With increasing levels of harmful gases being released into the environment, the future, indeed, looks bleak.

Well, what about if we could ‘revamp’ those harmful gases into some highly useful things, like biofuels  or plastics?

The good thing is that a group of researchers have essentially taken cues from Mother Nature itself, and thus accomplished the impossible!

By the way, how have the scientists managed to achieve such a remarkable feat?

Here’s how:

The researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California, Berkeley, have developed the revolutionary system which essentially mimics photosynthesis.

The system collects Carbon Dioxide and other greenhouse gases before they are let loose into the atmosphere and converts them into acetate, a basic building block for organic compounds.

Then, the acetate can be used to manufacture a diverse array of chemicals, drugs and alternative fuels.

All this is done through creation of an ‘artificial forest’ of Silicon and Titanium Dioxide nanowires, which are seeded with bacterial populations.

Scientists believe that system has the potential to revolutionize the chemical and oil industry. The system can produce chemicals and fuels in a totally renewable way, rather than extracting them from deep below the ground.

So, is it time to say goodbye to greenhouse gases?

As of now, the system boasts of an efficiency of 0.38 per cent, close to the natural process of photosynthesis. However, researchers believe that soon they would manage to increase it to 3 per cent. And, the system would be embraced on a large scale once it begins to gain traction.

“Once we can reach a conversion efficiency of 10 per cent in a cost-effective manner, the technology should be commercially viable,” said Christopher Chang, a chemist and biosynthesis expert.

The environment can hopefully breathe easy now.

U.S. Pentagon Emits More Greenhouse Gases Than Portugal, Study Finds

The Pentagon, which oversees the U.S. military, released about 59 million metric tons of carbon dioxide

The United States creates more planet-warming greenhouse gas emissions through its defense operations alone than industrialized countries such as Sweden and Portugal, researchers said Wednesday.

The Pentagon, which oversees the U.S. military, released about 59 million metric tons of carbon dioxide and other greenhouse gases in 2017, according to the first study to compile such comprehensive data, published by Brown University.

The Pentagon’s emissions were “in any one year … greater than many smaller countries’ greenhouse gas emissions,” the study said.

If it were a country, its emissions would make it the world’s 55th-largest contributor, said Neta Crawford, the study’s author and a political scientist at Boston University.

“There is a lot of room here to reduce emissions,” Crawford said.

Request for comments to the Pentagon went unanswered.

Troop movements

Using and moving troops and weapons accounted for about 70% of its energy consumption, mostly due to the burning of jet and diesel fuel, Crawford said.

It dwarfed yearly emissions by Sweden, which the international research project Global Carbon Atlas ranks 65th worldwide for its of CO2 emissions.

Pentagon emissions were higher than those of Portugal, ranked 57th by the Global Carbon Atlas, said Crawford.

China is the world’s largest emitter of carbon dioxide, the main gas responsible for climate change, followed by the United States.

The Pentagon called climate change “a national security issue” in a January report to Congress and has launched multiple initiatives to prepare for its impact.

Global temperatures are on course for an increase of 3 to 5 degrees Celsius (5.4-9.0 degrees Fahrenheit) this century, far overshooting a global target of limiting the increase to 2 C or less, the U.N. World Meteorological Organization said in November.

Four degrees Celsius of warming would increase more than five times the influence of climate on conflict, according to a study published in Nature magazine on Wednesday.

Improvements

Crawford said the Pentagon had reduced its fuel consumption significantly since 2009, including by making its vehicles more efficient and moving to cleaner sources of energy at bases.

It could reduce them further by cutting fuel-heavy missions to the Persian Gulf to protect access to oil, which were no longer a top priority as renewable energy gained ground, she said.

“Many missions could actually be rethought, and it would make the world safer,” she said. (VOA)
