3 . Not unlike the wings of airplanes, the blades (叶片) of wind turbines (涡轮机) need to be kept ice-free in order to function properly. Scientists have now developed an inexpensive method of using drones (无人机) to apply an eco-friendly anti-icing coating (涂层) to those blades.
If too much ice builds up on wind turbine blades, they will turn more slowly, producing less energy. What’s more, if an equal amount of ice isn’t present on all three blades, the turbine’s balance may be thrown off, leading to increased wear and possibly even disastrous failure.
There are anti-icing heating systems that can be built into the blades, but these may be beyond the financial means of many wind farm (风电场) operators. The same can be said for using helicopters to apply ice-prevention chemicals.
Seeking a more economical but still effective alternative, scientists from two branches of Germany’s Fraunhofer research group recently started looking to drones. The research project is known as “TURBO: Temporary coating by means of drones — Icing protection of wind turbines as a case study”.
In the current version of the resulting system, a hexacopter drone is equipped with a small pump that delivers anti-icing liquid. The liquid is sprayed (喷洒) at high pressure — which is just 0. 3 mm wide — producing tiny droplets with a diameter of 100 micrometers.
Using this setup, the drone has successfully been used to apply coatings of the droplets onto the edges of wind turbine blades, even at wind speeds of up to 35 km/h (22 mph). Once solidified (固化/凝固), those coatings prevent ice formation for several weeks before a fresh coating is applied.
The scientists are now seeking industry partners to help commercialize (商业化) the TURBO technology. It could also find use in the maintenance (维护) of power lines, the upper levels of tall buildings, or other things that are difficult to reach by conventional means.

9 . You are what you think. Whatever you are doing right now is determined by your thinking. All your emotions and desires are influenced by your thinking. The problem is that when you are not aware of your thinking, you have no chance of correcting it if it is poor. When thinking is subconscious, you are in no position to see any problems in it. And, if you don’t see any problems in it, you won’t be motivated to change it. What’s worse, few people realize the powerful role that thinking plays in their lives, so they don’t gain significant command of it. As a result, most people are in many ways victims of their thinking.
Consider your success as a student. The single most significant variable in determining your success as a student is the quality of your thinking. Your instructors will play a role in your learning, but even the best teachers cannot get into your head and learn for you. If you lack the intellectual skills necessary for thinking well through course content, you will not be successful in school.
Here is the key question we are putting to you in this book. If the quality of a person’s thinking is the single most significant determinant of both happiness and success, why not take the time to learn from the best thinkers?
This book will inform you of the tools that the best thinkers use and will illustrate the activities and practice you can use to begin to emulate them, and take control of your destiny as a thinker. Each chapter focuses on a different aspect of these thinking aids, helping you discover the power of your own mind and of your potential to think systematically about your thinking.
This book, as a whole, introduces you to the tools of mind that will help you reason well through various challenges you face. If you take these ideas seriously and practice using them, you can improve the quality of your thinking and ultimately, the quality of your life.

10 . Some beaches are perfect for relaxing, while others offer activities like hiking and water sports. Visit these beautiful beaches for an unforgettable vacation.
Cannon Beach
If your perfect beach vacation spot features postcard-worthy scenery and peace, look no further than Cannon Beach. In this Pacific Northwest town, you can even build a fire on the beach to relax beside while watching the sun set. When you need a break from the beach, grab a bike and head downtown to explore its art galleries, shops and restaurants.
Horseshoe Bay Beach
For a one-of-a-kind beach experience, head to Horseshoe Bay Beach on Bermuda’s South Shore. Known for its pink sand, this beach is a popular destination for families looking to play in the calm blue-green waters and build blush-colored sandcastles. Adventure seekers can also take part in the self-guided island bicycle tour or engage in exciting water sports.
Mohegan Bluffs
This beach is famous for its natural beauty. Upon arrival, pause to admire your surroundings and learn about its ties to the native people, their ancient traditions, and connection to the land, adding depth to your beach experience. Then, take the 141 steps down to the sand to sunbathe. After that, climb back up to visit the Southeast Light for an up-close view of its 18th-century lighthouse.
South Beach
This tropical district on Florida’s Atlantic Coast is world-renowned for its powdery white sand. Although technically part of the Miami Beach area, South Beach stands out due to its Art Deco architecture seen in everything from the beachfront lifeguard towers to the high-rise buildings along the famed Ocean Drive.
