Elon Musk: Electric Cars Are Greener (Even if They’re Powered By Coal)

You don’t have to be a mechanical engineer or a chemist to know that a vehicle is only as green as the fuel that powers it. Accordingly, a common critique of electric vehicles is that they’ll do little to mitigate the climate problem if they draw electricity that’s generated from carbon-intensive sources. Since coal — the dirtiest source out there — accounts for nearly half our power generation, it seems unlikely that putting new electric cars on the road would do much in the short term to reduce carbon-dioxide emissions.

Or would it?

In interview with the Wall Street Journal (sub. req), Tesla Motors CEO Elon Musk points out the fallacy of the logic underpinning the above paragraph:

Even if you draw electricity from coal, or natural gas or even directly from oil, because stationary power plants are so much more efficient than small gasoline engines in cars, an electric car actually ends up getting more range for a given amount of, say, coal or oil that’s burned than an a gasoline car gets. In other words, the CO2 per mile is actually less for an electric car even if it’s coming from a high CO2 source like coal.

This is the first time I’ve heard this reasoning mentioned in the mainstream press. As far as I can tell, coal power plants have efficiency rates between 28 percent and 45 percent. Gasoline engines, meanwhile, fare much worse:

Only about 15 percent of the energy from the fuel you put in your tank gets used to move your car down the road or run useful accessories, such as air conditioning.

Hmm.

One point that Musk doesn’t address is the efficiency losses that occur during electricity transmission and distribution. I’m not an electrical engineer, so I’ll defer to anyone out there who’s reading to either corroborate or dismiss Musk’s assertion.

Regardless of where we are now, Musk agrees that we’ll need to find newer, more sustainable sources of energy moving forward. (This is perhaps not that surprising, given his role as a chairman of SolarCity.)

Long term, we have to find sustainable power generation and sustainable transportation. And even if electric cars weren’t there, we’d still need to get sustainable power generation.

The interview is definitely worth a watch. Beyond Tesla, topics covered include: SpaceX, which Musk forecasts could have a person on Mars within ten years; and Robert Downey Jr.’s character Tony Stark in “Iron Man.” (RDJ apparently visited Musk while working on the role.)

Well I’ll Be Damned: Radiation in Hong Kong, New York Tops Tokyo’s

You’ve read the headlines: Radiation Likely from Japan Found in Spokane MilkRadiation from Fukushima plant detected in Sacramento, EPA says; Potassium Iodide Tablets Sold Out in US. With the on-going calamity in Japan, you’d think everyone would have reason to run for the hills.

Japan's nuclear crisis: ho-hum?

Except not.

As relayed by Bloomberg, business as usual radiation levels in cities like Honk Kong and New York regularly exceed those in Tokyo, even as Japan struggles to keep its nuclear crisis from unraveling further:

The radiation level in central Tokyo reached a high of 0.109 microsieverts per hour in Shinjuku Ward yesterday, data from the Tokyo Metropolitan Institute of Public Health show. That compares with 0.14 microsieverts in the Kowloon district of Hong Kong, the Hong Kong Observatory said on its website. A person is exposed to 50 microsieverts from a typical x-ray.

Oops. This news is in line with the underlying thesis that the public (myself, included) almost always overestimates the risks associated with rare, scary events. Policy makers and media folks, take note.

Notes on Libya’s Oil, Money

Michael Levi makes some good points, suggesting that Libyan oil isn’t coming back anytime soon:

If Khadaffi manages to hold on, it will be brutal. There is no way that sanctions on Libya would be lifted quickly. The West might resign itself to a Khadaffi victory, but it will not be willing to line his pockets. Non-Western oil companies would be hard pressed to fill in, both because of technical demands, and because of the tricky international politics that would be involved.

In addition, regardless of who prevails, worker safety will be a lingering concern. Foreign oil companies are not going to send their workers back in until they’re confident that they’ll be safe. It will take some time for such confidence to be established.

According to what I’ve read this past week, about two-thirds of the country’s oil production is offline. And, after his forces made gains this week, Qaddafi doesn’t look like he’s heading for the exit just yet. His regime also has considerable financial resources, which Daniel Drezner puts in context:

Even the tightest financial sanctions don’t matter at this point. Qaddafi possesses far more financial reserves than, say, the Ivory Coast’s Laurent Gbagbo — and yet Gbagbo has managed to stay in power for five months. Sanctions should eventually work in the Ivory Coast, but they’re not going to work anytime soon in Libya.

Oil closed down about three percent on the week.

Happy Mitochondria, Happy Gonads

Some recent research suggests that exercise may promote healthy mitochondria — you know, those tiny organelles that we all learned about in high school bio class?

Mitochondrion

Refresher: mitochondria make ATP, a magical compound that powers all cellular function. (I’m pretty sure it’s also what Red Bull is made of.) Also as you may remember, mitochondria have their own DNA (kind of weird) and replicate on their own.

As it turns out, getting regular exercise may help keep your mitochondria happy. Led by Dr. Mark Tarnopolsky, a team of researchers at McMaster University in Ontario studied a bunch of mice. One group was kept sedentary; the other was permitted to run on a wheel three times a week. All the animals had a genetic flaw limiting their cells’ ability to repair mitochondrial damage that occurs during replication. As a result, at three months of age (approximately 20 years old in human terms) the mice’s mitochondria started malfunctioning.

As Gretchen Reynolds of NYT relays,

By the time they reached 8 months, or their early 60s in human terms, the animals were extremely frail and decrepit, with spindly muscles, shrunken brains, enlarged hearts, shriveled gonads and patchy, graying fur. Listless, they barely moved around their cages. All were dead before reaching a year of age.

Except the mice that exercised.

Turns out that, despite their predisposition for shabby mitochondria, the mice that were permitted to exercise fared much better than their lazy, decrepit counterparts. They exhibited healthy pelts of fur and retained almost all their muscle mass and brain volume.

Not to be overlooked, the exercising mice also had a better shot at having a decent sex life in their later years:

While Dr. Tarnopolsky, a lifelong athlete, noted with satisfaction that active, aged mice kept their hair, his younger graduate students were far more interested in the animals’ robust gonads. Their testicles and ovaries hadn’t shrunk, unlike those of sedentary elderly mice.

Dr. Tarnopolsky’s students were impressed. “I think they all exercise now,” he said.

(I’m renewing my gym membership as we speak.)

For those of you who like science-speak, here’s the nut graf from the abstract:

Here we show that 5 mo of endurance exercise induced systemic mitochondrial biogenesis, prevented mtDNA depletion and mutations, increased mitochondrial oxidative capacity and respiratory chain assembly, restored mitochondrial morphology, and blunted pathological levels of apoptosis in multiple tissues of mtDNA mutator mice.

These adaptations conferred complete phenotypic protection, reduced multisystem pathology, and prevented premature mortality in these mice. The systemic mitochondrial rejuvenation through endurance exercise promises to be an effective therapeutic approach to mitigating mitochondrial dysfunction in aging and related comorbidities.

You can see the full report here.

U.S. Solar Manufacturers: The Good, The Bad and The Out of Business

Shyam Mehta of Greentech Media covers some interesting ground trying to answer the question, Is U.S. solar PV manufacturing doomed to failure?

Mehta starts by noting that Evergreen Solar, a Massachusetts-based maker of solar panels, in January announced plans to close its manufacturing facility in Devens, MA, and layoff 800 of its 925 employees. He then cites two other recent prominent solar PV plant closures in the U.S. — BP Solar’s and Sepctrawatt’s — to highlight what doesn’t work when it comes to solar-panel manufacturing.

To paraphrase, if it costs you more to make run-of-the-mill solar panels than it does your Chinese competitor, you should be surprised why your U.S. facility hasn’t been shuttered already.

Solar panels made in China are cheaper than solar panels made in America.

What might work?

Located far away from all the doom-and-gloom pronouncements about domestic PV manufacturing is a large factory in Perrysburg, Ohio that manufactures CdTe modules. It is owned by First Solar, and by all accounts, is doing rather well: it produced an estimated 206 MW in 2010 at below 90 cents a watt, which at its current efficiency (11.6%), is extremely competitive.

How can this be?

First Solar’s technology is low cost (even penalizing it for its lower efficiency relative to c-Si), but it’s also proprietary; it has designed and assembled its own equipment and developed its own process flow, and so far, the Chinese have been unable to duplicate it with any degree of success. Of course, First Solar’s modules would certainly be cheaper if they were manufactured in China: indeed, the U.S.-made modules cost about 10 cents a watt more than those produced at First Solar’s gigawatt-scale fab in Malaysia, another low-cost location. But the Ohio plant is competitive today, and that’s the point; just because the modules could be produced for a slightly lower cost elsewhere is not in and of itself a reason to close a plant. ..

The moral of the First Solar story is that for a domestic facility to succeed in today’s global market, the technology it deploys must be both low (delivered) cost and proprietary.

Mehta then cruises through standard strategies — what could work — for promoting in-country manufacturing. He cites incentives and protectionism before landing on what I think continues to be the most compelling question when it comes to matters of U.S. manufacturing: do we really even need it to work?

[W]hy should we be so hell-bent on preserving American solar manufacturing in the first place? Does it have anything to do with the actual generation of solar electricity in this country? Not in the slightest. Could it be energy security? Comparisons with oil don’t really cut it; we procure 85% of our electricity needs from coal, natural gas, and nuclear, most of which is sourced domestically, so there is no pressing concern here. Is it jobs? A module assembly plant creates roughly 1.5 jobs per megawatt; hardly the panacea for our unemployment woes. Meanwhile, installations create three times as many jobs, and this is work that cannot be outsourced. But a factory with moving parts, permanent “green” jobs (few as they may be), cranking out thousands of pretty panels a day seems a lot sexier than a rooftop installation on a Walmart store that is silently producing clean electrons. What seems to be the case is that manufacturing is held up as some sort of status symbol, both in the minds of politicians and the public, partly because it is tangible, and partly on account of nostalgia for a bygone era.

For what it’s worth, I’m a firm believer in renewable energy and American jobs. From what I’ve read, however, I just don’t see how manufacturing solar panels — which is a relatively capital/input-intensive, labor-light process — can be the single stone that kills two birds, at least from a total number of employed standpoint. Doing energy efficiency and weatherization retrofits? Sure. Installing solar panels? You bet. Maintaining wind turbine farms? It can’t hurt. But even America’s leading solar manufacturers — First Solar and SunPower — realize that some manufacturing activities are most cost-effective when done overseas.

Related: check out Daniel Ikenson’s mini-rant on why he’s boycotting ABC News and Disney to better understand some common misconceptions about manufacturing in America. Spoiler: we’re more efficient and more high-tech than ever, but the percentage of our workforce in the manufacturing has been in steady decline since the 1970s.

MIT Tech Review Digitizes Back Issues to 1969

My parents in their basement have six or seven cardboard boxes filled with back issues of Bon Appétit magazine. While visiting over Christmas, I unabashedly pored over super retro recipes and campy, 1960s-era technicolor ads.

MIT Technology Review cover

What’s more entertaining than poking fun at fondue and bellbottoms? Probably nothing. But a close second is taking a look back at how America’s biggest brains used to think about technology. Especially in an era of cold wars, oil embargoes and regular trips to the moon.

Thankfully, MIT Technology Review has published as PDFs all its back issues to 1969. Subscribers get full access, while everyone else gets the covers and a ten-page preview. Not only is the rag the authority on the future of technology; it now seems to have reasonable claim to the tagline, “the authority on technology’s past.” Haughty MITers…

Point of mild irony: the topics listed in the “in this issue” section above could just have easily come from the latest issue.

Oil Heading to $200 a Barrel?

More and more options traders are betting on higher oil prices, judging by Bloomberg’s chart of the day:

Oil futures on the riseThis is open interest, or the number of outstanding contracts, for call options allowing the holder to buy New York crude for June delivery at $200 a barrel. Events in Libya, where oil production has been cut by anywhere from half to three-quarters, appear likely to drag on. But, according to those interviewed for the Bloomberg article, it’s really the calls for a “Day of Rage” in Saudi Arabia that have traders spooked.

Receiving far less press is the fact that Iraq’s oil exports are the highest since the 2003 invasion, averaging 2.2 million barrels per day in February.

Members of OPEC, meanwhile, are cool as a cucumber:

“There is no need for nervousness…[Oil] supply and stocks are at comfortable levels,” Qatar’s oil minister Mohammed Al Sada told reporters Monday.

Protests Messy, Democracy Messier

My friend and former colleague Haley Edwards is doing a bang-up job reporting from Yemen. (And I, if I do say so myself, am doing a bang-up job reporting on her reporting. From my couch.)

Yemeni protestors

Photo cred: Haley Edwards

Here’s a snippet from her latest story for the L.A. Times:

The radical Yemeni feminist has almost nothing in common with the Islamic tribal sheik, except for a willingness to die for the same cause.

“I’d rather get shot on the street than live under Saleh,” said Sarah, a fiery 23-year-old college graduate and social worker, referring to Yemen’s longtime president, Ali Abdullah Saleh.

Nasser Saber, a 27-year-old sheik from impoverished Marib province, where electricity is a luxury and female literacy is almost unheard of, spoke in similar terms. “Saleh must leave,” he said. “We are ready to give our blood for our freedom.”

Sarah, who asked that only her first name be used for fear of reprisals, imagines overthrowing Saleh and replacing his government with a secular, pluralistic democracy. But with a tiny middle class, virtually no civil society and a very small band of educated youths — the engine behind other Arab revolutions — Yemen, most observers think, is more likely to turn toward Saber’s vision.

Saber, whose life centers on conservative Islam and tribal traditions, wants a government that can deliver services and prosperity to his people rooted in Sharia, or Islamic law.

The dissimilarities between these two equally passionate protesters underscore the central tension at play within demonstrations against the ruler of more than three decades, who has been meeting this week with key opposition figures to discuss their five-point plan on the future of his embattled government. The opposition wants Saleh to resign, but a government statement released Friday said the president had not accepted any such demand.

On Tuesday’s “day of rage,” students, Islamists, socialists and sheiks joined in massive, carnival-like demonstrations in Sana, the capital, where toothless tribesmen with daggers slung around their waists danced alongside college students in graphic T-shirts and jeans. A radical sheik and a human rights lawyer took turns beseeching crowds to imagine the future of Yemen, their crackling visions light-years apart.

If this awkward alliance of adversaries succeeds in overthrowing the president, “then it will be ugly,” Sarah said. “We are fighting for democracy beside people who don’t have any interest in democracy.”

Check out more of Ms. Edwards’ missives from Sana’a at The Haley Bureau.

Mobile Banking in Afghanistan: I Can Hear You, But I Won’t Send You Cash

Jan Chipchase, of frog design, has some pretty incredible pictures and insights into the world of mobile money in Afghanistan.

Like money in the bank
In 2010, the former Nokia design specialist and his research partner Panthea Lee, led a local team to investigate how cell phones are being used for mobile banking in Afghanistan.

At the outset, they expected to find lots of Afghanis using their mobile phones to do their banking. With limited banking infrastructure and rising mobile penetration, Afghanistan is just the kind of place where mobile banking would offer a “safer, cheaper, more convenient way of transferring money … that removes the likelihood of graft.”

What they found was that mobile banking isn’t particularly popular. Chipchase cited a number of obstacles to wider adoption, including:

textual, mobile, and financial illiteracy; a general distrust of institutions compounded by the well-established Hawala agent network; a general distrust of non-tangible assets; and the chicken & egg challenge of investing in an agent network without sufficient customers—customers less willing to experiment with the service without there being a strong agent network.

From what I’ve read, I know mobile banking is all the rage in parts of Latin America, especially Brazil (via Banco do Brasil). It would seem the Afghanistan market, however, has further to go.

If you’re even a little bit interested in mobile money, I recommend moseying on over to Chipchase’s blog and taking a look.

Charlie Sheen Should Write for the New Yorker

Crazy Charlie Sheen quotes + New Yorker cartoons = hilarious.

See more for yourself, courtesy of Matt Stopera. His work obviously begs the question, What other outrageous celebrity antics/tirades/meltdowns could be similarly repurposed for hilarious ends? Developing…

UPDATE: Sheen has apparently broken a Twitter speed record by going from zero followers to over one million in just 24 hours. What a force.
