Biomimicry and the “Evolution” of Tidal Energy

The Oil Drum just posted a great article about the “evolution” of tidal generators and the rise of biomimicry in general. Essentially by mimicking the design of plants and sea-swelling creatures that have adapted to an underwater environment for millions of years, we are able to build systems and devices that are more likely to achieve peak efficiency…or at least go a long way towards it. From the article:
In my post on ocean energy a few months ago I briefly mentioned a scheme by a small Australian company called BioPower to trial some tidal power and wave power technologies in Bass Strait that used “biomimicry” based design principles. The project is due to go live next year, with 2 prototype units being deployed – the wave power system will be off King Island and the tidal power one off Flinders Island. Each unit can produce up to 250 kilowatts. The $10.3 million system is half funded by the Australian Government and the electricity generated will be used by Hydro Tasmania. BioPower CEO Tim Finnigan says the locations were chosen because Tasmania “offers a world-class wave climate on the west coast and a fantastic tidal environment on the eastern side”. The field of biomimicry (also called “biomimetics” and “bionics”) is a new one that has gathered an increasing amount of attention in recent years, with advocates promoting these types of designs as being efficient ways to harness natural resources and to use them in a sustainable way. In this post I’ll look at the history of the science (apparently you can get a degree in it now) and at a range of examples where it is being applied.

Why Modern Wheat Is Making Us Sick

Why is modern wheat making us sick?  That’s the question posed by author Eli Rogosa in her new book Restoring Heritage Grains.Wheat is the most widely grown crop on our planet, yet industrial breeders have transformed this ancient staff of life into a commodity of yield and profit—witness the increase in gluten intolerance and ‘wheat […] Read More

A Dictionary to Survive the Future

When British economist David Fleming died unexpectedly in 2010, he left behind his great unpublished work, a masterpiece more than thirty years in the making—an intellectually evocative and inspiring dictionary, Lean Logic: A Dictionary for the Future and How to Survive It. In it, Fleming examined the consequences of an economy that destroys the very foundations—ecological, […] Read More

Overshoot, Collapse, and Creating a Better Future

In 2016, Earth Overshoot Day happened on August 8—the day when we’ve exhausted the planet’s resources for the year, and are essentially borrowing from future years to maintain our existence today.Perhaps you celebrated this day with a counter-solution: a vegetarian meal, telecommuted, or turned off the air conditioning. There’s a lot more you could be […] Read More

Plants & Pests: Will Bonsall’s Advice on “Wee Beasties” in the Garden

“From a plant’s point of view there is little difference between a cutworm, a woodchuck, a blight spore, and, for that matter, us.”“These are all things that in one way or another prey upon it. It is an inevitable constraint of all living things: We escape one peril only to ultimately succumb to another,” so […] Read More

To Create Climate-Secure Foodscapes, Think Like a Plant

The techniques and prophetic vision for achieving food security in the face of climate change contained in Gary Paul Nabhan’s Growing Food in a Hotter, Drier Land may well need to be implemented across most of North America over the next half-century, and are already applicable in most of the semiarid West, Great Plains, and […] Read More
