Clinton Talks Up Clean Coal: Revitalize Coal Country. @oileconomyfocus
Fresh off a bounce in the polls, Hillary Clinton is promising to revitalize Pennsylvania communities hurt by a downturn in the coal and steel industries.
Jon Delano of KDKA-TV, part of CBS News, interviewed Clinton in Philadelphia on her policies for helping workers in these industries, and here is an extract:
JD: Can we bring back coal jobs as Donald Trump says? Can we bring back steel jobs?
HC: Well, we can certainly bring back steel jobs because once we really handle the unfair trade practices that have undercut our steel industry causing layoffs and plant closures, weâ€™re going to make it really clear to the rest of the world weâ€™re not sitting by and watching our steel industry go any further down.

Solar power has big limitations. This wonder material could change that
The silicon solar cells that currently dominate the world market suffer from three fundamental limitations. A promising new way of making high-efficiency solar cells, using perovskites instead of silicon, could address all three at once and supercharge the production of electricity from sunlight.
The first major limitation of silicon photovoltaic (PV) cells is that they are made from a material that is rarely found in nature in the pure, elemental form needed. While there is no shortage of silicon in the form of silicon dioxide (beach sand), it takes tremendous amounts of energy to get rid of the oxygen attached to it. Typically, manufacturers melt silicon dioxide at 1500 to 2000 degrees Celsius in an electrode arc furnace. The energy needed to run such furnaces sets a fundamental lower limit on the production cost of silicon PV cells and also adds to the emissions of greenhouse gases from their manufacture.
Perovskites (a wide-ranging class of materials in which organic molecules, made mostly of carbon and hydrogen, bind with a metal such as lead and a halogen such as chlorine in a three-dimensional crystal lattice) can be made much more cheaply and with fewer emissions. Manufacturers can mix up batches of liquid solutions and then deposit the perovskites as thin films on surfaces of virtually any shape, no furnace needed. The film itself weighs very little.

Clarification on What Is Solar Technology
he idea of using sunlight as an energy source is not so new. In 1839, for the first time, this effect was discovered by Alexandre Edmond Becquerel. He found in some experiments with electrolytic cells that current flows are little more light than in the dark. However, it will still take some time before this discovery could be used in practice.
1883 the first forerunner of today’s solar cells was developed, it was built by Charles Fritts. 1921 managed to Albert Einstein, the theoretical explanation of this effect, for which he received the Nobel Prize in Physics. Two years later, the effect could also be confirmed in an experiment, and so he also received a Nobel Prize.

The Permian Outstripping Rival U.S. Oil Producing Regions
Very informative charts help illustrate the extent to which the Permian basin is outstripping its rivals in terms of investor interest and deal flow. Confidence is not only illustrated in merger and acquisitions activity but also in how much companies are currently willing to invest in their own future. Capital expenditure plans are lower and less bullish than a year before, but operators are still displaying a greater level of confidence in being able to fund robust capex spends.

Vladimir Putin was interviewed by Bloomberg News Editor-in-Chief John Micklethwait in Vladivostok
Russian President Vladimir Putin was interviewed by Bloomberg News Editor-in-Chief John Micklethwait in Vladivostok on the eve of the second Eastern Economic Forum. The interview covered whether he would run in the next 2018 elections, his opinions on the US General Election, Syria, OPEC, the Rosneft sale, and Japan. With regard to the subject of oil – which occurs around half way through the full Bloomberg transcript of the interview – Putin said that Russian oil and gas companies, but mainly the oil companies, have invested 1.5 trillion rubles, and with the state’s investment in the pipeline network and electricity sector included the overall investment in energy added up to 3.5 trillion rubles in the past year. A quite significant figure considered Putin. He noted that Russia is the world’s leader in terms of natural gas exports with a global share of about 20 percent. Micklethwait asked him if Russia would be happy in a world where the Russian state had less than 50 percent ownership of certain big companies. Putin answered that Russia did not see anything horrible in this saying that when foreign shareholders – investors – took 50 percent of a certain company the contributions to the federal budget, tax payments, increased several times immediately and the company’s efficiency didn’t deteriorate at all. So from the viewpoint of the state’s interests, Putin considered that Russia had had a more positive than negative experience with regard to this. Putin added that the year before last oil and gas revenue accounted for 53 percent of budget revenue but this year it will be about 36 percent. Structural changes are also taking place, he said, not only in terms of price, but also about distribution, economic growth, and about the expansion of certain industries. He gave the example that whereas industrial production growth across the country is at 0.3 percent, in the Far East where the Economic Forum is being held, industrial production growth is 5.4 percent.

IEA Oil Glut
IEA: Oil Glut to Stay to Late 2017
OCT-2016. According to the International Energy Agency (IEA) the oil glut in global oil markets will last for longer than previously thought, persisting into late 2017 as demand growth slumps and supply proves resilient. “Demand growth is slowing and supply is rising,” adds the IEA, “Consequently, stocks of oil in OECD countries (members of the Organization for Economic Cooperation and Development) are swelling to levels never seen before.” The combination of faltering demand and increased OPEC output pushed oil inventories in developed nations to a record in July, at 3.1 billion barrels. Harry Tchilinguirian, head of commodity markets at BNP Paribas in London, considers that “OPEC’s long game got a little longer, implying the need for oil prices to remain lower for longer to spur the necessary adjustments in supply”. Also with regard to OPEC Olivier Jacob, managing director of the consulting company Petromatrix GmbH in Zug, Switzerland, says that the organization is “trapped” since “Non-OPEC supply has been able to adjust better than expected to the lower oil prices.”

How can thermoelectric generators be made more efficient?
Thermoelectric generators (TEGs) are a promising new way to produce electric energy directly from heat. But there is one remaining problem: the low efficiency.
Today, TEGs can have efficiencies of up to 10%. The biggest challenge here is that we want the TEGs to have high electrical conductivity but low thermal conductivity. As you can see in the screenshot of the NakedScientists' video on TEGs, the used materials conduct charge carriers like electrons - which is what we need to get an electrical voltage at the ends of the material. But the materials also conduct heat - and that's not so good, because this thermal conductivity leads to a decrease of the temperature difference between the two ends and therefore decreases the efficiency of the TEG.

CAODC 2017 forecast
Canadian operators seen boosting drilling next year. By @WorldOil @Tech_Flo
CALGARY, Alberta -- The Canadian Association of Oilwell Drilling Contractors (CAODC) has released its 2017 drilling forecast.
According to a statement on the association's website, CAODC is projecting that 4,665 wells—an increase of 1,103 from 2016 (3,562)—will be drilled next year. Meanwhile, operating days are projected to reach 48,980—an increase of 8,577 from 2016. The rig fleet is expected to decrease by 55 to 610.
“After record low utilization rates in 2016, it would be difficult to suggest 2017 could be anything but better. Weak commodity prices coupled with abnormal political and social factors, has led to sustained challenges for the industry. While the price of WTI is projected to stabilize somewhat, continued uncertainty surrounding pipeline infrastructure, and a looming price on carbon, continue to push Canada to the back of the line with respect to long-term investment,” CAODC said.
