Crash-test dummies are getting fatter, too

A major manufacturer of crash-test dummies is redoing its line to "represent thicker waistlines and large rear ends of Americans. The new model of Humanetics has been developed after studies found that 78% of obese drivers are more likely to die in a car crash."

So reports a site called Uncover Michigan in this story about the firm Humanetics.

Dummies have traditionally been modeled on a person weighing about 167 pounds with a healthy body mass index (BMI). ...The new super-sized dummies are based on the measurements of a 273-pound person with a BMI of 35.... An obese person has more mass around midsection and a larger rear which pushes them out of position. They sit further forward and the belt does not grasp the pelvis as easily.

In other news, scores of people camped out in Nashua overnight to get a chance at some free fast-food chicken. No, really.

In Maine, a two-headed snapping turtle is thriving, and eating with both heads

The Bangor Daily News reports today:

A two-headed snapping turtle found on Sept. 22 is still alive and eating from both heads, thanks to Kathleen Talbot, who has been caring for the unusual reptile since discovering it by the road near her home.

“I’m amazed. I really didn’t expect him to live this long,” said Talbot, who came across the tiny turtle while walking along Route 43.

I'm sure there's some two-heads joke to make about politicians at this point. But man, I'm sick of politics.

Nashua to install electric-car charging station at city garage

gg1029nashuaelectriccar

Phil Plourde of the city of Nashua demonstrates the new car-charging station in the Elm Street public parking garage.

The slow spread of electric-car charging stations in New Hampshire has reached Nashua, with Wednesday’s opening of the first city-overseen unit in the Elm Street parking garage.

The charger is a 240-volt system that can “fill up” an empty electric car battery in about eight hours, depending on the model, adding 10 to 20 miles of range each hour. It was turned on Wednesday morning, and formally unveiled in an afternoon ceremony featuring Mayor Donnalee Lozeau and officials from PSNH, which paid for the roughly $2,400 installation of the system.

For the time being the electricity is free – cars will pay the same rate of 50 cents per hour as in other parking spots in the garage. Eventually the space will cost extra, although the difference is still being determined.

“It’ll take legislation to change the rate. We’re gathering data and will present it to (the mayor and aldermen),” said Community Development Director Sarah Marchant.

On Wednesday morning at the garage, parking maintenance worker Phil Plourde demonstrated the unit, made by a company called AeroVironment. It has a simple on-off button and a nozzle that plugs into the charge port of electric cars.

Drivers who park in the space use the charger must type the parking space’s location number into the city’s pay station to activate the system.

Plourde said he liked the idea of electric cars but, like many people, was concerned about the lack of places to charge up. He thought the city’s charger was the sort of action that might change minds.

“Once people get used to seeing it, they’ll be more open. The more stations there are, the better,” he said.

This charger is the city’s first publicly accessible charging station that isn’t hosted by a car dealership. Peters Nissan, which sell the Leaf, the world’s most popular electric car, and Tully BMW, which sells the electric I3, have stations.

A number of private, at-home charging stations also exist in the area, installed by people who bought electric cars or plug-in electric hybrids like the Chevy Volt and Toyota Prius. Some of those stations can be used by others with permission: The website Plugshare.com lists three such homes in Nashua, plus several others in neighboring towns.

Public electric-vehicle charging stations exist at the Bedford Village Inn and at the Tyngsborough, Mass., library, and the upgraded Hooksett toll plaza on I-93 will have 10 charging stations when it is completed. Simon Properties, which owns the Pheasant Lane Mall and many other malls in the state, has begun installing charging stations at some of its properties nationwide, although no announcement has been made in New Hampshire.

Portsmouth installed a similar charging station in its city parking garage this year. Marchant said Nashua has been talking to that city about its experience, as it prepares for its charging station.

Tesla, the luxury electric sports car, said it plans to install one of its “supercharger” stations on the Seacoast this year, although it hasn’t said where. It would probably be near I-95.

Superchargers, which require a 480-volt electrical connection, charge vehicle batteries at 10 to 15 times the rate of a Level 2 charger. They require a special connection port only available on a Tesla, although the company is sharing its technology so that other cans can take advantage of them.

The charger installed in Nashua and at most other locations is a so-called Level 2 charger, which operates at 240 volts. It is also possible to charge an electric car from a wall socket with a Level 1 system, but that generally takes more than a day to fully charge a vehicle.

The Nashua charging port was installed on the lower level of the Elm Street Parking garage, next to the Transit Center, in a space that is often empty, said Marchant.

“It’s not an electric-car-only space, but it hasn’t been use heavily in the past,” she said.

The charger will be available between the hours of 6 a.m. and 11 p.m., when parking charges within the garage are enforced. No electricity will be produced when plugging in overnight, before 6 a.m.

All of these factors may be changed as Nashua learns more about how to operate the system, Marchant said.

PSNH has also helped create Level 2 electric vehicle charging stations at Antioch University New England in Keene and Redhook Brewery in Portsmouth, and plans two more around the state. It also has a system at its Manchester headquarters, for PSNH employees.

NHBR: Papers show GTAT bit off more than it could (probably) chew with Apple contract

gg1028gtat

The cover of an industry brochure from GT Advanced Technologies shows large opaque cylinders made of synthetic sapphire. Building furnaces to grow such crystals and creating and shaping the crystals themselves is GTAT's business.

New Hampshire Business Review (which mostly calls itself NHBR these days, much to the confusion of NH Public Radio fans) has been all over the bankruptcy of GT Advanced Technologies in Merrimack. Their latest story details how the high-flying company imploded:

GTT Advanced Technologies’ original deal with Apple, signed last Halloween, mandated that the Merrimack-based company install 2,036 sapphire furnaces by April 2014, indicating that the product that was supposed to be produced in those furnaces was intended for the touchscreens of its new iPhone 6 after all. But Apple’s decision to only use the sapphire in its new Watch sharply reduced its demand and resulted in the tech giant withholding a $139 million prepayment. The result was GTAT’s Oct. 6 bankruptcy filing.

You can read the whole thing here, including commentary on how such a massive contract - the furnaces are large and expensive - was a very, very risky plunge for a relatively small firm.

The first banner ad graced (so to speak) web browsers 20 years ago today

I'm not getting paid to run this.

The first web banner ad ran 20 years ago today, on Wired.com - from AT&T.

I know what you think of banner ads - but as somebody whose paycheck depends on the ever-shrinking advertising world, I wish they worked better!

Will at-home screening for colon cancer increase false positives and unnecessary treatment?

A new test that looks for cancer-related DNA in human stool (the bodily fluid, not the furniture) is raising the bar on the debate about how much medical screening is too much. AP story is here.

By coincidence, the question of how much screening is too much will be discussed Nov. 19 at the next Science Cafe New Hampshire in Nashua. Dr. Jose Montero who heads the state's public health division, will be one panelist.

The question is whether a home cancer-screening test will help or hurt public health. Advance screening is a good thing if it spots problems before they become serious; it's a bad thing if it causes unnecessary alarm through false positive results or even causes unnecessary treatment. Concern about that last point led the U.S. Preventive Task Force to cut back on its prostate-cancer-screening recommendations for adult males - a change that has drawn considerable disagreement.

Any story with a question-mark headline should, according to conventional wisdom, be answerable with a "no," but that's not the case here. It's not at all clear that putting cancern tests in the hands of untrained patients will do more good than harm.

Air temperature? If you're de-icing roads, you really care about pavement temperature

gg1023deicing

New Hampshire held its first-ever Salt Symposium on Wednesday for private contractors that apply salt to keep parking lots, driveways and sidewalks clear, siging them up for voluntary certification program and discussing research about best practices. I would have attended but had to cover a political event - bleahhh - so I'm doing a follow-up story.

One of the issues with deicing, I have learned, is that icing applications change due to air temperature, but what *really* matters is pavement temperature, which can differ from the air by as much as 8 or 9 degrees Fahrenheit. That temperature determines whether the sodium chloride will turn to brine, as is needed to melt ice, and therefore determines how much salt you should apply.

Turns out, infrared thermometers exist that can be attached to the outside of a plowtruck to measure the temperature of the pavement ahead, with readouts in the cab. Cool!

There's no real change in the chemistry of de-icing salt, but there is a recent legal change: A new state law gives liability protection to private plowtrucks if there's an accident after they salt a location. It is based on the law which provides liability protection for ski areas.

Don't expect to see much, if anything, of tomorrow night's partial solar eclipse 

bb1022solareclipse

This screenshot from an animation created by NASA shows that the shadow of the moon moving across the Earth during Thursday's partial solar eclipse will be visible in this area just as the sun sets, as shown by the shadowed half of the globe.

Even if clouds don't get in the way, we probably won't see much if anything of Thursday's partial solar eclipse, because it will occur just as the sun sets in southern New Hampshire.

I grabbed a screen shot of an excellent GIF animation from NASA, spotted via Bad Astronomy on Slate, showing the sunset shadow moving down toward us as the eclipse shadow moves east toward us. It's hard to see exactly, but it looks like we will miss it.

If you can get high up enough to see over obstacles to the west - maybe climb a fire tower - you'll probably only see the smallest sliver of moon cut into the sun.

Better luck next time. Which will be Aug 21, 2017, according to an eclipse calculator that I found. But that should be a good: We'll be right in the middle of a long, full solar eclipse.

NH will finally get (probably) a multi-megawatt solar farm

A developer has gotten thumbs up from the Manchester City Council to put a 3.2-megawatt solar farm atop the long-closed city landfill, the Union-Leader reports. (PSNH considered doing something similar years ago - closed landfills are common sites for solar farms.)

Financing still need to be completed; construction might begin next year. If so, it would be the first multi-megawatt solar facility in New Hampshire, although a 1-megawatt farm is being built at the Peterborough Wastewater Treatment Facility.

The dump is right next to I-293; you've probably noticed the methane pipes sticking out of the ground as you drive past. That leads to a question, as the story noted:

Ward 12 Alderman Keith Hirschmann asked about the possibility of solar glare, particularly for drivers on I-293. Ouimet said drivers going north would not be able to see the panels and southbound drivers would only see the back of the installation. He added that the panels are designed to be “anti-glare.” Due to glare problems, the solar array at the Manchester airport had to be repositioned earlier this year at a cost of $1.9 million.

No NH cities are part of push for municipal fiber-to-the-home broadband 

gg1001gigabitcities

No New Hampshire cities are among the 32 who have signed up to push for their own gigabit Net connections as part of a program called Next Century Cities, which launched this week.

The project is basically an attempt to help cities organize for municipal fiber-to-the-home, out of concern that local cable/phone providers are never going to do it. It's collaboration, not funding. From the website:

The caliber of Internet networks required for cities to compete, grow, and thrive in the 21st century will largely not be achieved through the copper wire networks of the 20th century. Cities and their leaders recognize that the present and the future will be based on fiber-optic, gigabit networks that can deliver speeds at hundreds of times the current national average.

There are also outside factors that impact the ability for cities to succeed. Towns and communities struggle with limited budgets, laws that restrict their opportunity to build/support a network that fits their needs, and even market pressures.

No New Hampshire or Vermont cities are among those who are participating so far. Boston and Portland, Maine, have signed up, as have tiny Leverett, Mass. (population 2,000, out in the Berkshires) and small coastal Rockport, Maine, which has built a mile of still-dark fiber to serve Maine Media College and its downtown, and wants to do more.
