What kills roughly 2 million people but is not AIDS? Answer: indoor cooking related diseases. Shocked? This fact is found and recorded in a World Health Organization report. The problem aggravates in villages where modern gas burners are rarely available and the smoke chullas (stoves) are vicious enough to choke your lungs!
In an attempt to alleviate this situation, students from MIT have designed a clean solar cooker out of yak-wool canvas panels, for villagers of the Himalayan region. The panels are stretched over bamboo ribs and faced with reflective Mylar in a manner that in first look you might think it to be some sort of an umbrella!

But this unique light weight cooking device comes for only $17 and for an extra $26 one can attach a metal coil for heating one’s house. This solar cooker helps in cutting down carbon emission as opposed to the traditional yak dung or wood fuel the cooker uses solar power to make yummy food! Its design has won a prize and loads of public attention at the MIT IDEAS competition and in near future one may happen to find it in markets for sale. This means clean and green cooking at an affordable price and no more choking or coughing over horrible gas stoves!

Scientists and environmentalists from world over have expressed their concerns over the far-reaching devastating effects of rapid destruction and drying of wetlands.
Gathered at the 8th INTECOL International Wetlands Conference (Cuiaba, Brazil), some 700 experts from 28 nations believe that quickly drying up wetlands invariably lead to climate change via global warming.
Wetlands store a vast amount of carbon (in form of CO2). Their complete destruction will lead to massive release of this stored up CO2 into atmosphere, thereby heating it up. Besides, carbon dioxide other greenhouse gases like methane (more potent than the former) will also be released which will further strain our Earth’s atmosphere.

It is interesting to note that, wetlands (including peat bogs, swamps, river deltas, marshes, mangroves, tundra, lagoons and river floodplains cover only 6% of Earth’s land surface. But, they store upto 20% of its terrestrial carbon! According to an estimate these waterlogged areas contain nearly 771 billion tonnes of greenhouse gases (this is equivalent to present-day carbon levels found in atmosphere).

It ‘a small revolution that could increase the efficiency of solar panels and therefore energy efficiency. He discovered the team of prof. Mark Baldo at MIT: The secret is in a paint organic nature that should be applied on glass surfaces and allows the capture of infrared and ultraviolet rays that trapped in glass, which became like a big slab of fiber optics, flowing outwards. In practice, solar cells are only at the central part while the broader is covered by paint, currently stabilized at 90%, which provides for the capture and dissemination. We see a little ‘more in detail as is the process:

What ago. It ‘been shown a significant improvement at low cost in the provision of solar concentrator. With the new device the power produced by a solar cell increases by 40 times without the need to track the sun.

Why is it important? The sun is an inexhaustible source of clean power. The major obstacles to wide
dissemination of solar power systems are due to costs. With this system will improve performance and lower costs.

Rising CO2 levels is just not a nuisance for those living above the seas but for those dwelling underneath oceans as well. So far, the focus is shifted more towards the implication of increased levels of this gas in atmosphere; concerns on Global Warming thus being voiced by Governments and Public alike every other day. But oceanographers have warned that there’s another reason to check our carbon emissions as more carbon dioxide in the air means more of it in our oceans and seas. Most of us don’t realize that oceans are the absorbing-pits of this green house gas. As per an estimate, the world’s oceans have absorbed 40 percent of the carbon dioxide emissions produced by humans in the industrial age. And more and more CO2 in oceans is becoming a threat to Coral reefs - nature’s most lively and intricate architecture. Since the time Earth’s landscape comprised of nothing more than huge primordial soup in hot water bodies, these corals are being formed and today they are important for the healthy survival of other marine flora and fauna.

Tuatara, the ancient reptile found in New Zealand is under survival threat from none other than global warming. Also, known as a “living fossil” / “living dinosaur”, this reptile has lived on our planet from the past 220 million years! That’s quite a long time. But now, this endangered animal known for its “spiny back” is facing extreme pressure on survival front due to rising global temperatures. The phenomenon of climate change has started showing its true colors in various parts of the world now. In wake of an impending threat to humans due to catastrophic events popping out as a result of both global warming and climate change, one can only imagine what little chance a reptilian species has! Tuatara is one of the oldest and relatively un-evolved species alive today. Commonly mistaken for lizards or mini crocs this animal is very different from the two and has a very primitive bone structure.

Reptiles as such are known for their sensitivity to thermal changes. Mostly being endothermic or cold-blooded creatures, the population of reptiles faces a challenge when their breeding cycles get disturbed owing to fluctuations in temperature. Something similar is happening with this New Zealandian reptile as well. Australian researches predict that with every 3-4 degree rise in air temperature the tuatara will only be able to produce male offspring by 2085. This means complete wipeout of females of the species! The researchers say their finding highlights the need for ways to predict climate change impacts in animals where sex of the offspring is determined by temperature.

It ‘was inaugurated yesterday the first mini - a condominium zero emission type passive constructed Angels Rosora in the province of Ancona. The building has six apartments and condominiums that dwell there, employees of the group Loccioni, will become part of the project LEAF (Life Energy and Future), the community that will live using only the energy that comes from natural sources and solutions and technological domotiche highest level.

The idea was born at home Loccioni, a company that deals directly domotics which also took part Enel, Whirlpool and Cisco. The building was built with the direction south, but also has a storage system for hydrogen or appliances with very high efficiency. The walls are insulated to retain the heat in winter and cool in summer.
