The House She Built a Source of Conflict

-
There was a time when everything seemed to be going right for Amara . She was a beautiful woman, not only in appearance but in the way she carried herself. She grew up in a loving home, surrounded by parents who worked hard and believed that their children should never lack opportunities. Her father was a respected man who worked tirelessly to provide for the family, while her mother was equally hardworking. They raised their daughters with discipline, kindness, and the belief that education and hard work were the keys to a good life. Amara was the elder daughter. Her younger sister, Nadia , was also intelligent and ambitious. The two sisters grew up watching their parents work together, and they learned an important lesson from them: nothing worthwhile comes without sacrifice. As the years passed, both sisters became successful in their own ways. Amara worked hard, saved her money, and eventually achieved something she had dreamed about since she was young. She bought a beauti...

Nuclear scientists hail US fusion breakthrough

 Nuclear scientists using lasers the size of three football fields say they generated a huge amount of energy from fusion

Nuclear scientists using lasers the size of three football fields say they generated a huge amount of energy from fusion.

Nuclear scientists using lasers the size of three football fields said Tuesday they had generated a huge amount of energy from fusion, possibly offering hope for the development of a new clean energy source.

Experts focused their giant array of almost 200 laser beams onto a tiny spot to create a mega blast of energy—eight times more than they had ever done in the past.

Although the energy only lasted for a very short time—just 100 trillionths of a second—it took scientists closer to the holy grail of fusion ignition, the moment when they are creating more energy than they are using.

"This result is a historic advance for inertial confinement fusion research," said Kim Budil, the director of Lawrence Livermore National Laboratory, which operates the National Ignition Facility in California, where the experiment took place this month.

Nuclear fusion is considered by some scientists to be a potential energy of the future, particularly because it produces little waste and no greenhouse gases.

It differs from fission, a technique currently used in nuclear power plants, where the bonds of heavy atomic nuclei are broken to release energy.

In the fusion process, two light atomic nuclei are "married" to create a heavy one.

In this experiment scientists used two isotopes of hydrogen, giving rise to helium.

This is the process that is at work in stars, including our Sun.

"The NIF teams have done an extraordinary job," said Professor Steven Rose, co-director of the center for research in this field at Imperial College London.

"This is the most significant advance in inertial fusion since its beginning in 1972."

But, warned Jeremy Chittenden, co-director of the same center in London, making this a useable source of energy is not going to be easy.

"Turning this concept into a renewable source of electrical power will probably be a long process and will involve overcoming significant technical challenges," he said.

This New Ultralight Aircraft May Be World’s Fastest Single-Engine Business Jet

  The speedy LAR-01's automotive interior adds comfort and luxury. Plus: The wings detach, so the jet can be stored in a home garage. By  MICHAEL VERDON           Courtesy Flaris The  Flaris  LAR-01 has a number of striking stats, including being a ton lighter (literally) than its competitors, along with an unusually short-field landing capability, and detachable wings. But its most impressive number is the 250-knot true air speed, which its designers say makes it the world’s fastest business jet among single-engine very light jets and turboprop aircraft. Flaris says recent tests “confirmed the assumptions made previously” about the effectiveness of multiple systems, including its Garmin G600 avionics and Flaris Flight Assistance System flight computer, as well as the landing gear and emergency parachute system. But it also claims more impressive stats like the 250-knot TSA at 10,000 feet. Its 6,000-feet-per-minute climb rate, adds the compan...

Fighting Drug addiction

-
 Here's the story: We sat down with a man who had a harrowing journey with addiction. He began by telling us about his early days in tertiary education, where he would occasionally smoke dagga with friends. However, his focus remained on his studies, and he worked hard to graduate and secure a qualification. After landing a job, he started building a life for himself. He got married, bought a property, and even splurged on a car. Life was good, and he felt like he was on top of the world. But one fateful night, while out with friends, he was introduced to heavier narcotics. At first, the experience was exhilarating. He described it as an elevation from the mild high of dagga to a level 5 high, where he felt invincible and euphoric. The effects would last for days, allowing him to party from Friday to Sunday without sleep. The problem, however, began to manifest on Mondays and Tuesdays every week, when the withdrawal symptoms would kick in, and he'd struggle to function at work....

Ultra-Widebody Volkswagen Bus "Volkswide" Looks Like a Porsche Racing Van

  Home   >   News   >   Renderings It's easy to understand why a muscle car or a Ferrari is cool - the big engine and cool body. But car culture is also influenced by television, rarity, or simply a generation growing up with a particular vehicle. The Volkswagen Bus is a perfect example of this because it's slow, not sporty-looking, yet it can cost a lot of money.  16 photos The Bus is perhaps one of the least understood collectibles, right up there with bubble cars. You see them grabbing huge money at auctions, making it difficult to visualize why somebody wouldn't rather have a Ferrari or some 1960s Mustang. Comedian Gabriel Iglesias is known as the VW Bus King, as his collection of Vdubs is reportedly worth in excess of $3 million. The Hoonigan crew recently did a feature video, but we still had trouble picturing the value of these vehicles. Fortunately, there's a set of renderings that takes the visuals of the Microbus to the level where everybody...
