Whales Protected from Navy for Now

Improving engine efficiency and reducing pollutant emissions are extremely important. Here, we report our fuel injection technology based on the new physics principle that proper application of electrorheology can reduce the viscosity of petroleum fuels. A small device is thus introduced just before the fuel injection for the engine, producing a strong electric field to reduce the fuel viscosity, resulting in much smaller fuel droplets in atomization. Because combustion starts at the droplet surface, smaller droplets lead to cleaner and more efficient combustion. Both laboratory tests and road tests confirm our theory and indicate that such a device improves fuel mileage significantly. The technology is expected to have broad applications, applicable to current internal combustion engines and future engines as well.

Electrorheology Leads to Efficient Combustion.

According to the press release, this is a very simple device. It has one small advantage over the usual snake oil, it is academic research and has been peer reviewed.

Good stuff, hope this is an easy after market addition to any vehicle with fuel injection. However, the press release also notes that the prototype is being developed for diesel engines only, and that the research was based mainly on diesel, wonder why…

Hidden in the beginning of an article on a county heavily dependent on coal contemplating a switch to natural gas heating…

“Heritage should account for something,” said James J. Rhoades, a Republican state senator from Schuylkill County.

King Coal Country Debates a Sacrilege, Gas Heat – NYTimes.com

Of course, this argument can be made to defend any practice including child marriage, the caste system, widow burning, slavery, genocide (the list goes on…). Coal is in august company.

Some of the issues with anthracite:

But what makes this brittle and lustrous rock, often known as black diamond, so hard and pure is that it is often deeper and under greater pressure than other forms of coal, which also explains why it is expensive and dangerous to extract.

The anthracite mines in this area have seen more than 30,000 deaths since 1870.

The argument about local jobs being lost and local economies being damaged is a valid one and needs to be addressed. In theory, destructive practices cannot be continued in order to prop up local economies. But decisions are made locally and it takes a lot of political courage to shutdown a destructive economy and possibly doom a town to fast death. I guess the solution is to provide alternative modes of economy and employment growth during the transition, easier said than done. Problem with being a one horse town, you better hope your horse stays forever young!

No, not Tyra Banks and Riyo Mori, climate models that is.

ES&T Online News: Models underestimate global warming impacts

Modelers don’t purposely err on the conservative side, says Marika Holland of the National Center for Atmospheric Research, but some processes “are just not well understood, and because of that have not been incorporated into climate models.” Holland has published model results on the fate of sea ice and coauthored the recent paper showing that ice is melting faster than models predicted. There are many reasons for the underestimates, she says. For example, models don’t fully capture heat transport between ocean and atmosphere, or faster warming as reflective ice gives way to darker, heat-absorbing waters.
But Rahmstorf says that modelers might unwittingly make models more conservative by applying “one-sided filters”, weeding out models that clearly overestimate the changes seen so far, but hanging onto ones “where everything is too well behaved and stable.”

Scientists are human too. The political and social climate in the US have been harsh to people who overestimate the effects of climate change. So, modeling scenarios that deviate significantly from accepted limits or runaway uncontrollably are discarded. Models are sets of assumptions based on underlying theory. If the theory of a particular sub-process is not clearly understood, then the assumptions become subjective. In a social climate that is waiting to pounce on an overestimate as example of negating the entire global warming phenomenon, assumptions made are conservative. This is not necessarily a bad thing, but it comes at a price! As more observations come in, it does become clear that sometimes, things are happening faster and at greater magnitudes than our model predicted.

This is the NY Times headline, not mine!

Judges Overturn Bush Bid to Ease Pollution Rules – New York Times

But on Friday, the court said the agency went too far in 2003 when it issued a separate new rule that opponents said would exempt most equipment changes from environmental reviews — even changes that would result in higher emissions.

With a wry footnote to Lewis Carroll’s “Through the Looking Glass,” the court said that “only in a Humpty-Dumpty world” could the law be read otherwise.

“We decline such a world view,” said their unanimous decision, written by Judge Judith W. Rogers, an appointee of President Bill Clinton. Judges David Tatel, another Clinton appointee, and Janice Rogers Brown, a recent Bush appointee, joined her.

The winners this time —more than a dozen states, including New York and California and a large group of environmental organizations — hailed the decision as one of their most important gains in years of litigation, regulation and legal challenges under the Clean Air Act.

The provision of the law at issue, the “new source review” section, governs the permits required at more than 1,300 coal-fueled power plants around the country and 17,000 factories, refineries and chemical plants that spew millions of tons of pollution into the air each year.

The proposed rule would have allowed powerplants to avoid putting new controls in as long as the cost of equipment did not exceed 20% of the replacement cost of the plant. Fuzzy math, anyone! This would have let to major incentives to not build new plants using cleaner technology, but keep the “grandfathers” running. A lot of the old plants were exempted from some of the strict controls by being grandfathered into the act. Well, call me cruel, but grandfathers eventually die! I thought of this proposed rule as the “Bionic Grandpa” provision! Glad that the courts did not like it.
