Korea vs. Japan: There’s No Sex In Whaling

“Are you Russian?” asked a middle-aged Korean man hopefully to an American English teacher. Translation: are you a prostitute?

“Are you Japanese?” she retorted. And that was that.

It’s the best rebuff I’ve heard to the bevy of Korean men who equate blonde hair with instant gratification. But why did it repel him with such shear efficiency? Or, put another way, what’s so bad about being called Japanese?

Australia Combats Japanese Whaling

It’s summer in the Antarctic Ocean and many whale species have migrated to the Southern Ocean Whale Sanctuary, an important feeding ground. One would think that in an internationally recognized sanctuary at the ends of the Earth, these whales would be safe from the boating, fish netting, noise pollution, and other man-made hazards.

However, Japanese whaling fleets have already left harbor to hunt the whales for meat in this sanctuary as they have done increasingly since 1997 in defiance of international bans on whaling.

Each year, Japanese whalers slaughter more and more whales. This year, the Japanese whaling industry has vowed to kill the greatest number of whales yet, about 1000 in all. These numbers will be made up of near-threatened Minke whales and 50 endangered Fin whales.

But this year, they will not be alone on the rough seas against the Japanese whalers. Australia’s new government is joining Greenpeace in saying “enough is enough.” As Josh Hill writes, this pressure is already beginning to bear fruits. Japan has agreed to suspend–at least for the moment—its plans to kill an additional 50 threatened humpback whales.

Australia is sending ships usually reserved for tracking down marine poachers to monitor the whaling vessels. That’s not all. There will also be eyes in the sky as an Australian surveillance plane record the whaler’s every action from above. This is all just part of a larger effort that Foreign Minister, Stephen Smith, hopes will help put an end to Japan’s horrible whale hunt once and for all.

Yet Another Wind Power Design

A seemingly simple alteration a wind turbine blade’s traditional shape could result in huge improvements in efficiency.

WhalePower Corporation out of Toronto, Canada has designed a turbine blade with rounded, teeth-like bumps along the leading edge. The company’s name is a nod to the humpback whale, whose flipper was the inspiration for the design.

The agility of the humpback whale is astonishing, given that they can be over 50 feet long, weigh nearly 80,000 pounds, yet move quickly and tightly in the water. One of the animal's advantages, according to scientists, is the unique row of bumps or “tubercles” along the leading edge of their flippers that dramatically increase the whale’s aerodynamic efficiency. Specifically, researchers found a 32 percent lower drag and 8 percent improvement in lift from a flipper with a serrated edge compared to a smooth one.

Businessman Stephen Dewar heard about the humpback research and contacted one of the scientists involved, Professor Frank Fish of West Chester University in Pennsylvania. After a few meetings, they enlisted the help of some local engineers and formed WhalePower, taking a cue from Mother Nature and modeling their blade design after the whale’s flipper.

WhalePower claims that their turbine design can capture more wind energy at much lower speeds than traditional designs. The channels created by the teeth at the blade's edge cause separate wind streams to accelerate across the surface of the blade in rotating flows. These “energy-packed” vortexes increase the lift force on the blade. For example, Dewar told the Toronto Star that this design produces the same power at 11 miles per hour that one would expect at 18 miles per hour. Furthermore, he claimed these channels prevent airflow from moving along the span of the blade and past the tip, which can create noise, instability and a loss of energy. By keeping the air flow nicely channeled, more wind is captured and noise is reduced.

Dewar sees this “biomimicry” design – the fusion of biology and engineering – reaching beyond wind power.

“’This changes the game,’ says Dewar, adding that any system using a fan or turbine could also benefit from the new design. This includes everything from better turbines for hydroelectric generation to residential ceiling fans that use less electricity. ‘If we've got what we think we've got, then the range of applications is staggering.’”

The Ontario Centres of Excellence and the Ontario Power Authority have contributed over $60,000 USD for early research and to encourage collaboration with a wind engineering group at the University of Western Ontario. The next and arguably most crucial step to commercial production is independent, third party verification of the blade’s performance.
