For years climate change has been blamed on global warming, which has in turn been blamed on green-house gases produced from the combustion of fossil fuels. However there is another explication that perhaps can’t be held culpable for all changes affecting the global environment at the moment, but it certainly doesn’t improve the situation.
On July 14th 2010 it was officially revealed that information from the Voyager 1 and Voyager 2 satellites prove that our solar system is passing through an interstellar cloud of electrical energy. According to astrophysicist Alexei Dmitriev the energy in the cloud is being absorbed by the sun, causing it to be more active and in turn give off much more energy. It is also exciting the atmospheres of the planets, and has been proven to have dramatically affected the weather here on earth and increase the likelihood of earthquakes. The cloud is vast and it is predicted that we may not leave it for another 2000-3000 years, although the worst is expected to pass in the next few years. http://oilprice.com/Environment/Global-Warming/Interstellar-Energy-Cloud-may-be-as-much-to-Blame-for-Climate-Change-as-CO2-Emissions.html
The worldwide movement toward sustainability has made significant progress over the past half-dozen years as companies and cities have pursued strategies that balance future and current societal needs.
Now, sustainable development is entering a new phase, characterized by greater alignment within and between the public and private sectors.
Perhaps the greatest obstacle has been the lack of consistent and comparable standards for defining and measuring sustainability. Although these issues have yet to be fully resolved, many well-coordinated initiatives in recent years have pointed the way forward for companies and cities.
Today, wind power is often tapped from stationary structures– windmills — to power stationary buildings. But a group is out to prove that wind could power a moving vehicle — and push it faster than the wind is blowing.
If it seems counter-intuitive, you’re not alone. Many scientists dismiss the idea as fantasy, most believing the wind could not push a vehicle faster than the wind is moving, as that would border on perpetual motion. http://tpt.to/a2bQpKZ
Why we are asking this now?
Piezoelectric generators are electricity generation device based on piezoelectric effect. The piezoelectric current is generated when a mechanical force applied on a body is converted to electric potential. In simple words, it means that whenever a piezoelectric material is deformed it generates electric current that can be harnessed by the means of capacitors and electrical circuitry. Many piezoelectric materials are already in use in transformers and various electrical components. It finds extensive use in motor manufacturing, motion sensors and even land mine devices used as weaponry all over the world. There are numerous other applications of piezoelectric effect. It can be used to make piezoelectric generator for charging smaller appliances or even running your watch. If it is fitted in your shoe then it can power your gadgets with every step you take.
The demand to adopt greener sources of energy in everyday life has prompted many architects to design skyscrapers which can use the renewable sources of energy. The roofs of these buildings use sunlight and other green sources of energy. Here is a list of 10 sustainable skyscrapers designed to have green roofs:
