The ocean’s waves are immensely powerful. Harnessing that energy for grid-scale electricity production would be a major boon to the clean energy industry, but building durable, powerful, and cost-effective wave energy converters has proven difficult.

Now though, an influx of federal funding is helping many U.S. companies gear up to test their latest wave energy technologies, giving many in the industry hope that wave power will see massive growth over the next few decades.
South Sea pearls are the largest cultured-pearl variety, sometimes reaching over 20 millimeters in diameter. The Pinctada maxima oyster can take up to five years to produce a single South Sea pearl, whereas more common freshwater oysters can take as little as three months and create dozens of pearls. This long cultivation process makes South Sea pearls rarer — and more expensive. A single South Sea pearl can cost $1,500, and a necklace can reach over $200,000. So, how are these pearls grown? And what makes them so expensive?
Menaggio is about half way up the western side of Lake Como, an attractive and thriving town in the summer months and little more quiet in the winter! Accessible by car from Como at the south end of the lake, or Lugano in Switzerland, across the pass via Porlezza (340) above Menaggio but also by ferry from Bellagio and Varenna (where there is a train from Milan). The heart of the “old” town gathered around Piazza Garibaldi close to Menaggio’s harbour features mostly 19th century buildings in the Italian alpine style painted in muted tones.
Redwood National and State Parks are a string of protected forests, beaches and grasslands along Northern California’s coast. Jedediah Smith Redwoods State Park has trails through dense old-growth woods. Prairie Creek Redwoods State Park is home to Fern Canyon, with its high, plant-covered walls. Roosevelt elk frequent nearby Elk Prairie. Giant redwood clusters include Redwood National Park’s Lady Bird Johnson Grove.

The September 2022 issue features travel inspiration, starting with the island of Elba, just a short ferry ride from the coast of mainland Tuscany. Picture-perfect all year round, it’s certainly a destination we love. We also head to Molise for the Campobasso Mysteries Festival, take a detour to nearby Abruzzo, step off the beaten track to hilltop Casoli, and explore the exquisite city of Lecce.
A 3 day backpacking trip to climb Hermannsdalstinden Pinnacle, the highest mountain in the southern part of Lofoten.
Lofoten, island group, in the Norwegian Sea, northern Norway. Lying off the mainland entirely within the Arctic Circle, the group comprises the southern end of the Lofoten-Vesterålen archipelago and includes five main islands (Austvågøya, Gimsøya, Vestvågøya, Flakstadøya, and Moskenesøya) extending about 70 miles (110 km) from north to south. In addition, there are many small islands and skerries (rocky islets and reefs). The total length of the archipelago is about 110 miles (175 km).
A broad and deep fjord, the Vesterålsfjorden, lies between Lofoten and the mainland. The islands, composed of volcanic rocks (gneiss and granite), are the highly eroded tops of a partially submerged mountain range. The highest peak is Higravtinden (3,760 feet [1,146 metres]) on Austvågøya. North of the Arctic Circle, the islands are washed by the warm North Atlantic Current, which tempers their climate.
There are far too few workers in the U.S. to meet rising demand, a problem exacerbated by an aging population, low birthrates, and stifled immigration. It could become one of the biggest economic challenges of the next several decades.
