Sea Power

The Sea as well as Space, has enormous potential to provide civilization with large scale energy, so I'm glad to see that the Australian government is supporting Australian company attempting to commercialize sea power.

The CETO system uses the wave power of the undersea:

Commercial wave-powered water desalination and electricity generation is one step closer to reality, according to Australian developers.

Trials of a technology called CETO have yielded promising results, says Dr Michael Ottaviano of Carnegie Corporation, which is developing the system in the southern hemisphere.

The tests, carried out in Fremantle, Western Australia, verify predictions of how much electricity and water the technology could produce under various wave conditions.

"We've found a perfect correlation between the results our models predicted and what we've actually measured in the ocean, which is a major technical milestone," Dr Ottaviano said.

The CETO technology, first conceived by Perth-based inventor Alan Burns in 1975, consists of submerged buoys connected to seawater pumps fixed to the seabed.

As each buoy moves back and forward with the swell, it generates energy to pump seawater onto land at high enough pressures to drive a reverse osmosis desalination plant as well as hydroelectricity turbines.

The company has just spent two years developing a computer model of the buoy and pump system, which calculates how much power and water it can deliver back on shore according to different wave conditions.

The computational fluid dynamics model uses the same software used to design racing cars and boats for the America's Cup.

"We can also now go to any number of sites, measure the wave conditions there, plug those conditions into our models and then tailor a design of the unit to each specific site that we go to," Dr Ottaviano said.

He says tailoring the units to particular sites would involve changing the buoyancy of the buoy and the design of the pump.....

Pulling the Plug Nearing Release

With the environment seriously degrading by the minute and oil closing $90 USD a barrel, the alternative energy book PULLING THE PLUG is on schedule for a December release. Here is what the promotional material says:

Pulling the Plug - Real Personal Energy Independence - A Homeowner's can-do guide to unplugging from the grid one step at a time.

"Dennis Chamberland makes it easy for everyone to unplug from the energy grid. Now the average homeowner or renter can unplug from electrical power, gas and heating oil grids permanently – one small step at a time! Well placed rumors have stated that unplugging from the grid is far too expensive for the average family and further, that the equipment expenses are so high they will never be returned in actual savings. Chamberland shorts out those rumors in easy to understand language and by demonstrating that the entire house does not and should not be unplugged all at once. Instead, he offers a revolutionary new method of powering down from the grid and powering back up on your own energy system using the free energy that literally falls and blows about your home each day. Now you can be your own power company and harvest the free energy that is wasted on your own property each and every second. And you can do it one circuit, one simple affordable step at a time!”

The cover price for the book is being hotly debated but it looks like it will be a reasonable $14.95. Following that release, ABYSS OF SPACE will follow shortly – I hope!

Our Robotic Future

So you think gay marriage is a bit strange:

HUMANS will be marrying and having sex with robots by 2050, an artificial intelligence researcher has claimed.

Netherlands university student David Levy, who recently completed his PhD on the subject of human-robot relationships, told LiveScience that robots would become so human-like in appearance, function and personality that many people would fall in love with them, have sex with them and even marry them.

"At first, sex with robots might be considered geeky, but once you have a story like 'I had sex with a robot and it was great!' appear in a magazine like Cosmo, I'd expect many people to jump on the bandwagon," he said.

In his thesis "Intimate Relationships with Artificial Partners", Mr Levy argued that psychologists have identified roughly a dozen basic reasons why people fall in love, and almost all of them could apply to human-robot relationships.

"For instance, one thing that prompts people to fall in love are similarities in personality and knowledge, and all of this is programmable," Mr Levy said.

"Another reason people are more likely to fall in love is if they know the other person likes them, and that's programmable too."

Mr Levy said Massachusetts would be the first jurisdiction to legalise human-robot marriage. .....

North West Passage Mystery

Picture BBC news

Is global warming opening the North West Passage? This article seems to indicate it is:.

Warming 'opens Northwest Passage'

The most direct shipping route from Europe to Asia is fully clear of ice for the first time since records began, the European Space Agency (Esa) says.

Historically, the Northwest Passage linking the Atlantic and Pacific Oceans has been ice-bound through the year.

But the agency says ice cover has been steadily shrinking, and this summer's reduction has made the route navigable.

The findings, based on satellite images, raised concerns about the speed of global warming........

Please read the full article. Lets examine the article with our brains turned on. Firstly when did these records actually begin? Well, the article gives a date 1978. Surely you would want a longer baseline to be sure the melting is unusual.

Theres more, readers of this blog would be aware of the Sebastien Roubinet Alaska Greenland Expedition. This was an successful attempt to transverse the North West Passage in one season using a specially designed sail boat that could travel over ice as well as water. The passage usually does clear during August and September but there was no lack of ice this summer:

There were icebergs and lots of thin ice, (2-3 cm) - not enough to sail on; but just enough to slow the speed when pushing the ice sheets. The stays froze, and so did the crew - shivering through their night watches on a deck turning white.

Now, I'm not sure whats going on here, bad journalism, bad science, a bit of both or maybe I'm completely wrong with my analyses. I'm interested in any comments people have. But if this story was really based on an ESA report wheres the critical thinking and investigative reporting Mr BBC reporter?
