Kymatica (2009)
When you think the end is near, the apocalypse, Armageddon, and when you think we as a species are doomed, it is not they, it is you that brought this about, and for a very good reason. You are evolving. Stop blaming everybody and everything else. Quit panicking about global tyranny and natural disaster and pay attention, because the world is telling you something; it’s tell you exactly what is wrong with you and how to fix it.

Italian scientist claims he has achieved 'cold fusion' - the only problem is that most physicists think it is impossible
- Andrea Rossi says he can fuse nickel and hydrogen at room temperature creating almost unlimited energy
- Many scientists simply claim it defies the very laws of physics and cannot be true
True or false? Andrea Rossi, pictured, says he has built a machine achieving 'cold fusion' but scientists question if it is possible
An Italian physicist claims he has managed to achieve 'cold fusion' - a procedure that could solve the world's energy crisis by creating huge amounts of safe nuclear energy without dangerous radiation.
Andrea Rossi says his new machine fuses nickel and hydrogen at room temperature creating almost unlimited energy.
But there is one problem - many scientists claim it defies the very laws of physics. Several high-profile demonstrations of 'cold fusion' have been proven to be hoaxes in the past - and no one can adequately explain how or why it might work.
The United States Department of Energy the U.S. Patent Office say the process is impossible because physics rules out the possibility of room-temperature nuclear fusion.
But Rossi's E-Cat machine can allegedly do it, and he says he proved it worked during tests at the University of Bologna last month.
'With low energy, it's possible to give a heater a certain amount of energy and to get from the same heater a superior amount of energy,' he said.
'The heat is initiated by electrical resistance. The reactors then produce another 479kWh of energy for another three to four hours without needing that initial electrical input -- the low-level nuclear reaction continues on its own.
The World in 2100: Ten Billion People, No Oil and Not Enough Food
With global population now at seven billion, it may be time to start planning for what the world will look like in the coming years.
Though most of us won't be around to see it, the United Nations has projected that our incredible population growth will level off at around 10 billion people by the year 2100.
Already, at seven billion, we are experiencing severe poverty, hunger, a shortage of resources, increased urbanization and climate change issues.
Will we be doomed by 2100, or can we make it work? Since we've only got one planet (so far), let's hope for the latter.

Scientists build the world's first anti-laser
Traditional lasers rely on gain mediums to produce beams of coherent light
Physicists have built the world's first device that can cancel out a laser beam - a so-called anti-laser.
The device, created by a team from Yale University, is capable of absorbing an incoming laser beam entirely.But this is not intended as a defence against high-power laser weapons, the researchers said.
Instead they think it could be used in next-generation supercomputers which will be built with components that use light rather than electrons.
Professor Douglas Stone and colleagues at Yale University had initially been developing a theory to explain which materials could be used as the basis of lasers.
Strange lasers Recent advances in laser design have resulted in a number of unusual devices that do not fit the traditional concept of a laser, Professor Stone explained.
"So we were working on a theory that could predict what could be used to form a laser," he said.
That theory also predicted that instead of amplifying light into coherent pulses, as a laser does, it should be possible to create a device that absorbs laser light hitting it, said Professor Stone - an anti-laser.
They have now succeeded in building one.
What is a laser?
- A laser is a device that can produce a beam of coherent light
- The beam is produced using a quantum effect, whereby electrons can be made to emit light
- That is achieved by stimulating electrons inside a gain medium, typically using an electric current
- Resonators are used to amplify the light produced to form the intense beam
Their device focuses two lasers beams of a specific frequency into a specially designed optical cavity made from silicon, which traps the incoming beams of light and forces them to bounce around until all their energy is dissipated.
In a paper published in the journal Science they demonstrated that the anti-laser could adsorb 99.4 per cent of incoming light, for a specific wavelength. Light speed Altering the wavelength of the incoming light means that the anti-laser can effectively be turned on and off - and that could be used in optical switches, Professor Stone told BBC News.
The anti-laser could turn out to be more useful in computing than weapon defence
The anti-laser's big advantage is that it is built using silicon, which is already widely used in computing.
It would not, however, be much use as a laser shield, according to Professor Stone.
"The energy gets dissipated as heat. So if someone sets a laser on you with enough power to fry you, the anti-laser won't stop you from frying," he said.

Green Float: The futuristic concept that sees humans live in
giant skyscrapers on floating water lilies in the middle of the Pacific
giant skyscrapers on floating water lilies in the middle of the Pacific
Humans in the future could live in mini floating cities that drift across the Pacific as if on giant water lilies.
The startling new concept has been dreamed up by Japanese technology firm Shimizu and is designed to be a way of harnessing green technologies and creating carbon-neutral cities.
The Green Float concept involves a number of cells, each one kilometre wide, that house between 10,000 and 50,000 people.
The majority of people on the cells would live in huge towers 1km high surrounded
by lush green fields
by lush green fields
Each individual cell would be free to float on the Pacific Ocean near the equator but could also be joined together with other cells to form larger towns and even cities.
A group or modules, a collection of cells, would become a country in its own right.
Most people in this brave new world would live in a 1 kilometre-high ‘City in the Sky’ at the centre of each cell. More people would live in residential areas around the edge of the cell.
The central towers would be surrounded by grassland and forests and be self-sufficient in terms of food, while livestock and other farming would take place in 'plains' also surrounding the tower - all built on a lattice of 7,000-tonne honeycomb pontoons.
The towers would be built from super-light alloys with the metal deriving from magnesium in seawater.
The imaginative plan is designed to create a future carbon-neutral society and the Shimizu developers claim that living on cells in this way would cut carbon emissions by 40 per cent.

The floating cells, each with a City in the Sky structure at its centre,
can join together to form larger modules
The City in the Sky skscrapers are designed to be carbon negative with extensive environmental technologies and recycling facilities built in
The cells would create zero waste and recycle every product and covert waste into energy using new green technologies. Islands of waste would drift around the ocean and could be ‘harvested’ to provide energy
The location of the islands is key to their success too, the designers claim.
Each group of cells would be near the equator where the climate is at its most stable and a range of technologies would be used to protect the floating cities from tidal waves and extreme weather.
To protect the inhabitants from large waves, strong elastic membranes would be attached to the lagoons around the outer edge of the cells, with the shallows above the membranes standing 30 feet above sea level.
Shimizu scientists calculate that the water pressure difference between the lagoons and the ocean would limit the movement of the membranes and buffer the force of the open sea waves.
Seawalls as high as 100 feet could also be constructed. And tsunamis in the open sea are far less dangerous than those that hit coastal areas, the designers say.
A country consisting of one million people would be formed after
modules joined together one by one
Lightning rods would be fitted around the circumference of the towers and mesh lightning conductors will be placed on the exterior walls to protect against lightning strikes.
Shimizu wants to develop the first cells by 2025 and is concentrating on developing the technologies to make it happen. The concept was displayed at a recent Japanese university conference.
This is the not the first outlandish idea that Shimizu has come up with. The firm also proposes encircling the moon in a belt of solar collectors that would collect solar energy and transmit it to Earth.

Reverse Combustion: Can CO2 Be Turned Back into Fuel?
Various efforts are underway to find a cheap, efficient and scalable way to recycle the greenhouse gas carbon dioxide back into the hydrocarbons that fuel civilization

But by 2003, Chao's successor in the Princeton lab of chemist Andrew Bocarsly was deeply interested in finding a solution to the growing problem of the CO2 pollution causing global climate change. Graduate student Emily Barton picked up where he left off and, using an electrochemical cell that employs a semiconducting material used in photovoltaic solar cells for one of its electrodes, succeeded in tapping sunlight to transform CO2 into the basic fuel.
"The dominant thinking 10 years ago was that we should bury the CO2. But if you could efficiently convert it into something that we wouldn't have to spend all that money and energy to put into the ground, sort of recycle it, that would be better," Bocarsly says. "We take CO2, water, sunlight and an appropriate catalyst and generate an alcoholic fuel."
He adds: "We didn't have some brilliant insight here. We had some luck." Luck that venture capitalists are now trying to turn into cash flow via a start-up known as Liquid Light.
Turning CO2 into fuels is exactly what photosynthetic organisms have been doing for billions of years, although their fuels tend to be foods, like sugars. Now humans are trying to store the energy in sunlight by making a liquid fuel from CO2 and hydrogen—a prospect that could recycle CO2 emissions and slow down the rapid buildup of such greenhouse gases in the atmosphere. "You take electricity and combine CO2 with hydrogen to make gasoline," explained Arun Majumdar, director of the Advanced Research Projects Agency–Energy (ARPA–e) that is pursuing such technology, at a conference in March. "This is like killing four birds with one stone"—namely, energy security, climate change, the federal deficit and, potentially, unemployment.
"When these new technologies get commercialized, those jobs always end up in the U.S.," argues chemical engineer Alan Weimer of the University of Colorado at Boulder, who is working on such solar-fuel generators. Adds chemist Michael Berman of the U.S. Air Force Office of Scientific Research, which is funding research into the possibilities of solar fuels, including Bocarsly's work: "The country, and the Air Force, need secure and sustainable sources of energy…. Since the sun provides enough energy for our needs, our goal is to make a fuel using CO2 and sunlight—and maybe water—as feedstocks to produce the chemical fuel that can store the sun's energy in a form that we can use where and when we need."
Editor's Note (9/24/10): This broadcast stated incorrectly that it takes 18 kilowatts to separate hydrogen and oxygen in one gallon of water. The correct term is kilowatt hours, a unit of energy. It also incorrectly stated hydrogen and oxygen molecules, rather than atoms, comprise water.

New Level of Cosmic Consciousness.
Truth and Reality.
Truth and Reality.
The concept of higher consciousness rests on the belief that the average, ordinary human being is only partially conscious due to the character of the untrained mind and the influence of 'lower' impulses and preoccupations. As a result, most humans are considered to be asleep (to reality) even as they go about their daily business

The National Ignition Facility: Ushering in a New Age for Science
Scientists have been working to achieve self-sustaining nuclear fusion and energy gain in the laboratory for more than half a century. When the National Ignition Facility (NIF) begins ignition experiments at Lawrence Livermore National Laboratory (LLNL) in 2010, that long-sought goal will be much closer to realization.“Every great advance in science has issued from a new audacity of imagination.”
—John Dewey
NIF's 192 giant lasers, housed in a ten-story building the size of three football fields, will deliver at least 60 times more energy than any previous laser system. When all of its beams are fully operational, NIF will focus nearly two million joules of ultraviolet laser energy on a tiny target in the center of its target chamber – creating conditions similar to those that exist only in the cores of stars and giant planets and inside a nuclear weapon. The resulting fusion reaction will release many times more energy than the laser energy required to initiate the reaction.
Experiments conducted on NIF will make significant contributions to national and global security, could lead to practical fusion energy, and will help the nation maintain its leadership in basic science and technology. The project is a national collaboration among government, industry and academia and many industrial partners throughout the nation.
Programs in the NIF & Photon Science Directorate draw extensively on expertise from across LLNL, including the Physical and Life Sciences, Engineering, Computation and Weapons and Complex Integration directorates. This goal is a scientific Grand Challenge that only a national laboratory such as Lawrence Livermore can accomplish.

An international team of scientists from Russia and the United States, including two Department of Energy national laboratories and two universities, has discovered the newest superheavy element, element 117.
The team included scientists from the Joint Institute of Nuclear Research (Dubna, Russia), the Research Institute for Advanced Reactors (Dimitrovgrad), Lawrence Livermore National Laboratory, Oak Ridge National Laboratory, Vanderbilt University, and the University of Nevada, Las Vegas.
“The discovery of element 117 is the culmination of a decade-long journey to expand the periodic table and write the next chapter in heavy element research,” said Academician Yuri Oganessian, scientific leader of the Flerov Laboratory of Nuclear Reactions at JINR and spokesperson for the collaboration.
The team established the existence of element 117 from decay patterns observed following the bombardment of a radioactive berkelium target with calcium ions at the JINR U400 cyclotron in Dubna. The experiment depended on the availability of special detection facilities and dedicated accelerator time at Dubna, unique isotope production and separation facilities at Oak Ridge, and distinctive nuclear data analysis capabilities at Livermore.
“This is a significant breakthrough for science,” LLNL director George Miller said. “The discovery of a new element provides new insight into the makeup of the universe and is a testimony to the strength of science and technology at the partner institutions.”
“This collaboration and the discovery of element 117 demonstrates the fundamental importance of scientists from different nations and institutions working together to address complex scientific challenges,” ORNL Director Thom Mason added.
The two-year experimental campaign began at the High Flux Isotope Reactor in Oak Ridge with a 250-day irradiation to produce 22 mg of berkelium. This was followed by 90 days of processing at Oak Ridge to separate and purify the berkelium, target preparation at Dimitrovgrad, 150 days of bombardment at one of the world’s most powerful heavy ion accelerators at Dubna, data analysis at Livermore and Dubna, and assessment and review of the results by the team. The entire process was driven by the 320-day half-life of the berkelium target material.

The island of stability is a term in nuclear physics that refers to the possible existence of a region beyond the current periodic table where new superheavy elements with special numbers of neutrons and protons would exhibit increased stability. Such an island would extend the periodic table to even heavier elements and support longer isotopic lifetimes to enable chemistry experiments.
Element 117 was the only missing element in row seven of the periodic table. On course to the island of stability, researchers initially skipped element 117 due to the difficulty in obtaining the berkelium target material. The observed decay patterns in the new isotopes from this experiment, as close as researchers have ever approached the island of stability, continue a general trend of increasing stability for superheavy elements with increasing numbers of neutrons in the nucleus. This provides strong evidence for the existence of the island of stability.
“It fills in the gap and gets us incrementally closer than element 116 — on the edge of the island of stability,” said Ken Moody, one of the LLNL collaborators and a long term veteran of superheavy element research. “The experiments are getting harder, but then I thought we were done 20 years ago.”
This discovery brings the total to six new elements discovered by the Dubna-Livermore team (113, 114, 115, 116, 117, and 118, the heaviest element to date). This is the second new element discovery for Oak Ridge (61 and 117). In addition, Oak Ridge isotopes have contributed to the discovery of a total of seven new elements.
Since 1940, 26 new elements beyond uranium have been added to the periodic table.
“These new elements expand our understanding of the universe and provide important tests of nuclear theories,” said Vanderbilt University Professor of physics Joe Hamilton. “The existence of the island of stability, a pure theoretical notion in the 1960s, offers the possibility of further expansion of the periodic table with accompanying scientific breakthroughs in the physics and chemistry of the heaviest elements.”

Heat-Channeling Carbon Nanotubes Produce
100 Times More Energy than Li-ion Batteries
100 Times More Energy than Li-ion Batteries
"Thermopower waves" could be a brand-new way to produce electricity
By Jeremy Hsu
Nanotube Heat Wave And it burns, burns, burns ... MIT
The new experiments involved nanotubes, or submicroscopic structures just a few billionths of a meter in diameter, that can conduct both electricity and heat. Engineers coated the nanotubes with reactive fuel that produces heat by decomposing, and then ignited it with laser beams or high-voltage sparks.
That set off a fast-moving heat wave that traveled through the nanotube's hollow cylinder 10,000 times faster than in the reactive fuel itself, and reached a temperature of 4,940 degrees F (3,000 Kelvin). The fast-moving heat also pushed electrons along the tube and created a noticeable electrical current.
Such combustion waves were studied mathematically for a century, according to Michael Strano, a chemical engineer at MIT. Strano first predicted that a nanotube or nanowire could channel the heat pulse and create electrical current, but now his group has realized that prediction.
Some semiconductor materials can also produce an electric current when heated, but the carbon nanotube experiments defy predictions by thermoelectric calculations. Strano noted that the heat wave seemed to carry along electrons or other electrical charge carriers, not unlike how an ocean wave can pick up debris.
The possibility of creating substantial energy on such a tiny scale could lead to new ultra-small electronic devices the size of rice grains, whether for implantable medical chips or other tiny sensor applications.
Strano's MIT group plans to continue improving the efficiency and cut back on wasted energy given off as heat and light. Strano also suggested that a different reactive fuel coating for the nanotubes might produce alternating current -- an intriguing contrast to current energy-storage systems that all produce direct current.

MU Researchers Create Smaller and More Efficient Nuclear Battery
Mizzou scientist develops a powerful nuclear battery that uses a liquid semiconductor
COLUMBIA, Mo. – Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with high energy density,” said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope battery can provide power density that is six orders of magnitude higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, currently the size and thickness of a penny, intended to power various micro/nanoelectromechanical systems (M/NEMS). Although nuclear batteries can pose concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said. “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His innovation is not only in the battery’s size, but also in its semiconductor. Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The critical part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor,” Kwon said. “By using a liquid semiconductor, we believe we can minimize that problem.”
Kwon has been collaborating with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, and is working to build and test the battery at the facility. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that the battery could be thinner than the thickness of human hair. They’ve also applied for a provisional patent.
Kwon’s research has been published in the Journal of Applied Physics Letters and Journal of Radioanalytical and Nuclear Chemistry. In addition, last June, he received an “outstanding paper” award for his research on nuclear batteries at the IEEE International Conference on Solid-State Sensors, Actuators and Microsystems in Denver (Transducers 2009).
