Startups that help combat air pollution


Delhi residents woke up to a foggy morning, with many complaining about irritation in eyes and a cough, because of the air quality that plunged to the record low just a day after Diwali. The reason was a drop in wind speed, coupled with increase in humidity and low temperature, which worsened the situation and took the Air Quality Index (AQI) to the “severe” level, said air monitoring agencies.

Air pollution in India killed at least 6,00,000 people in 2012, said a World Health Organisation study in September. In all likeliness the number is going to increase by manifolds as the pollution level, mostly in North India, hit dangerous levels in October and November. While burning of paddy crops in the nearby states, Punjab and Haryana created a thick blanket of smog, Diwali’s extravagant celebrations made matters worse.

Breathing clean air is almost impossible under such circumstances. But there are a few startups that help in combating pollution by various methods. Techcircle lists various ways like indoor plantation, use of organic masks, installing air purifiers, choosing a long-term solution by going for solar powered electricals, all with the help of startups.

Big Question on Climate Crisis: How to Inspire Innovation


HAMBURG, Germany — On the edge of this northern German port city, the industrial giant Siemens is testing a way to offset the erratic nature of renewable power, by storing energy in hot rocks.

Off the coast of Scotland, an oil company will soon install the first commercial wind turbines that float in deep water, a potential clean-energy breakthrough that could be adopted around the globe.

And in Texas, an American company is about to test a new type of power plant that may generate electricity while cheaply capturing the emissions, allowing the climate-altering pollution to be pumped safely underground.

Around the world, energy innovation seems to be speeding up. Large historical forces are converging to create unprecedented turmoil and opportunity in what had long been one of the most hidebound industries.

The Health Benefits of Indoor Plants


When you think of a house plant, you probably think of a green plant that you water occasionally right? But did you know that those pretty green leaves can actually be beneficial to your health? Having indoor house plants can boost your physical, mental and spiritual health.

Many people thing growing indoor house plants is too much trouble so they turn to the silk variety for green foliage in their homes. But there really is a different in how your home feels when the plants are real. Did you know that living plants can actually improve the air we breathe? Green plants are known for removing carbon dioxide from the air, but they can also filter harmful toxins and pollutants as well. This will make the air in your home healthier for your family, which in turn can help to keep your family healthier as well!

2 billion children breathe bad air


Of the 2 billion children who inhale pollution, the daily breath of 300 million is toxic far beyond safe levels. It’s the most recent report highlighting the growing health problem air pollution poses.

Almost one in seven children worldwide live in areas with outdoor air so polluted that it can cause serious physical damage, including harming their developing brains, according to a study by the United Nations’ children’s agency UNICEF.

The study, released on Monday, uses satellite imagery to show for the first time how many children are exposed to outdoor pollution that exceeds global guidelines set by the World Health Organization (WHO), along with where they live across the globe.

We cannot survive without our oceans. We must act to save them  now!!


The oceans of the Earth can exist without us. If we humans become extinct, they won’t even notice we’re gone. We, however, simply cannot exist without our oceans. We need them. They are the primary life support system on Earth, the lungs, climate regulator, and ultimate food factory  connected deeply to each of us and nearly every economic activity that makes our world go round.

They provide 99% of the Earth’s living space and contain around 80% of all living organisms. They are the largest space in our universe known to be inhabited by organisms. They provide our Earth with a moist, livable climate, full of oxygen from trillions of microscopic plants floating like tiny stars in a watery, immense universe, producing close to 100 million tons of food each year, enough to provide one in every four or five people with their daily protein.

Air Pollution


Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution, some visible, some invisible that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution.

«Τριάντα χρόνια μετά το Τσέρνομπιλ»


Το καλοκαίρι που μας πέρασε, κλείσαμε 30 χρόνια από το τραγικό επεισόδιο στο Τσέρνομπιλ. Ωστόσο, αν και έχουν περάσει πολλά χρόνια, οι αρνητικές επιπτώσεις στο περιβάλλον κα στην υγεία είναι αισθητές μέχρι σήμερα. Παρακάτω, αναλύεται όλο το περιστατικό που οδήγησε σε αυτή την τραγωδία και πως συνεχίζει να μας επηρεάζει.

Ήταν τις πρώτες ώρες της 26ης Απριλίου του 1986, όταν μια κακότεχνη δοκιμή στο πυρηνικό εργοστάσιο της τότε σοβιετικής Ουκρανίας προκάλεσε την κατάρρευση που εξάπλωσε θανατηφόρα σύννεφα ατομικού υλικού στην ατμόσφαιρα, αναγκάζοντας δεκάδες χιλιάδες ανθρώπους να εγκαταλείψουν τα σπίτια τους.

Πρόκειται για τον Πυρηνικό Σταθμό Παραγωγής Ενέργειας του Τσερνομπίλ που βρίσκεται στην εγκαταλελειμμένη πλέον κωμόπολη Πρίπιατ της Ουκρανίας, ο οποίος είχε τεθεί σε λειτουργία το 1977, ως πρότυπο πυρηνικό εργοστάσιο για τη Σοβιετική Ένωση. Όμως, το βράδυ της Παρασκευής 25 Απριλίου 1986, ο διοικητής του ατομικού σταθμού «Β. Ι. Λένιν», όπως ήταν γνωστό το πυρηνικό εργοστάσιο παραγωγής ηλεκτρικής ενέργειας του Τσερνομπίλ, διέταξε την διεξαγωγή ενός πειράματος που θα ήταν μοιραίο για τον ίδιο αλλά και χιλιάδες ανθρώπους στην Ουκρανία (που άνηκε τότε στη  Σοβιετική Ένωση) και την Ευρώπη. Αυτό το πείραμα είχε ως στόχο την αύξηση της ασφάλειας του αντιδραστήρα 4, στην περίπτωση που για οποιονδήποτε λόγο εμφανιζόταν πρόβλημα στην παροχή ηλεκτρικής ενέργειας προς το σύστημα που ήταν επιφορτισμένο με την ψύξη του πυρήνα μέσω αντλιών νερού. Με λίγα λόγια, οι τεχνικοί θα επιχειρούσαν να αξιοποιήσουν τον ατμό που παράγει ένας πυρηνικός αντιδραστήρας, ακόμα και όταν είναι κλειστός για να παράγουν ηλεκτρική ενέργεια, η οποία θα κινούσε τις αντλίες που ήταν απαραίτητες για την διακίνηση των 28 τόνων νερού με τους οποίους λειτουργούσε το σύστημα ψύξης του πυρήνα όπου βρισκόταν το καύσιμο (ένα μείγμα ουρανίου-γραφίτη). Το πείραμα επιλέχθηκε να πραγματοποιηθεί στον αντιδραστήρα 4, διότι είχε κατασκευαστεί μόλις τρία χρόνια πριν, με ότι καλύτερο διέθετε η τότε Σοβιετική τεχνογνωσία. Σύμφωνα με το σχέδιο, αρχικά οι τεχνικοί κατέβασαν την θερμική ισχύ του αντιδραστήρα στα 700MW. Όμως, ο σχηματισμός μεγάλης ποσότητας του αερίου Xenon-135 οδήγησε στην περαιτέρω μείωση της ισχύος του αντιδραστήρα, καθώς το ισότοπο αυτό έχει την ιδιότητα να απορροφά νετρόνια. Όμως, ένας λανθασμένος χειρισμός των ράβδων ελέγχου οδήγησε σε μεγαλύτερη πτώση της ισχύος του αντιδραστήρα μέχρι που έφτασε στα 30ΜW. Αυτό είχε ως αποτέλεσμα τη μόλυνση του αντιδραστήρα με Xenon-135, και έτσι αποφασίστηκε να αφαιρέσουν τους περισσότερους ράβδους ελέγχου από τον αντιδραστήρα, χειροκίνητα, προκειμένου η ισχύς να επανέλθει σε επιθυμητά επίπεδα. Ευτυχώς, με αυτόν τον τρόπο, η ισχύς ανέβηκε στα 200 MW αν και το προβλεπόμενο που έπρεπε να επιτευχθεί ήταν στα 700MW.

Donald Trump would ‘cancel’ Paris climate deal


Republican presidential nominee Donald Trump has said he would “cancel” the Paris climate deal in his first major speech on energy policy.

More than 195 countries pledged to reduce carbon emissions in a landmark agreement last year. The billionaire businessman has said before there is no evidence that humans are responsible for climate change. He called for more drilling, fewer regulations and the approval of the Keystone XL oil pipeline from Canada.

Air Pollution for Kids


You will learn about “Air Pollution” in this video. Cutting of trees is one of the major reasons of air pollution. Air also gets polluted due to the smoke released by many factories and industries. Burning of wood and fossil fuels is another reason of air pollution. Also, vehicles such as cars, buses, trucks etc. give out a lot of smoke that pollutes the air. Due to air pollution, human beings suffer from a number of diseases like asthma, bronchitis, cancer, skin diseases etc.

Air pollution also affects the growth of plants and causes damage to our beautiful historical monuments. As responsible citizens, it is necessary to take up some preventive measures to reduce air pollution and its effects. We must plant more trees, avoid bursting firecrackers, make more use of public transport and ensure that regular servicing of our vehicles is done. Lastly, factories and power plants should also be set up far from residential areas, which will help in reducing air pollution.
