1. What if Africa was Europe’s power plant?

    What if Africa was Europe’s power plant?: “Africa

    Last week, The Guardian reported that Europe is looking to Africa to serve its energy needs by basically turning the continent into one giant solar power plant.

    Europe is considering plans to spend more than £5bn on a string of giant solar power stations along the Mediterranean desert shores of northern Africa and the Middle East.

    More than a hundred of the generators, each fitted with thousands of huge mirrors, would generate electricity to be transmitted by undersea cable to Europe and then distributed across the continent to European Union member nations, including Britain.

    Billions of watts of power could be generated this way, enough to provide Europe with a sixth of its electricity needs and to allow it to make significant cuts in its carbon emissions. At the same time, the stations would be used as desalination plants to provide desert countries with desperately needed supplies of fresh water.

    Of course, one is compelled to wonder here what would happen if Africa provided Europe with all of its electricity?

    Most likely that won’t happen; no European countries would want to subject their whole energy security to regional volatility. On the other hand, one could imagine a fairly optimistic scenario wherein this energy cooperation would provide a stabilizing force to unstable states, help cure both continents’ post-colonial hangover, counteract China’s growing geopolitical influence in the region — and all the while reducing carbon emissions to zero.

    But, as always, what we are immediately most interested in is: in what ways would this energy pact be physically manifested in Africa?

    As but one illustration of how energy consumption is spatialized, there is the so-called mountaintop mining, whereby whole mountains are leveled off, literally grounded down, to get at coal deposits instead of using tunnels. The erased geology would then be dumped nearby, chocking streams and old growth forests.

    In one of the best (and certainly longest) articles on the subject that we have ever come across, Eric Reece, in Harpers Magazine, writes:

    Where once there were jagged forested ridgelines, now there is only a series of plateaus, staggered grey shelves where grass struggles to grow in crushed rock and shale. When visitors to eastern Kentucky first see the effects of this kind of mining, they often say the landscape looks like the Southwest – a harsh tableland interrupted by steep mesas.

    In other words, heating up your ex-urbian McMansion is right now turning Appalachia into Arizona and New Mexico.

    Lost Mountains

    One can easily picture Julie Bargmann and her D.I.R.T. Studio, like ambulance chasers circling a scene of devastation, salivating over photos of negative mountains, scheming away at plans to reclaim them from destruction, waiting for that commission.

    Unless, of course, Alan Berger and his Project for Reclamation Excellence (P-REX) don’t beat them to the job.

    But returning back to our question: what will Google Earth tourists see when they point their vigilant eyes towards an electrified North Africa? Will they come upon vast plantations of coronal fields, perfect geometries arrayed in similarly perfect arrangement, irrespective of terrain but nevertheless finely attuned to the sky?

    And what about the people on the ground? Where once was desert, might they now enjoy newly sprouted oases, which are fed with water from solar-powered desalination plants? An Emerald Necklace of Olmstedian design inscribed in the Saharan landscape.

    Will foreigners descend en mass to undertake a Bowlesian journey, trekking from one incomprehensible terrain to another equally unfathomable recess of the desert, utterly unprepared for the otherness of it all but obviously so seduced that they travel on, even while in the grips of dysentery, losing themselves psychologically and literally to the sands? All bearings and comfort are lost.

    Solar updraft tower

    And then just as things couldn’t get any stranger, they will come upon a stand of solar updraft towers; there are hundreds of them, possibly thousands, forming a kind of arid rainforest mechanically evapotranspirating.

    But in their parched and hallucinatory conditions these adventurers will mistake them for Persian tower tombs, divining the surrounding air into a vortex, the whirring blades resonating ghostly howls.

  2. How Big Companies Get Their Solar for Free

    How Big Companies Get Their Solar for Free


    It turns out that a lot of solar projects that big companies are putting together cost them absolutely no money! Actually, they often save them money from day 1. The question is, how are they doing it…and why can’t you and I do it as well?

    Solar power makes economic sense right now. If you install solar panels on your house in California, you will save money over the 25-year life of the panel (barring Steorn and cold fusion). But it’s hard to ask someone to pay 10 years of power bills all at once. In fact, it’s prohibitively expensive. Not even big companies (aside from the extremely high profit ones) have that much money to throw around.

    But investment companies do have that money, and if they can guarantee a 100% return over 25 years, then that’s a darned good deal for them, especially in light of the current credit crisis in America.

    Well that’s where MMA Renewable Ventures steps in. These guys link investors with companies who want solar panels. The investors pay for the panels and installation, and then charge the companies a locked rate for the power coming out of the cells. The companies save money on their power for the next 25 years, look green, and don’t have to lay out huge sums of money. The investors get a healthy return over the 25-year life of the cells and don’t have to worry much about risk.

    It’s a great deal, and already MMS has brokered deals for Gap, Estee Lauder and several other large companies.

    The question is, can the model be scaled down, so that you and I can get our solar panels for free too? Well, so far, it doesn’t make economic sense. But several companies are hungrily eyeing that space. And with a little bit cheaper cells, and a couple more government subsidies, we could all be enjoying free solar!

  4. Conserve Energy Or This Tree Gets It!

    Conserve Energy Or This Tree Gets It!

    Energytree 01

    That’s the concept behind Ben Arent’s Energy Tree. We’re accustomed to energy and power on demand. Anytime we need it, as much as we need, it’s there. The Energy Tree is supposed to change how we perceive energy use, more importantly how we should conserve it.

    The Energy Tree monitors your home and habits. Every bit of energy usage is noted and anytime the system feels you’re wasting energy, it does something morbid. It feeds the real live tree growing out of it with poison! The incentive here is be a good “green” go-getter and the tree gets water and nutrients. Be careless and wasteful and the tree slowly dies. Of course it might be hard to judge how well you’re doing without any actual data so the Energy Tree outputs all that info on a display. Now ask yourself how much energy is this Energy Tree using to do all this? It uses A LOT but all that energy comes from its built-in solar panel.

    I find the whole idea intriguing if not morbid. Any system designed to encourage certain behaviors and habits should do so thru positive reinforcement. We can learn new tricks but just like dogs, treats and praise are the keys to success.

  5. Serpentine Solar Boat To Set Sail

    Serpentine Solar Boat To Set Sail: “

    It is slow and travels only a short distance, but builders of the Serpentine Solar Shuttle say it’s the most advanced passenger ferry on British waters. Britain’s biggest solar-powered boat debuted Tuesday on a lake in London’s Hyde Park, opening what its developers hope is a door to the future of solar-powered transportation. The Serpentine Solar Shuttle – powered entirely by the sun – cruises at 5 mph and carries 42 passengers. ‘This is the most technologically advanced shuttle in the world right now,’ said designer Christoph Behling, who also designed the world’s largest solar boat in Hamburg, Germany.”

    The LumiWall: Solar Glass That Lights Up At Night:

    lumiwall2.jpg

    Imagine a roof that looks like shaded glass by day, but by evening is transformed into an array of white LED lights. Sharp’s LumiWall promises to do this, and it’s powered entirely by thin-film solar panels inside the glass. It’s kind of like a transparent, aesthetically-pleasing battery that gets charged by the sun. LumiWalls won’t really generate much electricity for your house, they are designed to be self-contained lighting devices. They will be available in 2007 according to Sharp. :: Via: The Green Guy
