The largest working hydro-electric wave energy device was launched by Queen’s University Belfast, Aquamarine Power Ltd. and the Scottish government recently, bringing the global wave energy industry one major move forward.

The device is called Oyster. It is the only hydro-electric wave energy device producing power in the world, according to Queens University Belfast.

How does it work?

As scientists continue to show, the oceans absorb CO2 and keep it from going into the atmosphere. Thus, they help to protect against global climate change. However, this is looking to be perhaps an even bigger problem than climate change!

When oceans absorb this CO2, it makes them more and more acidic. “Since the industrial revolution, the ocean acidity has increased by 30%,” according to Lisa Suatoni, Ph.D. If we continue polluting CO2 as we are now, “ocean acidity will double by the end of the century compared to pre-industrial times. That is a big problem.”

A beautiful short video of the issues related to this, the oceans, and the challenge we are facing follows. It includes commentary from leading scientists and narration by Sigourney Weaver.

One of the best videos I’ve seen in a long time!

Irish scientists have discovered that adding just a small amount of fish oil to the diet of cattle can vastly reduce the amount of methane produced by, ahem…cow farts.

Climate scientists have long known that, pound for pound, methane is 20 times more powerful than carbon dioxide at trapping the suns rays, making it a highly potent greenhouse gas. An incredible 900 billion tonnes of the noxious fumes are produced each year by methanogen bacteria that live in the digestive systems of ruminants such as cattle, sheep and goats.

US Scientists have revealed how natural gas locked up in frozen water crystals could provide massive amounts of energy, and claim that it could even be totally emissions-free.

The astonishing claim was made by Tim Collett of the United States Geological Survey at last weeks national meeting of the American Chemical Society. Collett told the gathering that, to the naked eye, clathrate hydrate (CH) looks like everyday ice but, as well as being partly made of water, the molecules are also organised into “cages”, which trap individual molecules of methane.

Remarkably, a new method of extracting the methane and ’swapping’ it with carbon dioxide could turn the substance into a revolutionary carbon-neutral fossil fuel.

China has announced plans to take on the US head-to-head in the race to develop low emission vehicles, with a massive $2.2 billion investment in electric cars over the next three years.

The news comes hot on the heels of President Obama’s announcement of a whopping $2.4 billion investment in electric vehicles in the United States.

The Chinese government hopes that the investment will help the country to make 500,000 all-electric and hybrid vehicles a year by 2011 - and encourage organizations like city governments and airport taxi firms to enjoy subsidies of more than $70,000 on fleets of new vehicles.

Scientists at the Lawrence Berkeley National Laboratory in California have suggested a plan to drastically reduce global warming, by painting the world white.  If implemented successfully, it would be the equivalent of taking the world’s 600 million cars off the road for 18 years.

Hashem Akbari and Surabi Meno, along with Art Rosenfeld, California Energy Commissioner and Professor Emeritus at the University of California, Berkeley, are so convinced that their idea will work, that they have proposed a “Cool World” plan that would use white roofs, and solar-reflective roofs of other colors, to reduce greenhouse gas emissions and help delay atmospheric heating effects.

Korea’s rapid industrialization can be felt everywhere, from the coastal landscapes, which are dotted with factories, to the large cities–Seoul, Busan, and Daegu–which often have air quality so poor that skylines are swallowed in smog.

Now, the outgoing government of Korea has passed new legislation to combat this pollution and join in the international battle against climate change.

The aptly named “Act on Climate Change” will establish an emissions trading market, raise the bar for renewable energy, assist in reducing industrial, home, and vehicle emissions, and increase carbon capture.
