Recently Kimball posted a moving and fascinating personal log of sailing aboard the US Coast Guard 295-ft sail training ship EAGLE.
(…) Throughout our three-day passage from Portland to the Golden Gate, the ship received visits from service helicopters and cutters, all eyes out to see the Eagle. Their Eagle. I began to get it. What’s hard to put into words. Eagle is magic.
On our last day out the wind piped up and the old girl was hauling the mail . . .

We greatly enjoy Kimball’s writing. This piece is a wonderful example, which Kimball has annotated with a number of his original photos.
(…) Through the Coast Guard Foundation, I met remarkable people. One of them was Lieutenant Commander (soon to be promoted) Alda Seabrands. She was called in for the shouting at a Foundation fundraiser.
Alda had been flying a pollution patrol over Puget Sound (meaning, no rescue jumper), when her helicopter was diverted to SAR. A fishing skiff had capsized, spilling two people into white water. The chopper made the scene quickly, dropped a basket, and one man climbed in. He was hauled aboard and the basket lowered again. The second man put one arm over the edge of the basket, then rolled unconscious. Alda told her copilot, “It’s all yours, Binky.”
OK, she didn’t exactly say that, and I’m sure the events, however dire and hurried, were more complicated. But Alda Seabrands was flying as Pilot In Command when she, in full awareness, left her post. As a certain Admiral put it to me, “We had to decide whether it was a court-martial or a medal. We decided it was a medal.”
Just don’t miss it – get on over there.
Physical chemist and entrepreneur John Morgan wrote a fascinating post for Brave New Climate in January. The possibilities of the US Navy and Palo Alto Research Center (PARC) research underscore the importance of innovation to deliver energy and especially transport fuel solutions that are workable (i.e., solutions that are compatible with Roger Pielke’s Iron Law).
The seawater CO2 extraction is a big win if the costs hold at scale, because the costs look to be MUCH lower than direct air capture. If the huge energy inputs required are supplied by nuclear (especially if the nuclear supply includes 800C process heat via high temperature gas reactor), then the synfuel is long-term carbon neutral. Innovation in direct air capture is still extremely important because it is clear that the planet will greatly exceed current carbon goals before it becomes truly zero carbon.
Two papers published last year described a new approach to zero emissions synfuel, looking at direct carbon dioxide extraction from seawater. The new insight in these papers is that CO2 is very soluble in seawater, where the concentration is about 140 times higher than in the atmosphere. This could make seawater extraction a lot cheaper than direct air capture.
Please read John’s entire post – it is well-sourced and well-written, and I believe accurate.
NASA has been researching Blended Wing Body (BWB) aircraft, building a series of larger and larger remote controlled experimental planes. NASA has recently announced a carbon-composite based manufacturing process that they think will enable production of sufficiently strong structures for commercial use.
Wikipedia on BWB: aircraft have a flattened and airfoil shaped body, which produces most of the lift, the wings contributing the balance. The body form is composed of distinct and separate wing structures, though the wings are smoothly blended into the body. By way of contrast, flying wing designs are defined as a tailless fixed-wing aircraft which has no definite fuselage, with most of the crew, payload and equipment being housed inside the main wing structure.
A blended wing body has lift-to-drag ratio 50% greater than a conventional airplane. Thus BWB incorporates design features from both a futuristic fuselage and flying wing design. (…)
I’ve not yet found any drawings of the proposed composite construction – but Kevin Bullis at MIT Technology Review has this:
The second challenge is building a full-scale version of the aircraft with pressurized cabins that is structurally sound. One reason tubular airplanes have persisted is that it’s relatively easy to build a tube that can withstand the forces acting on it from the outside during flight while maintaining cabin pressure. The hybrid wing design involves a flatter, box-like fuselage that blends with the wings. The flatter structure, which includes some near-right angles, is much more difficult to build in a way that’s strong enough and light enough to be practical.
NASA’s manufacturing process starts with preformed carbon composite rods. The rods are covered with carbon fiber fabric and stitched into place. Fabric is then stitched over foam strips to create cross members. The fabric is impregnated with an epoxy to create a rigid composite structure.
Sections of a fuselage built with the technique were tested and shown to withstand up to the forces that would be applied to a finished aircraft. Tests also showed that when enough pressure was applied to cause the parts to fail, the stitching used to make the structure stopped cracks from spreading—a key to avoiding catastrophic failure in flight.
I sure agree with Dave Winer: Thread: A smartphone narrative and an idea for a product. Following is an excerpt of his proposal:
(…) Now finally I’m able to explain the idea.
When I tried to send text messages from my desktop Mac, all of a sudden I was dropped into a horribly complex maze of things that make no sense. I can’t even figure out how to send an SMS without someone sending me one first. I tried reading all of Google’s docs, installed all the software they told me to install, and in the end I went back to the Nexus 4 to communicate with Jen. Later I realized I could do what I needed to with the Voice website. But there were problems there too. I ended up having to enter the number manually, my contacts list was useless in that context.
The idea is this — Google or Microsoft or Apple — create a new app that runs on the desktop that’s designed with the parameters of a smartphone. Leverage the skills I already have. I was able to set up the Windows Phone in a few minutes, on an OS that I had never used. I am a relatively expert Mac user, but failed after a half hour. The lesson is pretty clear. At the very least the desktop has to do what the mobile device does, with the same care of design and simplicity. What I’m left with is a hodgepodge of stuff that wasn’t designed to do this. Time for a fresh look.
We are often frustrated by the same issue. Our solution is the web-based international service ipipi.com at the reasonable cost of $ 0.10 per message.
Architect Kent Larson is the director of Changing Places at the MIT Media Lab. Larson, postdocs and students are innovating a large number of ideas of how the urban future can be happier, less stressful, wealthier and low-carbon. Some of these concepts like the City Car, or self-driving cars, we’ve written about before.
At TEDx Boston 2012 Kent gave an 18 minute presentation. I’m confident you’ll be thinking of more ideas that will contribute to better city life for the hundreds of millions of rural people who will be migrating to cities over the next two decades (300+ million in China alone).
I’m a fan of the Uber startup. For a running expose of the corrupt Washington DC politics, there is no better source than Megan McArdle:
As I chronicled in the Atlantic six months ago, upstart limo dispatch service Uber is embroiled in a long-running war with the DC taxi commission. Uber allows you to order a sedan service from your smartphone, and is much beloved by affluent DC DINKs. It is also a favorite of the limo drivers, who like being able to get rides at good pay rates, and without paying kickbacks to the dispatchers. A couple of nights ago, I took an Uber to a work event (you still can’t reliably get a cab in my neighborhood), and the driver told me that he’d just bought the shiny new Lincoln he was driving to strike out on his own. Uber is what made that happen, according to him; under the old system, it was hard for drivers to go solo, because there are network effects in black car services-; large services tend to get most of the clients. He was beaming as I inspected his brand new wheels, as proud of that car as if he’d baked it himself.
However, Uber is not beloved of DC taxi drivers. As Bob McNamara of the Institute for Justice told me, “Like any other business, taxi drivers think it would be great if no one could compete with them.” Taxi drivers and owners provided a lot of support for our current Mayor, Vincent Gray, in his hotly contested primary race with former Mayor Adrian Fenty. (They also seem to have offered some illegal support to the city council staff; one member’s former aide got jail time for accepting bribes.) The commission has become quite cosy with the industry incumbents in recent years, to the point of issuing a de-facto moratorium on new taxi and limo licenses. The election did nothing to reverse that relationship.
The taxi commission has been gunning for Uber since last year, when they launched a “sting” featuring Commission head Ron Linton, which ended in the unlucky driver having his car impounded. Originally they said the service was illegal because you couldn’t use a black car to charge for time and distance; when Uber’s supporters pointed out that the taxi code contained a “sedan” designation that seemed to allow black cars to do just that, they suddenly came up with a new rationale: Uber was illegal because it didn’t offer you a paper receipt. I was unable to find an Uber customer who expressed any desire to have a paper receipt, but perhaps they are out there, frantically lobbying the taxi commission.
Joshua Gans examines Uber’s challenge in mediating what customers want and what drivers want. When I first read about Uber’s dynamic pricing I thought that was brilliant – prices will raise until demand is satisfied, the New Years Eve taxi market will clear! Turns out things are more complex. Here’s a snippet:
Over the last year, a new app has been changing the way people get limos in some major cities in the US. Uber — founded by Garrett Camp, Oscar Salazar, and Travis Kalanick, and launched in 2010 in San Francisco — allows people to get and pay for taxi rides easily. Here’s how it works: after you have signed up for an Uber account, you can launch the smart phone app and instantly find limos or town cars equipped with the service. One click hails them, and the nearest driver comes and picks you up. At the end of the journey, your driver charges your account. No standing in the rain trying to hail a cab. No grabbing for cash or fiddling with credit cards.
(…) If this were a one-time mishap, we could set it aside. But sticker shock has actually turned out to be a ongoing issue for the company. This was demonstrated most clearly in New York on New Year’s Eve, a night that should have been a triumph for the start-up. Because of high demand and the accompanying ever-higher prices, Uber’s supposedly simple and straightforward transaction became complex. Consumers saw that their ride home could be seven times the price of their ride into town. Consumers who were used to easy clicking missed the notice and became (reasonably) upset when the bill arrived. Either way, they weren’t happy. Basically, to satisfy one side of its market — the taxi drivers — Uber upset the other side — its customers.
Joshua concludes with some revised pricing schemes that may resolve this challenge. I sure hope it works – Uber is a long-needed breakthrough. More…
This looks plausible, although I’ve not done any homework to verify or calibrate this analysis. We know that such pyramids of layered subsidies are real – here is the Mackinac Center interpretation on the Volt:
Each Chevy Volt sold thus far may have as much as $250,000 in state and federal dollars in incentives behind it – a total of $3 billion altogether, according to an analysis by James Hohman, assistant director of fiscal policy at the Mackinac Center for Public Policy.
Hohman looked at total state and federal assistance offered for the development and production of the Chevy Volt, General Motors’ plug-in hybrid electric vehicle. His analysis included 18 government deals that included loans, rebates, grants and tax credits. The amount of government assistance does not include the fact that General Motors is currently 26 percent owned by the federal government.
The Volt subsidies flow through multiple companies involved in production. The analysis includes adding up the amount of government subsidies via tax credits and direct funding for not only General Motors, but other companies supplying parts for the vehicle. For example, the Department of Energy awarded a $105.9 million grant to the GM Brownstown plant that assembles the batteries. The company was also awarded approximately$106 million for its Hamtramck assembly plant in state credits to retain jobs. The company that supplies the Volt’s batteries, Compact Power, was awarded up to $100 million in refundable battery credits (combination tax breaks and cash subsidies). These are among many of the subsidies and tax credits for the vehicle.
It’s unlikely that all the companies involved in Volt production will ever receive all the $3 billion in incentives, Hohman said, because many of them are linked to meeting various employment and other milestones. But the analysis looks at the total value that has been offered to the Volt in different aspects of production – from the assembly line to the dealerships to the battery manufacturers. Some tax credits and subsidies are offered for periods up to 20 years, though most have a much shorter time frame.
What are the total layered subsidies behind each wind turbine or solar panel?
