Designing the Next Golden Age

By Jay Harman

The following text is from a speech given at Bioneers 2004.

Welcome to the new Golden Age! Yes, here, today, right now, in what may feel for some of us like the darkest of times, we are creating a new Golden Age. I think we’re ready for this. We know, deep inside, that a better age for our world is absolutely crucial, and we know it’s possible. That’s why we continue to get up in the morning—to strive for a better world. For me, I know this new Golden Age is possible because of what I’ve learned from nature.

Nature.

Expansions are retarded explosive effects in the realm of basic substances, in which decentrating (expanding) reactive effects of a subordinate order are freed.

Impansions are slow processes of densation, which for example, can be exploited in so-called chillers or refrigerating machines and are to be viewed as normal de-stressing processes.

Explosion is chemical reaction that takes place extremely rapidly, in which a large increase in pressure occurs due to large quantities of hot gases. Explosions are always innately destructive. They therefore function in a life-harming way.

When Jay Harman was a skinny 10-year-old swimming off the coral reefs of Australia's western coast, he had an insight that 37 years later would lead him to invent an industrial design that could change personal computing, aeronautics and how drinking water is purified.

As a nature-loving boy, the young Australian just wanted to swim faster, so he watched how fish moved through water and how seaweed undulated against the reef when a wave crashed.

The shape he noticed that day was a simple curve that fluidly formed into a spiral. From then on, Harman would see spirals as a common design in nature--in pinecones, whirlpools, a puff of smoke.

Now he believes spirals are a key to making a wide array of machines more energy-efficient. Through his 9-year-old company, Pax Scientific, he's trying to bring that natural form into the technological world. So far, he's invented industrial designs for fans, pumps and propellors that mimic the geometries of spiraling whirlpools. Experts believe these designs can reduce friction, wasted energy, noise and unwanted heat.
