Fast-charge plugs do not fit all electric cars

A driver looking to quickly charge an electric vehicle can’t necessarily plug into the closest fast-charging station.

Many won’t fit the car.

While automakers have agreed on uniform plug standards for slower types of charging used at home and work, they have not done so for what’s known as DC fast charging, which can fill a battery in less than 30 minutes.

German and American automakers use different connection standards from Japanese and other Asian manufacturers, while Tesla Motors Inc. uses its own system entirely.

Critics say the disparities hinder widespread adoption of electric vehicles, complicating plugging in.

“It’s like if you could only get gas for your Subaru at Sunoco stations and nowhere else,” said clean transportation advocate Chelsea Sexton. “Who would buy that car?”

Yet automakers say they have no interest in developing uniform charging standards and dismiss the implication that different plugs could be slowing sector growth. Instead, many are racing to build out fast-charging infrastructure that fits their cars before new models are released in 2018.

Army’s eco-friendly quest breeds more deadly bullet

The Army set out to develop lead-free bullets to protect the environment. The finished product achieved that goal — and produced the most lethal rifle round to date.For the past five years, U.S. soldiers in Iraq and Afghanistan have been firing eco-friendly rifle bullets with greater ability to pierce protective shields and cause more bodily harm than the lead bullets they replaced.”What started as a program to be more environmentally friendly became a significant upgrade in military small arms capability,” Col. Glenn Dean, who helped develop the green bullet, wrote in his e-book on the experience, “In Search of Lethality.”Those at the Army’s Picatinny Arsenal don’t like to describe one bullet as more lethal than another.”You don’t want to get hit by either bullet,” said small-caliber ammunition project manager Lt. Col. Todd Masternak of the Army’s first green rifle round and its lead predecessor. “If you get hit by one or you get hit by the other and you don’t receive timely medical treatment, you are just as dead.”

Instead, the development team at Picatinny says the green bullet is “more effective” than the lead version.

In layman’s terms, that means the bullet causes more damage to its targets, ultimately incapacitating them — and killing them — faster.

“You can’t kill someone more, but you can become more consistent at incapacitating them,” Masternak said.

When the Army’s green ammunition program began in the late 1990s, it was not designed to create better bullets, just ones that would not contaminate the service’s 3,000 domestic firing ranges.

But creating a lead-free replica of the M855 rifle round proved difficult. The most successful attempt by Picatinny Arsenal used a tungsten-nylon blend. The ammunition ultimately had to be discontinued when troops discovered it sometimes flew sideways into targets with minimal impact.

By 2003, the Army was no closer to a permanent substitute when the War on Terror expanded into Iraq.

That’s when the Army began hearing reports that the lead rifle bullet, which had been used for three decades, was also not always performing as it should. Sometimes it would go right through targets without stopping them; other times it would cause large muzzle flashes as it exited the M4 rifle, temporarily blinding soldiers as they fought.

It was at that point that the “green ammo” mission was turned on its head.

Instead of simply reworking ingredients to create an eco-friendly replica of the M855 bullet, the Army would use green ammo program funding to develop a more lethal bullet that didn’t include lead.

Dean, who declined to comment beyond what he wrote in his e-book, recalls a 2005 meeting about the M855’s shortcomings when the green ammunition program came up.

“The program leads and contractors were laying out the scope of that effort when an infantry representative spoke up and said, basically, ‘Look, we’re in the middle of a war. No one gives a shit about being environmentally friendly right now. Can’t you give us something better instead?'” Dean wrote.

The green M855A1 — or enhanced performance round — is the Army’s answer to that question.

Enhanced performance

Made of a copper slug and steel penetrator, the round contains lead only in its primer, the part of the cartridge case that ignites gunpowder. The primer burns off when the bullet is fired, and the projectile itself is lead-free.

The technical explanation for the improvements can be gruesome, but it can also mean the difference between life and death for U.S. soldiers on the battlefield.

When a bullet is fired from a gun, it’s supposed to shoot straight. If aimed at a hard target — like a car door or a barricade — an ideal bullet would continue a straight trajectory even upon impact in order to penetrate the barricade and hit whoever is hiding behind it.

Once it hits a “soft target” — the military’s euphemism for human flesh — an ideal bullet would begin to tumble in what’s known as a “yaw,” bouncing off and damaging as many organs as possible in order to incapacitate the enemy.

Picatinny studied the old M855 round extensively when the arsenal decided to reinvent it. It found that, when fired at close range, the bullet didn’t always have time to yaw when it hit a person, particularly a thinner one. Instead, it went straight through the person.

“In essence, all of the anecdotal evidence was correct — the M855 could be highly lethal or highly ineffective depending on circumstances which the user could not control,” Dean wrote.

The challenge in developing the new, more effective “green ammo” was to keep the bullet’s same target-penetrating power while making sure its trajectory would destabilize upon hitting flesh.

Distributed to troops in 2010, the M855A1 is better at both tasks.

The green bullet can penetrate a 3/8-inch-thick steel barrier at twice the distance the old lead round can, according to Picatinny. It can also penetrate concrete masonry from up to 100 meters away, something the lead bullet could not do at any range.

The more than 1.5 million green bullets fired in testing consistently hit soft targets — using gelatin as a stand-in for flesh — without creating through-and-through wounds and also penetrated Kevlar body armor fabric from more than 1,000 meters away.

“In other words, the A1 will stop the enemy quicker so he cannot fire back,” Masternak said.

The upshot

Exactly who redesigned the green bullet is in dispute. In 2011, the Department of Defense was sued by Liberty Ammunition, claiming the enhanced performance round was developed using technology patented by the Florida-based company.

U.S. Federal Court of Claims Judge Charles Lettow ruled in favor of Liberty this winter, writing that the government had infringed on a patent Liberty applied for in 2005 and received in 2010. He ordered the government to pay a $15.6 million lump payment as well as a 1.4-cent royalty on every bullet purchased until the Liberty patent expires in 2027.

The Army and Department of Justice declined to comment. In its appeal, the government argues that though Liberty met with the Army and gave it sample bullets, those samples were never tested and differed significantly from the bullet the Army says it ultimately developed with a different contractor.

Within the military, not everyone has been as enthusiastic about the M855A1 as the Army. While the Air Force and National Guard also use the bullet, the Marine Corps continues to field the old leaded M855 while developing its own lead-free alternative.

That’s mainly due to concerns about whether the new bullets do more damage than lead bullets to rifles, said Col. Michael Manning, who manages infantry weapons systems for the Marine Corps. Initial testing in 2009 found that the M855A1’s steel penetrator was “chewing up” some magazines, expediting the usual wear and tear expected in military equipment.

The Army said its tests did find that the green bullet causes a rifle to “wear differently” and that the hardened penetrator can create marks on a rifle muzzle. But the Army said that issue does not affect the M855A1’s performance. Since developing the enhanced performance round, the Army has also developed an “enhanced performance magazine” to eliminate those issues.

The Marine Corps is re-evaluating the green round, and Manning made it clear that his concerns about the Army’s green ammunition had nothing to do with its ability to hit and incapacitate a target.

“There is no question that the M855A1 does perform better than the M855,” which the Marines still use, he said. “We vehemently agree with the Army that the M855A1 is better.”

For its part, the Army has continued its quest to get the lead out. Since fielding the original green bullet, Picatinny Arsenal has developed many more types of lead-free rounds, including those used by snipers and in medium-sized machine guns.

In November 2014, the Army issued two more types of green bullets to troops. As with the M855A1, tests show each new bullet outperforming its lead predecessor.

“What we’ve done is remove the lead from production, removed the lead from the training ranges, while providing the Army with a more capable, more consistent ammunition round,” Masternak said. “The fact is that we can meet our mission needs while removing the hazardous materials the Army was built on.”

Offshore Wind: After building it, one city wonders if they will come

NEW BEDFORD, Mass. — The ocean has been good to New Bedford.

This coastal Massachusetts city was once one of the richest in the world thanks to a booming whaling industry, serving as a home base for mariners searching for fortunes in whale oil.

That was in the 1850s, when in his novel “Moby-Dick,” Herman Melville described the city with its “opulent” homes and gardens as “the dearest place to live in all New England.”

It’s not like that anymore.

The city of 100,000 has been in decline ever since whaling’s demise. Manufacturing initially replaced whaling as the top industry, but those jobs have since been outsourced, leaving behind a dozen abandoned mills sitting on useless, contaminated land. Now New Bedford’s economy is led by its commercial fishing fleet, which is more often than not in port thanks to federal quotas. Today, the former homes of whaling captains sit dilapidated, divvied up as multifamily rentals.

New Bedford is in need of a renaissance. To bring it, officials are looking to the sea once again in an attempt to reinvent the city as a hub of the offshore wind industry.

It’s a risky strategy.

With no active offshore wind farms in the United States, the industry is in its infancy. And Cape Wind, which is set to be the city’s first offshore wind customer, has been dealt blow after blow this month with the loss of two power purchase agreements and a suspension from participating in New England’s wholesale energy markets. The prospect of other projects getting steel in water anytime soon also seems more unlikely this year with the expiration of federal renewable energy tax credits.

But Massachusetts has spent $113 million on a new port facility in New Bedford built specifically to cater to offshore wind farms, bolstering widespread community support for the strategy. The city’s location near two federal areas off the coasts of Massachusetts and Rhode Island slated for wind development also buoys residents’ hopes.

Says Mayor Jon Mitchell: “The arrival of the offshore wind industry in America, and especially the Northeast, is inevitable. And when it comes, New Bedford will be ready.”

Funding cuts, EPA cleanups and the toxins left behind

Trout caught in Torch Lake, Mich., are not safe to eat. Groundwater in Baldwin, Fla., is not safe to drink. Six acres of land in Bridgewater, Mass., are not safe to live on.

All three locations were once among the most dangerous toxic waste sites in the country and became part of the Environmental Protection Agency’s Superfund cleanup program. All three are now considered clean by the EPA, though toxins remain.

The EPA is responsible for protecting human health at 1,700 hazardous waste sites across the country through the Superfund program. These sites contain chemicals that can cause a range of serious illnesses, from cancer to birth defects to neurological disorders.

As is the case at Torch Lake, Baldwin and Bridgewater, an EPA “cleanup” does not mean all toxins are gone. Toxic materials, in many cases, are physically or financially impossible to eliminate. Instead, many Superfund cleanups end with restrictions on how a site can be used because the toxins left behind still pose a danger to human health.

But as time passes after a cleanup, no one agency monitors adherence to the restrictions. And notice or awareness of the restrictions fade or fail to remain part of property records. Ultimately, potential dangers remain for the one in four Americans who live within four miles of a Superfund site.

Federal funding for Superfund cleanups has stagnated over the past 15 years, even as the number of Superfund sites grows. Critics worry that financial constraints will only increase the amount of toxins left behind after Superfund cleanups, putting residents at risk. Continue reading
