WHAT CAN JAPAN TEACH US ABOUT THE FUTURE OF POWER?

As we see the events at the Fukushima power plants unfolding on a daily basis, and our actual ability to contain their toxic radioactive materials put to serious doubt, we naturally should be thinking: what do we replace these with? Surely, nuclear reactor power is not a safe option any more. What will it take for there to be a total ban on any new reactors being built? Yet another catastrophe?
Perhaps three incidents over the course of twenty years or so is a sign that we should be looking toward tomorrow, to the future, and asking ourselves what the future of power will be.

One option could be tidal power.

In 2007 CREST provided some funding assistance two University of Auckland environmental engineering students to research the full life carbon cycle of four NZ sustainable energy sources: tidal, wind, hydro and geothermal. Their findings are summarised below:

Full life carbon Embodied energy Kilo joules per kilowatt hour Carbon dioxide emissions Grams of CO2 per kilowatt
Tidal 42 1.8
Wind 70 3.0
Hydro 55 4.6
Geothermal 105 6.3
Combined cycle gas N/A 200-300
Coal N/A 400-1,000
The study found that tidal is amongst the cleanest (in CO2 terms) of renewable electricity sources. Wind is less predictable and consistent, increasing the footprint. Hydro uses huge amounts of energy for the steel and concrete in the dams and waterways, and for the energy used initially for vegetation clearance and roading. Geothermal uses high quality of materials with high energy contents to operate in hostile geothermal environments, that require frequent replacement.

Coal and gas produce hundreds of times more emissions than renewable sources.

NZ national average emissions are about 210 grams CO2 equivalent per KWh which is internationally low due to the high contribution of hydro to NZ electricity production. Figures for Huntly coal are 958 g CO2/KWh and Otahuhu B gas 372 g CO2/KWh, according to Energy Modeling Consultants Ltd November 2008 report.

Tidal energy short and long term marginal costs seem economically similar to those of wind power, and those of tidal energy can only improve as more turbines are deplyed around the world.

Another option, much like tidal power only more expensive to implement, is hyrdoelectric power – that is, generating electricity from the flow of a large body of water, like a dam or a reservoir. A famous example of a gravity dam is the Hoover dam. This form of electricity generation has been around a long time, but it is limited to site where there are already large bodies of water, or locations where such a body of water can be created.

Of course there is wind power, derived from turbines.

What are wind turbines made of?

The towers are mostly tubular and made of steel, generally painted light grey. The blades are made of glass-fibre reinforced polyester or wood-epoxy. They are light grey because this is the colour which is most inconspicuous under most lighting conditions. The finish is matt, to reduce reflected light.

How big are they?

Large modern wind turbines have rotor diameters ranging up to 65 metres while smaller machines (around 30 metres) are typical in developing countries. Towers range from 25 to 80 metres in height. For more information, see the BWEA factsheet on wind energy technology. Information about specific wind farms is available on our interactive map of UK wind.

How does a wind turbine make electricity?

The simplest way to think about this is to imagine that a wind turbine works in exactly the opposite way to a fan. Instead of using electricity to make wind, like a fan, turbines use the wind to make electricity.

Almost all wind turbines producing electricity consist of rotor blades which rotate around a horizontal hub. The hub is connected to a gearbox and generator, which are located inside the nacelle. The nacelle is the large part at the top of the tower where all the electrical components are located.

Most wind turbines have three blades which face into the wind; the wind turns the blades round, this spins the shaft, which connects to a generator and this is where the electricity is made. A generator is a machine that produces electrical energy from mechanical energy, as opposed to an electric motor which does the opposite. You can see an animation of this here.

How strong does the wind have to blow for the wind turbines to work?

Wind turbines start operating at wind speeds of 4 to 5 metres per second (around 10 miles an hour) and reach maximum power output at around 15 metres/second (around 33 miles per hour). At very high wind speeds, i.e. gale force winds, (25 metres/second, 50+ miles/hour) wind turbines shut down. For more information, see the BWEA factsheet on wind energy technology.

How fast do the blades turn?

The blades rotate at anything between 15-20 revolutions per minute at constant speed. However, an increasing number of machines operate at variable speed. For more information, see the BWEA factsheet on wind energy technology.

A modern wind turbine produces electricity 70-85% of the time, but it generates different outputs dependent on wind speed. Over the course of a year, it will generate about 30% of the theoretical maximum output. This is known as its load factor. The load factor of conventional power stations is on average 50%.

Another option being talked about at the moment is to cover existing skyscrapers with solar panels.

From energydigital.com:

It’s about time a company figured out a way to make use of the immense square-footage available on the surface of a skyscraper, let alone the fifth largest freestanding skyscraper in the world! Pythagoras Solar, an alternative energy start-up, has struck a novel deal with the owners of the Chicago’s Willis Tower—formerly the Sears Tower. Pythagoras plans to cover the skyscraper’s south-facing side with solar panels to create a vertical 2 MW solar farm.

The Willis Tower has 108 stories, and during the summer, solar glare and building cooling costs have become a problem. The solution: solar panels that offset the skyscraper’s energy needs while providing window shade.

Pythagoras Solar’s window pane solar panel design—called high-density photovoltaic glass units (HD-PVGUs)—acts as slat blinds, blocking some sunlight from entering the building but still providing a view of the city below. The glass panes contain thin layers of monocrystalline silicone pressed between glass sheets. Internal plastic prisms direct angled sunlight while allowing diffused sunlight and indirect reflected sunlight into the building, resolving intense summer glare issues while harnessing the sun’s natural energy.

The Willis (Sears) Tower solar farm is expected to provide as much power as a 10-acre ground installation. If the project—still in the planning phase—is a success, it could set a precedent for using skyscrapers all over the world for solar energy generation. This is such a smart and novel way of using space and saving acres of land for conservation purposes or other development ventures.

I think this is an interesting proposition, but it carries the same disadvantages as wind power. It is unpredictable, as opposed to the regular nature of tidal energy – although tidal energy does not produce as much energy as the other methods.

And what about space?

One option is to have a satelite in geo-synchronous orbit, generating power from high-efficiency Gallium-Arsenide photovoltaic arrays. They would then send the energy to Earth in the form of microwave beams. The risk here is that if the process of beaming the microwave energy to the surface is not 100% efficient, where is the leakage going? Obviously into the atmosphere, into the environment. Further, if the microwave beam were to stray off-course, the resultant damage could be quite extensive depending on the strength and volatility of the beam being used.

Could we use space tethers to generate energy, spinning freely in orbit and sending the electricity to the surface through a tensile cable?

Or perhaps a space mirror, reflecting permanent sunlight onto specific spots on the Earth’s surface, where we would have banks of solar cells providing all our energy needs.

This would certainly eliminate the unpredictability inherent in solar energy. But there would be the affect this would have on the habitat to consider. And in a way when you start to do stuff like this, changing the day and night patten of an area and therefore altering its ecology, we start to move into the realms of terraforming.

All things to consider. Will the future have every coast lined with tidal generators? Every hill covered with wind turbines? Certain places on Earth made to experience perpetual day, the ground covered with mile after mile of solar cells? Will we have satelites in orbit, sending us electricity through tethers hooked to the ground? As ugly as these options seem to be, are they really much worse than the prospect of a nearby nuclear power station going up?

The governments of the world should put a universal ban in place on any new reactors being built, and they should also agree to a plan to shut-down and do-away with the reactors they already have. The earthquake and tsunami in Japan has shown that it only takes something like a natural disaster, which you cannot predict, to make things like nuclear reactors ecologically damaging. And there is the human cost of such disasters to take into account – the true effect that the damaged reactors at Fukushima will have on the Japanese in the coming months can only be guessed at. With radioactive material seeping into the soil and the sea, what will be the eventual cost on Japanese agriculture and fishing industries?

We have yet had a full-blown worst-case scenario happen with a nuclear reactor – but that is not to say that it won’t happen. We’ve done allright out of nuclear energy, but I think it’s time to move onto something else. Just as we view fossil fuel generators as infeasible for future energy production, because of the cost they have on the environment, and because they are not renewable, so too must we view nuclear energy production in the same light.

My personal hope is that we will harness the power of the oceans and the sun for future energy production. Obviously, as what is happening in Japan right now shows us, resting the hopes of our futures in nuclear energy is extremely naive.

THE BELL: PART TWO

The 1965 crash of a supposed UFO at Kecksburg is often referred to in UFO-circles as the “Roswell of Pennsylvania.”

A brief description from ufoevidence.org:

On December 9 1965, hundreds of witnesses in southern Canada, Michigan, Ohio and Pennsylvania observed a UFO crash from the sky. In March 1966, scientist and UFO investigator Ivan Sanderson compiled an account from various eye witness stories.

The object took six minutes to pass the observed trajectory, from which Sanderson calculated a speed of 1,600 km/h, which, if accurate, would rule out a meteor. Several pilots spoke of being buffeted by shock waves as the thing passed them. There were also stories of a sonic boom and vibrations felt on the ground. The smoke trail was so intense that it remained visible for up to twenty minutes. During the final few miles of its flight the object seemed to change course.

After the impact the police set off the forest. They were subsequently chased away by the military. A few hours later the military team told them they had found nothing.

In January 1980 UFO investigator Clark McClelland interviewed the assistant fire chief of Kecksburg, James Mayes, and Melvin Reese, another fireman. They reported that their team had come within sixty meters of the object. They had seen an object on the ground that had smashed its way through the trees. Mayes explained how the military had cordoned off the woods and had established a temporary base, complete with telecom link. Fire chief Robert Bitner later confirmed this story. He also said had seen an object that was 1.8m high, 2m wide and some 5m long, clearly not an aircraft. It was resting at an angle on the ground as if it had impacted nearly horizontally. Another fire officer, ‘Pete’, stated he had seen a ring of bumpers around it into which were described some pictorial symbols. Being of Polish decent he could read Russian and stated that they were not Russian.

Researcher Ray Boeche file a Freedom of Information request for more data on the incident. In 1985 30 pages of data were procured. It was insignificant information, except for a memo that said a three man team had been dispatched to the site to pick up an object. The final conclusion of the file was that the UFO was a meteor.

A theory has been proposed that the object was a crashed Russian satellite (Cosmos 96). However, NASA has released data that say that Cosmos 96 reentered Earth’s orbit on December 9, 3.15 a.m. The crash took place 13 hours later.

After the US TV series Unsolved Mysteries had reported the case two new witnesses came forward. One was a USAF officer at Lockbourne AFB (near Columbus, Ohio). In the early hours of December 10, a truck arrived by the little used back gate of the base and he was ordered to patrol it. It was a flat-bed with a large tarpaulin on the surface covering a conical object. He was told to shoot anyone who tried to get too close. He was advised the truck was bound for Wright Patterson AFB, which is the reputed home of other crashed saucers.

The other witness was a building contractor who was asked two days later to take a load of 6,500 special bricks to a hangar inside Wright Patterson. When he sneaked a look inside the hangar he saw a bell-shaped device, some 4m. high sitting there. Several men wearing white anti-radiation style suits were inspecting the object. After he had been escorted out he was told that he had just seen an object that would become common knowledge in 20 years time.

The object was a bell-shape. Many have taken this as a direct link to the myth surround die glocke, the mythical Nazi experiment (Read Part One of this article HERE)

From abovetopsecret.com, which by the way provides a brilliant and in-depth article on the incident, the bell is described by one witness as “a bronze colored, acorn shaped, and 12 by 25 feet in size object with a raised “blunt” end that had strange markings on it.” When you look at depictions of what the ‘acorn’ looked like, it is easy to conclude that there must be a link of some sort with that and the bell shaped device the Nazi’s were supposedly experimenting with twenty years previous.

To me, what makes the Kecksburg incident seem like such a genuine cover-up, is what happened to local reporter John Murphy. Go HERE to learn about the role Murphy had to play in the Kecksburg incident.

How strange that after being silenced regarding the crash, or whatever it was, he was killed in a hit and run? Was he targeted by government agents after being deemed a liability?

The Kecksburg doesn’t get as much exposure in the press as Roswell, but it is just as mysterious.

See the doc below:

Hopefully these two posts have allowed you to learn a little bit about the mystery surrounding die glocke, and the Kecksburg UFO crash. Whilst there’s nothing new I can write about these, I can link you to some great articles that already been written about them, which is what I’ve done.

Let me know your thoughts below. What do you think about die glocke? What do you think about Kecksburg? Is there a link between the two?

FOUR INVENTIONS THAT COULD HAVE CHANGED THE WORLD

Great reading at friedpost.com about the four inventions that could have potentially changed the world. These being Time Travel, 100% Efficient Solar Cells, a Water-Fuelled Car, and real Teleportation technology.

Here is an excerpt:

During the last century there were claims of some mysterious experiments in which time travel happened and the most popular is the Philadelphia Experiment that was intended to make invisible a US destroyer ship. The ship was called USS Eldridge and on July 22nd, 1943, the destroyer escort became almost invisible and some people at the scene claimed that a “greenish fog” appeared instead. These claims were strengthened by the fact that some crew members experienced serious nausea after the experiment.
Well, the US Navy didn’t stop here with the experiments and on October 23rd, the USS Eldridge totally disappeared from the surface of the sea. Afterwards, the ship was spotted at US naval base in Norfolk, Virginia, then after a few moments it was spotted once again in Philadelphia and it appeared to be an accidental case of teleportation.
As if this wasn’t strange enough, Al Bielek and Duncan Cameron, claimed that they leapt into “hyperspace” from Philadelphia to Norfolk and they “woke up” at a US Air Force Station in Montauk Point, Long Island in the year of 1983. The two members of the crew also said that they met with John von Neumann there, however, von Neumann died in 1957. We don’t know what to say about that, but people at the scene said that the crew members who were part of the experiment suffered from severe mental illnesses like schizophrenia.
In order to make it a little more weird, a member of the crew called Jacob L. Murray disappeared. Other bad things happened with the Philadelphia Experiment as five members of the crew were fused to the metal deck or on the bulkhead as some “special spots” caught fire. Although, the US Navy stopped the tests immediately, it seems like the Philadelphia Experiment was continued with the Montauk Project which consisted of a series paranormal experiments led by the US Government.

Allegedly, there were many experiments conducted at the Montauk Air Force Station that were destined to provide the US Navy and Army with “psychological warfare” technologies which also included time travel. Although it was regarded as a conspiracy theory, the first reports of the Montauk Project appeared in the early 1980s.
These rumors were based on Carl Allen’s testimony who said that the Philadelphia Experiment did happen. It seems like Carl Allen was mentally unstable therefore some people believed him and some didn’t. His story was nourished by others who claimed that the Philadelphia Experiment aka Project Rainbow was continued by researchers from the original experiment.
They started the work at the Brookhaven National Laboratory, Long Island, New York, and they called it the Phoenix Project. After a while, they moved to another place in Montauk, New York, as the researchers needed more space and a more advanced radar dish. Although they didn’t try to replicate the Philadelphia Experiment, their main goal was to develop a gun that would cause severe mental illnesses like schizophrenia. Well, we don’t know very much about the results of the Montauk Project, but some reports say that it was finished in 1987 and that the Montauk Point is not opened for public due to environmental contamination.

I wonder which four inventions I would pick as potentially world-changing. Perhaps cold fusion technology? Quantum computing? But the four choices in the piece I think are good choices
