Nuclear energy is the most malevolent and  righteous  source of energy known to humanity. From a destructive force in Hiroshima and Nagasaki to the only non-carbon emission energy source that has the potential to provide energy needs for the world. Nuclear energy is the most frustrating and confusing element of the energy mix. Recently the Green New Deal advocate Alexandria Ocasio-Cortez  said , "Green  New Deal does leave the door open for nuclear (energy)”.  Now the International Atomic Energy  Agency ( IAEA) projection  shows  an increase from 2016 levels by 42% in 2030, 83% in 2040, and 123% in 2050 . But why exactly was the door closed for nuclear in the first place and why has it opened now?   The story of nuclear energy started during World War 2. The USA in a joint operation with Canada and the United Kingdom started the Manhattan Project ,  followed by its use on Japan during 1945. Then in 1959, IAEA is created under the United ...

1. Air-ink - Image from Air-Ink is ink made out of air pollution. This project addresses major threats of air pollution, which kills more than 4 million people every year and costs 5 trillion dollars to the global economy. Global warming potential of carbon PM 2.5 is 450 times higher than CO 2 . Graviky Labs upcycle carbon emission and turn them into useful ink, offsetting environmental footprint. Anirudh Sharma founder of Gavikay Labs started this idea of capturing soot in Mumbai's polluted air and converted it into ink that could be used in reusing pollution endlessly. They developed a device that can be fitted to exhaust pie of car portable generator, the diesel engine, chimney, household vacuum pump, etc. and mix soot with solvent producing bottled ink, marker, spray cans, oil-based paints and pens. This company provided ink for painting exhibitions in Singapore and Dubai. Many artists like Kristopher Ho have made significant paintings from this ink. Winner of MIT solve, Shel...

Due to coronavirus, many wildlife species have taken over the busy empty roads. From goats conquering empty British village streets to monkeys in cities of Thailand. There has been a clear decrease in emissions of  NO2. All the significant emission industries are related to the fossil fuel industry. The transportation lockdown and a decrease in production due to lack of consumption have had a significant impact on climate around the world. Increase in air quality in Bejing and some parts of Europe are definitely due to restrictions of coronavirus. Tourist hotspots, like Venice, which normally overflooded with tourists and boats in canals is nearly empty and has clearer water. Aircraft industry which is responsible for 7% greenhouse gas emission has become lifeless. People in the short term have started to breath better air but the question is for how long.  This image was captured by NASA How would have imagined a disease in just 4 months of human transmission compl...
