Our economy is increasingly ruled by a few standout tech firms, and that’s not a good thing
Posted by Derick Lee in categories: business, economics
Our economy is increasingly ruled by a few dominant firms. We see them everywhere, from established giants Amazon, Facebook, Google, Apple, and Walmart to fast-growing newcomers like Airbnb, Tesla, and Uber. There have always been large companies and outright monopolies, but there’s something distinctive about this new generation of what some economists call superstar companies. They appear across a broad range of business sectors and have gained their power at least in part by adeptly anticipating and using digital technologies that foster conditions where a few winners essentially take all.
Superstar companies are dominating the economy by exploiting a growing gap in digital competencies.

This Supersonic-Speed Transit System Just Completed a Major Test
Posted by Dan Kummer in categories: Elon Musk, transportation
Hyperloop One this week announced that it completed the first full-scale test of its high-speed transportation system, a move the company hailed as the burgeoning technology’s “Kitty Hawk moment.”
The test vehicle only reached 70 miles per hour, a tenth of the company’s eventual target speed. But the firm felt assured enough to set another phase of testing for later this year, when they hope to reach 250 miles per hour. Eventually, the system could reach a top speed of 700 miles per hour, nearly the speed of sound.
The Hyperloop’s potential velocity has helped it captivate the public’s imagination ever since Tesla and SpaceX CEO Elon Musk popularized the concept in 2012. But the proposed system, a sort of high-speed train that uses aerodynamic pods propelled through a vacuum cylinder, is not just about speed, according to many of the people developing it since Musk open-sourced the idea. It’s about changing how we think about moving people and cargo, a $1.48 trillion industry in the United States alone.

Just 100 companies responsible for 71% of global emissions, study says
Posted by Aleksandar Vukovic in categories: climatology, sustainability
The report found that more than half of global industrial emissions since 1988 – the year the Intergovernmental Panel on Climate Change was established – can be traced to just 25 corporate and state-owned entities. The scale of historical emissions associated with these fossil fuel producers is large enough to have contributed significantly to climate change, according to the report.
A relatively small number of fossil fuel producers and their investors could hold the key to tackling climate change.

Warnings From Antarctica
Posted by Aleksandar Vukovic in categories: government, sustainability
Greenland’s ice sheet, the planet’s second largest after Antarctica, is melting at an alarming rate, losing an estimated 90 cubic miles of ice a year. The melt water that ends up in the ocean is raising sea levels. And then there are the countless glaciers in the Alps, Andes, Himalayas, Rockies and Tibetan Plateau, all melting as our unceasing carbon dioxide emissions — a staggering 35 to 40 billion tons a year — trap more and more heat.
As the Trump administration dismantles the federal government’s efforts to respond to global warming, the natural world has come calling with a reminder: An iceberg the size of Delaware broke off Antarctica’s Larsen C ice shelf in recent days, yet another indication of the rapid change now occurring on the world’s iciest continent.
This is the third floating ice shelf in recent years in Antarctica’s Weddell Sea to fully or partly break up, the first two subverted by warming ocean waters and air temperatures. The Larsen A broke up in 1995. Seven years later, after months of unusually warm temperatures, the Rhode Island-size Larsen B shelf became riddled with meltwater ponds, then fell apart virtually overnight, shattering into millions of pieces. Now a 120-mile-long chunk of the Larsen C has calved, forming one of the largest icebergs ever observed.
