern Cape province. When the units are completed by 2016 it intends to sell power through Eskom’s national grid by 2016. It is the biggest renewable tender awarded in the first round of government tenders.

Suzlon will operate and maintain the turbines energy project selected during round one of the government’s Department of Energy’s Renewable Energy Independent Power Producers Procurement Programme (REIPPP). The awarding of tenders through the program has been a long time coming, with the policy amended at least once, leaving potential investors somewhat confused for a time.

The Cookhouse Wind Farm is being developed in partnership with African Clean Energy Developments (ACED), described as a South African-based renewable energy project developer, owned jointly by Old Mutual-owned African Infrastructure Investment Managers AFPOC Limited.

Fulfilling government’s desire that South Africa, in terms of job creation and the local communities, benefits from the renewable tenders, the Cookhouse Wind Farm Community Trust holds 25% equity in the project. It is anticipated that the local communities of Cookhouse, Bedford and Somerset East will be beneficiaries of the trust.

“The strategy is to make Suzlon a company that embraces empowerment in South Africa, to manufacture in the country and have offices here. We have a locally-appointed team. We know the playing field and know what we should be aiming for, while understanding government’s renewable framework. The last few years have been tough, but this is the risk one had to take,” says Zimu.

This partnership was part of the awarding of the first government tender. Under the REIPPP, government has said it wants 1,850 megwatts (MW) to be provided by a variety of renewable power sources annualy; this includes wind, solar and power generated from biomass. It hopes to have this much on line by 2021, adding to the country’s current installed capacity of about 40,000 MW.

When Suzlon SA won its first tender, Zimu says friends and family threw a surprise party for him, but he says,

“I would like to celebrate when the first megawatt is generated”.

Zimu, who has a Master’s in engineering, has a 20% stake in Suzlon’s South African unit. It is part of Suzlon Energy, which is the world’s fifth biggest vertically integrated wind turbine maker. He sits on the executive committee of the global group, which is based in Pune, India.

The first project will import the turbines and steel towers to assemble the windmills but Suzlon energy SA is planning to form an operations and maintenance company that will be South African-based.

The intention is to build the steel towers in South Africa for a second project. Zimu says the group has already been awarded a second contract. It will be announced in the next few months.

“We are working towards financial close on that.”

South Africa plans three rounds of bidding for renewable energy projects in the second round Suzlon again secured the biggest allocation in terms of power it will produce. The two projects combined, when up and running, will make Suzlon the second biggest wind turbine company in the country.

South Africa’s desire to build up its green energy sector to reduce its reliance on coal, head off potential power shortages, and meet ambitious targets for slashing greenhouse gas emissions is attracting assistance from other countries. Zimu expects companies like Suzlon to benefit.

In March, Denmark said it would work with the South African government towards its meeting of its renewable goals. The Danish government said in a statement that before the transition from coal to wind energy can take place, wind resources must be mapped and the power grid regulated to allow wind energy to be exploited to the fullest possible extent.

“If we can assist a country like South Africa to convert to more renewable, energy efficient power sources, the climate as a whole will benefit. In 2009, South Africa’s carbon dioxide emissions constituted half of Africa’s total emissions,” says Martin Lidegaard, the Danish minister for climate, energy and building.

Currently South Africa boasts some of the world’s biggest coal-fired power plants and generates some energy from nuclear, natural gas and hydropower sources. While crippling power outages in 2008 forced Eskom to press ahead with two major coal projects, the country’s aim is to spread its power generation across a number of technologies to take advantage of the nation’s abundant wind and solar power potential. Ambitious solar, wave power, hydro and biomass initiatives are also being considered.

Zimu says that Eskom has the capacity to make all the grid connections and the Danish government may help government develop a policy on grid codes.

Zimu is leading Suzlon’s charge into other African countries.

“We have been awarded work in Mauritius and are interested in tenders in Kenya and Namibia,” he says.

It also presented submissions for work in Madagascar and has been invited to visit interested parties in Nigeria, Angola and Ghana.

“I think South Africa is showing other African states the way,” says Zimu.

Even so, other African countries such as Morocco and Kenya are developing ambitious projects of their own. In Kenya the $800 million Lake Turkana Wind Power project is billed as the continent’s biggest and is expected to generate 300MW of electricity.

However, GDF Suez of French and Moroccan company Nareva Holding plan to build a plant of the same size in the desert region of the North African country. Morocco is planning to have 2,000MW of installed wind power by 2020. Lesotho, the mountainous country landlocked by in South Africa, has its own ambitious.

On whether the costs of wind power compare favorably to those of other renewables, Zimu pointed out that solar is more expensive and says wind energy can compete with projects powered by biofuels.

“My vision is to go green, generate green energy [and] create green jobs”.

How Virtual Therapy Apps Are Trying To Disrupt The Mental Health Industry





Millions of Americans deal with mental illness each year, and more than half of them go untreated. As the mental health industry has grown in recent years, so has the number of tech startups offering virtual therapy, which range from online and app-based chatbots to video therapy sessions and messaging. 

Still a nascent industry, with most startups in the early seed-stage funding round, these companies say they aim to increase access to qualified mental health care providers and reduce the social stigma that comes with seeking help. 

While the efficacy of virtual therapy, compared with traditional in-person therapy, is still being hotly debated, its popularity is undeniable. Its most recognizable pioneers, BetterHelp and TalkSpace, have enrolled nearly 700,000 and more than 1 million users respectively. And investors are taking notice.

Funding for mental health tech startups has boomed in the past few years, jumping from roughly $100 million in 2014 to more than $500 million in 2018, according to Pitchbook. In May of this year, the subscription-based online therapy platform Talkspace raised an additional $50 million, bringing its total funding to just under $110 million since its 2012 inception.

The ubiquity of smartphones, coupled with the lessening of the stigma associated with mental health treatment have played a large role in the growing demand for virtual therapy. Of the various services offered on the Talkspace platform, “clients by far want asynchronous text messaging,” says Neil Leibowitz, the company’s chief medical officer.

Users seem to prefer back-and-forth messaging that isn’t restricted to a narrow window of time over face-to-face interactions. At BetterHelp, founder Alon Matas notes that older users are more likely to go for phone and video therapy sessions, whereas younger users favor text messaging.

“Each generation is getting progressively more mobile-native,” says John Prendergass, an associate director at Ben Franklin Technology Partners’ healthcare investment group, “so I think we’re going to see people become increasingly more accustomed, or predisposed, to a higher level of comfort in seeking care online.”

The ease and convenience of virtual therapy is another draw, particularly for busy people or those who live in rural areas with limited access to therapy and a range of care options.

Alison Darcy, founder and CEO of Woebot, a free automated chatbot that uses artificial intelligence to provide therapeutic services without the direct involvement of humans, says that with Woebot and other similar services, there is no need to schedule appointments weeks in advance and users can receive real-time coaching at the moment they need it, unlike traditional therapy. The sense of anonymity online can also lead to more openness and transparency and attracts people who normally wouldn’t seek therapy.

Along with stigma, the cost of therapy has historically acted as a barrier to accessing quality mental-health care. Health insurance is often unlikely to cover therapy sessions. In most cities, sessions run about $75 to $150 each, and can go as high as $200 or more in places like New York City. Web therapists don’t have to bear the expense of brick-and-mortar offices, filing paperwork or marketing their services, and these savings can be passed on to clients. 

BetterHelp offers a $200-a-month membership that includes weekly live sessions with a therapist and unlimited messaging in between, while Talkspace’s cheapest monthly subscription at $260-a-month, offers unlimited text, video and audio messaging.

But virtual therapy, particularly text-based therapy, is not suitable for everyone. Nor is it likely to make traditional therapy obsolete. “Online therapy isn’t good for people who have severe mental and relational health issues, or any kind of psychosis, deep depression or violence,” says Christiana Awosan, a licensed marriage and family therapist. 

At her New York and New Jersey offices, she works predominantly with black clients, a population that she says prefers face-to-face meetings. “This community is wary of mental health in general because of structural discrimination,” Awosan says. “They pay attention to nonverbal cues and so they need to first build trust in-person.”  

Virtual therapy apps can still be beneficial for people with low-level anxiety, stress or insomnia, and they can also help users become aware of harmful behaviors and obtain a higher sense of well-being. 

Sean Luo, a psychiatrist whose consultancy work focuses on machine learning techniques in mental health technology, says: “This why some of these companies are getting very high valuations. There are a lot of commercialization possibilities.” He adds that from a mental health treatment perspective, a virtual therapy app “isn’t going to solve your problems, because people who are truly ill will by definition require a lot more.”

Relying on digital therapy platforms might also provide a false sense of security for users who actually need more serious mental-health care, and many of these apps are ill-equipped to deal with emergencies like suicide, drug overdoses or the medical consequences of psychiatric illness. “The level of intervention simply isn’t strong enough,” says Luo, “and so these aspects still need to be evaluated by a trained professional.

AI 50 Founders Say This Is What People Get Wrong About Artificial Intelligence





Forbes’ new list of promising artificial intelligence companies highlights how the technology is creating real value across industries like transportation, healthcare, HR, insurance and finance.

Naturally, the founders of the honoree companies are excited about the technology’s benefits and, in their roles, spend a lot of time thinking and talking about its strengths and limitations. Here’s what they think people get wrong about artificial intelligence.

Affectiva CEO Rana el Kaliouby says she’s too often encountered the idea that AI is “evil.”

“AI—like any technology in history—is neutral,” she says. “It’s what we do with it that counts, so it’s our responsibility, as an AI ecosystem, to drive it in the right direction.” 

Companies need to be aware of how AI could widen bounds of inequality, she adds: “Any AI that is designed to interact with humans—Affectiva’s included—must be evaluated with regards to the ethical and privacy implications of these technologies.”

Sarjoun Skaff, CTO and cofounder of Bossa Nova Robotics, says that the biggest misconception he encounters is that artificial intelligence is actually, well, intelligent. 

“The truth is much more mundane,” he says. “AI is a very good pattern-matching tool. To make it work well, though, scientists need to understand the details of how it internally works and not treat it as an ‘intelligent’ black box. At the end of the day, making good use of great pattern matching still belongs to humans.”

Similarly, Aira cofounder Suman Kanuganti says that the public has “over-inflated expectations” for artificial intelligence.

“Garry Kasparov sums it up nicely: ‘We are in the beginning of MS-DOS and people think we are Windows 10,’” Kanuganti says. “AI realistically is still like a 3-year-old child at this stage. When it works, it feels magical. It does some things well, but there’s still a long way to go.”

So, no, we are nowhere close to “artificial general intelligence,” or AGI, where machines are actually as smart as humans.

“We’re still a long way from AI having the general intelligence of even a flea,” says David Gausebeck.

Despite the tendency to overestimate what artificial intelligence can do, the difficulty of building an effective system is often underestimated, some founders say.

“The systems you need to implement and manage machine learning in production are often much more complex than the algorithms themselves,” says Algorithmia CEO Diego Oppenheimer. “You can’t throw models at a complex business problem and expect returned value. You need to build an ecosystem to manage those models and connect their intelligence to your applications.” 

Put another way, you can’t just “sprinkle on some artificial intelligence like a magic sauce,” says Feedzai CEO Nuno Sebastiao.

One of the most common tropes that a handful of founders brought up was the idea that artificial intelligence is primarily a job killer. founder Oleg Rogynskyy says that AI should be seen as a creator of new opportunities instead of a destroyer of jobs.

“In a nutshell, AI does two things: It automates repetitive low-value-add work for humans (which will indeed take low-complexity jobs away), which we think of as ‘Autopilot,’  and it guides people on how to do their work or other activities better (which makes humans more effective at what they do), which we call ‘Copilot,’” he says. “While Autopilot can take simple, repetitive and boring jobs away, Copilot is absolutely the best way to guide, train and educate humans on how to do new things.”

‘AI Is A Powerful Tool’



Research forecasts that by 2025, machines will perform more current work tasks than humans. Murat Sonmez, member of the managing board, and Head of the Centre for the WEF Fourth Industrial Revolution Network, expands on the role humans might play.

The Fourth Industrial Revolution (4IR) is at the center of the current economic frontier. In reality, is Africa prepared for such changes?

Moving quickly and being agile are key principles of success in the 4IR. Any country can succeed if they take on this mindset. A few years ago, Rwanda saw the opportunities drones, a 4IR technology, brought to their country.

They helped save over 800 lives by delivering blood to remote villages. To scale this, the government worked with the World Economic Forum’s (WEF) drones’ team to create the world’s first agile airspace regulation. Now, we see countries in Africa and around the world looking to the Rwandan model.

What feasible solutions can  artificial intelligence (AI) offer in terms of forecasting natural disasters, droughts food security on the African continent?

AI can help predict diseases, increase agriculture yields and help first responders. It is a powerful tool for governments and businesses, but it needs a lot of data to be effective.

For AI to be all that it can be, countries and companies need to work together to build frameworks for better management and protection of our data and ensure that it is shared and not stored in silos. Data is the oxygen of the (4IR). If countries do not leverage data and have their policies in place, they will be left behind.

There is a growing concern that the 4IR will strip people of jobs, of which there is already a shortage. How true is this?

The world is going through a workplace revolution that will bring a seismic shift in the way humans work alongside machines and algorithms.

Latest research from the WEF forecasts that by 2025, machines will perform more current work tasks than humans, compared to 71% being performed by humans today.

The rapid evolution of machines and algorithms in the workplace could create 133 million new roles in place of 75 million that will be displaced between now and 2022.

Consumers have real concerns around the potential harm technology can cause in areas such as privacy, misinformation, surveillance, job loss, environmental damage and increased inequality. What ethical precautions are being considered in the robotics space?

Now more than ever, it is important to incorporate ethics into the design, deployment and use of emerging technology. Innovating in the 4IR requires addressing concerns around privacy and data ownership, while attracting the skills and forward-looking thinkers of the future.

There are big challenges and bigger opportunities ahead. We have seen many companies and countries create ethical and human rights-based frameworks. What’s important is they are co-designed with members of both communities along with academia, civil society and start-ups.

A multi-stakeholder approach will result in a more holistic set of guidelines and principles that can be adopted in many different industries and geographies.

What changes need to take place for the African continent to be on par with global developments, and are there tangible goals set?

The 4IR provides governments the opportunity to be global leaders in shaping the next 20 to 30 years of science and technology. It is important they create an environment where companies can innovate.

The other tenet is to be open to working across borders and learning from each other. The global health industry has access to mountains of data on rare diseases, but it is trapped within countries and sometimes even within the hospital walls.

If we can build trust and find innovative ways to share the data while protecting privacy, we can employ tools like AI to help us cure disease faster. Countries and companies need to have the right governance frameworks and mechanisms in place for these breakthroughs to happen. It is possible to do these things now, but we need to work together to make it happen.
