Renewable Energy Comes to Tesla Magazine

Nikola Tesla: Renewable Energy Ahead of Its TimeSolar and wind energy, along with hydroelectric power, may seem like recent ideas, but Nikola Tesla had them in his sights a long, long time ago. As this post goes up on Science Traveler, the new Tesla Magazine goes to the printer. Joining the list of great authors for this issue is an article of mine called “Nikola Tesla Advocated Renewable Energy 100 Years Ago.” It’s an adaptation from my recent e-book, Nikola Tesla: Renewable Energy Ahead of Its Time, available on Amazon.

Tesla was right when he said “It seems that I have always been ahead of my time.” While everyone else was rushing to exploit new ways of mining coal – one of the dirtiest forms of fuel on our planet – and drilling for oil and gas, Tesla had already recognized that they were wasteful and finite. Only later did we learn that our burning of fossil fuels is also causing the planet to warm. Had we known then what we know now, perhaps more people would have listened to Tesla’s ideas at the time.

The article in Tesla Magazine will be on news stands soon, so look for it among other science-related magazines on the shelves. The photo below shows the July 2014 issue; the new issue features a graphic somewhat reminiscent of da Vinci’s Vitruvian man and highlights Tesla’s “The Problem of Increasing Human Energy.” As always, publisher Nenad Stankovic has done a wonderful job pulling together some great articles.

This is my second article in Tesla Magazine. I was fortunate enough to join other noted Tesla authors and leaders in the premier issue of July 2013. You can subscribe to the magazine here, and check out their Facebook page here.

Tesla Magazine TOC, first issue July 2013

It’s been a good week for my writing. I just had my article “Lincoln and the Rule of Three” published in The Lincolnian, a publication of the Abraham Lincoln Group of the District of Columbia. This week will also see publication of another article of mine in the newsletter of the Chesapeake-Potomac Regional Chapter of SETAC. Along with some editing of others publications and some works-in-progress – including a grant request involving filmmaker Ken Burns – I’m keeping busy.

Now, on to the book proposal!

Book Review – Angels and Ages: A Short Book about Darwin, Lincoln, and Modern Life by Adam Gopnik

Gopnik Angels and AgesThe title comes from the controversy (assuming you knew there was a controversy) over whether Edwin Stanton, upon Lincoln taking his last breath, said “Now he belongs to the ages” or “Now he belongs to the angels.” With this contrivance as a starting point Gopnik presents what amounts to six essays.

Gopnik does look at Lincoln and Darwin and their contributions, habits, beliefs, and psyches in ways different than do other writers. Whereas James Landers’ Lincoln and Darwin: Shared Visions of Race, Science and Religion (reviewed recently by me here) gets way into the weeds of comparison, Gopnik takes a more philosophical and less comparable approach. In doing so he reveals some interesting insights into how the two men thought, as well as their use of language (Lincoln the language of the law, Darwin of natural observation).

And yet, the language of the essays themselves tend toward the overtly literary. Often it seems the author is trying to impress the reader with his soliloquy rather than present an impression of the men he is profiling. The first and last chapters in particular seem more about Gopnik than Lincoln and Darwin. That said, the intervening four chapters, hopping between the two men, are worth wading through for the gems that may or may not be obvious to most readers.

I do recommend those interested in Lincoln and Darwin read the book, but for the bigger picture insights into their habits rather than the details that support them. For more comprehensive books comparing these two men born on the same day, check out the James Landers book mentioned above and a book by David R. Contosta called Rebel Giants: The Revolutionary Lives of Abraham Lincoln and Charles Darwin.

Where to Find Abraham Lincoln in Washington DC

Abraham Lincoln spent about six years in Washington, D.C. The first two were from 1847 to 1849 when he served his one term as a U.S. Congressman from Illinois. The last four – the last four years of his life – were as President of the United States during one of the most tumultuous times of our nation’s history. Many statues and other honors to our sixteenth president can be found in the city, and one of the oldest organizations dedicated to the celebration of his life is based here – the Lincoln Group of the District of Columbia.

Nikola Tesla and Renewable Energy – Discovering Hydrothermal and Geothermal Power

Nikola TeslaNikola Tesla believed that the thermo-dynamic process, i.e., the burning of fossil fuels, was “wasteful and barbarous.” He foresaw the limitations on supply and the inherent dangers to man and the environment (though even Tesla couldn’t anticipate the impacts of fossil fuels on climate change). “Whatever our resources of primary energy may be in the future,” Tesla argued, “we must, to be rational, obtain it without consumption of any material.” He believed that natural, renewable, sources of energy could “eliminate the need of coal, oil, gas or any other of the common fuels.” Two of the renewable energy sources that he investigated were hydrothermal and geothermal energy.

Tesla recognized that natural heat differentials exist in all three compartments of the environment – the oceans, the earth, and the atmosphere. Tesla saw the potential for a whole new source of energy from nature.

Hydrothermal

Tesla spent a great deal of effort determining a way to harness the temperature differential of the deep seas for power. The basic idea is that the “warmth of one layer” would be “brought into contact with the cold of another, to operate great power plants.”[iii] Tesla felt that such a system was practical to develop and operate. While he does discuss other natural sources of energy in his 1931 article “Our Future Motive Power,” most of the article is dedicated to analysis of the theory and practicality of hydrothermal energy from the sea.

Tesla dove into the project with his usual zeal, determined to create something completely new. The basic system relied on an apparatus that had existed for over a century, the cryophorus (“cold carrier”). It consisted of two large glass bulbs connected by a glass tube. The bulbs are partially filled with liquid, one bulb packaged in ice, “which is evaporated in one and condensed in the other.” After many calculations he felt the system could generate massive amounts of power

Tesla was elated. What a discovery!

Geothermal

Terrestrial powerThere are temperature differentials in the earth as well. In 1900 Tesla was already contemplating what today we call geothermal energy. In a somewhat long-winded and metaphysical treatise called “The Problem of Increasing Human Energy,” Tesla wrote that “it is a well-known fact that the interior portions of the globe are very hot, the temperature rising, as observations show, with the approach to the center at the rate of approximately 1 degree C. for every hundred feet of depth.”

Several scientists and adventurously minded dreamers had sought ways to harness this natural energy. French astronomer and physicist M. Camille Flammarion, for example, suggested that a massive hole could be bored through the crust of the earth to “sap the inexhaustible supply of heat” believed present in the Earth’s core. Among other complications, Flammarion’s idea had one huge drawback – the opening to the shaft would need to be “two hundred to three hundred yards, supported by a heavy, thick, cast-iron lining.” Flammarion insisted this plan was “practicable and possible;” in reality it was closer to delusional.

Tesla, on the other hand, felt the basic temperature differential principle was sound and that with his own discoveries (e.g., use of volatile fluids), very small diameter holes and shallow depths would be sufficient to power populated areas. Tesla felt the only requirement still to be met was “to find some economic and speedy way of sinking deep shafts.” If that could be achieved it would “open up unlimited resources of power throughout the world.”

By this time, however, Tesla was in his 75th year and without a laboratory or funds to be doing any groundbreaking research. He decided that developing these natural energy technologies “must be left to the future” and someone else. He also recognized that our energy infrastructure had already swayed toward use of “cheap” coal and oil, and that government and financial support for fossil fuels would make development of renewable resources more difficult. Even with these realities, Tesla was already anticipating the day when “our stores of coal and oil will be eventually used up” and other more sustainable energy resources would be necessary.

Abraham Lincoln, Ballooning, and the Technology of War – Redux

Abraham LincolnAbraham Lincoln is the only president to ever get a patent, an ingenious, though impractical, method for lifting boats over shoals. This interest in technology served him well during the Civil War as battles increasingly relied on mechanization for transportation, communication, and weaponry.

I’ve hinted at some of these things in previous posts and will be enlarging on this as my new book develops. As I do that, here are some relevant posts you may have missed:

James L. GreenAbraham Lincoln’s Air Force – Balloons in the Civil War: A discussion with James L. Green, a Director of Planetary Science with NASA and a worldwide expert on Thaddeus Lowe and the use of gas-filled balloons during the early part of the war. Green is working on a new book on the topic and was gracious enough to host me for a lunch discussion.

Organized by the Abraham Lincoln Library and Museum at Lincoln Memorial University in Harrogate, Tennessee, this exhibition explores how cutting-edge Civil War technological innovations captured Lincoln's fascination and impacted the conduct of the war.Abraham Lincoln and the Technology of War: A recent exhibit held in the Ford’s Theatre Center for Education and Leadership displayed telegraphs, weapons, and other artifacts reflecting various forms of technology that helped the North win the war.

Lincoln and the Tools of War by Robert V. Bruce: My review of the definitive treatment on the technology of weaponry in the Civil War.

Reflections on My Anniversary (or, Why I Became a Science Traveler)

The Traveling ScientistOne year ago today I left behind the first half of my life.  After more than 30 years as a working scientist I had decided to give up a comfortable salary for a life of (essentially) no income. I would become a poor starving writer.

It was the best decision I ever made.

I loved my previous life. Well, most of it. But the parts I didn’t like had grown in proportion to the parts that excited me. Using my skills, my knowledge, and my personal connections with colleagues and clients, I made a large amount of money – for others. Sure, my salary was nice enough, but increasingly the benefits of my labor went to others, and those others seemed decreasingly appreciative of that fact. Abraham Lincoln’s line from his Second Inaugural Address about  “wringing their bread from the sweat of other men’s faces” kept popping into mind. Not a perfect analogy, but close enough.

I learned a lot during all those years – about science, about business, about people. I also learned that science is often trumped by business concerns and people’s perceptions. I felt there was a growing need to communicate science to the public, and that scientists weren’t always very good at meeting that need. I decided to do something about that.

Coincident with this desire was some serendipity that led to publication of my first professional book, Tesla: The Wizard of Electricity. As the old saw grinds, “the stars aligned, angels’ voices rang down from the heavens” and all that not-so-scientifically-accurate metaphorical interlude. In real terms, stuff fell into place and it became clear this was the time to take the risk. So I did.

So where am I this one year later? I’ve traveled a bit, though not as much as I would have liked. One highlight of 2014 is an amazing trip to Argentina, with several smaller and more local trips throughout the year. I’ll squeeze in a few more jaunts before New Year’s and am busy planning for 2015 (Peru? China? Rushmore?). Science Traveling will play an increasingly important role in my future.

I’m also writing. Tesla: The Wizard of Electricity was back in Barnes and Noble stores mid-summer and was selling faster than it did last year (in fact, sales in the first 6 weeks already nearly matched all last year). To this I added a second book, an e-book exclusive to Amazon called Nikola Tesla: Renewable Energy Ahead of Its Time. More books are in the works, including my opus on Abraham Lincoln’s interest in science. Add in some manuscript editing, magazine articles, newsletter writing, and even some grant requests (plus my blogs, which I’ll reveal more about later), and yes, I’ve been keeping incredibly busy. All in an effort to bring science to the public – to make science fun again.

Finally, as I wind down my final year of the presidential cycle for the regional SETAC Chapter, I begin my first year in a leadership role with the Lincoln Group of the District of Columbia. As the director of outreach and education for LGDC I’m working with an engaged group of Lincoln scholars and aficionados to celebrate the life of Abraham Lincoln and ignite a new generation of interest. His “science geekiness” bridges my lifelong interest in Lincoln with my lifelong career in science. A perfect prelude to my forthcoming book. :)

I can confidently acknowledge that it’s a very happy anniversary indeed. The first of many.

10 Things You Don’t Know About Edison vs Tesla

Henry Rollins from imdb.comWay back in May I was contacted by a producer for a TV series for the History Channel called “10 Things You Don’t Know About,” hosted by Henry Rollins. They were interested in doing a program on the rivalry between Thomas Edison and Nikola Tesla. I spoke with the producer and provided my thoughts on what interesting facts they could include, and although I didn’t make it into the final program, it aired on September 7, 2014.

10 Things You Don’t Know About Edison vs Tesla

Rollins talks to an interesting array of experts and gets himself zapped by The Oatmeal, deep dives to the sunken luxury liner Oregon, and checks out Edison’s handwritten notes for a planned science fiction book. He also delves into Mark Twain’s role as Tesla’s “test dummy,” Edison’s most profitable invention (it’s not what you think and is actually quite ironic), and Tesla’s inspiration from Christopher Columbus. All in all it’s a great program.

You can also check out my own “5 Things You Didn’t Know about Nikola Tesla,” including how Tesla was both a showman and recluse, his interest in renewable energy, and why some people thought he was an alien from another planet.

Search for Telsa in the box above for more things you didn’t know about Nikola Tesla. And if you downloaded my e-book, Nikola Tesla: Renewable Energy Ahead of Its Time, please leave a short review and rating to help others discover Nikola Tesla.

Vietnam for Americans – Redux

VietnamI went to Hanoi before going to Hanoi became cool. Long after the Vietnam War but before the United States normalized relations with the unified communist nation, my first major trip out of the country was to a place that remains very much foreign to most Americans.

I posted about the trip two years ago but since then much has happened and many new people have come into my writing life. So I’m linking to the two posts below for those who may not have seen them.

Part 1: Hanoi on a Half-Shell: My initial impressions, the “shoe road,” and handmade silk shirts.

Part 2: A Cup of Tea and a Conversation I Didn’t Understand: Eating noodles while squatting on the street, and the best conversation I’ve ever had in which I didn’t understand a word that was said.

I hope you enjoy reminiscing with me…and getting a glimpse of a place most people will never see in person. I’ll have more on Vietnam (and other places) in the future here on Science Traveler.

The Gravel Roads of Patagonia

Thump.

My leg instinctively jerks away even though this is the tenth time a rock has stung the floorboards beneath my foot. The ping strikes my ears a split second after the thump has stimulated my autonomic reaction. Thump, ping, repeat.

This is Route 40, about 250 km of dirt – no, make that gravel – that Argentina considers a highway. Gravel roads are common here in the southern reaches of Argentina, which is more than can be said for road signs. Except for signs blazing the word “Desvio;” Detour. Desvio signs are ubiquitous along this side of the Patagonian Andes. Detour. The sign itself is obvious, but the road to which you’re detouring to? Well, not so much. We’re pretty much off the grid for the next several days, with hundreds of kilometers between towns, no phone service, no internet, and as I’ve been finding out, often no road.

Gravel roads in Patagonia

This is one of the better roads

I’m traveling with my long-time friend and Argentine host, Pablo. Even he has been having difficulty following the road. Desvio signs pop up as routinely as the gravel thumps against the bottom of the car. Several times we had to stop to ask for help locating the road, something that I wouldn’t have been able to do if I was traveling alone. If you don’t speak the language, it’s definitely a plus to be traveling with a native. We actually had to stop to ask the only person we had seen for many miles – the driver of a road grader leveling the mountain of rocks into a semblance of a highway.

Compounding the difficulty was that the gravel roads aren’t captured well on maps. You’ll be driving along a beautifully paved road and suddenly, with no other visible options, another sign pops up – Fin de Pavimento (End of Pavement). I should mention that we’re talking about roads that go on for tens or hundreds of kilometers with no outlets. You’re on this road going one direction, or you’re on it going the other direction. Even then, sometimes you can’t tell which direction you’re going.

Occasionally you’ll suddenly see an opening and get to pop back up onto a partially paved section in the middle of nowhere, but usually that pleasure is short-lived and you’re quickly back on gravel. The road surface ranges from packed dirt and pebbles (a rarity) to looser pebbles (more common) to coarse gravel (even more common) to what the official Krumbein Phi Scale of particle size officially calls cobble. Way too often the road is reminiscent of salmon spawning streams with rocks the size of bricks piled high in the middle of self-made tracks. These are the loudest, and scariest, clanks on the bottom of the car.

The car, by the way, is a Ford EcoSport SUV, so we sit high above the road surface. And still the stones thump.

My foot jerks away again. It actually feels like the rock is a direct strike to the bottom of my shoe.

Gravel roads are common in Pablo’s hometown of Bariloche as well, though mostly at the better end of the spectrum between “noisy but drivable” and “should be condemned as impassible.” So prevalent are gravel roads that Pablo says everyone adds one option to their new car purchase – steel plates on the underside of the car to protect the engine compartment and the gas tanks from puncture.

Thump.

But apparently not the floor boards in the back seat area. It’s a different world down here.
