2 . 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.

4 . Welcome to Buckler’s Hard
Fun facts about Buckler’s Hard
A former ship-building village on the River Beaulieu in the New Forest. The setting is lovely, two rows of well-preserved red-brick workers’ cottages-separated by a lawn-lead down to the water’s edge where boats glide past. Attractions include a maritime (航海) museum telling the story of warships built for Nelson’s navy and other moments in seafaring history.
Costumed volunteers are on hand to answer questions and entertain children with, say, a game of coits or explain how families lived in the Shipwright’s Cottage. In summer hop on a boat for a cruise(漫游)up the river(extra charge).
Getting there
Take the M27, exit at junction 2 and follow the tourist signs towards nearby Beaulieu motor museum-from there Buckler’s Hard is signposted. The car park is an extra £6-£10. Train to Brockenhurst then taxi-or hire a bike and cycle the three miles through the New Forest.
Value for money?
Yes. The amount of time you take will likely depend on the weather. On a sunny day you could easily spend an afternoon for a reasonable £6.90 (adult), £4.70 (child 5-16) or £21 (family ticket for four).
Opening hours
10 a.m.-6 p.m. every day, except Christmas Day.

9 . The Biggest National Parks on Continents
North America
Covering nearly half of the world’s largest island, Northeast Greenland National Park is currently the globe’s single largest national park and biggest land-based protected area. It covers 972,000 square kilometers. The vast Greenland Ice Sheet makes up most of the park, but there’s also a long coastline that is home to musk oxen, polar bears and many other Arctic creatures.
Oceania
Covering 36,000 square kilometers, the Munga-Thirri-Simpson Desert National Park was set up in2021 to protect the beautiful desert landscapes of far northern South Australia. It includes one of the world’s largest dune (沙丘) fields. As well as more than 150 bird species, the park provides a habitat for many animals.
Asia
Founded in 2021, China’s Sanjiangyuan National Park is now the largest in Asia, covering 123,100square kilometers of snow-covered Qinghai-Tibet Plateau that provides the headwaters of the Yangtze, Yellow and Lantsang rivers. Rough and remote, the highlands harbor a range of rare, endangered animal species. The park also includes cultural sites.
Africa
Some of the world’s highest and biggest sand dunes are the centerpiece of western Namibia’s Namib-Naukluft National Park, Africa’s largest at 49,768 square kilometers. Easy to explore with your own vehicle, the main park road leads to the vibrant Sossusvlei dunes and photogenic Dead Vlei with its ghostly forest. Hot-air balloon flights offer a bird’s-eye view of the whole park. It is also known for plants and animals that have adapted to one of the Earth’s driest places.
