A Global Disaster From the Perfect Solar Storm
A Global Disaster From the Perfect Solar Storm
The average solar cycle lasts for eleven years. The cycle includes a minimum of solar activity and a maximum. The sun is unusually quiet right now and has been for some time but there should be an increase in solar activity at some point in the near future.
The best current scientific estimate for the next solar maximum is 2012. If this estimate is correct, there is still a few years to try and prevent the potential of a future global disaster. A disaster that would begin on the surface of the sun and could end with tragedy on earth.
The surface of the sun is a mass of plasma that contains highly charged energy particles. Once in a while, some of these particles escape the suns surface and a mass of plasma travels through space on the solar wind. This process is known in scientific terms as a coronal mass ejection but it can also be called a solar storm.
A disaster for the planet would occur if a solar storm reaches and hits the earths magnetic shield in just the right way. If it were to happen, millions of people would lose their lives and the planet would be thrown into chaos as the technology that has become crucial to every day living suddenly gets taken away.
The perfect solar storm will start with skies that will be filled with a bright red aurora. However, soon everything will become dark as every electric bulb becomes devoid of light. The storms damage to the electric grid would be caused through an increased DC current. The runaway current would knock out and melt hundreds of key transformers within minutes, cutting off power for hundreds of millions of people.
Those damaged transformers cannot be repaired only replaced and installing a replacement takes a well-trained crew a week or more. Its incredible to consider that most major electrical utilities have just one or two suitably trained crews available for these type of transformer repairs. In addition, there are only a few spare transformers available and the rest would have to be built to order. Its a process that can take nearly twelve months.
So, the power blackout from the perfect solar storm would last for months but its not just the absence of light that would be the problem. Drinking water would still come through the taps for maybe half a day after the storm. With no electricity to pump water from reservoirs, there would be no more tap water after that.
The electric grid is necessary for almost all natural gas and fuel pipelines to operate. As a result, fuel and natural gas will quickly run out and without food delivery, supermarket shelves would soon become bare. Soon it would become necessary to control public hysteria and the military would have to be called in to restore civil order
There will be no power for heat, cooling or refrigeration until the grid is repaired and after their back up generators run out, hospitals will not be able to provide modern healthcare. A lack of water and food will result in spreading disease but Pharmaceutical companies without electricity will not be able to produce the necessary medicine.
Of course, many will say that this is absurd science fiction and it cannot happen here, but this chilling disaster scenario was outlined in a report released last January (funded by NASA) by the US National Academy of Sciences (NAS).
The fact is that a storm from the sun did hit the earths magnetic field in 1859. The effect of this solar storm on earth became known as the Carrington Event. The event was named after the amateur astronomer who observed two patches of intensely bright and white light emanating from a large group of sunspots that may have produced the event.
The solar storm that produced the Carrington Event created a red aurora across the planet from the poles to the tropics. Throughout the world, telegraph systems crashed, machines burst into flames, and electric shocks rendered operators unconscious. Compasses and other sensitive instruments reeled as if struck by a massive magnetic fist. It can happen again and the technology of the planet is now much more advanced and vulnerable.
The next solar maximum is estimated to return in about three years. A global disaster from the perfect solar storm can be prevented with proper contingency planning. There is still time for the government to be proactive and prepare to avoid disaster by creating a potential response to quickly repair the damage to the electric grid from the perfect solar storm.

Some Eco-Friendly Green Thoughts
How often when you go to the grocery store are you asked if you want paper or plastic grocery bags? Well the best answer to that would be NEITHER. To keep the U.S. stocked with paper and plastic grocery bags, takes about fourteen million trees and twelve million barrels of oil every year! Investing in a few reusable bags makes a lot of sense.
Think about those little paper receipts you get at the gas pump and the ATM machine. If all people would simply note it in their checkbook, or in a small notebook when they made a purchase or withdrew money, it would be saving enough paper to encircle the globe fifteen times!
If every American would by one roll of recycled paper towels instead of the others, it would save over half a million trees. And how about turning the car off when you are waiting for someone, in the drive-thru lane or stuck in a huge traffic jam? When a car idles for more than a minute it is polluting the air and wasting your gas.
Cordless phones are replacing conventional phones. But think about it… sitting in a recharging cradle and using up your electricity twenty-four hours a day and every day of the week! Replace one or two cordless phones with your old conventional ones and you’ll save energy. The old fashioned ones use only a tiny bit of electricity, and will work when the power is off. If you insist on the convenience of cordless phones, make sure the ones you do get are Energy Star-rated, for high energy efficiency.

Historical Conservation Efforts
How often have we come across lovely historical sites suffering from neglect and misuse? Every country needs to take good care of its historic places. Because things like malls, stadiums and highways can be built again. But a historic place which is neglected and misused will lose its glory and slowly disintegrate into zilch. And no amount of action plan or noble intentions can ever bring a historic place back to its former glory when it has been totally neglected and abused by us. The oldest of historic sites can be preserved for the future generations if we have a proper plan for their conservation.
Conversation of historic places requires a systematic approach. If the historic site is conserved with the help of a proper plan, it will show amazing results. While chalking out a plan for the conservation of historic sites, it’s very important to keep the costs under control. If the costs go up to an unwanted level, it will draw criticism from the general public and act like a death sentence for the conservation of other similar projects in the future.
The first thing which should be done by the restoration experts is to check the age of the historic site. This can be easily achieved by conducting a series of scientific tests. It can also be done if there are public or archaeological records of the site. Once we know the actual age of the historic site, we get to know the actual worth of the site – this doesn’t mean that if a site is not very ancient – it’s not worth taking care of.
Also check the sturdiness of the materials which have been used on the historic site. This will need a proper list of all the materials used on all the structures found on the site. Factors such as the effect of temperature, humidity, weathering, fire, air pollution, storms and flood on the material found on the site needs to be studied in detail, so that best possible plan to prevent further degradation of the site can be prepared.
Don’t forget to note the architectural design of any structures present on the site. This is needed to take help of conservation experts according to the style they specialize in. Taking the help of the best of experts who are not competent in the architectural design displayed at the historic site would create a major problem for your conservation project.
Your team of conservation experts also need to keep a track of all the past repairs and changes made on the historic site. The problems faced by the previous restoration team while restoring or repairing the historic site too needs to be researched and noted down. Always remember materials like wood and leather rot quite easily, on the other hand stone articles and pottery items always manage to survive better. Once you have finished your complete study of the historic site, you can then do the restoration part of the site step by step in a phased manner till it is complete. You might even have to restrict the number of visitors, once it has been restored, as although the site has got its former glory, it might not be in a state that it can be exposed to an endless number of people everyday.

Water Efficiency
Water Efficiency
In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.
You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.
You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.
Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.
Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.
For a simple reason. It takes a lot of water to produce electricity.
How much? 5% of all US water? 10%? Can’t be as high as 25%?
Electricity and water?
I thought the issue was fossil fuels and greenhouse gases
The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.
Their grand total: 408 billion gallons per day withdrawn for all uses.
The number 1 spot, weighing in at 48%, was thermoelectric power.
Irrigation earned the runner-up prize at 34%.
The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.
How much water is used in generating electricity?
Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.
Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.
According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.
The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.
Nationally:
- Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
- Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
- Geothermal power plants add another 2 billion or so gallons a day.
- Most renewable energy technologies require little or no water for cooling.
These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.
Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.
How much is 3 billion gallons per day?
The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.
Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.
How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.
Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.
48% of all water use: We’re Number One!
How much is 195 billion gallons per day?
Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.
How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.
So, let’s get a higher-level view to help us.
Lake Erie holds 116 cubic miles of water.
Nationally, thermoelectric power uses 195 billion gallons a day – or 64.2 cubic miles a year.
We drain Lake Erie every 22 months.
But the water used is returned to its source.
So what’s the issue about water use?
Power generation returns 98% of the water back to its source (bay, lake, river, ocean).
It’s the environmental consequences.
The Pace Energy and Climate Center explains it neatly:
Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.
Examples include:
- The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
- At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
- The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)
The diversion of water out of the river removes water for healthy in-stream ecosystems:
- Stretches below dams are often completely de-watered.
- Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
- A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
- By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
- The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
- This often eliminates native populations of fish and other wildlife.
- Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
- As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.
The cleanest kilowatt is the one never used:
Back to those compact fluorescent lamps and LEDs
PowerScorecard.org explains the solution:
By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.
They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.
In short, reduce your use of electricity.

How to Address Contaminated Land Issues
How to Address Contaminated Land Issues
Under the relevant European Directives, an Environmental Statement is the formal product of an Environmental Impact Assessment. Environmental Statements are often organised in a way that describes the environmental baseline, mitigation and effects for each type of environmental receptors: ecology, water resources, archaeological resources, human beings etcetera. Contaminated land is often managed in the same ways as the various environmental receptor groups, although it is principally a cause of impacts rather than a receptor. It also often refers to a pre-existing condition and its damaging effect is on a variety of different receptors such as human health, structures and buildings, surface water features, groundwater features and ecology. This often means that land contamination specialists struggle with integrating the issue in a logical manner in an Environmental Statement. Sticking to the structured approach of an environmental statement is essential to ensure a clear description of the existing environmental condition, the potential impacts and the actions taken to avoid, minimise, offset or manage the impacts. This article is based on UK practice and legislation, although fundamentally the issues should be similar within other contexts.
Contaminated land is in many countries considered on a source-pathway-receptor basis. This is important to understand the impact land development can have on the issue of contaminated land. Development can interfere with any of these three elements. It can introduce sensitive receptors by changing the use of land, for instance by building new residential units on a site that was previously used for heavy industry. New pathways linking pre-existing contamination with an existing receptor can be formed, for instance when piling through a non-permeable layer connecting a layer of contaminated soils with a deep aquifer. Finally by introducing pollutants on the site a development project can introduce a potential source of contamination.
The second element to consider is the structured approach of an environmental statement. Apart from the introductory and procedural elements described in the environmental statement, a good environmental statement comprised the following sections:
- environmental baseline conditions
- potential environmental impacts
- mitigating measures
- residual environmental impacts
There should be a logical relation between the different sections. Any receptor that is affected and described in the section about the potential impacts and effects should have been introduced in the section describing the baseline. Any material impact should be assigned a mitigation or management action etc. Implementing this structure allows a clear description and understanding of the environmental impacts and the way it will be managed.
Applying these principles to contaminated land will result in a baseline condition section that describes the current sensitive receptors that are present within the potential sphere of influence of the development, the sensitivity and importance of these receptors, the presence of any pre-existing contamination and the presence of actual and potential pathways. The next section, potential environmental impacts or effects, first considers the impacts that the development will have in terms of the introduction (or removal) of sensitive receptors and the creation of new pathways between existing and potential pollution sources and receptors. In addition this section will describe the potential environmental impacts that are associated with the introduction of new sources of contamination. In the third section, mitigating measures, a description of the actions to mitigate each of the impacts that may occur should be provided. Finally a statement of the residual impact of the development is provided in the last section: residual environmental impacts.

Germ of an Idea – A Modern-Day “Roman” Aqueduct For Florida
The west coast of Florida remains trapped in an ongoing drought. In Pinellas and Hillsborough Counties (Tampa and St. Petersburg/Clearwater) severe restrictions on water use are in place. Even the use of reclaimed water for lawns and gardens is now restricted. The rainy season is not yet here; but in past years the amount of rainfall received during the wet months was far below the historical average, so that reservoirs and ground water supplies have never had a chance to recover.
The situation is quite different in northern Florida, in the Panhandle and all across the State close to the Georgia border. The weather in those parts of the State is generally wetter, and more consistently so, than the weather farther south.
Yesterday, our local St. Petersburg Times carried a story (with photographs) of the damage which is now being inflicted in Madison County (which borders Georgia) by floodwaters from the Withlacoochee and Suwannee Rivers. The storms which produced the rain moved from west to east across the Panhandle over the past week, to the point at which the Withlacoochee crested at 89 feet, four feet above the record set in 1948. So far, the rising floodwaters have destroyed or caused severe damage to almost 200 homes and lesser damage to 500 more, all areas combined. Two people are known dead, and one person is missing.
Quite apart from the possibility of reducing the tally of deaths, personal injury, and property damage which even a partial remedy for river flooding in these areas might entail, it boggles the mind just to consider the sheer waste of so much fresh water. Most of that damaging flood water will be gone forever as it eventually finds its way to the Gulf of Mexico. That’s a shame, because so much of it could be put to good use in the west coast, central, and other parts of the State where it is so desperately needed. The waste is not just limited to damaging flood waters, either. The “top of Florida” is blessed with more rainfall, on average, than it needs. Obviously, the flow of river water into the Gulf represents a volume of water which has not been put to good use.
In passing, we acknowledge that the flow of a certain amount of river water into the Gulf is said to be necessary for the health of the shellfish beds near the coastline.
Even so, it seems inadmissible to stand by and do nothing but watch a surfeit of water in the northern counties lay waste and then go to waste while there is such a great need for water in other areas of the State. Surely there is a partial remedy which might ameliorate the problems in the affected sections.
The Romans found a way to move big volumes of water over considerable distances. Surely we can build on their success – and on successes over the centuries since that time – by constructing an Aqueduct system to bring excess water from the northern Florida counties to drier areas to the south.
The best part is that the right-of-way is already in place! It’s called Interstate 10 and Interstate 75. Take a peek at a map of Florida. Find the intersection of I-10 and I-75. The Suwannee and Withlacoochee Rivers are close by, as are other rivers. There are others to the west, and I-10 probably crosses every one of them.
Excess water could be fed into the Aqueduct lying above-ground or underground in the median of I-10 at various points along its route, and then fed south toward Tampa and St. Petersburg/Clearwater in that part of the Aqueduct lying within the median of I-75 and I-275. Do you see how obvious that is?
If ever there was a perfectly-planned right-of-way for a particular purpose, although not part of the design at the outset, this is it.
There would be hurdles. There always are. Will and determination were invented for the purpose of overcoming hurdles.
It seems to me that the construction and operation of The Florida Aqueduct is an undertaking which private capital should undertake. It need not cost the State a penny.
Let’s see whether anyone steps up to the plate.
