Biomimicry and Ocean Generated Energy: Are Humans Smarter Than Sea Sponges?

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.

A further comment on "That's Oil, folks . . ."

Prof G has just made reference to the new article in Nature, concerning the possibility of Peak Oil, and hiding under the title “That’s oil, folks . . .” It begins with a comment on the Boston Meeting on Peak Oil and Gas last October, but largely is a review, by their Chief of Correspondents of some of the issues, with the major proponents of the opposing sides being Matt Simmons and Peter Jackson Of Cambridge Energy Research Associates (CERA).

While, I suspect that there is little real benefit is re-rehearsing all the arguments that we could put forward, since they have been brought up in a number of responses to the publications of CERA over the past few months, particularly those by Dave and Euan, though they merely exemplify a number, yet I feel a response is called for since, inter alia, the President of Aramco just said:

Over the last several years, no less than thirty books have been devoted to the “peak oil” theory, the imminent exhaustion of oil, and the world’s inability to grow future petroleum supplies. The peak oil proponents routinely used the rise in oil prices over the last several years as evidence for their arguments about scarcity, but with the recent pullback in prices and the moderating call on oil from Saudi Aramco and other major producers, many now acknowledge there is actually an oversupply of petroleum in the market. In fact, what seems to be in short supply these days are vocal peak oil theorists!

Well, the rising production of the growingly-expensive alternate fuel, ethanol, would suggest, at least to some, that this is more than a theory, and the growing inability of some of the poorer nations to provide adequate power to their people would underline that suggestion. The demand destruction that lowers demand and thereby stretches supply is already occurring.

Nature takes on peak oil (pun somewhat intended)

There's a new article in Nature on peak oil here.
(sorry, it's behind a paywall, [ED by PG] but I've discovered you can find excerpts of it here at EB. Thanks BA.)
Consider this a discussion thread for quotes from that piece and an open thread as well...
