Is Making Biodiesel at Home Safe
The flammability point of biodiesel.
I’ve mentioned that it’s biodegradable that it’s safe to use blah, blah, blah, all these different things, but I want to show you how safe this is. This biodiesel, I’ve made from canola oil, so I’m going to pour a little bit in here, and now it’s time to play with fire. We’re going to come down here. Light up our torch, notice I have my fire extinguisher people.
We now have a nice blow torch going. Notice I’ve got some nice biodiesel on the ground here. I want to show you that biodiesel is very, very safe to have around. I can’t light it on fire. This torch is a really hot torch. I’m actually using map gas. Map gas actually has a higher flame temperature. So I’m just trying to light this sucker on fire, and you know what, she’s not going. That’s because biodiesel isn’t actually that flammable. It has a much higher flash point than normal diesel, and I’ve just proven it.
And that’s one of the reasons people like biodiesel is because it’s so safe to use. In fact, if this stuff spills on the ground the MSDS and things that it calls for is get a garden hose and wash it off. It’s not going to light up. It’s as safe to have around as vegetable oil. No I have to cavy up that this biodiesel has been cleaned. We have got all the methanol out of it, and we’ll talk a little bit about that later, but I just want to show you that it’s very clean and it just doesn’t burn. That’s that little fun experiment. We want to show you that biodiesel will burn though. When it’s under pressure it does burn quite well. For this experiment I’m just going to start a fire, and I’m going to spray it into it. As you can see it will burn, so when it’s in your diesel and it becomes injected, it will burn beautifully. That’s biodiesel burning.

Recycling Helps Prevent Global Warming
If you want to keep the environment clean then you need to recycle everything you can. You should set aside a few spaces so that you can keep your recyclables in a separate area. All of your water bottles should go into one container so that it will make it easier for you to take them to the recycling center. Also you need to make sure that you recycle all of your chance and glass bottles as well because this will also help the environment. Many people do not know that you can also recycle your old newspaper, you can call to have it picked up each month.
If we are going to prevent global warming than one way that you can take part is to recycle everything you use. the best thing you can do is educate yourself on the best way that you can recycle all of your throwaway items. Maybe some of your old clothes can be donated to Goodwill this way they can be recycled and used again. Make sure that you try to avoid using plastic bags from the grocery store because once they end up in a landfill they can cause a lot of problems. Once you have started a recycle program in your house you will find that it is easy to do.
Remember that if you want to improve the environment you need to recycle everything you can. It always works better if you have specific containers that you use for each of your recyclable items. Once you make a few small steps towards improving the environment you will feel better about yourself.

Plasma Gasification Plant Benefits For Municipal Waste Management
Plasma Gasification Plant (PGP) projects are being developed by at least five gas plasma technology companies, and there are real benefits to be obtained from this technology for the destruction of Municipal Solid Waste (MSW).
There is some debate still whether the process has been demonstrated to be a vaible technology which can be reliably operated by our waste management companies at reasonable cost and in compliance with all emissions regulations. However, the consensus seems to be largely in acceptance now that the technology is largely proven and inherently cleaner than incineration.
Although, gasification is used as a power generating technology, and gas plasma plants do provide a power feed-in to the local power grid, it should be realised by all that the purpose of selecting plasma gasification is currently that of achieving maximum waste mass destruction. The intent of the PGP is primarily to provide an efficent and clean method of dispoing of large quantities of residual MSW. Plasma gasification, although it does produce energy from waste is not primarliy an Energy from Waste (EfW) or Waste to Energy technology. There are other better proven, more efficient, and potentially always also cheaper ways to produce Energy from Waste, such as incineration.
PGPs suffer a high sacrificial load from the use of power at the electrodes to generate the plasma, and energy is also expended before the MSW reaches the plasma zone in the gasifier in chopping up and ensuring that the particle size of the waste is quite small. For this reason they do expend a large proportion of the power generated just in maintaining their own internal power demand.
However, as a waste destruction method producing an inert residue without creating at the same time high levels of toxic gaseous emissions the gas plasma process excels according to reports made to date. It has every reason to be cleaner as well because the reactions which take place in the plasma state take place so quickly and completely that the toxic organic chemicals produced in other combustion processes simply don’t get a change to be produced.
For a waste management process PGP therefore holds a very good prospect of adoption, as it is a process which is very efficient at diverting waste away from landfill, and thus scores highly among local authority waste disposal engineers who are constantly seeking to comply with regulations to reduce the amount of organic waste sent to landfill.
The PGP process however, also holds another merit and that is that it is being viewed more favourably by the public than incineration, and one main reason for that would be its clean emissions record when compared with incinerators historically.
Throughout Europe the requirement for BMW to be reduced by ever larger percentages necessitates the use of new technology to achieve this high rate of waste diversion, even after high recycling has also been achieved.
Look out for a plasma gasification plant appearing in a district near you soon, and look favourably upon it!
Steve has built a great web site where there are a lot more facts about gasification. This is a hot subject indeed for this technology which has become an essential read for all those who appreciate renewable energy issues and are interested in taking action to reduce the impact of climate change.Article Source: http://EzineArticles.com/?expert=Steve_D_Evans

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: 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 diversion of water out of the river removes water for healthy in-stream ecosystems: 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.

Analysis of Cleanliness
You cannot control that which you do not measure.
In more and more industries, the exact knowledge of particle contamination is gaining in importance. Contamination of materials in dimensions of a few micrometers was mainly of concern for the pharmaceutical and semiconductor industries. However, not only manufacturers of circuit board components, but also traditional car parts suppliers face new demands on particle recognition and contamination source identification.
Cleanliness for the automotive parts manufacturers has become a huge topic in today’s ever challenging continuous improvement world. The need to define, measure and control the levels of particulate contamination on product is the new norm for suppliers and automotive OEM’s.
Cleanliness directly relates to product warranties, reliability, performance and safety issues. It has long been known that a dirty product gives us poor quality and low life expectancy. The dirtier the transmission from new, the less time it will last.
It is crucial now to identify particles and their source so that effective elimination can be achieved. Residual contamination consists of particles that persist on the component’s surface after the final step in manufacturing. Such contaminants are introduced via parts from suppliers or arise during processing. After vehicle assembly, the contaminant particles can cause severe damage, loss of function or reduce the lifetime of the product.
Cleanliness is defined as the contamination level of a component surface. Common measures to quantify the cleanliness are mass of the contaminants as well as number, size of the dirt particles. In general, the customer will specify contamination limits. The supplier then has to maintain these levels and document them regularly by means of contamination analysis.
The analysis of the contamination has to be proven to not affect the result and to be effective in evaluating all the contamination present. Methods of extraction and evaluation are specified in the international standard ISO 16232. Particular attention must be paid to the extraction method to ensure no contributing factors are introduced to the evaluation. There are different methods of counting the resulting extracted particles but by far the most accurate, repeatable and cost effective is automated microscope analysis. The microscope with software can scan the filter membrane; sort the particles by size class and even determine basic material composition (metal, non-metal, fiber). Once the data is gathered a custom report can be generated based on the customer requirements.

Water Efficiency – The Resource Matrix Part 1 of 4 – Why We Have Water and Fuel Shortages
“The Resource Matrix is everywhere, it is all around us. It is the world that has been pulled over your eyes to blind you from the truth. You take the blue pill and the story ends. You wake in your bed and believe whatever you want to believe. You take the red pill and you stay in Wonderland and I show you how deep the rabbit-hole goes.”
In my last water efficiency article (Water-Efficiency: Why Most Advice You’ve Read is Absolutely Inefficient), we began a slow turn away from lighting with a discussion of the 80/20 Rule and how your little positive behavioral changes with water aren’t even a drop in the bucket when your other positive behavioral changes – making homemade pizza – evaporate the entire year’s ocean of benefits in a few tasty bites.
In a four-part series, we talk about a resource besides energy: water.
- Today, we begin far above this “turn off the porch lights and take short, icy showers” efficiency thing to show you how we got to where we are now both in fuels and in other resources.
- Next week, we introduce the resource called water, its parallels with fossil fuels, and its role in global warming.
- The following week, we continue going with the flow of water, when we show the parallel between the current hot Oil Wars and in the future cold Water Wars.
- And in the final week, we tie together the articles in a symphony of three movements, showing you how all the elements hold the Resource Matrix in place and how, like Neo in the movie, you can break the code that creates the graphical user interface and see the illusion for what it really is. (At least, my version of it, anyway.)
Ready to take the red pill and see how deep the rabbit-hole goes?
We start with one of the most boring subjects known to college students, one birthed out of the Enlightenment when extremely titled, idly rich, powdery wig-headed fancy foppish men dressed like women and walked in high heels and squealed like school girls:
Economics: it’s totally insane
Economics is described as the science of allocating scarce resources. Since it’s the study of human behavior, it’s a social science rather than a physical science.
And although any individual’s behavior may not be predictable, individuals as a group can be. Kinda like the weather: you don’t know much about a single raindrop’s effect but you can track the overall storm and predict what’s next.
Economics likes to fool itself that it can predict behavior based on the assumption that people make rational choices. Understand what people think and you understand what choices people will make.
It unfortunately leaves out the other part of being human: human behavior based on emotions.
And emotions weigh heavily in how we interact with each other, especially in exchanges of value.
Maximizing returns:
“I want your goodies for nothing”
Economics recognizes that people are motivated by self-interest to maximize their benefits at the lowest cost.
On an individual basis, this can turn into a “win-lose” proposition:
- I want to acquire the best stuff for the cheapest terms
- I want to dispose of the lousiest stuff for the greatest terms
In short, you want diamonds and gold for nothing and they want to give you useless junk for a king’s ransom.
May the Force be with you:
getting diamonds and gold for nothing:
Economics comes out of 18th century political economy, which studied production, buying and selling, and their relations with law, custom, and government. Political economy itself comes out of moral philosophy.
This moral philosophy apparently had room for colonialism, which comes pretty close to getting your diamonds and gold for nothing: forcibly take over a country and use its people to extract its resources to be reallocated to your bank account. And make sure nobody but you has any say in the matter.
Social good in the equation:
A few people didn’t see the morality in this philosophy. Enter the lousy, meddling individual do-gooders like Elizabeth Cady Stanton, Mohandas Ghandi, Martin Luther King, Jr., Upton Sinclair, and many others who messed with the “I want your goodies for nothing” crowd.
And some of the individuals do-gooders formed their own organizations like the Sierra Club and Greenpeace.
They all worked to increase awareness that there are alternatives to being forced to give away your diamonds and gold for nothing while having no say in the matter, and worked to change deals from “win-lose” to “win-win.”
The “I want your goodies for nothing” crowd, who could only lose in the change to “win-win,” found their salvation in the late 1800s with the rise of modern psychology (the scientific study of mental functions and behavior). Applied to politics, it’s called propaganda. Applied to spirituality, it’s called religion. Applied to commerce, it’s called marketing and advertising.
All these applications are forms of hypnotism, and are based on the proven principle that if you repeat anything enough times, including a falsehood, your audience will grow to believe it and then to defend it as the truth.
The “I want your goodies for nothing” crowd used economics to hypnotically declare for 250 years that fossil fuels, the air, and water were without cost. They called them “free goods.”
And they used force (”Oh yeah, and what the hell are you going to do about it?”) to declare that pollution had no consequences.
What’s an Oxymoron?
“Free Good” in economics
The free good is a term used in economics to describe a good that is not scarce. A free good is available in as great a quantity as desired with zero opportunity cost to society.
Earlier schools of economic thought proposed that free goods were resources that are so abundant in nature that there is enough for everyone to have as much as they want. Examples in textbooks (even in the 1980s) included fresh water and the air that we breathe. However, these are now regarded as common goods because competition for them is rivalrous.
In short, there is no free lunch.
An additional moral philosophy:
“There’s a sucker born every minute”
becomes
“How can I help you help me?”
The “I want your goodies for nothing” crowd continues to rise early and work late to craft their “win-lose” deals every day.
Yet, out of those rising early and working late, a small radical fringe discovered the curious fact that if you don’t beat a dog bloody every time you see it, it’s less likely to bite your hand off, and it even might go out and hunt down a squirrel for your evening stew.
Their moral philosophy became a hybrid offshoot.
The Hybrids still want your goodies, but they are willing to help you get your goodies with less pain and damage to yourself so you’ll be willing to come back to them and hand over more of your goodies.
Both use the same mind-numbing hypnotic slogans: “We care about you.”
The difference is the Hybrids actually do some of those same things that someone who cares about you would do. Even if they don’t actually give a hoot about you. Contrast that to the “I want your goodies for nothing” crowd, who merely sends you more hynoptic slogans when they want your goodies.
Where Do You Want to Go Today?
Everywhere but here
We’ve all awaken to the shocking realizations that:
- finite energy resources will run out
- actions have consequences, and the consequences of our actions are already visible, rather scary, and quite irreversible, and
- the “I want your goodies for nothing” crowd hasn’t been telling the truth
In Aldous Huxley’s Brave New World, you could just pop some soma and totally trip out.
But the cowardly old world we’re experiencing has quickly turned into a total bummer of a bad trip, man. Down with the Establishment and praise the Collective.
We’re all in this together, or
Toss the lousy, greedy bastards overboard
The decades of the Do-Gooders increasing our awareness of possible “win-win” possibilities and of the Hybrids backing their “we care about you” lip service with actual service has brought us to another realization:
There’s a price to everything, and if I don’t pay the price, someone else will, and somehow, some way, on some sunny day, they’re going to get even and make me pay.
And this has been an important change in the understanding of energy efficiency and global warming: the environment has a limited capacity within our human-lifetime periods to absorb civilization’s byproducts and transform them into resources. It usually needs geologic time to turn dead trees and critters into oil and gas. In the meantime, the trash piles up in the streets.
The solution: create less trash.
Thanks to the Do-Gooders, we have greater awareness or our actions and the desire to change, and have the Hybrids offering ways to change.
And the result is a shift of power away from the “I want your goodies for nothing” crowd. It’s now Power to the People.
But wait, there’s more …
to the Resource Matrix
Just because you know about fossil fuels, their finite amounts, their polluting, warming effects on the environment, and alternatives offered by the Hybrids – even if you have done your part to the best of your ability to reduce, reuse, and recycle — you haven’t escaped the Resource Matrix.
Energy to power our lives is one component of the Resource Matrix. And it’s the most visible in discussions of global warming and being resourceful. But there’s more:
Coming Attractions!
In the next three articles, we will talk about concepts concerning the resource that makes up 75% of the planet and 75% of your body:
Water.
You’ll learn that, although 75% of the planet is water, only 3% of water is potable (can be consumed), and of that 3%, only a small fraction is available, and of that small fraction, only a small fraction is potable, because the rest is polluted for hundreds of years to come.
You’ll learn how the actions of an illiterate, lice-infested, foul-mouthed peasant on the other side of the globe affects you where you are.
You’ll learn how, unlike oil, water is transferred invisibly from poor to rich by sleight of hand, like paying your utility bill through your online bank account.
You’ll learn how poor water decisions, rather than fossil fuel’s atmospheric effects described in Al Gore’s An Inconvenient Truth, leads to those drybeds of the formerly humongous Aral Sea and along the Amazon.
You’ll learn how to measure the global water impact of any nation, city, corporation, even yourself – to the nearest gallon or liter.
You’ll learn the little changes you can make – the water equivalent of “change your incandescent lightbulbs to compact fluorescent lamps” – and still be able to take your wastefully long showers.
And all of this is for one purpose:
To help you see the Resource Matrix, everywhere, all around you.
And now I would like to offer you free access to powerful info on energy efficiency that’s easy to read and cuts through all this “green” information clutter — so you can literally start making positive changes today.

Cheap Flights and Climate Change – Do We Want Too Much?
What can be done about this increasingly worrying contribution to global warming?
The most important options to reduce aircraft CO2 emissions are:
Changes in aircraft and engine technology; use of alternative fuels, such as (sustainably produced) biofuels; regulatory and operational measures such as improvements in air traffic management; economic measures such as inclusion of aircraft emissions in emission trading schemes.
But, as Giovanni Bisignani, manager of International Air Transport Association (IATA), stated: “Emissions trading schemes only make sense with efficient infrastructure. The IPCC estimates that there is 12% inefficiency in air traffic management globally: we produce up to 73 million tonnes of carbon emissions each year by aircraft flying inefficiently due to air traffic management limitations”. **
On a personal level we could ask ourselves especially in the developed world: “Do we really need to fly so frequently?” The use of telework, teleconference and video conference could be largely increased to plan work and meetings. Can’t the development of land and air transportation infrastructures be balanced better according to the real needs of people and businesses? Trains could connect cities better and more cheaply for example in Europe, where the prices are not competitive with those of many flights anymore (and night train services have been reduced if not cancelled).
Life styles do matter because if millions of people want to have cheap weekends in relatively close tourist locations, many flights are needed to satisfy their desires and consequently a lot of pollution is generated. Also, our per capita emissions could be cut also by reducing the “surplus” trips, by slowing down our life rhythms and enjoying more local attractions in our free time. Who knows? We could discover the “exotic” in our own neighborhoods without flying to the Caribbean Sea…
Furthermore the relationship between the costs and the environmental externalities (i.e. costs not included in the economy like health damages caused by pollution) needs to be considered as well: there are higher marginal impacts for short-distance flights that should be considered in prices paid by passengers.
All these political, technological and personal choices are some of the good examples needed by the developing countries to follow the 21st century’s Western society along a new sustainable path which looks like the only good alternative forward.

We’re in this environmental mess because humans have exploited the earth for personal gain. However, you can sell your laptops, get some grocery money and still help the planet. Steer clear of the attitude that everything is disposable after a few uses; do your part and extract the most out of your electronics. In carelessly tossing away our possessions, we are the reason that one more thing spends an eternity in a landfill. Electronics, including laptops, are one of the most significant sources of toxic heavy metals, including cadmium, lead and mercury, leaking into the soil, according to the Environmental Protection Agency. Pollutants do no simply stay within the confines of the landfills, but are transported through waterways and through the air. When toxic metals travel upward during evaporation, these toxins contribute to acid rain, spreading the heavy metals for miles. Dr. Lorris G. Cockerham, former professor at University of Arkansas and researcher, wrote that build up of toxic heavy metals in animals damages their vital functions and hinders growth in plants, therefore irrevocably harms ecosystems. The heavy metals seep into waterways and into our water sources. These heavy metals can enter our body through the ingestion of contaminated water, harming our bodies. Even a low concentration can harm us, according to James Girard, author and professor at the American University. A solution? Sell your laptops to a recycler. When you sell your laptops, the laptop parts find new life with computer repair shops and wholesalers, avoiding certain doom in a landfill. Selling laptops is an easy process for the average time-constrained American worker. Search for “sell laptops” on the Internet. Locate a recycling company who will accept the laptops you are selling. Lastly, look for the V logo that signifies the company is verified organization, not a Nigerian scam. Many business will offer an instant quote on their Web site for the laptop you are selling. Input the specifications of your laptop, follow directions and you have check or a PayPal payment for your laptops. Make sure you choose a reputable company to sell your laptops to. Some companies boast a “green” philosophy, but actually ship laptops to landfills in developing countries. We all have a part in this green earth and many of us have take steps to follow the mantra, “reduce, reuse and recycle.” Many people think about selling their cans, bottles and such and don’t think about their computers. Do your part, keep our Earth Green and sell your laptop. Katy Marie is a freelance writer located in Reno, NV, who wants to keep the Earth beautiful. To find out more visit Cash For Laptops

Actually, there is a better way by which we can save up on fuel without having to let go of other necessities or luxuries that we have in our life. Sometimes we need all this to keep us going. When you take away one or two, you may take away your only source of happiness. So think twice before cutting off hobbies or things that you are already accustomed to. One thing by which we can save gas is if we make it ourselves. It is possible since homemade biodiesel kits are available for consumers to buy them. There are instructions online and there are even step-by-step videos on how to make biodiesel fuel. These are especially useful for people who prefer to see it than reading about it. The great thing about seeing how it is made is you can actually see the equipments that are being used. So you can always pattern your equipment with what is being shown. Since you will be doing it yourself, there are a couple of things you have to watch out for. You have to watch out for methanol and lye because it is dangerous. Aside from that, since you will be making use of heat and vegetable oils, fire is always a possibility. First time makers of biodiesel fuel should be extra careful when proceeding and like any other endeavor it takes practice to perfect it.

How it Will Benefit Us All: Gasification
If you search for gasification and terms like “wood stove†on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.
So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?
What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.
This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.
Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.
Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.
These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.
Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.
Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.
Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.
Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.
Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.
