Oahu Is Rising


Literally!

This is not about economic growth, intellectual enlightenment, or attaining some other form of excellence. 

This is a matter of fact statement about the geography of Oahu: It is rising. Every century the Koolaus will grow taller.

Contrary to global warming theories that for decades have suggested that Oahu’s shores will be inundated and beaches will be lost, new scientific analysis shows that even with possible sea lever rise, and even with the constant erosion of the island by wind and rain, Oahu will grow taller thanks to strong volcanic forces that lift it up from the bottom of the ocean.

The effects of climate, soil thickness, and water contact times on Oahu, Hawaii is the title of the article by Stephen T. Nelson, David G. Tingey, and Brian Selck from the Department of Geological Sciences, at Brigham Young University, in Provo, Utah.

Here is their remarkable conclusion: “Recent work indicates that Oahu is tectonically emerging at 0.060 m/ka. As long as this uplift continues, the net size of the island will slowly increase and the Koolau Range should persist as an orographic trap to precipitation, maintaining relative aridity in the Waianae Range.”

That’s 6 cm every 1,000 years. Not sure if that's enough to protect from any sea level rise due to polar ice melting.

New 3-Cylinder Ford Engine Delivers 47 mpg!

Alan Mulally is the venerable engineer and project manager of the Boeing 777 and for several years now CEO of Ford Motor Company. Why is he kissing this new engine?



Because this super-efficient, well-balanced and light weight engine can deliver 47 mpg in a Ford Focus compact car without the complexity and price penalty of hybrid technology. Many manufacturers are now turning to 3-cylinder engines for their smaller cars but also prepare editions that match the output of common V6 engines for larger vehicles.

These smaller engines would have huge benefits for the world market, and China in particular, where Volkswagen announced plans to build its 7th plant, just a few days after Ford had said it would build its 5th.

This is good news for mobility and the planet. Smart policies* and smart engineers get the job done: Mini engines with normal performance and mini consumption and air pollution. And fewer resources used to make those engines enhances long term sustainability.

Note (*): America's new emission standards require car manufacturers to achieve a fleet average of 34.1 mpg by 2016 and 54.6 mpg by 2025.
