Air quality in China is bad, it’s really, really bad. The air quality is so poor that residents rarely see the sun and in some cities, the dense air pollution is mistaken for snow! What is causing all of the pollution? It’s coal-burning smog. And until China can ween itself from fossil fuels and implement more sustainable energy practices, other energy solutions are desperately needed. One designer named Daan Roosegaarde may have an ingenius solution.
Roosegaarde has an idea to create what he is calling an “electronic vacuum cleaner”. Copper Tesla coils buried underground would help to create an electrostatic field that would pull smog particles down from the polluted sky, creating a clear space above where sunlight could shine through.
His smog vacuum would attract pollution particles much like a strand of hair is pulled toward a statically charged balloon. Copper coils would create a field of static electric ions which would magnetize the smog, causing it to fall down to the ground below. Roosegaarde plans to capture all of the smog on the ground and compress it, hopefully making it easier to create awareness of how much smog residents are living with and to rally opposition to the causes of the polluted air.
This week Roosegaarde created a working prototype with the help of the University of Delft. They were able to take a 5×5 meter room full of smog and create a smog-free hole of one cubic meter with their device. Now the challenge is how to apply it on a grander scale. Roosegaarde would like to see it installed in parks and public spaces where everyone can enjoy a smog free sky.
Over the course of the next 12 to 18 months, Roosegaarde will be working to perfect his device and many will be watching, waiting, and hoping for his success. Roosegaarde acknowledges that the smog plaguing China is “a human problem not a technological problem” and he hopes that his smog-cleaning vacuum will help raise awareness off the issue while also taking a small step to make the air quality and quality of life a little better for the residents of China.
Elephants are being poached for their ivory at the highest rate ever recorded. Current estimates put the figure at 36,000 elephants killed annually, equating to one elephant dying every 15 minutes.
The International March for Elephants organized by iworry, a campaign by the David Sheldrick Wildlife Trust, was created to sound a warning that the future survival of elephants is in serious jeopardy.
Elephants share the same emotions as humans. They have a strong sense of family and mourn the deaths of their loved ones, just as we do. Elephants have unique personalities like us, too! They can be playful or mischievous; they can even hold grudges.
The David Sheldrick Wildlife Trust has learned the beauty of elephants first hand and they have also witnessed the terrible impact of the renewed ivory poaching that we are seeing today. In just 18 days in September, they were called on to rescue 14 orphaned elephants. To date, they have arrested 1,406 poachers and their veterinary teams have successfully treated over 500 wounded elephants.
The International March for Elephants is demanding stronger laws and penalties associated with wildlife crime in countries where poaching and ivory trafficking occurs; increased levels of investment in anti-poaching initiatives by international governments; increased diplomatic pressure on countries where elephants live; and pressure on those nations that fuel the demand.
In an op-ed published this month in the New York Times, Ralph Cavanagh, co-director of the energy program at the Natural Resources Defense Council, declares that our energy productivity and energy security are the best they’ve been since the 70’s. This opinion finds itself in stark contrast of those who think we need to construct the massive Keystone XL pipeline, or create a surge of oil and gas drilling, or start a nuclear power renaissance. Keep reading to learn more about Cavanagh’s article.
Cavanagh says that we have President Obama’s climate action plan to thank for the new-found positivity surrounding our nation’s energy news. Obama’s climate action plan gives top priority to the most productive and lowest-cost options for energy, which includes the “energy efficient resources” that come from getting more out of oil, natural gas and electricity with efficient equipment and vehicles that are used more carefully.
According to government data, energy-saving efforts in the U.S. have resulted in a steady decline in energy use since 2007. In 2012, energy use was lower than it had been in 1999, despite the 25 percent growth spurt the economy experienced since then. Cavanagh states that this trend is the result of factories and businesses producing more products and value with less energy, the main goal Obama’s climate action plan.
American oil use is also in decline, down 14 percent compared to a peak in 2005. The U.S. used less oil last year than in 1973, even though the economy is now 3 times as large as it was back then! This is thanks to better mileage from our vehicles and driving those vehicles less. Greenhouse gas emission, energy costs, and gasoline use have also declined; saving billions of dollars and helping the American economy compete in a global market whilst helping to make the U.S. more secure.
To continue this progress, Cavanagh says that the federal and state governments must keep increasing efficiency standards for buildings, equipment, and vehicles. And the Environmental Protection Agency must reduce carbon dioxide emissions from power plants by implementing standards that focus on energy efficiency to reduce pollution. He also states that utility companies should be rewarded by state regulators for helping customers utilize energy efficiently instead of penalizing those companies for not increasing their sales. Annual rate adjustments should be instituted by regulators to allow for unexpected changes in energy utility sales.
Over the past 40 years, the U.S. has found many innovative ways to save energy; we have more than doubled the economic productivity of our oil, natural gas and electricity. America’s most productive energy resource has been efficiency all along and it starts with the everyday decisions we make at home and at work. By simply trading out our old light bulbs for energy saving bulbs and updating our homes and buildings with energy-saving products and appliances, we will continue to see our energy productivity and energy security increase in America. If we focus on achieving more energy savings, we will also reduce costs and pollution. It seems the future of energy is not as dark as it once seemed.
The Dallas Zoo has just become the new home to two male cheetah cubs named Kamau and Winspear. Some day they’ll be able to go from 0 to 60 mph in 3 seconds but today they’re meeting their new best friend. To calm the naturally nervous and rambunctious cheetahs, animal care specialists are employing an effective tactic used by zoos; they’re pairing the cheetah cubs with a black labrador puppy.
The two month old lab puppy is named Amani, meaning peace in Swahili, and he will live with the cheetahs 24/7. According to the animal care specialists supervising their introduction, eventually the cheetahs will see the puppy as one of their own, or part of their “coalition”. The dog will be a calming influence on the big cats insuring that they are relaxed enough to be taken into public.
The cheetah cubs are now part of the Dallas Zoo’s Animal Adventures program designed to educate the public about highly endangered species. The traveling outreach program exposes audiences to 30 different animals including a variety of birds, mammals and reptiles. Cheetahs could use the exposure. With less than 10,000 cheetahs in the wild, it is extremely important to educate the public on the beauty of the cheetah and to inspire communities to help protect them.
