Bio Ethanol – Alternate Fuel Source

By Anny on November 29th, 2012

Ethanol is pure alcohol which is found in alcoholic beverages. It’s being widely used as a fuel to power automobiles, as an alternative to gasoline and diesel.  Ethanol is generally blended with Gasoline to create a mixture for combustion, as pure ethanol isn’t very combustible in cold weather. Ethanol powered vehicles are being used in Brazil as well as USA and Europe, with the common type being the Flex Fuel vehicles, which can run on a combination of different fuels such as ethanol and gasoline. They are designed to combust any proportion of these fuels, or either of them based on the specific climate requirements. In USA these vehicles are called E85 vehicles and are designed to use 85% ethanol and 15% gasoline due to the ethanol being unsuitable for primary ignition in cold weather. In Brazil, these vehicles are called Flex vehicles and are designed to work on pure ethanol, or any combination of the above fuels.

BioEthanol-Alternate Fuel Source

Bioethanol is the synthesis of ethanol from plant sources such as sugarcane, soya bean, sorghum, corn, maize, sugar beet etc. It involves fermentation of carbohydrates present in sugar or starch based crops into alcohol.  The process involves isolating the sugar from the parent biomass, fermentation of sugars to yield alcohol, distillation of the obtained alcohol, and finally drying the yield to give a usable bioethanol. The residual biomass after the extraction of sugar is widely used to fuel the distillation boilers used in the process. This approach helps in a complete utilization of the biomass, and also reduces the need for an external energy source during the process.

BioEthanol-Alternate Fuel Source

Advantages: Bioethanol is environment friendly, as it emits less carbon monoxide, and the CO2 it emits is again absorbed by plants.  It also has a higher octane rating (The measure of performance of a vehicle fuel) then gasoline, which has a direct impact on engine efficiency and compression ratio. However, it has roughly 30-40% lower energy content when compared to standard gasoline of the same volume, and using it means more frequent fuel stops.

World over,  blended fuels are being used which have a fixed percentage of Ethanol along with standard petrol, such as E10, which is 10% ethanol in a mixture of petrol. This helps the fuel mixture to burn more completely, and reduces toxic emissions.   Ethanol is less toxic and volatile than normal petrol, and is biodegradable.

The primary advantage which we must see in Bioethanol synthesis is the availability of an alternative to fossil fuels.  The world’s crude oil reserves are highly localized, and though seemingly huge- are limited. There should be a smooth transition from our dependence on fossil fuels to other alternate energy sources before we face the realistic threat of depletion of our natural resources.

There also has been a widespread opposition to Bioethanol, as its fast replacing the cultivation of food crops, thereby causing spiraling food prices and food scarcity.  The need of the hour is a proper strategy to encourage such initiatives without compromising on food grain production

THU400X Oil Heater Unit for Biofuel Powered Heaters

By Anny on November 27th, 2012

Home heaters are widely used across the world to regulate room temperature in cold climates.  Instead of using regular fuels to power heating furnaces, biofuels can be used to power a room heater. They are generally powered by blended biofuels, which are synthesized from natural oils, thereby decreasing our dependence on traditional fossil fuels.  These biofuels do not contribute much to greenhouse effect, as the carbon dioxide they emit is again utilized by plants, and are also cost-effective. Also when compared to oil based furnaces, they are less polluting, as they emit less soot and lower amount of toxic gases.

The main disadvantage of using biofuels for furnace heating is that they tend to gel at colder temperatures, which makes the fuel in the heater less combustible as it does not easily move in the unit. Ideally, the fuel must be above the 36-50˚F range to prevent it from gelling. One such solution is using of chemical additives, which tend to lower the rate of gelling. However, they also tend to decrease the energy output, and also emit pollutants while being burned. Instead, you can opt for an external oil heating mechanism, which would regulate the biofuel temperature, and would preheat it in colder weather conditions. An example is the THU400Xoil heater unit, which integrates with your existing furnace, and maintains the temperature of the oil tank to a preset 40˚F.  This would increase the efficiency and usability of your existing heater, and also would omit the need for using chemical additives which reduce your heater efficiency and cause pollution.

THU400X oil heater unit for Biofuel powered heaters

The unit has a built-in immersion fuel sensor which checks the temperature of the oil tank. If the temperature decreases below 40˚ F, the sensor automatically activates the electric heater (400W), which raises the oil temperature in the tank to the required level. The unit is designed to regulate the temperature against going below or above the preset 40˚ F, and the built-in heater would get activated/deactivated as required. The unit requires an electric power source and weighs 8.5 lbs. It measures 6’’ in diameter and 14’’ in height, and can be used between 30-85`F. It can be safely installed to integrate with your existing heating furnace, and you can start saving by using cheaper biofuel alternatives.

Algae- The Next Generation Fuel

By Anny on November 25th, 2012

We have seen how Biofuels made from natural oils are being used an alternative to conventional diesel, largely by blending them with normal fuel. Let’s now look at what algae- the floating slimy green mass you see in seas and other water bodies, can do for us.

During photosynthesis, algae capture carbon dioxide and sunlight and convert them into oxygen and biomass. The Biomass is then processed into biofuel, which can be used as an alternative to conventional fossil fuel.

There has been a lot of research in synthesizing  biofuel from Algae, as a unit of equal  mass  can produce up to 10-100% more oil than other biofuels such as Jatropha, sugarcane etc.  Also, up to 60% of the Algae yield can be converted into fuel, when compared to 2-5% from other plant sources.

A test conducted by Solazyme- a company involved in fuel extraction from Algae, in association with the US navy had powered a container vessel with 100% algae fuel in its voyage from northern Europe to Indonesia, which was a complete success.

Algae can also yield vegetable oil, Methane, and Ethanol apart from the highly viable biofuel

Algae can be cultivated in sea water, as well as normal wastewater ponds, and when it’s harvested, it releases CO₂ into the atmosphere, which again is absorbed by the algae farms, thereby causing no significant increase in co₂ emissions.

 

 
Under controlled conditions, algae can produce up to twice more oil per acre then compared to other fuel crops such as soya bean and Jatropha. It has a very short cultivation period of 1-10 days, which enables much more returns then other fuel crops. It can be grown in marsh waters, seas and also in saline lands, and would not displace other food crop cultivations. However, the yield would decrease while being cultivated in an arid land.

There is an ongoing research to optimize the required resources for such cultivation plants, as they require significant investment. Also, bio researchers are currently looking at isolating certain algae strains which give a comparatively higher yield, and are resistant to common bacteria and harsh climate conditions.

The United States Department of Energy estimates that if algae fuel replaced all the petroleum fuel in the United States, it would require a total cultivation area of just 15,000 square miles which is only 0.42% of the total U.S. land area.

The larger picture which the world now needs to look at is isolating and developing alternate energy sources, and effectively integrating them with energy consumers such as automobiles before the crude oil resources start depleting. Such a research though at an initial stage, has deep rooted practical implications for all of us in the world.

Eco-Friendly Hand Dryer From Mitsubishi GWP Analysis

By Anny on November 23rd, 2012

When we talk about eco-friendly aspects of everything around us, we need to have measurement criteria to judge and decide those actions which are harmful in regards to our environment. Recently in a debate where paper towels of hand dryers were examined as better solution for our environment, a peer reviewed study of hand drying system told that high speed dryers have small impact as compared to any other available dryer.

This study has shown that hand dryers impact on our greenish environment is least and their GWP is also low as compared to other hand drying system. However impact of any item on environment is based on its “use”. Others factors playing minimum role in increasing or decreasing the GWP between 5 to 13 percent.

Although other factors have minimum impact on the system, as long as dry time is similar from a dryer, the impact of such dryers will remain constant based on lower electricity usage and this is least we know.  In 1993 when Mitsubishi introduced the Jet towel, the hand dryers’ benchmark was only 12 seconds then. In this study here we getting reference from, two types of dryers were used for analysis purpose and measured on the based on manufacturing company claimed dry time vs. final testing by Dyson Limited. But Mitsubishi towel as tested By Dyson required only 3.5 watts to dry the hand pair and took 12 seconds and had 20 percent more efficiency over any other dryer.

In order to bring other hand dryers to this level, Global warming potential was set to carbon grams produced and contribution of electrical usage to global warming potential, on the basis on drying time as per Dyson Ltd measured.  Although in this study Mitsubishi Jet dryer was not used, here we have added this for our reference;

  • 100 percent recycled paper towels- 14.7
  • Dyson Aluminum Airblade- 4.44
  • Excel Xierator 7.84
  • Mitsubishi Jet dryer- 2.95
  • Dyson ABS plastic dryer- 4.19
  • Cotton Roll towels- 10.2
  • Virgin Paper towel- 14.6
  • Standard dryer- 17.2

 

When other factors like transportation, packing, production and non-electrical contributions were added in, still Mitsubishi Jet towel had lowest GWP as compared to other dryers. When GWP of other factors was set at 4 to 13 percent and added to these above numbers, it represented as 96 percent or 88 percent of total GWP while Mitsubishi Jet towel value was 96 percent of electricity value.

When GWP was set at fixed level of 13 percent, still Jet towel had lowest level of GWP for its system as found in this study. Although now many other efficient hand dryers are available in the market, still they were compared with Jet towel; its performance was much more than other else. In seven of eight comparisons, Mitsubishi had least GWP value.

This is the reason why Mitsubishi continued to be environmental leader and invented the Jet Towel, told the CEO of Pacarc, James Allard. Mitsubishi has improved both the time and design of jet towel since its first design launching in 1993.

 

 

Environmental Effects of Servers and Data Centers

By Anny on November 21st, 2012

Although a major progress has been seen in Information technology and today it’s the leading source of world. It has changed all the work processes and development flow of IT applications. Information technology itself is not at much green as it looks and all its hardware equipment have been viewed had largest amount of pollution emitters.

 

 Environmental effects of servers and data centers

 

An awareness among the people however have brought a green signal and ready to cope with issues like global warming and effective utilization of remaining resources. Based on our current progress of technology where most of gadgets which we have manufactured and that will perform their role to stop the increasing flow of pollution, it’s time to discuss about impact of our computing system on our environment.

Every person is somehow related to information technology and at least using a single desktop computer if not a laptop or other IT hardware at home. They have spread much then speed of television sets and watches in last decade and an enormous increase in profit of Microsoft, Dell and Intel is revealing the facts that this hardware will increase more in future.  Important to review is how many your computers are contributing to greenhouse effects and leading to polluted atmosphere.

Computing data centers consuming large volume of electricity resources along with increasing carbon footprints and this was the reason that web hosting companies have been warned ad leading carbon emitters than airline industry. The study has shown that currently these companies are involved in large amount of carbon footprints and it’s time to ask for starting the green web-hosting.

 

Environmental effects of servers and data centers

According to this study estimates, airline industry with 2 percent contribution to air pollution is topping the list and first to harm our green atmosphere.  It doesn’t mean that a household PC or a data serving comprised of many thousands of servers are not responsible to be evaluated for carbon footprints and an increasing number of pollution due to data servers.

In small companies offices and even grocery stores, at least two computers are working to store the data, either they are relating to cash registers, sales and other business transactions but not aware about carbon emission from these data computers.

How a single data system you using is evolving the amount of carbon or polluting the environment? If a system is working 8 hours daily and five days a week, total working for 55 weeks in a year, it will use 400 kilowatts power and will omit 180,000 grams of carbon dioxide.  As compared to heaters, Air conditioner or electric irons, an average computer system not as much energy and pollution.

This has been found that refrigerators, furnace and water heater are more carbon offenders. But still there are many ways that can help us to slow the energy consumption from our computers.  All the latest computers are equipped with power management tools so you will be required to kept care of few things to go green with IT.

Always shop smart and count the eco-friendly features of your IT equipments, use the power management tools or reduced consumption mode or hibernation. When your computer has show down, if its plugged it will use little bit of the power, so it is important to unplug your computer form main supply of electricity after shutting it down.

 

CORA Struggle For IPhone Users To Turn Trash Into Treasure

By Anny on November 17th, 2012

A nice idea brought to the forefront when we heard about CORA company new launchings. Recently CORA is working to launch a smart phone application for iPhone users first to connect all the community recyclers. This application will be soon available for all the smart phone users and those eco-friendly guys who want to recycle, donate or make use of old materials by offering local landfill to perform these services.

This CORA trash turned to treasure application for smart phone users will allow users to tell which type of trash they have and how they would like to replace or recycle it and it will also provide them a detail about current recycling DIY projects which will change the trash to treasure. CORA officials told that this smart phones application will allow the users to think two times before they make final decision to throw their trash.

The Kick starter page of CORA is already filled to brim with ideas and those which need to simply the household items. For example if a handful of the used writing pens are donated to the library in your town or change them into funky lamps, or you use the used jeans as hard plastic items in your home for different alternative uses. Also for soundproofing in your cars or as home insulation you can make effective used of old jeans too.  Similar suggestions you will find about plastic mesh bags on CORA forum to reconstruct them into nifty scrubber pots.

 

 

CORA told that it will take only a couple of weeks to raise $70,000 to support this project and invited the people to check out their campaign. You can view the current recycling projects of CORA here.  In this eco-friendly mobile application, a user will be provided with different recycling and reusing options, e. g for a coffee bag a person can select among three options to craft it, cycle it or pass it. Again in craft it option, one can select among three options like make an easy coffee bag purse, coffee bag wallet or coffee bag vase.

If you want to pass this item to recycling units, you will simply click on pass it to trashbags.com website or any other recycling unit. Through social media sharing, once you have installed the application and trying to recycle a product, you can also craft this and share it on social media. How much these struggles form CORA will help to speed up the process of recycling will tell the future but it is predicted that such an efficient clean technology solution will help to clean the environment and make the human beings to understand the process of recycling and keeping it clean with green technology.

Technology is not a big hazard for our environment if this has been understood to focus on reshaping it as green and eco-friendly. Reshaping the technology as eco-friendly will provide long lasting positive effects and a breath for the next generations.

Water Filters for Organic Gardening

By Anny on November 15th, 2012

Water filters for organic gardening

 

Pre-treating your plants with water filters for organic gardening is the most popular trend to make your plants healthy and keep great care of your vegetation.  Most of the organic gardens in town often use the tap water which is supplied to fulfill the vegetation requirements. Until you use rain barrels for collection of large volume of water, you will be required to use the tap water for gardening, but we know that such water is highly chlorinated.

This chlorinated water has been design to kill a certain quantity of bacteria, but some bacteria are required for keeping the soil balance and inner shape. We are just going to start with a new environmental friendly water filter which remove all the chlorine and water and soluble metals from the water, this will ultimately help to grow vegetables and healthy fruits with enriched organic metals required.

 

A filter will work for as long as 25,000 gallons of water and then you will be required to refill it and continue the pure water for our garden. This water filter cost you only $35.50 and you can buy from local stores or online. The Vibrant water filter is best eco-friendly filter available for gardening and those guys who love to customize it according to their needs, they can change its design, capacity and other factors in this water filter.

Water filters for organic gardening

This garden filter can be attached to any garden hose simply and harmful chlorine can be filtered from the water easily. To measure the life of this organic gardening filter, let’s take an idea that water requirement for tomatoes is about 140 gallons in 10 weeks period to get the tomatoes of 20 pounds yield. This GUARDN growing organic water filter will produce enough chlorine filtered water for 1.5 tons yield of tomato crop.

Gardening is amongst our top priority areas to keep our environment green and lessen the effects of pollution and hazardous gases in our atmosphere.  When you use these garden filters for your potted plants, you will stop adding the salt to your pots and water which will be used for plants will lessen the effects of leaves burning.

As for installation of water filters is concerned, they are easy to install and simply screw them to your water bib or your hose.  These water filters will require the back washing if you want to clean them, but they don’t need it.  In these filtering units, they are also replaceable filters, but it is important that you might not change or replace them until they have worked for 20,000 gallons of water, which is approximately equal to one year usage of these water filters.

Gardening filters come in two parts, separated by eight small bolts with Allen wrench. Whey these type of filters? Because they are right priced, eco-friendly and simple to install, efficient at use and do great job, these gardening filters are excellent and you can use them for long time.  This filter is quality product with lifetime warranty.
