From sailboats to windmills, humans have been putting the kinetic energy of wind to work for thousands of years. The mechanics behind modern wind turbines are more sophisticated, but many of the basic principles remain. Utility-scale electricity generation installations use Horizontal Axis Wind Turbine...
Well 10 years (or even 5 years) will provide substantial clarity on the relative importance of human-caused and naturally varying climate change, and how rapidly humans can be expected to change the climate in the 21st century. The solutions to decarbonizing the global economy are more likely...
Big-bucks investors (including Google) are gambling tens of millions of dollars on a potentially game-changing new energy source—airborne wind turbines. The technology is revolutionary, but can it really turn a steady breeze into a paying
From the 1200s, windmills were used to pump excess water off the fertile soil, and windmills became an icon of the country. Today, however, most of the windmills have been replaced with electricity- and diesel-driven pumps. Reclaiming the Zuiderzee Storms and floods in 1916 provided the impe...
Dalian Haichang Discoveryland Theme Park is located in the Golden Pebble Beach National Tourism Resort. The park is built around a lake and it has large amusement facilities. Be sure not to miss the thrilling “Crazy Cobra” roller coaster. You can also enjoy wonderful live shows, parades of...
The Noach, built in 1857. View original image At the moment, there are at least two sailing ships in development that are being built from scratch: theCeibaand theEcoClipper500. The first ship is being constructed in Costa Rica by a company namedSailcargo. She is built from wood and insp...
Holland is already shutting down those recently built coal fired power plant and is investing heavily in alternative energy sources and reduction of emissions from traffic, industry and agriculture. Even natural gas as a source of energy will be abandoned soon. Wind farms are being built on land...
When theEssexdeparted from Nantucket for the last time in the summer of 1819, Nantucket had a population of about 7,000, most of whom lived on a gradually rising hill crowded with houses and punctuated by windmills and church towers. Along the waterfront, four solid-fill wharves extended more...
They made windmills that could steal some of the wind’s joules as it went by and convert them into mechanical energy to grind food. They built sailboats that would convert wind joules into kinetic boat energy they could control. Water absorbs the sun’s radiation joules and turns them into...
But something else which is also concerning is the condition the ocean was in, even prior to the spill. We live in a finite world. Our continued mistreatment of the ocean, the reduced fish population, and the disappearance of large fish in the last 50 years are all serious concerns. ...
