PAXScientific's Streamlining Principle

Submitted by esaruoho on September 6, 2008 - 11:08

The Streamlining Principle As a naturalist with the Australian Department of Fisheries and Wildlife, Jay Harman developed a fundamental understanding of flow geometries by observing the patterns of ocean and air currents. He repeatedly encountered the impressive effectiveness and energy efficiency of natural fluid flow, and discovered that these systems share common geometries.

How would nature do it?

The Sycamore Seed and the Maple Seed

We've been doing the ceiling fan thing all wrong for all these years. Turns out the best design for a fan blade is to twist it into the shape of a seed pod from a Sycamore tree. Spin it around at just 70 to 130 revs per minute, and you get the same airflow as a regular fan cranking its heart out at twice that speed. We're also digging its weirdo looks, too.

Building them like Nature shows how to

Learning from Nature How to Create Flow Without Friction

Part 1B Engineering: Biological and Medical Engineering, Fish Swimming, Lecture 1 -2 - Trout_propulsion.pdf

..."Evidence suggests that many fish exploit the natural instability of the flow energetics to assist them in propulsion and maneuvering. By tuning their own kinematics, the fish is able to swim efficiently, to generate large thrust and turning forces, and to move silently through the flow with minimal wasted energy...."

MERLib supports

MERLib supports the Wilhelm Reich Museum / Wilhelm Reich Infant Trust through using GoodSearch / GoodShop to gather money for this non-profit-organization. In addition to running the physical museum, they are in charge of producing two full-length documentaries on Wilhelm Reich, are working on a book which will have the 1947-1957 letters, diaries and scientific studies of Wilhelm Reich, so we will better be able to comprehend the latter decade of Wilhelm Reich's life. A Biopic and a full-length documentary would be beneficial at clearing the name of Wilhelm Reich after the travesties of "W.R. - Mysteries of The Organism", and the scant footage available on Wilhelm Reich or his devices. If you know there is something to Wilhelm Reich's orgone discoveries, his orgone accumulator, orgone shooter, orgone blanket, and orgone cloud-busting devices, if you find that there should be more information on the atmospheric orgone motor, and the human orgone-energy running motor, conditioned vacuum-tubes which respond to orgone.. if you believe orgone plays a part in the nuclear energy and preservation of nature question, then please start using GoodSearch from now on and point all of your search-"income" to the "Wilhelm Reich Infant Trust Foundation". As of September 2008, 17$ has accumulated by a few persons using it. That is 0.01$ per search and use. If you use eBay via GoodSearch (GoodShop), a larger percentage will be donated to the trust. The Wilhelm Reich Museum are attempting to collect over 200,000$ for the singular production of two of these films, they also require time and funds for the research, translation and compilation purposes of the 1947-1957 followup to "American Odyssey", a previous Wilhelm Reich study compilation which featured his encounters at explaining Orgone energy to Albert Einstein. And also, they now require funding for a new roof.
