Structural supercapacitors could make batteries and power cords obsolete

 

 

Imagine using a mobile phone powered entirely by its casing, or an electric car that runs off power stored in its chassis. Researchers at Vanderbilt University have created a structural supercapacitor that could, they believe, bring this closer to reality, making batteries and power cords obsolete. The structural supercapacitor could make it possible to store energy directly in structural materials, allowing them to deliver power long-term while surviving the real-life mechanical stresses they're bound to experience.

 

The team's new supercapacitor looks like a thin grey wafer, and is made of silicon electrodes that have been chemically treated to have inner surfaces containing nanoscale pores. Instead of storing energy in chemical reactions, like batteries, the supercapictor stores power by assembling electrically-charged ions on the surface of the porous material. In a recent test, the supercapacitor was able to store and release power without a hitch, the team reported, even when it was subjected to vibrational accelerations exceeding 80 g and stresses of up to 44 psi.

 

“These devices demonstrate – for the first time as far as we can tell – that it is possible to create materials that can store and discharge significant amounts of electricity while they are subject to realistic static loads and dynamic forces, such as vibrations or impacts,” said Cary Pint, Assistant Professor of Mechanical Engineering at Vanderbilt University.

 

Being able to create hardy structural materials that can efficiently store and deliver energy opens up many exciting possibilities. For instance, instead of being inert, the walls of a home or a building could store and deliver power to all the home's lights and appliances.

 

"The majority of building materials that we use in these systems have absolutely no function than to just maintain mechanical integrity," Pint tells Gizmag. "What if we could take the tons of materials used in homes and convert them to energy storage systems that were not more expensive, could perform the same mechanical function as building materials, but could have decades worth of energy storage capability built in?".

 

"For a home or stationary powered system, this technology is the seed to putting solar panels on the roof and enabling power delivery around the clock without the need for a grid, even when the sun isn't shining," he adds.

There is no animation in this image. It's your brain.

 

 

 

 

Thanks for the seizure, bro.  I stared at it for like 30 seconds, trying to get it to stop moving.  I failed.

Astronomers Spot Eye of Sauron

 

A new advanced imaging tool has captured a deep-space shot that looks uncannily similar to the Eye of Sauron from The Lord of the Rings. But have no fear, the all-seeing eye is just the star HR 4796A, and its fiery ring is merely dust and debris, Slate reports. About 270 light-years away from Earth, the star is one of the first images captured by SPHERE, or the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument, in Chile.

replace 90% of those cars with mororcycles, and increase the volume by 184%, and you have every street in Hanoi.  

 

 

increase the volume by 457%, and stopp the picture from moving, and you have every street in Lagos.

According to a new paper posted on Arxiv, the Big Bang may not have been what we think it is. In fact, there may have been no Big Bang at all--our universe may have come from an entirely different source.

 

...

 

This new explanation suggests that the universe might actually be the result of the collapse of a four-dimensional star--a crazy black hole the likes of which we can't even imagine. Some explanation:

 

In that model, our three-dimensional (3D) Universe is a membrane, or brane, that floats through a 'bulk universe' that has four spatial dimensions. [The] team realized that if the bulk universe contained its own four-dimensional (4D) stars, some of them could collapse, forming 4D black holes in the same way that massive stars in our Universe do: they explode as supernovae, violently ejecting their outer layers, while their inner layers collapse into a black hole.

 

The idea is that black holes as we know them--3-D black holes, in our known universe--have as a boundary a 2-D membrane, which is called an "event horizon." But in the event of a 4-D black hole, the event horizon would be a 3-D event horizon--and according to models run by the team, a collapse of a 4-D star would spew material into the 3-D event horizon, slowly expanding over time. That event horizon could be, well, our universe.

(CNN) -- At 14 feet long and 2,300 pounds, it's only fitting that Katharine is heading for the land where everything is bigger.

This massive great white shark was most recently spotted 100 miles off the Florida coast in the Gulf of Mexico, headed toward Texas. And as of June 5, another great white, Betsy, was about 140 miles west of Sarasota, Florida.

In August, researchers from the nonprofit group Ocearch tagged Katharine off Massachusetts' Cape Cod, along with the 14-foot long, 2,300-pound shark Betsy. Every time the sharks surface, their tags send signals to a satellite that can then pinpoint their locations, which can be viewed in near real time on the Ocearch website. So far, each of these sharks has traveled over 1,400 miles.

It is estimated that Katharine will be past the mouth of the Mississippi River in a week and will enter the waters off Texas not long afterward if she keeps to her current course. A researcher says the sharks' paths are surprising for this time of year.

"Every track is giving us new information and going contrary to all the assumptions that we were going on," Dr. Robert Heuter, director of Mote Marine Laboratory's center for shark research, told the Houston Chronicle. "Having (sharks) in the Gulf is something we thought happened in the wintertime."

These huge sharks' irregular behavior comes on the heels of the catch of a rare goblin shark in Florida in May and the closing of an Alabama beach because of a "swarm" of sharks this month. Fortunately for the Lone Star State, scientists will be able to track Katharine as she approaches and keep tabs on her and Betsy for a long time to come. According to Heuter, "These tags can last as many as five years. It gives us a completely different perspective from the older tags."
