One of the Holy Grails of green power is hydroelectricity, and we've certainly seen our fair share of research in that department. The newest guy on the scene is called Oyster, a collaborative effort between Queen's University in Belfast and Aquamarine Power Limited that sees something called an Oscillating Wave Surge Converter placed offshore (in depths around 10-12 meters). When moved by waves, the device's double acting pistons push seawater ashore via high pressure flow lines, where it is converted to power using tried and true hydroelectric generators. Since the hydroelectric plant is located onshore, it is accessible for maintenance 24-7. According to the company, peak power should be around 300-600 kw, depending on the unit's configuration and location. The first prototype is to be deployed off the coast of Orkney this summer, where we'll see if it can transform high tides and abnormal weather patterns into juice for your Xbox. One more pic for you after the break.
Surely this can be applied here in Chicago, right?
Enwave and the City of Toronto have created an innovative cooling system that brings an alternative to conventional air conditioning to cool Toronto's downtown core — one that is clean, price competitive and energy efficient. A permanent layer of icy-cold (4°C) water 83 meters below the surface of Lake Ontario provides naturally cold water. This water is the renewable source of energy that Enwave's leading-edge technology uses to cool office towers, sports & entertainment complexes and proposed waterfront developments.
The system has been in operation since 2004.
A similar form of air condition is being used in Halifax, Nova Scotia. At Purdy's Wharf, we read here, it ‘provides all the cooling for the building for 10 1/2 of the year. During the remaining six weeks, the buildings use conventional chillers, but the seawater is used to cool the condensers. The system was paid off in two years, and saves the complex more than $100,000 annually in electricity and maintenance costs.’
In the U.S., Cornell University is implementing its own deep lake water cooling system.
While children have fun spinning on the PlayPump merry-go-round (1), clean water is pumped (2) from underground (3) into a 2,500-liter tank (4), standing seven meters above the ground.
A simple tap (5) makes it easy for women and children to draw water. Excess water is diverted from the storage tank back down into the borehole (6).
The water storage tank (7) provides a rare opportunity to advertise in outlaying communities. All four sides of the tank are leased as billboards, with two sides for consumer advertising and the other two sides for health and educational messages. The revenue generated by this unique model pays for pump maintenance.
Not surprisingly trying to assess the design and application of the PlayPump system took us on an emotional roller coaster ride. One minute we were giddy with enthusiasm (‘Fucking brilliant!’), but the next minute, completely raving with skepticism (how long do the children have to twirl and twirl around to fill the tank; and is the water any safer?), only to return back to unbridled enthusiasm (well, it's not as if the goal is to provide communities with daily showers, car washes, and indoor toilet flushes; and surely groundwater is reliably safer than the surface water sources to which the PlayPump offers an alternative).
Back and forth.
Convinced how cool the whole thing is, we soon found yet more reasons to doubt the viability of this earnest endeavor: aren't there better options, such as these? Well, of course. The PlayPump isn't meant to be the singular solution for every possible situation. Aggregation is a good strategy.
Counterproductive as we sometimes are with our privileged misanthrope and ironic asides, we asked ourselves: don't you find the ads a bit troubling, even comical? (Advertising in economically depressed areas? Is this like Colors by Benetton or something?) To which we replied: Yes, we are indeed privileged.
Back and so forth.
But before we reverted back to our usual default position of enthusiastic interest, we asked one last question: wouldn't it be better to just give a sizable chunk of what we in the United States spend on public water services -- to recreate, for instance, some sort of Edenic fantasies in the desert Southwest with water diverted from severely depleted sources -- to sub-Saharan African nations where the money will be used to improve their hydrological infrastructure, and we are the ones who get to install the PlayPumps in our school grounds and playgrounds where a growing population of obese, diabetic, allergic children, the ones inured to the hardship of suburban domesticity, are forced to trim a little bit of the fat, reduce susceptibility to diabetes, and prevent future addictions to Allegra® and Claritin® while teaching them about the incredibly, wonderfully awesome subject of hydrology, imparting a life long commitment to water conservation?
A 6,000-kilometer (3,700-mile) transport corridor from Siberia into the U.S. will feed into the tunnel, which at 64 miles (103 km) will be more than twice as long as the underwater section of the Channel Tunnel between the U.K. and France, according to the plan. The tunnel would run in three sections to link the two islands in the Bering Strait between Russia and the U.S.
The planned undersea tunnel would contain a high-speed railway, highway and pipelines, as well as power and fiber-optic cables, according to TKM-World Link.
The project, which Russia is coordinating with the U.S. and Canada, would take 10 to 15 years to complete.
