New Projects Create a Foundation for Next-Gen Flexible Electronics
By Josh Brown – Four projects set to move forward at the Georgia Institute of Technology aim to lay the groundwork for manufacturing next-generation flexible electronics, which have the potential to make an impact on industries ranging from health care to defense.

Researchers at Georgia Tech are partnering with Boeing, Hewlett Packard Enterprises, General Electric, and DuPont as well other research institutions such as Binghamton University and Stanford University on the projects.

Flexible electronics are circuits and systems that can be bent, folded, stretched or conformed without losing their functionality. The systems are often created using machines that can print components such as logic, memory, sensors, batteries, antennas, and various passives using conductive ink on flexible surfaces. Combined with low-cost manufacturing processes, flexible hybrid electronics unlock new product possibilities for a wide range of electronics used in the health care, consumer products, automotive, aerospace, energy and defense sectors.

“Flexible electronics will make possible new products that will help us address problems associated with food supply, clean water, clean energy, health, infrastructure, and safety and security,” said Suresh Sitaraman, a professor in the George W. Woodruff School of Mechanical Engineering, who is leading Georgia Tech’s flexible electronics activities. more> https://goo.gl/qjx3UT

From bedroom to boardroom, Supreme Court is in your business

By Nancy Benac – The influence of the court’s nine justices is hard to overstate. So pay attention as Congress prepares to take up the nomination of Judge Neil Gorsuch to join the high court.

From the time Americans roll out of bed in the morning until they turn in, the court’s rulings are woven into daily life in ways large and small.

“From the air you breathe and the water you drink to the roof over your head and the person across from you in bed, the Supreme Court touches all of that,” says Elizabeth Wydra, president of the Constitutional Accountability Center.

Charged Up: GE Shows Investors Its Energy Playbook
By Tomas Kellner – The acquisition of Alstom’s energy assets delivered $1.5 billion in synergies in 2016, $300 million above GE’s original five-year target for Alstom synergies, GE’s Chief Financial Officer Jeff Bornstein told investors at a conference in New York held by GE’s Power and Renewable Energy businesses last week. “Alstom makes us more competitive,” Bornstein said. “It broadens the service base and creates long-term incremental value.”

Jobs, cash, costs and software were the key themes at the conference. Bornstein said GE Oil & Gas was now “applying the same methodology” to its planned merger with Baker Hughes. “The businesses are very complementary,” he said. “It’s going to be a merger of equals.” Bornstein said he was “highly confident” the deal would “deliver a lot more value than $1.6 billion” in synergies by 2020, the target the companies released when they announced the deal last October.

Bornstein also talked about the need to speed up the shrinking of GE’s $25 billion in “structural costs,” which are funding support functions, R&D, corporate operations and other expenses. more> https://goo.gl/z07MkD

A Brief History of the Grand Unified Theory of Physics

By Lawrence M. Krauss – Each time we peel back one layer of reality, other layers beckon. So each important new development in science generally leaves us with more questions than answers. But it also usually leaves us with at least the outline of a road map to help us begin to seek answers to those questions.

The successful discovery of the Higgs particle, and with it the validation of the existence of an invisible background Higgs field throughout space (in the quantum world, every particle like the Higgs is associated with a field), was a profound validation of the bold scientific developments of the 20th century.

As elegant as this idea might be, it is essentially an ad hoc addition to the Standard Model of physics—which explains three of the four known forces of nature, and how these forces interact with matter. It is added to the theory to do what is required to accurately model the world of our experience. But it is not required by the theory. The universe could have happily existed with massless particles and a long-range weak force (which, along with the strong force, gravity, and electromagnetism, make up the four known forces). We would just not be here to ask about them. Moreover, the detailed physics of the Higgs is undetermined within the Standard Model alone. The Higgs could have been 20 times heavier, or 100 times lighter.

Why, then, does the Higgs exist at all? And why does it have the mass it does? (Recognizing that whenever scientists ask “Why?” we really mean “How?”) If the Higgs did not exist, the world we see would not exist, but surely that is not an explanation. Or is it? Ultimately to understand the underlying physics behind the Higgs is to understand how we came to exist. When we ask, “Why are we here?,” at a fundamental level we may as well be asking, “Why is the Higgs here?” more> https://goo.gl/UCn3w8

The Electric Car Rush Started Too Early

By Leonid Bershidsky – The hyped-up electric vehicle revolution, driven by a fear of being left behind and overzealous regulation, may be forcing car companies to make expensive mistakes. The modern electric vehicle is conceptually inconsistent with how people want to use cars, and in many countries the environmental effect of switching to EVs is negligible.

To spend heavily on electrification, companies have to believe forecasts from experts who don’t have skin in the game. McKinsey, for example, recently put out a report arguing that consumer interest in electric cars is growing. All automakers need to do is keep up incremental improvements and advertising more to increase awareness.

That could turn out to be wishful thinking, because the modern EV caters to a specific-use scenario that increasingly doesn’t work for today’s consumers. more> https://goo.gl/kg48lX

The Future of Growing Cities Rests in Smart Transit

By Robert Garcia – Transportation isn’t just about moving people around; it’s also about moving goods. As home of the nation’s largest port complex, Long Beach has made significant strides to transport goods in more efficient and environmentally sustainable ways, and we are quickly becoming a model for ports across the globe.

Long Beach is now ranked in the top 10 cities nationally for walkability and bike-ability. And we have even used technology to make it easier for those who elect to drive, with apps like EZParkLB, which shows parking availability and pricing in real time. In addition, we have partnered with Mercedes Benz to launch an electric vehicle charger giveaway program to encourage more people to adopt sustainable technology.

Through the Green Port Policy, the Port of Long Beach has successfully introduced smart technologies over the past twenty years, bringing us closer to our goal of becoming a zero-emissions facility. We have reduced greenhouse gases significantly by using electric equipment on the docks and are currently in the process of converting existing vehicles to clean cargo-handling technologies. Other advances include providing shore power for ships, allowing engines to be shut down, and on-dock rail that shifts more than 30 percent of the cargo shipments from trucks to trains. And our newest terminal, Middle Harbor, uses the most advanced automated technology available to move containers from ships and into economic markets throughout the country. more> https://goo.gl/XBpdXi

Four-Stroke Engine Cycle Produces Hydrogen from Methane and Captures CO<sub2
By John Toon – When is an internal combustion engine not an internal combustion engine? When it’s been transformed into a modular reforming reactor that could make hydrogen available to power fuel cells wherever there’s a natural gas supply available.

By adding a catalyst, a hydrogen separating membrane and carbon dioxide sorbent to the century-old four-stroke engine cycle, researchers have demonstrated a laboratory-scale hydrogen reforming system that produces the green fuel at relatively low temperature in a process that can be scaled up or down to meet specific needs. The process could provide hydrogen at the point of use for residential fuel cells or neighborhood power plants, electricity and power production in natural-gas powered vehicles, fueling of municipal buses or other hydrogen-based vehicles, and supplementing intermittent renewable energy sources such as photovoltaics.

Known as the CO2/H2 Active Membrane Piston (CHAMP) reactor, the device operates at temperatures much lower than conventional steam reforming processes, consumes substantially less water and could also operate on other fuels such as methanol or bio-derived feedstock. It also captures and concentrates carbon dioxide emissions, a by-product that now lacks a secondary use – though that could change in the future.

Unlike conventional engines that run at thousands of revolutions per minute, the reactor operates at only a few cycles per minute – or more slowly – depending on the reactor scale and required rate of hydrogen production. And there are no spark plugs because there’s no fuel combusted. more> https://goo.gl/h4K7fV

Will President Trump derail the U.S. economy?

By George L. Perry – The stock market should like these economic proposals for several reasons.

Lower tax rates directly raise after-tax profits. Faster expansion from the fiscal push means higher profits. And reducing regulations cuts costs and raises profits. Banks, which are a clear target for deregulation, also benefit from higher interest rates that raise lending profits. No surprise their stocks have been the best performers in the market rally.

he impact of these budgetary policies in the longer run are more murky.

Today’s Congress is likely to give the Administration most of what it asks for. And one big risk in this is that budgetary projections will be made based on dynamic scoring that assumes the programs produce large increases in productivity growth, and so project unrealistically fast growth in the economy’s potential output and revenues.

The CBO and Finance Committee make professional assessments of these supply-side effects in estimating future budgetary impacts of tax changes. But the Administration will push for more generous estimates of future revenues that will make the tax and budget proposals more palatable at present.

This will only put off dealing with long-run budget deficits and a rising ratio of debt-to-GDP that is projected as the population ages. The adverse effects of swelling debt will be someone else’s problem at some future time. more> https://goo.gl/th1nzJ

GE Just Turned the World’s Most Powerful Jet Engine Into A 65-Megawatt Power Plant
By Tomas Kellner – GE is taking the world’s largest jet engine and turning it into a power plant. The machine’s beating heart comes from the GE90-115B, which is the largest and most powerful jet engine, capable of producing 127,900 pounds of thrust, according to Guinness World Records. The electricity generator, which GE calls LM9000, will be able to generate a whopping 65 megawatts — enough to supply of 6,500 homes — and reach full power in 10 minutes.

The technology is also a good example of what GE calls the GE Store — the system of sharing technology, research and expertise among its many businesses. Today, aeroderivatives power towns and factories but also oil platforms and ships. more> https://goo.gl/dSwnhF

Donald Trump’s Global Agenda: What Have You Got to Lose?

By Stewart M. Patrick – Taken at face value, Trump’s ambitions portend a rupture with more than seven decades of U.S. global engagement dating from the end of World War II—as well as a break with older American values.

They signal a new U.S. global role that is more insular, transactional, and narrowly interest-driven. Gone is any mention of U.S. global leadership, the promotion of universal values, or the defense of a “free world.”

The pursuit of world order will be replaced by the art of the deal.

At this stage of the presidential transition, it is impossible to know whether Trump will actually govern as he campaigned. Perhaps his campaign pronouncements were just red meat tossed to his populist, isolationist base and should not be taken literally as a guide to policy.

Perhaps. But for now, let’s assume that he meant what he said … more> https://goo.gl/HOO1Dz
