Plugin Hybrids even closer

Byoliveridley

I tend to be a bad news blogger, so when some good news comes along, I really should mention it…  A plugin hybrid (PHEV) is a gasoline car with a battery that can be charged. So, you go 30 miles or so on battery power before switching to gasoline, and plug the cars in at night so that they will be ready to go again the next morning. The average American commute is 16 miles (one way), so the amount of gas used for work and back for me will be reduced from around 1.2 gallons (assuming about 28 mpg city for my current car) to around 0.1 gallons. Think about that!

The good thing about these batteries is that they seem to be built with ruggedness (10 year, 150,000 miles) in mind.

The Energy Blog: A123Systems Announces Li-ion Automotive Batteries

A123Systems today introduced its 32-series Nanophosphate™ Lithium Ion cells, specifically designed for Hybrid Electric Vehicle (HEV) and Plug-in Hybrid Electric Vehicle (PHEV) use. These batteries leverage the company’s existing low-cost, high-volume manufacturing techniques to offer the electric drive industry a new level of price-performance.

Hope they work as advertised. My next car is definitely a PHEV.

Meanwhile, America’s most experienced, most accomplished and most sensible presidential candidate gives a truly forward looking speech on energy policy, and nobody notices. I guess he’s just not good looking enough.

Killer nets reinstated

Council Decisions: March 2006

Drift Gillnet Management

The Council adopted a recommendation to NMFS to authorize an exempted fishing permit (EFP) that would allow drift gillnet fishing in the current August 15-November 15 closed area. The EFP fishery would be governed by several requirements for all vessels, including, to carry an observer; to limit total fishing effort in the EFP fishery to 300 sets; to immediately cease the EFP fishery if, and when, two leatherback sea turtles were encountered by the fishing gear; and to immediately cease the EFP fishery if one mortality or serious injury occurred to any of the following marine mammals: short-finned pilot whale, sperm whale, fin whale, gray whale, humpback whale, or minke whale.

And, with that, starts the rather egregious practice of drift gillnet fishing. The restrictions seem fairly tight, an observer on every boat, and end to the fishery after two incidences of capture. There is definitely more than meets the eye here, I don’t know what. Drift gillnet fishing is well documented to cause turtle catch, this from the 1998 Fishery Bulletin for 1990-1995

In the drift gillnet fishery, seven out of 387 mammals observed entangled were released alive. In the set gillnet fishery, five out of 1,263 mammals observed entangled were released alive. Estimates of incidental kill are presented along with estimates of entanglement for species that were observed to be released alive. For the period under consideration, the estimated mortality for the drift gillnet fishery was over 450 marine mammals each year. A total of 20 turtles and 3 seabirds were observed entangled during the entire period. The most frequently entangled species in this fishery were common dolphins, Delphinus spp., and northern elephant seals, Mirounga angustirostris. Estimated cetacean mortality in the driftnet fishery decreased from 650 in 1991 to 417 in 1995; pinniped mortality decreased from 173 in 1991 to 116 in 1995. Estimated cetacean mortality in the set gillnet fishery ranged from a high of 38 in 1991 to a low 14 in 1993; pinniped mortality rose to a high of 4,777 in 1992 and then decreased to 1,016 in 1995. We postulate that there has been a decline in the number of pinnipeds and cetaceans in the setnet fishery owing to area closure. No similar proposal can be made for the driftnet fishery. The most frequently entangled mammals in the setnet fishery were California sea lions, Zalophus californianus, and harbor seals, Phoca vitulina. Six turtles and 1,018 seabirds were estimated entangled in this fishery during the NMFS Observer Program from July 1990 to December 1995.

So what’s the deal, this thing caught 20 turtles in 5 years, so it is going to catch turtles, no doubt about it. Anyone who does not get what the death of one adult sea turtle means read this. Sea turtles are wonderfully fragile animals given their size, they take long to mature sexually, they do not breed all that much and less than 1% of turtle hatchlings survive to adulthood. Leatherbacks are highly endangered.

I have a feeling that this is the first part of a one-two punch intended to reinstate the famed turtle killer long line swordfish nets on the pacific coast. The “proof” that these nets do not catch turtles will be used to lobby for longline swordfishing in, oh say three months?

Most random use of global warming as an excuse

Anaheim council OKs Disney-adjacent housing development – Los Angeles Times

In a new argument Tuesday, Disney officials provided city officials with an inches-thick packet asserting that the residential project would exacerbate global warming because of the traffic it would generate.

It is nice when Disney expresses concern about global warming, but why???

Over the strong objections of Disney and dozens of tourist officials, the Anaheim City Council voted 3-2 early this morning to approve a controversial residential project in the city’s resort district.

The six-hour public hearing, which began Tuesday night and spilled into this morning, was the council’s second attempt to settle the dispute that had lingered for nearly a year.

About 150 resort workers, many from Disney, attended the meeting in support of the development, some wearing stickers that read “Yes in Mickey’s Back Yard” (YIMBY). The dozen employees remaining at the meeting cheered when the project was approved.

Ah, I get it, they don’t want people working at Disney living near Disney!! So, go ahead, use global warming as an excuse! If it were not disgustingly hypocritical, it would be funny.

Nanoparticles the new asbestos?

Byoliveridley

I am sure everyone has heard about the wonders of nanotechnology, but what about the other side?

ScienceDaily: Tiny Inhaled Particles Take Easy Route From Nose To Brain

In a continuing effort to find out if the tiniest airborne particles pose a health risk, University of Rochester Medical Center scientists showed that when rats breathe in nano-sized materials they follow a rapid and efficient pathway from the nasal cavity to several regions of the brain, according to a study in the August issue of Environmental Health Perspectives

There was a time when asbestos was the wonder material, malleable and fire resistant, capable of being woven into sheets, and being incorporated into buildings for fire retardation. Unfortunately, many cases of asbestosis and mesothelioma later, not so wonderful. Asbestos is a special case because the fibers started out big and would keep breaking down into smaller particles till they reached that magic size range between 0.1 and 1-2 um where they could stay suspended in the air for a long time, and also take advantage of the lungs’ inability to filter particles that size to any great degree of efficiency.

Nanoparticles are an order of magnitude smaller, and hence behave more like gases. They may  also contain choice toxic heavy metals such as manganese which are not usually floating around in the air at these small sizes. So, this study is a little scary, especially for the folks in the manufacturing end of things, these miracle particles seem to be going straight to the brain. Traditional masks and air handling systems are not designed to filter such fine particles, so I am sure they’re floating around in the air waiting to be breathed in.

Update 9:00 AM, 8-3-2006
Well, I swear, I did not see this before I wrote this morning!

The question of the day, however, is are they safe for humans and other living things? Earlier this year, Andrew Seaton, A U.K. scientist who was the lead author of a 2004 report investigating the saftey of nanotechnological materials raised a bit of a ruckus by comparing carbon nanotubes to asbestos fibers. Asbestos once had its day in the sun as an all-purpose wonder material. But then we learned that tiny asbestos fibers, once ingested by the human body, could be extremely deadly. Carbon nanotubes: also easy to ingest, and exquisitely capable of penetrating cell structures. Could they be equally toxic?

New York Odor from the Marshes?

Byoliveridley

Turns out that the fugitive emission of nasty sulfur gases in New York that had Fox News suspecting terrorism for a while may have come from more mundane sources.

Sniffing Out the Truth – New York Times

But we haven’t, and we think we can support one of the theories of the odor’s source that has been suggested. Based on our familiarity with the local aquatic environment and regional meteorology, we believe that the odor was caused by gases released from saltwater marshes in the metropolitan area. Let us explain. The intertidal sediments in this region are home to micro-organisms that produce sulfur compounds. When these sediments interact with saltwater that contains low levels of oxygen, gases are released. These gases include hydrogen sulfide and a variety of thiols (like the gas additives thiophane and mercaptan) — all of which have an odor similar to rotten eggs.

First, there was a low tide in the coastal marshes from roughly 4 a.m. to 6 a.m. Second, we experienced winds from the south and an atmospheric inversion, which created something like a low-lying bubble of air.

The result of the two factors? The low tide exposed the marsh sediments and hastened the release of sulfur gases into the atmosphere. The inversion trapped the odor close to the groundand the southerly winds then carried it to Lower Manhattan, where it remained until atmospheric conditions changed.

Damn, this is CSI NY (Atmospheric Chemistry and Modeling Division), good stuff!

Our explanation highlights the consequences of excessive nutrient loading and the resulting low oxygen levels in local coastal waters. (By nutrient loading, we mean exposing water to sewage, fertilizer, chemicals or other pollutants.) Of course, these consequences go beyond odor — they kill marsh vegetation, degrade the wider marine habitat and make it unsafe to swim or fish.

Indeed, so the cause, while natural is not really natural, it is from untreated sewage. New Yorkers, stop blaming New Jersey! Look at yourself!

Obama seeks U.S. carbon emissions cap

Byoliveridley

President Barack Obama on Tuesday called on Congress to send him legislation that places a market-based cap on U.S. carbon polluting emissions and pushes the production of more renewable energy.

In his first speech to a joint session of Congress, Obama said that “to truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy.

Good, Canada will have to harmonize. Stephen Harper was last seen pretending that his “intensity based”” approach was just a “different” way of measuring emissions. You can say that speed and distance are just two ways of measuring travel!

It is still early and we will see what the US congress can come up with, and what egregious exemptions and offsets it will provide for. Lobbying is already fast and furious. But the news emanating from Obama is promising on the climate change front.

The England Environment Minister Blogs

http://www.davidmiliband.defra.gov.uk/blogs/ministerial_blog/default.aspx

He seems to write it himself, has comments and all, some of which aren’t very friendly. One of his posts talks about a Carbon ration card, meaning everyone starts off with a set of carbon credits, which you can either use, or sell back to the trading bank so that people who use more carbon can buy more.

The principle is simple: there would be a decision about the nation’s
annual level of carbon emissions, permits/quotas for that level would be issued on a per capital basis (probably for personal food, household energy and travel emissions), and those who spent under the wuota would be able to sell to those who spend above.

Well put, and in classic blog style, no spellcheck!

Meanwhile, in the US, we have the chair of the powerful Senate Committee on Environmental and Public Works and well known Global Warming denier.

But coolness and hipness aside, it is refreshing for a minister (secretary, whatever you call them) to communicate in this fashion and be accepting of comments and criticism. We need a few more of these on the other side of the Atlantic (no,  not Antarctica, look West).

  1. It’s a move in the right direction, but one also needs to take into account how the electricity used to charge the car is generated. If it’s coming from a coal-burning plant then there are still plenty of GHG emissions in the equation.

  3. That was a big concern for me too. That is why I use wind energy to fill up my plug-in Prius. So I reduce my carbon emissions with clean energy and not coal. It is just a small step in the right direction, but one I hope most will be willing to take.
