Future of 5G
By Susan Friedman, Brian Lavallée – 5G is coming, and with it comes the expectation of wireless speeds that are 100X or more what we experience today with 4G. In fact, one of the goals of 5G is to achieve maximum download speeds of 10 Gbps per user. This influx of traffic won’t come without a cost to the underlying networks that support it.
To succeed, mobile network operators (MNOs) will need more than just a new radio access network, they will also need fiber—and lots of it – to manage the massive increase in bandwidth that will come as billions more users, both human and machine, join the network.
5G is expected to be deployed strategically in different locations, especially in the early days. If consumers are expecting all 3G and 4G networks to be replaced with 5G, they’ll be disappointed. 5G is expected to complement 3G/4G where it makes sense. And depending on where service providers believe applications and use cases will be most lucrative, they can roll out speeds of up to 10 Gb/s.
This means if you’re in a rural community, chances are you probably won’t get 5G in the early days. In cities and metro areas you’ll see potential applications like enhanced mobile broadband, self-driving cars, video broadcast services, and other use cases that will require high-bandwidth and/or low-latency. So, service providers will deploy 5G in geographic areas where it makes economic sense. more> https://goo.gl/kmxQSs

A growing chorus of experts argue that they’re strangling the economy—and must be stopped.
By Frank Partnoy – Index funds have grown exponentially since John Bogle founded Vanguard in the mid-1970s.
The top three families of index funds each manage trillions of dollars, collectively holding 15 to 20 percent of all the stock of major U.S. corporations. Best of all for their investors, index funds have consistently beaten the performance of stock-pickers and actively managed funds, whose higher fees may support the Manhattan lifestyle of many bankers, but turn out not to deliver much to customers.
Concerns about the potential dangers of shareholder diversification first surfaced back in 1984, not long after index funds themselves did. Julio Rotemberg, then a newly minted economist from Princeton, posited that “firms, acting in the interest of their shareholders,” might “tend to act collusively when their shareholders have diversified portfolios.” The idea, which Rotemberg explored in a working paper, was that if investors own a slice of every firm, they will make more money if firms compete less and collectively raise prices, at the expense of consumers. Knowing this, the firms’ managers will de-emphasize competition and behave more cooperatively with one another. more> https://goo.gl/AWXivG

Sea Change: GE’s French Wind Turbine Factory Will Power Germany’s Renewables Revolution
By Tomas Kellner – GE is a relative newcomer to offshore wind. The company explored the field a decade ago and returned to the industry in 2015, when it acquired the energy assets of Alstom, and built its first wind farm in Long Island Sound near Block Island, Rhode Island, last year. As the inaugural offshore wind farm in the United States, the project made a splash even though it holds just five turbines. But Merkur, which will have 66 turbines, is a much bigger beast. “This one is special,” says Pascal Girault, who runs the Saint-Nazaire plant. “Everything is big.”
Girault spent the early part of his career managing supply chains for the car industry, but ramping up production for Merkur is no Sunday drive. Workers in Saint-Nazaire make generators and assemble nacelles for the 6-megawatt GE Haliade turbine. The nacelle is the casing on top of the tower that shelters the generator and other equipment. It includes some 30,000 components.
Adding to the task’s complexity, the composite blades for the machines’ 150-meter-diameter rotors come from GE’s LM Wind Power factory in Spain. The steel segments for the tower are being made in Germany and China. U.S. and European companies supply electronics and mechanical components for the converter and generator. “The scale and the speed of the project are challenging,” Girault says. more> https://goo.gl/GSScqV

By Larry Elliott – The assumption underlying the muted response is that there will be no war between the US and North Korea, nuclear or otherwise, and that the smart investment play is to buy into any dips.
The markets are part right. It still looks unlikely that Trump will sanction a pre-emptive strike. Kim knows that, which is why he would be dumb to up the ante by aiming some missiles into the sea off Guam first.
But the financial markets – and the broader global economy – could still turn nasty in an repeat of what happened 10 years ago even without a shooting war.
For a start, the world has never really recovered from the last crisis. Growth rates have been weak and have only been possible because years of low interest rates and quantitative easing have encouraged consumers and businesses to rack up large amounts of debt. As the economist Steve Keen notes in his new book Can we avoid another financial crisis (Polity), many countries have become what he calls debt junkies.
“They face the junkie’s dilemma, a choice between going ‘cold turkey’ now, or continuing to shoot up on credit and experience a bigger bust later.”
Keen says the countries to watch out for have two characteristics: they already have high levels of personal debt and have relied substantially on credit as a source of demand in the past five years. Australia, Canada, South Korea, Sweden and Norway are all on his list of candidates to be future debt zombies. But so is China. more> https://goo.gl/f7WBnq

By Raya Bidshahri – When it comes to climate change, government leaders and politicians must begin to think beyond their term limits and lifetimes. They must ask themselves not how they can serve their voters, but rather how they can contribute to our species’ progress. They must think beyond the short term economic benefits of fossil fuels, and consider the long term costs to our planet.
Climate change is considered one of the greatest threats to our species. If current trends continue, we can expect an increase in frequency of extreme weather events like floods, droughts and heat waves. All of these pose a threat to crops, biodiversity, freshwater supplies and above all, human life.
Here are examples of a few countries leading the way.
Denmark: Considered the most climate-friendly country in the world, Denmark is on the path to be completely independent of fossil fuels by 2050.
China: Home to the world’s biggest solar farm, China is the world’s biggest investor in domestic solar energy and is also expanding its investments in renewable energies overseas.
France: Thanks to the production of nuclear energy, representing 80 percent of nationwide energy production, France has already reduced its greenhouse gas emissions.
India: The nation is on the path to becoming the third-largest solar market in the world. Solar power has become cheaper than coal in India.
Sweden: Sweden has passed a law that obliges the government to cut all greenhouse emissions by 2045. With more than half of its energy coming from renewable sources and a very successful recycling program, the country leads many initiatives on climate change. more> https://goo.gl/PPrn3b
