BBC Asteroid Impact Simulation End Of The World Predictions
A huge asteroid with a diameter of 500 Kilometer is going to impact on Earth! Destination: Pacific Ocean. The asteroid impact peels 10 kilometers crust off the surface of Earth. The resulting shockwave travels at hypersonic speed. The debris from the impact is blasted to the lower orbit of Earth, and they returns to destroy everything on the planet. The firestorm created by the asteroid impact encircles the Earth,
vaporizing everything in our world. Within 24 hours of asteroid impact, the entire Earth will be uninhabitable. The researchers have found that this scenario has happened 6 times in Earth's history.
Worlds Largest Wind Farm Chinas Future MEGAPROJECTS Part 6
By now you're seeing the trend here: theworld's biggest city, the world's longest canal, biggest airport, longest high speedrail network and underwater tunnel. So the fact that China is building the world'slargest Wind Power Farm too shouldn't surprise you. The Gansu Wind Farm Project will produce20 Gigawatts of power by 2020, and will cost nearly $20 billion to build. Turbines aregoing up at the staggering rate of 35 per day across the three areas that make up thepower base. In 2012, Gansu's capacity surpassed the total windgeneratedelectricity producedby all of the United Kingdom, and it's just the largest of six megawind farms currentlyunder construction throughout China.
But China isn't embracing wind just to reduceits carbon emissions, it's doing everything it can to simply keep the lights on. Someparts of the country with booming middle class populations suffer persistent electricityshortages because, just like us, people want refrigerators, dishwashers, washer and dryers,and computers in their homes, but there's only so much energy to go around. So China's State Council is pushing foran acrosstheboard renewable strategy to reduce its dependence on oil, coal and gas,the finite resources of the 20th century whose extraction and consumption are subject toconstant geopolitical tensions.
Since 2013, China has led the world in renewableenergy production, with a total capacity of 378 installed Gigawatts, coming from projectsas wideranging as Gansu to hydroelectric power plants like the Three Gorges Dam, whichspans the Yangtze River and is the world's largest power station of any kind. In justthe last 10 years, China has increased its solar panel production 100fold to becomethe world's leading manufacturer of the technology. With China now pumping more CO2 into the atmospherethan the number two and three emitting countries the US and India combined, it's vitalfor the future of the planet that it continues

How Giant Wind Farms Can Save The Planet
There now appears to be a way to kill a hurricane'spower by transferring its energy into electricity. According to his advanced climateweathercomputer model, Stanford researcher Mark Jacobson found that installing massive offshore windturbine farms in the path of a hurricane diminishes hurricane wind speeds by up to 92 mph andstorm surge by up to 79%. The catch is that the simulation used300 Gigawatts of installed wind turbine capacity, when the biggest offshore wind farm man hasbuilt to this point is the London array at only 630 Megawatts of installed capacity,nearly 500 times smaller than the one Jacobson used in the model. Plus, the London Arrayalso cost $3 billion. So, scaling up to a
wind farm the size of which was used in thestudy would cost hundreds of billions of dollars. But think of the different problems this couldsimultaneously eliminate. Hurricane Sandy caused over $80 billion in damages as didKatrina, which basically wiped out New Orleans. With climate change making these storms moreintense and more frequent, one idea to protect cities has been the construction of giantsea walls at a cost ranging from $1030 billion per city. But a giant wind farm could protectentire coastlines, while paying for itself through the energy it produces and CO2 emissionsif reduces. A 300 GW arraylike the one in the study would create enough electricityto power around 100,000,000 homes. If building
one of these mega farms in the gulf coastcould simultaneously stop the threat of hurricanes in the region and provide the power for alarge portion of the country in a clean, renewable way, why would we not take a hard look atthisé If we're going to solve these big, 21stcentury problems, we need to start thinkingboldly. We should build off Mark Jacobson's study with a much more indepth examinationto both confirm these findings and to make sure that stopping hurricanes wouldn't haveunintended negative consequences on the ecosystem more broadly. But if the data continues tolook as good as it does right now, I say we go for it and construct two, 300 GW arrays:one in the Gulf of Mexico and one off the
