Yard Ramp Guy Blog: The Magnificent Magnesium Ramp
I'm so thrilled about this week's Yard Ramp Guy blog ⏤ honoring and appreciating history and longevity (and magnesium!) ⏤ that I've bumped my call-out to the top of this entry.
I heartily encourage you to check it out HERE.
A Cup of Java is Good for Us
My good friend Jeff Mann, the true Yard Ramp Guy, has asked me to revisit some of my original posts. This week in my From the Archives series: pour yourself a cup of coffee and read this.
Fun fact: We have coffee to thank for economics, geology, and countless other scientific and intellectual advancements.
Seventeenth century Scotland was a nasty place in many ways, filled with poverty, disease, and chronic alcoholism—in great part because the water wasn't safe to drink. Raids from highland clans were also a fact of life.
By the eighteenth century, however, things had changed radically. The highland clans were defeated, the economy was looking up, and things were just improving all around.
And then coffee showed up.
All of a sudden, you had something to drink that would neither make you sick, like the water, or drunk, like the ale.
Intellectuals started gathering in social clubs and became massively more productive. Among those intellectuals were Adam Smith, the father of modern economics; James Hutton, the father of modern geology; Robert Burns, one of the greatest English language poets of all time (as well as Scots language poets); Joseph Black, the chemist who discovered magnesium and carbon dioxide; philosopher David Hume; and many more.
What's more, they weren't operating alone. They largely all knew one another. Joseph Black, James Hutton, and Adam Smith were all incredibly close friends.
This was a movement focused on empiricism and reason, and it came to be known as the Scottish Enlightenment.
These changes weren't just limited to Scotland, either. Everywhere coffee traveled, there tended to be increases in productivity, intellectual development, and general economic well-being of a nation (though not necessarily for individual members of a nation.)
Coffee is by no means an unadulterated good in history, especially not at the growing end of the supply chain, but it did radically change history wherever it arrived.
Pretty impressive for a beverage.
What a Gas
My good friend Jeff Mann, the true Yard Ramp Guy, has asked me to revisit some of my original posts. This week in my From the Archives series: the essential nature of helium.
The federal government has maintained a helium storage program since WWI, with the express purpose of making sure that America never falls behind in, um, a zeppelin arms race.
The Federal Helium Program is often viewed as one of the biggest boondoggles the government keeps funding. Both Reagan and Clinton tried to get rid of it. They couldn't have been more wrong, though.
Even apart from the fact that the program pays for itself with the proceeds of the helium it sells to U.S. companies, the helium program has plenty of other benefits to keeping it around.
First off, helium provides 42 percent of the nation's supply of unrefined helium gas. Second, it's already all stored in a huge porous rock formation below the Texas Panhandle, so there isn't a lot in terms of maintenance fees.
Even if we did need to harvest more, it's not that difficult. Among other things, helium is a byproduct of harvesting natural gas in the Midwest. Most importantly, helium is surprisingly essential to industries across the board.
Here's a non-exhaustive list of helium's uses:
- Airships are making a major comeback (see HERE), and they obviously need lots of helium.
- Cryogenic purposes. Not just freezing dead bodies, but cooling the magnets in MRI scanners and other similar uses. Helium makes an extremely effective coolant and is part of the process of making oxygen-hydrogen rocket fuel.
- Creating stable pressurized atmospheres. Deep sea divers often use atmospheric mixes that include helium.
- Arc welding materials that are contaminated by air or nitrogen.
- Supersonic wind tunnels.
- Gas chromatography—a method of analyzing the components of chemicals.
- As a protective gas in growing silicon and germanium crystals.
Last, and certainly not least: those party balloons that float and hug the ceiling? Filled with helium. I just bought 30 of them for my grandson’s birthday party. Birthdays just wouldn’t be as fun without helium.
Or: Tainted Tuna Tartare
My good friend Jeff Mann, the true Yard Ramp Guy, has asked me to revisit some of my original posts. This week in my From the Archives series: oh, that flotsam and jetsam...
There's a floating patch of garbage, larger than Texas, in the middle of the Pacific Ocean.
The Pacific Ocean contains huge, slow moving gyre-shaped currents. Debris that drifts into the calm centers of those gyres tend to stay there. It’s similar in some ways to the nearly self-contained gyre that’s the Sargasso Sea but caused by different things.
The debris that drifts into the biggest one, the North Pacific Subtropical Convergence Zone? Bits of plastic.
When you sail into the Great Pacific Garbage Patch, you won't see a lot of chunks of garbage floating around, and you certainly can't walk on it. Instead, the plastic has broken down into tiny particles that float in the upper layers of the water. Fish frequently mistake it for food and often starve, with stomachs full of plastic.
Many other lifeforms find the plastic poisonous, and as the plastics break down, they leak toxic chemicals into the environment, including ones as nasty as PCBs. (Don't read about PCBs unless you really want to freak yourself out, but if you must, click HERE).
There are even bacteria that have learned to eat the plastics, but they end up producing even nastier toxins much of the time.
As the toxic chemicals and plastics are ingested by fish, jellyfish, and other marine animals, they grow increasingly concentrated, up the food chain, as predators eat toxin-laden critters. Many of those predators in turn, like tuna (which are shockingly high up the food chain) contain much higher levels of toxins than the water around them. And then we, the people in this story, eat them. Bon appétit.
The Great Pacific Garbage Patch isn't alone. There is another major gyre in the Pacific, two in the Atlantic, and one in the Indian Ocean. They all contain garbage patches of their own. What are we doing to clean up these patches? Not much yet, other than research, really. There are lots of plans in the air, but not that much funding.
A Cautionary, er, Tail
My good friend Jeff Mann, the true Yard Ramp Guy, has asked me to revisit some of my original posts. This week in my From the Archives series: that beach only looks beautiful...
Caribbean beaches are beautiful, even by the standards of tropical beaches, which are pretty high to start with. They're also made largely of poop. Parrotfish poop, to be specific.
(Okay, full disclosure: I’m not currently on a beach. I write this on a Sunday morning, in my robe, from my man cave next to the house here in suburbia. I’m safe. And thanks for caring.)
Move past the thought of that, and it’s a fascinating process:
The brilliantly colored parrotfish possesses a hard beak it employs for eating coral. The fish grinds up the coral in that beak to get at algae and other marine microorganisms growing on it, digests the algae, and then poops out the ground-up coral as a fine sand.
Parrotfish produce a LOT of sand, too. A single green humphead parrotfish can produce more than 200 pounds of sand each year. As much as 85% of the sand on many of these beaches is produced by parrotfish.
Watch it in action HERE, if you dare.
People used to think that parrotfish just ate coral for the polyps and were damaging the reefs. It turns out, though, that most parrotfish species go primarily for dead coral, clearing it for new coral to grow. So, they’re providing a sort of public service.
Parrotfish also eat large amounts of sea sponges, which grow faster than coral and can smother young ones. As it turns out, our parrotfish have a largely symbiotic relationship with the corals they eat. And as we learn more and more about the world, we begin to find more and more of these relationships.
It's not just the Caribbean that owes its beaches to parrotfish. The Maldives, the white sand beaches of Hawaii, and other locations around the world do, as well.
Gorgeous white sand beaches in tropical areas around the world are all made of poop. A little gross, I know. Which is exactly why I'm telling everyone: I’m simply trying to clear out a few of you so that my next beach experience is less crowded.
