Vinaytakbhanu posted a question In Suville, Spain an idea is in store to develope a 300MW solar power plant to power the entire city by 2014. The sun light is reflected and concentrated to a central tower which will be using molten salt, that makes energy storing longer than in the usual tower. In a 11 MW solar power plant the tower temperature is at 500 degree Celsius. Without any doubt there is no gas emission but the concern is would it raise the temperature on earth, eventually assisting to global warming? 1 year ago

Thatz a brilliant effort by the Spanish people ... But I'm afraid that it wont induce global warming as the rise of temperature if molten salt wont hav any effect on the EArth ....

Bio-energy and bio-fuels are a crucial part of the solution to climate change and peak oil, along with other forms of renewable energy, energy conservation and carbon capture and storage. Biomass is (in the Netherlands) the most cost-effective source.

It is. Infact, Veridium technology has a patent on technology that converts exhaust carbon dioxide from fermentation stage of ethanol facilities into new ethanol and biodiesel. Veridium's bioreactor is based on a new strain iron-loving blue-green algae, discovered thriving in a hot stream at Yellowstone National Park. The algae use the available carbon dioxide and water to grow new algae, giving off pure oxygen and water vapor in the process. Once the algae grow to maturity, they fall to the bottom of the bioreactor where the algae can be harvested for other uses several times per day. One such use is conversion into clean fuels such as ethanol and biodiesel.

Yes. It has been observed that algal strains such as Euglena gracilis, Galderia sp. and Viridella sp., which grow in acidic condition capture carbon more efficiently than the basic strains such as Chlorococcum and Synechococcus lividus.

Arunpillai shared a picture NASA Finds 2011 Ninth-Warmest Year on Record 5 months ago
The global average surface temperature in 2011 was the ninth warmest since 1880, according to NASA scientists. The finding continues a trend in which nine of the 10 warmest years in the modern meteorological record have occurred since the year 2000.
The comparison in the image shows how Earth continues to experience warmer temperatures than several decades ago. The average temperature around the globe in 2011 was 0.92 degrees F (0.51 C) warmer than the mid-20th century baseline.

Divyajeychandren wants to discuss Apa Sherpa on 1,700 kilometers of the Great Himalaya Trail in 120 days 5 months ago
When Apa Sherpa was introduced at the Parliament as someone who had climbed Mount Everest 19 times (since then he has climbed two more times), there was an instant pin-drop silence in the gathering followed by a long applause and a standing ovation.
That is the power of the Himalaya. That is the charm of our hero Apa Sherpa, known in the wider world as Super Sherpa.
Only a couple of months before Copenhagen, thanks again to Apa’s efforts, the campaign had reached out to President Barack Obama in New York.
This time, carrying some pebbles from the top of Everest as a memento, a reminder to him, and through him to the world that global warming is robbing the Himalaya of its constant companions – snow and water. And this should not just worry the Himalayan communities.
It is a clarion call to billions living on both sides of this greatest mountain range on earth that depend on the freshwater provided by it. The world had to pay attention.
And attention, they did pay. Global media of the likes of CNN, BBC, NHK, Guardian, Time,– all wrote and talked extensively about the challenges of the Himalaya.
It was possibly the biggest media coverage any Nepali campaign had ever accomplished.
Yet when it came to doing something about the cause, Copenhagen turned out to be a complete disappointment. So were the Climate Conventions at Cancun, and more recently in Durban, South Africa.
One of the reasons why the Himalaya do not get the requisite attention in global climate debate, despite holding such significance for the humanity, is the lack of science, and compelling research and stories. More importantly, it is the lack of effective articulation of the same by the mammoth Nepali contingents that flock every climate convention.

Divyajeychandren wants to discuss Global warming could make chocolates expensive - The Economic Times 6 months ago
A new study commissioned by the Bill & Melinda Gates Foundation has found that prices of chocolates could go up due to global warming. The study of cocoa plantations in Cote d’Ivoire and Ghana, where more than half of the world’s cocoa is grown, found that the amount of land suitable for production could halve due to temperature rise of just 2.3 degree C by 2050.
Cocoa trees need a cool climate to thrive and could be moved further up into higher land but since West Africa is fairly flat the potential for this is limited. The study proposes finding new heat and drought resistant crops and growing more cocoa in the shade. Other products reportedly affected by climate change include French wine, and Italian pasta.

This projection is only for plant species apparently. I think this part of the article might explain this projection better: "The researchers found a shift of biomes, or major ecological community types, toward Earth’s poles – most dramatically in temperate grasslands and boreal forests – and toward higher elevations. Ecologically sensitive “hotspots” – areas projected to undergo the greatest degree of species turnover – that were identified by the study include regions in the Himalayas and the Tibetan Plateau, eastern equatorial Africa, Madagascar, the Mediterranean region, southern South America, and North America’s Great Lakes and Great Plains areas. The largest areas of ecological sensitivity and biome changes predicted for this century are, not surprisingly, found in areas with the most dramatic climate change: in the Northern Hemisphere high latitudes, particularly along the northern and southern boundaries of boreal forests."

Divyajeychandren wants to discuss 5 Wacky Ways to Fix the Planet 6 months ago
With heat, tornadoes, drought, fires, extreme weather and flooding, the climate has certainly caught the world's attention in 2011. While scientists debate just how much the world is warming and how much of that has to do with human impact, others are taking it upon themselves to reverse the changes through technology. Here are five schemes that may seem pie-in-the-sky at first, but could soon have a big impact on our planet:
1. Make it rain- Seeding the skies to grow more crops.
2. Who let the CO2 out?- Trying to scrub the air is much more expensive than keeping it from getting dirty in the first place.
3. Everything’s better under the sea- The idea of taking trapped carbon and storing it far underneath the ocean floor.
4. Power your house with your car- A Smart Home Charging technology designed to encourage consumers to move away from using electricity provided by the main grid and use their car for more than just motoring.
5. Stink things up- Smelly algae has potential as a power source. It takes what we generally think of as waste — be it sewage, C02 emissions or, fertilizer runoff — and uses it to grow. Oil can then be separated from the algae and used as a biofuel.

Divyajeychandren shared a picture Coral bleaching 6 months ago
Coral bleaching occurs when, due to stress, the coral expels the zooxanthellae algae with which it has a symbiotic relationship. This stress can come in the form of higher water temperatures, increased solar radiation, ocean acidification, and a loss of food in the form of zooplankton due to overfishing.
The term "coral bleaching" was coined because the algae gives the coral its color, thus when the algae is expelled, the coral loses its color. Without the algae the coral cannot survive, leading to a chain of events which can leave areas of ocean lifeless. Coral is the major backbone of many ocean ecologies, and if it dies then many other life forms in the area may leave or die as well. -

Answer this question / Share a linkFollowing is some knowledge gained from on experimentation on algae at domestic level in PET bottles & small plastic cans. 1.I occasionally use small air pump used in domestic aquariums which gibes good bubbling air flow and costs only Rs 100 say US$ 2; 2. Conversion of algae to organic manure is quite fast (say in 1-2 Days) using associated boi-sensitiser culture made from domestic kitchen waste. Good fraction of the nutrients remain in aquas phase and appear to be very effective apparently due to aquas & micro in nature. 3. Leave tap water in a plastic transparent bottle (say of Bisrely) in sun for few days. I would observe growth of algae at bottom of the bottle which is perhaps the most prevalent in the local environment. This algae can be further multiplied in a open can left in sun. 4. Experimentation at domestic level is enjoyable like kitchen gardening. .Initially depend on physical observation.rather than chemical lab tests. Arjun
