Greece Could Seize Personal Assets; Portuguese banks gamble with government debt - ValueWalk Greeks have to declare all their wealth From January 2017, 8.5 million Greek citizens have to file a declaration of their belongings. The government is on the hunt for real estate, jewellery, art and even cash – outside the banking system. Before government implements new tax, a directory of the soon-taxed wealth has to be prepared. Rating agencies – economic weapon of the USA Far from being news – the US uses rating agencies as a weapon of economic warfare against countries trying to become independent from the superpower. How to distinguish an attack from yet another revision of credit risk? Tourism is one of the key sectors in Turkey’s economy.

Cooperation of this alliance is also visible in the South China Sea. Governments tell people to stockpile food and water

Artificial photosynthesis breakthrough turns CO2 emissions into plastics and biofuel Scientists at the Lawrence Berkeley National Laboratory and the University of California, Berkeley have created a hybrid system of bacteria and semiconducting nanowires that mimics photosynthesis. According to the researchers, their versatile, high-yield system can take water, sunlight and carbon dioxide and turn them into the building blocks of biodegradable plastics, pharmaceutical drugs and even biofuel. Although renewable energy is making up a growing portion of the world’s energy production, scientists have suggested that the current trends of CO2 buildup in our atmosphere are still likely to lead to serious consequences, and do so sooner than we had anticipated. One way to keep harmful emissions under control could be to trap the CO2 coming out of smokestacks using materials like polymers or sponges. Taking inspiration from Mother Nature, scientists have now devised a system that uses sunlight and water to convert carbon dioxide into a wide range of useful chemicals. Source: LBNL

Do You Know How Residential Wind Turbines Operate? Residential Wind Turbines Aren't Complicated, You Just Need To Learn! Residential wind turbines are actually taking off in recognition. The commercial version has been around for a while, but it's's only been lately the technology has become available for individual householders. You can get them already made, or you can make one yourself. Using the power from your turbine can drastically lower your power bills, or perhaps eliminate them altogether. The characteristic size of residential wind turbines is sufficiently little to fit nicely in most back yards. 7 to twenty-five feet in diameter is common. But how do they work? With the price of energy getting dearer every day, doing whatever you can to save cash is usually a good concept. For more information, check out these sites: You Can Easily Figure Out How Residential Wind Turbines Work!

Among other things, the sunlight that pours through them can raise the temperature in the office, causing the air conditioning to come on. The facade was developed via a collaboration between Fraunhofer and the Weissensee School of Art in Berlin. Based on a concept by design student Bára Finnsdottir, it's composed of an array of circular flower-like components. In the case of the facade, that heat comes from direct sunlight. According to Fraunhofer, the facade could be retrofitted to existing windows, either on the surface of the glass or between the panes (in the case of double-paned windows). A working prototype of the technology will be on display from Apr. 13 to 17, at the Hannover Messe industrial trade show. Share
