Rotary car dumpers (aka wagon tipplers) are used for quickly emptying coal and ore from hopper cars. Traditionally, hopper cars emptied from the bottom.
Enthusiast Chester Hill praises Pittsburgh-based Heyl & Patterson, who build these behemoths:
This is the Single Rail Car Dumper that has been in operation over 15 years. Drummond Coal purchased Heyl & Patterson Equipment, and are now building the the first Quad Car Coal Dumper at the Drummond Port in Santa Marta, Colombia.
Here's a longer clip from a different type that shows the entire process, not just the dumping:

The programs Obama established to retrain coal miners are going begging in Pennsylvania, undersubscribed because the out-of-work miners they were established to help are convinced that Donald Trump wasn't bullshitting when he promised to bring back coal.

Last week's John Oliver segment on Robert E. Murray, CEO of the coal mining Murray Energy Corporation, noted that Murray had a history of litigation against his critics in the news media, including the New York Times, and predicted that Murray would go on to sue Oliver (Murray's lawyers had sent Oliver a letter warning him about this possibility, and promising to pursue litigation to the nation's highest courts).

Britain went a full day without using coal to generate power, reports the BBC. It's the first 24-hour period of inactivity there since 1882, when the world's first public coal-fired power plant was stoked at Holborn Viaduct in London.
But Ms O'Hara says that while the country makes the transition to a low carbon system, coal remains an important source of energy.
According to Gridwatch.co.uk, around half of British energy on Friday came from natural gas, with about a quarter coming from nuclear plants.
Wind, biomass, and imported energy were also used.
As in the U.S., coal power's been squeezed out by natural gas, a cleaner fossil fuel, though the trend is now toward renewable sources. Britain will close its coal-fired power plants down for good in 2025, supposedly.

A group of Wyoming legislators in the state's House and Senate -- all representing coal country and all avowed climate deniers -- have introduced a bill that would ban Wyoming power companies from using solar or wind power by 2019, and requires non-renewable power to account for 95% of the state's power by 2018.

What will happen to Trump's promise to revive the coal industry as the price of solar energy continues to drop?
"Not only did solar create almost 2% of all new U.S. jobs last year, those hires were concentrated in the states where solar is booming primarily because of market-friendly policies," said Amit Ronen, director of the George Washington University's Solar Institute.
Trump has also threatened to pull U.S. support for the Paris Agreement, which last year saw voluntary pledges by 195 nations to lower CO2 emissions. But the impact of such a move would be negligible at best in helping the coal industry, analysts said.
"Even if he did all those things..., which would require legislative hurdles, the economics still favor gas more as an energy generation source," said Colleen Kennedy, an oil and energy analyst with at Lux Research. "The economics just don't work out in favor of coal."

It's been a year since the Law and Justice Party won the Polish election, on familiar-sounding promises to drain the swamp and restore Poland to its former greatness: now school textbooks are being redesigned to downplay evolution and climate change and to recount a fanciful version of Poland's history; the government is mooting giving hoteliers the right to turn away customers based on sexual orientation or skin-color; a minister rejected an international accord against wife-beating because it subverted traditional gender roles; Parliament is about to get the right to choose which journalists may report from its debates; the guy in charge of national sex-ed curriculum believes that condoms give women cancer; a proposed law will virtually end opposition protests; and disloyal journalists at the "independent" state broadcaster have been purged.

The Federal Election Commission has deadlocked on a complaint about an employer who coerced his salaried employees into donating to a PAC he had started; the three Democratic commissioners voted to take action, the three GOP commissioners voted against, and that means that nothing will happen.

Centralia, Pennsylvania is Hell on Earth. It's the town where a 12-year old boy once fell into a pit that "suddenly appeared in his grandmother’s backyard. He grabbed onto a tree root, and his cousin pulled him out from the steam-emitting hole in the earth." The pit was caused by an underground coal fire that's been burning for over 50 years "and may burn for several more centuries."
Pricenomics has a good short history of Centralia, which is now mostly abandoned.

Maggie Koerth-Baker throws light on--and through--an opaque chemical mystery
At Time, Bryan Walsh reports on two pieces of news coming out of the aftermath of the Fukushima nuclear disaster
. First, the World Health Organization has released estimates of the health effects on the plant's workers, the people who were involved in shutting it down, and the local residents who lived closest to the plant when it went into meltdown. These people will have an increased risk of leukemia, thyroid cancers, and cancer, in general. But the increase isn't as large as you might have feared. Walsh does a very good job of breaking down the statistics, here. The second bit of news is, unfortunately, not so good. In Germany, which decided to phase out nuclear power in the wake of Fukushima, coal power is on the rise. And it's rising faster than the increase in renewable energy. Read the rest
One blazing hot afternoon in August of 2010, I stood on a mountain top in Alabama, staring at a styrofoam beer cooler upended over the top of a metal pole. Alongside me were a couple dozen sweaty engineers and geologists. That beer cooler was one of the few visible signs of the research project happening far below our feet.
Over the course of two months, scientists from the University of Alabama had injected 278 tons of carbon dioxide into the Earth. The goal was to keep it there forever, locked in geologic formations. The beer cooler was a key part of that plan. Beneath it sat the delicate electronic components of the monitoring system the scientists were using to make sure none of the captured carbon dioxide found its way out of the mountain. Beer coolers, it turns out, make great low-cost heat protection.
Carbon capture and storage—the process of removing carbon dioxide from factory and power plant emissions and trapping it where it can't reach the atmosphere—is an interesting idea. It has the potential to help us make our current energy systems cleaner as we work on building more sustainable systems for the future. With that in mind, the Department of Energy has seven regional research teams testing carbon capture and storage at sites around the United States.
So far, nobody in the United States has put this full process to the test at the scale that would be necessary in the real world. But, in the past couple of weeks, scientists at the Midwest Geological Sequestration Consortium began pumping carbon dioxide at a new site, one that is going to give us our best picture yet of what full-scale carbon capture and storage (CCS) will be like.

Earlier this week, I told you about a new study tracking radioactive fallout from the nuclear power plant disaster in Fukushima, Japan.
It started with a team of researchers in California, who had been monitoring radioactive sulfur in the atmosphere since 2009. Last spring, after an earthquake and tsunami critically damaged several reactors at the Fukushima Daiichi power plant, those researchers watched the levels of radioactive sulfur skyrocket, relatively speaking. The amounts of radioactive sulfur that reached the California coast weren't high enough to be a threat to humans, but they made a big impact on extremely sensitive monitoring equipment.
Using that data, the researchers were able to figure out where the radioactive sulfur came from and back-calculate how much would have been produced at the site of the disaster—information that can tell us something about how dangerous the disaster really was to people living nearby.
But these researchers weren't the first to collect radioactive isotopes from Fukushima on American shores. And they weren't the first to offer up improved estimations of how much radiation leaked from the damaged power plant in the early days of the disaster. I thought this study was interesting. But, like a lot of you, I was left wondering why it was important.
Then yesterday, I interviewed Antra Priyadarshi, the lead author on the peer-reviewed paper that was published about this study. And I realized I'd gotten the story all wrong. This paper is about radioactive sulfur from the Fukushima disaster. But it isn't about the Fukushima disaster. Read the rest
