Technology harvests energy from railroad train vibrations

Engineers have won a national award for an innovative energy harvester that has the potential to save millions of dollars in energy costs for railroads while reducing carbon dioxide emissions.

 

The team's work, "Mechanical Motion Rectifier (MMR) based Railroad Energy Harvester," was awarded "Best Application of Energy Harvesting" at the Energy Harvesting and Storage USA 2012 conference, held in Washington, DC on November 7-8, 2012.
The Stony Brook team, led by Professor Lei Zuo and two graduate students Teng Lin and John Wang from the Department of Mechanical Engineering and Advanced Energy Research and Technology Center, developed a new type of energy harvester that converts the irregular, oscillatory motion of train-induced rail track vibrations into regular, unidirectional motion, in the same way that an electric voltage rectifier converts AC voltage into DC.

 

Professor Zuo estimates that the invention could save more than $10 million in trackside power supply costs for railroads in New York State alone, along with a reduction of 3000 tons per year of CO2 and a half million dollars of electricity savings.

Almost Being There: Why the Future of Space Exploration Is Not What You Think

Almost Being There: Why the Future of Space Exploration Is Not What You Think | Everettce | Scoop.it

Mocup is a tiny, adorable remote-controlled robot built from a Lego Mindstorms set with an off-the-shelf Beagleboard computer for a brain and a webcam for an eye. The machine is not fundamentally different from many other RC robots — except for the fact that its controller operates it from space.

 

The cat-sized robot can do little more than move around, avoid obstacles, and transmit video. It’s mostly a testbed for communications to help humans in orbit and robots on the surface of a planet work seamlessly together. On Oct. 23, astronaut Sunita Williams sent commands from the International Space Station to Mocup – which stands for the Meteron Operations and Communications Prototype – telling it to travel around an obstacle course in Germany. The test may seem mundane but Mocup represents the first step in dramatically redefining how we discover and investigate the universe.

Rapture of the nerds: will the Singularity turn us into gods or end the human race?

Rapture of the nerds: will the Singularity turn us into gods or end the human race? | Everettce | Scoop.it

Hundreds of the world’s brightest minds — engineers from Google and IBM, hedge funds quants, and Defense Department contractors building artificial intelligence — were gathered in rapt attention inside the auditorium of the San Francisco Masonic Temple atop Nob Hill. It was the first day of the seventh annual Singularity Summit, and Julia Galef, the President of the Center for Applied Rationality, was speaking onstage. On the screen behind her, Galef projected a giant image from the film Blade Runner: the replicant Roy, naked, his face stained with blood, cradling a white dove in his arms.

At this point in the movie, Roy is reaching the end of his short, pre-programmed life, “The poignancy of his death scene comes from the contrast between that bitter truth and the fact that he still feels his life has meaning, and for lack of a better word, he has a soul,” said Galef. “To me this is the situation we as humans have found ourselves in over the last century. Turns out we are survival machines created by ancient replicators, DNA, to produce as many copies of them as possible. This is the bitter pill that science has offered us in response to our questions about where we came from and what it all means.”

No magic: Real-world levitation to inspire better pharmaceuticals

No magic: Real-world levitation to inspire better pharmaceuticals | Everettce | Scoop.it

It’s not a magic trick and it’s not sleight of hand – scientists really are using levitation to improve the drug development process, eventually yielding more effective pharmaceuticals with fewer side effects.

 

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have discovered a way to use sound waves to levitate individual droplets of solutions containing different pharmaceuticals. While the connection between levitation and drug development may not be immediately apparent, a special relationship emerges at the molecular level.

 

At the molecular level, pharmaceutical structures fall into one of two categories: amorphous or crystalline. Amorphous drugs typically are more efficiently taken up by the body than their crystalline cousins; this is because amorphous drugs are both more highly soluble and have a higher bioavailability, suggesting that a lower dose can produce the desired effect.

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over

New study: There is enough wind potential on Earth's surface to power human civilization 100 times over | Everettce | Scoop.it

At the moment, wind power supplies about 4.1 percent of electric power in the United States. Still a bit player. Yet there’s a whole lot of untapped wind left in the world. Wind whipping through the Great Plains. Wind gusting off the shores. Wind circulating high up in the sky. So what would happen if we tried to harvest all of that wind?

 

We’d have enough energy to power the world. At least in theory. A new study published this week in Nature Climate Change finds that there’s enough wind potential both on the Earth’s surface and up in the atmosphere to power human civilization 100 times over. Right now, humans use about 18 terawatts of power worldwide. And, technically, the study found, we could extract about 400 terawatts of wind power from the Earth’s surface and 1,800 terawatts of power from the upper atmosphere.

 

Even the most optimistic near-term projections for wind power, however, tend to be more restrained. In 2008, the U.S. Department of Energy released a comprehensive report estimating that wind power could provide, at most, 20 percent of U.S. electricity by 2030. And for that to happen, the cost of wind power would have to keep plunging, the number of turbines built would have to steadily increase by about 14 percent each year, and utilities would have to build new transmission lines to accommodate the extra energy.

Christina's curator insight, January 9, 2013 10:15 PM

My thoughts:

I have noticed that i am stressed often. This is really no fun, i hate being stressed. This article informed me of some ways i can cope with it. I need to find someone i can talk to about myself. Keeping thoughts in will just cause more stress that i dont need. Also eating healthier will reduce stress. Taking a breather and maybe even doing yoga will help me deal with my stress. Stress is very bad for you it can actually affect your health and being this young i shouldnt even need to stress about anything.

Stress is a feeling of pressure or tension on a material object.
