Wave power is the wave of the future
Wave power can provide an endless source of clean cheap power.

Hey, Dude, let’s catch some waves! Surely, every surfer in the world knows the power behind those waves, as does anyone whose ever fought the undertow to swim back ashore.  An Australian company Carnegie Corporation believes that waves are indeed the wave of the future, and could supply up to 35% of Australia’s energy needs.  Acknowledging that wave power faces stiff competition from other renewable forms of energy particularly wind and solar, managing Director Michael Ottaviano is none-the-less optimistic that wave power will become popular over time as the cost of harnessing the awesome power of the sea decreases.

“We know that our first plant will generate power at about the ame price as wind,” Orraviano explained, “Solar was twice as expensive 10 years ago … if we start out where wind is, we know that in five to 10 years we’ll be fossil fuel competitive.”Dr Ottaviano cites an RPS Met Ocean report that shows that more than 17,000 megawatts of wave energy can be extracted at any given time off Australia’s coasts.  “This means that around 35% of Australia’s current power usage could be met by harnessing wave energy,” Dr Ottaviano concluded.

The system works by capturing the motion of buoys that are tethered to the sea floor which then drive compressed water to the shore where it is converted into electricity by forcing it through a Pelton turbine generator.  Compressed water has some distinct advantages over offshore wind turbine generators in that compressed water can be stored in tanks for use during peak loads, and aside from some slight friction losses there is very little loss of power traveling the distance to the shore.  When sending electricity from a wind turbine, or any time you transmit electrical current, transmission line losses are a real challenge.

The thing I like best is that the schematic includes powering a water desalination plant and then transmitting the remaining power off to wherever it’s needed.  What this world really needs now, and more so in the future is an answer to the water shortage that is coming that will make peak oil seem like a walk in the park.  This system seems to address both issues, so I will be keeping a close eye on developments!

Olympic volunteers
Olympic volunteers have shown up in booths all over the city

To all the naysayers about the air quality in Beijing for the Olympics, all I can say is that if the games were held right now, the weather would be incredible. Yesterday was one of the finest days I’ve ever enjoyed in Beijing with wonderfully clear air and great visibility. I could see both the western and northern mountain ranges with amazing clarity! I spent the day running errands all over town and therefore found myself riding my motorbike for a goodly portion of the day. The temperature was perfect!! The air quality index was “Excellent” at 27, the best I have ever seen. Today was also a glorious day, but HOT!

Beijing air quality is excellent!

When it comes to air quality in Beijing for the Olympics, there have been quite a few naysayers indeed. It seems many in the western press were publishing pictures of last week’s hazy days as evidence of poor air quality, failing to mention that there was quite a bit of sporadic precipitation that had evaporated into the air to make the haze. The Beijing government was quick to point out that haze is a natural phenomenon common throughout China. I am with the Beijing government on this one. There is a big difference between haze and smog, and anyone buzzing around town on two wheels can certainly tell the difference! China has always been hazy, as anyone who has ever seen a Chinese painting should be able to discern. Where does all that mystical mist come from in those beautiful paintings? Smog? In the Tang Dynasty? I don’t think so. I may be the first to voice my cynicism when certain negativities are downplayed, but I must say that the air quality this past week has really, really improved, no doubt largely in part the vastly reduced number of vehicles on the streets. I hope that after the games are over they keep the regulations in place limiting access to Beijing roads by even or odd numbered plates only able to drive on even or odd days. Of course, the over 300,000 vehicles from state-owned enterprises that have been restricted throughout the games will most likely hit the streets again when they end. No matter. I am truly enjoying the fresh air while it lasts.

Other signs that Beijing is fully prepared for the games:

1. Security measures have become routine. I went to an opera (Tea: A Mirror of Soul) at the National Center for Performing Arts and did not feel entirely put out by the security search to enter the massive hall. People have grown accustomed to these measures, and some efficiencies have been developed by those carrying out the searches.
2. Hordes of volunteers have emerged. Having served as an Olympic and Paralympic volunteer myself during the Salt Lake games, I know a thing or two about the procedures and organizational structure, and I can attest to the fact that Beijing has a definite advantage – neighborhood committees!

Everyone in China is organized into groups, traditionally according to work place or school. Housing has also traditionally been assigned by the company, though that is rapidly changing. As everyone is assigned to unit, each unit has a committee and each neighborhood has an organized “neighborhood watch” committee, who are basically retired people who sit around and spy on everyone going in and out of the community. They are actually empowered to do so by the local communist party! This level of organization comes in handy from time to time, especially when the government wants to implement an information campaign. Now, the red arm bands have been replaced with red and white volunteer outfits and you can literally find them on every street corner throughout the city. Wow!

3. An even more amazing display of flowers on the street than usual. I’m always amazed how the flower displays get more and more impressive every year around National Day, but this year they have pulled the stops to put up impressive flower stands along side of all the major roads and in many neighborhoods.
4. Cosmetic surgery to all of the older building fronts was completed in a timely fashion. If you are one of the lucky few able to visit Beijing for the games, you will notice that nearly every building has the same matte silver tile surface and brand new signage, thanks to a beautification plan that was implemented on a massive scale that can only happen in China.

Solar powered lights in a park in Beijing - but something is wrong with this picture
Solar powered lights in Beijing parks are great, but something is wrong with this picture!

While the finger-pointers in the West may look scornfully upon China as the biggest threat to global warming, despite that fact that many of China’s emissions are a direct result of offshoring by said finger-pointing countries in an effort sate the mindless consumerism of the local residents, who don’t want such dirty stinky polluting factories in their own back yards, especially as it wouldn’t be “environmentally friendly”, few may be aware that from a policy standpoint, at least, China is in many ways ahead of the pack. Now if we can only work on execution…

There is, sadly, a major disconnect between the lofty heights of academia and government, and the real world of practical implementation. I’m not even talking about the selfish money-centered attitude that manifests out of a universal human tendency to choose what it is good for an individual personally, even at the cost of the community as a whole. I’m talking about something far more fundamental. Knowledge takes time to trickle into human consciousness, despite the best intentions.

If you haven’t taken a good look at the picture above, please do so now, and see if you can find something wrong with the picture. At first glance, the picture can be seen as a true measure of progress… solar powered street lights using CFL lamps in a public park in Beijing. However, something went dreadfully wrong with the installation - a major disconnect between the supplier of the new technology and the park planners. Have you guessed correctly! Well done! Go to the head of the class.

For those of you who aren’t as familiar with the nuts and bolts of renewable energy technologies, take a look at the orientation of the solar PV panels atop each street light. They are all facing different directions! Some are facing in opposite directions!! Which means that they are working at a fraction of their capacity, as solar panels should be aligned for maximum exposure to solar radiation throughout the day, in a southward direction in the northern hemisphere. Ideally, the angle of the panel should be adjusted for the time of year, as the sun is much lower in the sky during the winter than in the summer.

Now, it could very well be that the designers of the panels have over-designed them to be able to operate in spite of such gross inefficiencies, but if this is so, then this too is simply inefficient. As solar panels are still rather costly to produce and come with an environmental price tag when considering their manufacturing process, as well as disposal and recycling, greater care and consideration should accompany their use.

So, what are your views? Am I overly critical? Not critical enough? You tell me.
