Beaverton boy lauded for solar cell invention

BEAVERTON, Ore. – A new invention could revolutionize solar energy – and it was made by a 12-year-old in Beaverton.

Despite his age, William Yuan has already studied nuclear fusion and nanotechnology, and he is on his way to solving the energy crisis.

It all started with Legos - after he learned nanotechnology to make robots take off. The seventh grader then got an idea inspired by the sun.

"Solar it seems underused, and there are only a few problems with it," Yuan said.

"This solar cell can't be generating this much electricity, it can't be absorbing this much extra light," he recalled thinking.

If he is right, solar panels with his 3D cells would provide 500 times more light absorption than commercially-available solar cells and nine times more than cutting-edge 3D solar cells.

"Which would make solar energy actually a viable energy source for the Pacific Northwest," Yuan said.

His next step is to get a manufacturer and market it.

What if Electricity Was FREE???

clipper's remarks: The life story and work of Nikola Tesla. He invented AC electricity, Neon Lights, Radio transmission, The Electric motor, Wireless electricity transfer, Remote control, Hydraulics, Lasers, Space weapons, Robotics, and many, many more things.

As Tesla claimed to have invented a way to harness free energy from the voltage difference in the ionosphere that causes lightning, he was seen as a threat to the world energy economy and most of his inventions were classified for national security by the US government.

A lot of his discoveries in physics have not been released to the public, despite being invented nearly 100 years ago. In 2006 the first company publicly announced it could successfully power items by remote power without wires, (news.bbc.co.uk/1/hi/technology/6129460. stm) something Tesla had invented nearly a century ago.

Tesla showed that gravity does not pull us to earth, but rather is a force gradient present everywhere, even in space. The earth acts as a shield from the push of the energy forces that would be under us. Newtonian physics was refined: 2 objects do not attract to the inverse square of their distances: they mutually shield from gravitational "push"
Tesla wanted everyone to have FREE ELECTRICITY, so he invented a FREE ENERGY machine to convert the high potential energy gradient (present everywhere) to electricity. Unfortunately, his notes disappeared when he died. Research based on his has produced different forms of a FREE ENERGY convertor . Tesla's convertor gave much more power than current re-creations.

The Problem with Solar Energy

A couple of weks ago, we had a colloquium talk by Peter Persans of RPI, who is working on developing new types of solar cells using amorphous silicon and "quantum dots."

In order to meet the energy needs of the US entirely with solar power, we would need to cover 0.2% of the land area of the United States with photovoltaic cells, roughly equal to the area of paved roads in the US. And that's using solar cells with an efficiency of 50%, not too far below the theoretical maximum for a single-layer device.

But efficiency isn't the only problem: He pointed out that in order to build that sort of solar energy infrastructure, we would need to produce and install 2,000 square kilometers of solar cells a year for twenty years.

it wasn't entirely downbeat: he did note that great strides have been made in the production of solar cells, and described some intriguing possibilites using "quantum dots" embedded in silicon as a means of increasing the bandwidth of light that produces useful electricity.

Stormy Jupiter reveals more secrets.

clipper's remarks: Jupiter has a metallic Hydrogen core that creates a Magnetosphere similar to the one created by Earth's Iron core. Scientists have known that Jupiter generates more energy than it receives from the Sun, but how it affectes the Atmosphere below the surface layer of clouds was unclear. They are still trying to work out the way the Atmosphere is affected by the combination of these energy sources, but they are learning to make a distinction between the two effects. This data shows effects that to be a result of Energy generated by Jupiter. They are thought to be below any possible influence of the sun. (Of course the scientists could always be surprised again. That seems to happen fairly often.)

Two enormous storms on the surface of Jupiter have provided important clues about the true nature of the solar system's biggest planet, astronomers say.

Professor Agustin Sánchez-Lavega from Universidad País Vasco in Spain and colleagues report their findings in today's issue of the journal Nature.

Jupiter's atmosphere is wreathed in a blanket of thick cloud that prevents telescopes from observing deeper into the planet.

Among the only clues are occasional storms, which burst through this cloud layer and appear as light patches within the planet's characteristic stripes.

In March 2007, a team

led by Sánchez-Lavega recorded two such events on Jupiter, using the Hubble Space Telescope.

amateur astronomers

relayed their data to the

team.

"The main thing the modelling showed was that there seems to a jet stream effect below the influence of the sun," says Valimberti.

"That indicates it is being generated by something internal within the planet, some kind of internal heat source."

Self-luminous material glows for 12 years

Litroenergy is a new type of material that emits light for 12 years without needing electricity or sun exposure. The self-luminous micro-particles are called Litrospheres and are said to be non-toxic and inexpensive. The light is said to be equivalent to a 20 watt incandescent bulb (lumens please?).

The litrospheres give off a continuous illumination, and can be designed to glow in any color. They can be injection molded or added to paint. The company that invented the material, MPK Co., predicts that first applications of Litroenergy will be in safety equipment such as safety tape and life rafts. Currently, the cost to light up a 8 ½ x 11 piece of plastic 1/8” thick is about .35 cents. Note: The press release says .35 cents but I think the figure is actually 35 cents.

Genetically modified green algae could one day produce stored energy in the form of hydrogen gas, say Australian researchers, fuelling a hydrogen economy.

Associate Professor Ben Hankamer of the University of Queensland and colleagues report they have increased the sunlight-capturing efficiency of algae that can pump out hydrogen.

If successfully scaled up, the researchers say this could complement or be an alternative to our present carbon-based economy.

"We urgently need to develop and install new CO2-free energy production systems. Our systems offer one solution for this," the researchers say.

They report their findings in the latest issue of the Plant Biotechnology Journal.

The researchers have been studying single-celled photosynthetic algae (Chlamydomonas reinhardtii).

A major problem is the algae are inefficient at capturing sunlight,

they have now used RNA interference (RNAi) to engineer a strain of algae to make the process more efficient

Energy drinks jolt blood pressure

clipper's remarks: There are warnings on these drinks which tell consumers to limit the number of drinks per day, but these are more seen to be suggestions. Often they are consumed in large numbers even if only to maintain the 'buzz' Of course caffeine is a traditional means of achieving the same effects, but very often the negative effects of caffeine and taurine combined are not considered, because they do not seem to be relative to young and healthy people. The caffeine and taurine with their diuretic effect can make the drinker thirsty. While the effects were considered to be of more concern for people with already high blood pressure and heart problems, the volumes that are consumed, and the likely continued use warrants more study. There is the chance that benefits can be seen from the studies. For example they could be used in cases of low blood pressure.

High-caffeine soft drinks may do more than give people a jolt of energy. They may also boost heart rates and blood pressure levels, researchers say.

The results of a small study prompted the researchers to advise people who have high blood pressure or heart disease to avoid energy drinks because they could impact their blood pressure or change the effectiveness of their medications.

The drinks generally have high levels of caffeine and taurine, an amino acid found in protein-rich foods like meat and fish that can affect heart function and blood pressure, the researchers say.

"We saw increases in both blood pressure and heart rate in healthy volunteers who were just sitting in a chair watching movies. They weren't exercising. They were in a resting state," says James Kalus of Henry Ford Hospital in Detroit, who led the study.

The increases did not rise to dangerous levels in the group of 15 healthy volunteers, whose average age was 26, the researchers say.

Total chief warns on oil output

The world’s capacity to produce oil will fall well short of official forecasts, the chief executive of Total warned on Wednesday

In an unusually stark prediction for the head of one of the world’s biggest oil companies, Christophe de Margerie, CEO of the French group, said it would be difficult to reach even 100m barrels a day.

“100m barrels [per day] . . . is now in my view an optimistic case”.

He added: “It is not my view: it is the industry view,

“We have been, all of us, too optimistic about the geology. Not in terms of reserves, but in terms of how to develop those reserves:

The International Energy Agency, the rich countries’ watchdog, in its “business as usual” projections, has said oil supply will reach 116m barrels a day by 2030, up from about 85m b/d today.

He said the industry had also “misunderstood” that resource-rich countries would want to preserve some of their best oil fields for the future, while offering smaller and more difficult fields to foreign investors.

LEDs to replace city street lights

clipper's remarks: The city near Detroit Ann Arbour, is replacing traditional bulbs with white LEDs,
which last an average of five times as long, and the energy saving will be the equivalent of taking 400 cars of the road.

By JEFF KAROUB

How many Ann Arbor city workers does it take to screw in a light bulb?

Soon, none.

Instead, they will be installing light-emitting diodes, or LEDs, to replace about 1,400 street lights.

The eco-friendly city about 30 miles west of Detroit says it will be the nation's first to convert all downtown street lights to LED technology, which uses less than half the energy of traditional bulbs and could save the community $100,000 a year.

"LEDs pay for themselves in four years," said Mayor John Hieftje, who announced the city's plans this week as it joined Raleigh, N.C., and Toronto in the LED City initiative, an industry-government

group working to evaluate, deploy and promote LED lighting.

"They provide the same light, but they last 10 years. We had to replace the old ones every two years."

LEDs, small chips usually encased in a glass dome

usually gave off red or green light

a scientific breakthrough in the 1990s paved the way for LEDs that produce white light

Commercial wave-powered water desalination and electricity generation is one step closer to reality, report Australian developers.

Trials of a technology called CETO have yielded promising results, says Dr Michael Ottaviano of Carnegie Corporation, which is developing the system in the southern hemisphere.

The tests, carried out in Fremantle, Western Australia, verify predictions of how much electricity and water the technology can produce under various wave conditions.

"We've found a perfect correlation between the results our models predicted and what we've actually measured in the ocean, which is a major technical milestone," says Ottaviano.

Click here to enlarge an animation of how the wave farm would work

The CETO technology, first conceived by

Alan Burns in 1975, consists of submerged buoys connected to seawater pumps fixed to the seabed.

As each buoy moves back and forward

it generates energy

to drive a reverse osmosis desalination plant as well as hydroelectricity turbines.

When he heard on television that gravity couldn't be used as a form of energy, Bob Kostoff set out to prove Discovery Channel wrong.

"I said, 'That doesn't make any sense,'" said the Little Britain resident, using dropping a cement brick from a standing height as an example.

If you were to place your hands a few centimeters off of the ground to try to stop it before it hits the ground, you wouldn't be able to because of the energy powering the bricks fall, he said last Friday. With that concept in mind, Kostoff sought to make a 'perpetual motion machine' that could offer a clean, alternative source of power using gravity as 'fuel.'

After about four years of planning and development through trial and error - including about a year-and-a-half creating the designs on paper - Kostoff reached his goal.

He now owns the patent on the technology to prove it.

While Australia gears up for new coal-fired power stations, the US has taken a dramatic turn - setting its sights on the sun. Two of America's biggest power companies have unveiled plans for a multi-billion dollar expansion of solar power supply. And the man behind it all is an Australian scientist who tried and failed to be heard here

What makes the announcement more significant is that the utilities are confidently predicting that their solar power will soon be providing base-load electricity

that is, day and night - at prices competitive with coal

Those associated with the project believe it could signal a paradigm shift in electricity generation

House slaps $16 billion in taxes on oil industry

Lawmakers also pass broad incentives for renewable energy, conservation

WASHINGTON - Declaring a new direction in energy policy, the House on Saturday approved $16 billion in taxes on oil companies, while providing billions of dollars in tax breaks and incentives for renewable energy and conservation efforts.

Republican opponents said the legislation ignored the need to produce more domestic oil, natural gas and coal. One GOP lawmaker bemoaned "the pure venom ... against the oil and gas industry."

The House passed the tax provisions by a vote of 221-189. Earlier it had approved, 241-172, a companion energy package aimed at boosting energy efficiency and expanding use of biofuels, wind power and other renewable energy sources.

The bill is aimed, among other things, at wind power, biofuels and other renewable energy sources.

Prototypes of an energy-generating dance floor have been tested at various events, including Live Earth, earlier this year.

"We go one important step further by recognising the clubber as a source of energy," say Rotterdam-based concept developers, the Enviu network and architecture firm Döll - Atelier voor Bouwkunst.

The club aims to save external energy use with a special dance floor that captures the energy of dancers and uses it to power lights.

New technology could also help save water by capturing the sweat of dancers to flush toilets, say the developers, who are working with Delft University of Technology to develop the new technologies

This 12inch miracle tube could halve heating bills

It sounds too good to be true - not to mention the fact that it violates almost every known law of physics.

But British scientists claim they have invented a revolutionary device that seems to 'create' energy from virtually nothing.

Their so-called thermal energy cell could soon be fitted into ordinary homes, halving domestic heating bills and making a major contribution towards cutting carbon emissions.

Even the makers of the device are at a loss to explain exactly how it works - but sceptical independent scientists carried out their own tests and discovered that the 12in x 2in tube really does produce far more heat energy than the electrical energy put in.

The device seems to break the fundamental physical law that energy cannot be created from nothing - but researchers believe it taps into a previously unrecognised source of energy, stored at a sub-atomic level within the hydrogen atoms in water.
