5 . Called ocean thermal energy conversion (OTEC), the idea is to use surface water warmed by the sun to heat a fluid such as ammonia or water, which then runs a heat engine to produce energy, just like a power plant driven by steam. Cold water from deeper layers of the ocean would then be piped up to cool the fluid and repeat the cycle. Theoretically, oceans could provide vast amounts of electricity like this. Researchers have estimated that there is enough ocean heat to supply 7,000 gigawatt s a year without affecting ocean circulation, enough to supply the world’s electricity demand— if we can access it.
The idea was first put forward in 1881, but went largely unexplored until the 1970s oil. crisis drove a search for new sources of energy. In the years since, demonstration projects have been built, but progress has been “disappointing”, says AI Binger at SIDS DOCK, an organisation that promotes clean energy development in small island countries. In recent years, a fresh urgency to transition away from fossil fuels has brought a suggestion of an OTEC return. “It’s the most promising it’s been in many decades,” says Andrea Copping at the Pacific Northwest National Laboratory in Washington state.
Tropical (热带的) islands are good candidates for OTEC because of their high energy costs— diesel (柴油) generators are common there—and the presence of deep cold water not far from shore, says James Van Zwieten at Florida Atlantic University. Islands also have less space for other types of renewables. A barrier for past projects was the cost of fixing kilometres of large pipes to reach deep water. Global OTEC aims to avoid that by extending a shorter pipe from a platform floating in deep water 10 kilometres offshore, then transmitting electricity back via a cable (电缆), and making use of advances made in offshore wind technology.
“OTEC will be part of providing a reasonable energy transition so these places aren’t depending on diesel imports from the richest petrol states in the world,” says Dan Grech, Global OTEC’s CEO.

6 . Four Useful Ways to Stop Comparing Yourself to Others
•Don’t compare your life to everyone else’s highlight reel (高光时刻). Are you ready for my most shocking observation yet?
•
•Have boundaries around how much time you spend on social media. Don’t follow any accounts that tend to make you feel bad about yourself. Set a timer and allow yourself to scroll (滚屏) for 30 minutes.
•Learn to compete with yourself instead of others. Instead of focusing on where you are compared to others, focus on your own goals. Where are you compared to where you were at this time last year? In the past year, you’ve learned, stretched, improved, accomplished and created.
A.Make them personal |
B.Focus on your strengths |
C.Love your imperfections |
D.Social media doesn’t always reflect reality |
E.When time is up, step away from social media |
F.It has been suggested to restrict it to only one hour a day |
G.Think about how much of that you’ve done in your lifetime |

8 . Vishwanath Mallabadi Davangere has a unique talent for turning abandoned items into amazing works of art. From metal and plastic to old devices and circuit boards, Vishwanath selects only the finest “good stuff” with potential for transformation.
Vishwanath’s father was a well-known sculptor and painter, but he had hopes of his son becoming a doctor. But Vishwanath had other ideas. He was fascinated with upcycling second-hand objects from a young age, and decided to pursue a Bachelor of Fine Arts in Applied Art. Even as a high-level administrator at Wipro, working in Talent Transformation, Vishwanath wouldn’t shake his passion for eco-art. In his free time and on the weekends, he devoted himself to experimenting with e-waste and creating one-of-a-kind masterpieces before retiring two years ago.
With India facing a growing e-waste crisis, producing 10.1 lakh tonnes in 2019-20 with only 22.7% recycled, Vishwanath’s passion for recycling is more important than ever. As he learned more about the harm e-waste was causing to the environment, he took his art to the next level creating paintings and sculptures that spread awareness about this urgent issue.
From computer keyboard keys to data cards and even wristwatch parts, Vishwanath has transformed over 500 pieces of e-waste into amazing pieces of art! He has created a six-foot-tall sculpture, eco-jewellery and even wearable art for a fashion show. One of his masterpieces—an awesome landscape—was inspired by Vincent van Gogh’s The Starry Night.
In just a few short minutes, he can turn pieces of e-waste into great pieces of jewellery. When it comes to sculptures, the process might take weeks or even months. But it’s all worth it because sustainable initiatives and upcycled art are fashionable these days. Companies everywhere are looking to adopt a more sustainable culture, and Vishwanath’s art is the perfect addition to any eco-friendly office or home.

9 . Australia Post is celebrating the 10th anniversary of BirdLife Australia’s Aussie Bird Count with three of our most commonly seen birds set to be flying across the globe on a commemorative stamp issue launch today.
Rainbow Lorikeet: Known for its kaleidoscopic colors, the Rainbow Lorikeet has been the number one most seen bird every year of the Aussi e Bird Count. These social and energetic birds are often spotted in urban areas, parks, and gardens, feeding on flowering native plants and spreading joy with their playful calls, though in cities to which they have been introduced such as Perth and Hobart their presence is not so welcome as they out-compete local parrot species.
Noisy Miner: As the name suggests, the Noisy Miners are highly vocal birds with a complex range of calls. They are skilled communicators, using a variety of sounds to defend their home and communicate with their group. These fascinating honeyeaters are essential pollinators, but the number of these bold birds has increased so much that they have started to drive away many of our smaller bush birds.
Australian Magpie: The iconic Australian Magpie, with its distinctive black and white feathers, holds a special place in the hearts of many Australians. Known for their beautiful, melodious song, magpies are highly intelligent and form strong social bonds. They are also famous for their swooping (俯冲) behaviour during the nesting season, as their protective instincts kick in to safeguard their weak chicks in the nest.
The stamp issue includes various products, such as the Aussie Bird Count First Day Cover (Gummed Stamps), the Aussi e Bird Count First Day Cover (Minisheet), and a set of three Maxicards, which can be used as postcards and posted worldwide. Starting today, the stamps are available for purchase through Australia Post’s official website: https://auspost.com.au//stamps.
