Using The Sun’s Energy In A Stirling New Way

 Powered by Max Banner Ads 

During the process of researching an article about green products on photovoltaic cell systems (solar panels), I came across another way to convert the sun’s light into electricity. So let’s take a look at another type of solar energy system.

The Stirling engine goes back to the early 1800’s, when steam was the order of the day. Steam was used to power factories, trains, and many types of work that required lots of horsepower. However, with steam came the danger of a boiler blowing up when something went wrong. Robert Stirling saw a different approach. His invention still used fire to heat the hot chamber but instead of steam, he used the heat to move pistons.

The Stirling engine has many different designs, some more efficient than others. Some designs use the two cylinder Alpha design, some the Beta single cylinder design and some the Gamma design (a variation of the beta for use in multiple cylinder applications). The beta Sterling design has a single chamber with two pistons and uses a highly efficient regenerator gas as the thermal conductor.

To operate the Stirling engine only an external heat source is required, which could be anything from solar heat to the heat produced by decaying plants. In one model, the heat from a human hand powers a small version of the Stirling engine!

The basic operation of this thermal engine is really quite simple. The engine has two chambers, one hot and one cold. When an external heat source is applied the hot air expands moving a piston and flows to the cold chamber. A flywheel is attached to maintain movement.

The Stirling engine is ideal for use in a solar power generating system. With one of the hottest heat sources available (sunlight), the hot chamber will continue to operate without external fuels as long as there is daylight. This makes it ideal for use as a peaker type power plant when the demands for electricity are at there highest.

With better-designed engines and new types of material, a movable (tracking) parabolic mirror, and a single Stirling engine you can produce 25 kilowatts of electricity.

In a future article about green products I will list the different solar technologies and how they compare to the competition.

Converting The Sun’s Heat Into Electricity

In the process of doing research for an article I did on solar green products, I came across the Stirling air engine. The engine was once called a hot air engine because it requires no internal diesel or fuel to run. Let’s take a deeper look at this unique engine that requires no fuel and has recently been adapted for use on solar collector dishes.

The Stirling engine goes back to the early 1800’s, when steam was the order of the day. Steam was used to power factories, trains, and many types of work that required lots of horsepower. However, with steam came the danger of a boiler blowing up when something went wrong. Robert Stirling saw a different approach. His invention still used fire to heat the hot chamber but instead of steam, he used the heat to move pistons.

The Stirling engine has many different designs, some more efficient than others. Some designs use the two cylinder Alpha design, some the Beta single cylinder design and some the Gamma design (a variation of the beta for use in multiple cylinder applications). The beta Sterling design has a single chamber with two pistons and uses a highly efficient regenerator gas as the thermal conductor.

To operate the Stirling engine only an external heat source is required, which could be anything from solar heat to the heat produced by decaying plants. In one model, the heat from a human hand powers a small version of the Stirling engine!

The basic operation of this thermal engine is really quite simple. The engine has two chambers, one hot and one cold. When an external heat source is applied the hot air expands moving a piston and flows to the cold chamber. A flywheel is attached to maintain movement.

The system is ideal when a concentrated heat source is applied, in this case sunlight. The sunlight is collected with parabolic mirrors and focused on to the surface of the hot chamber, causing the chamber to be heated and the engine to start. This temperatures can be very high. You know this from, when as a child, you took a magnifying glass and focused it on a piece of paper. When done correctly the paper would get dark and then a flame would appear.

The engine and support equipment is contained in a package small enough to be suspended from the end of a metal arm, much like the design of satellite TV systems but on a much larger scale. Some systems are producing 25K watts of power and have been installed and operational for a couple of years.

In a future article about green products I will list the different solar technologies and how they compare to the competition.

Getting To Know Carbon Footprint

The name Carbon Footprint is normally used for the influence which the activities of the human beings have on the atmosphere.

The Carbon Footprint fundamentally relates to our activities and the green house gases that are released owing to our daily activities. These gases at last supply towards boosting the greenhouse effect, and consequently the environment of not only a region but the total earth is affected and the health and survival of the earth is put at hazard.

Some of the activities that have the direct and most significant effect by the release of greenhouse gases are the burning of fossil fuel for energy consumption, electricity and various electrical appliance, transport, and also heating.

The Carbon footprint fundamentally constitutes two parts, i.e, the primary footprint and the secondary footprint. The primary footprint is the estimate that is used for activities that release direct carbon dioxide. These activities chiefly consist of burning of fuels, or transportation etc. The fuels are burned in our every day lives for the purposes of household and industrial power utilisation.

Alternatively, the secondary footprint is the estimate for an entire lifecycle. This denotes that somewhere in the construct of these products, there is the discharge of carbon dioxide owing to a final breakdown. This denotes that the production of these products has a direct influence on the atmosphere. The more we procure and devour such products, the more is the demand for their production, and at last there are more dangerous emissions in the atmosphere.

There are several online carbon footprint calculators accessible. Carbon footprint calculator is fundamentally a device which gives you a clear idea about the effect you are making on the atmosphere with your lifestyle. This is possible to estimate because each activity has certain importance in terms of the carbon footprint, and weights are assigned to your activities and in the end you are able to know the effect that is generated in the atmosphere on behalf of your everyday life.

As the people of this world, it is significant for all of us to keep in mind the idea of the Carbon footprint and take essential steps to decrease the unconstructive impact of our activities on the globe. There are a lot of different steps that can be taken and efforts that can be made on the individual level to bring about a constructive effect on the future of our world.

Electrical appliances such as computer, TV, DVD player, etc ought to be turned off when they are not being used. The water heating as well as the central heating ought to be turned down whenever you think that you don’t need it. If likely, you ought to keep away from using the clothes dryer. These are a few of the numerous things that you can take to develop the Carbon Footprint.

All about Micro-CHP

Among several power applications, power is required in many forms. These power forms characteristically comprise of some arrangement of heating, ventilation, air conditioning, mechanical power, and electric power. Most of the times, these additional kinds of power are marked by a heat engine working on a foundation of high-temperature heat.

A heat engine cannot have best efficacy in relation to the second law of thermodynamics; therefore a heat engine will always create a redundant low-temperature heat. This is mostly referred to as “waste heat” or “secondary heat”, or “substandard heat”. This heat is essential for the mainstream of heating applications, nonetheless, it is usually not measured realistic to relocate heat force over protracted distances, dissimilar to electricity or fuel force.

To make proficient use of energy, the “waste heat” must be used tenaciously. Since it is convenient to transport electricity but unfeasible to transfer waste heat, an energy proficient system have to produce electricity only at places where the waste heat can be put to superior use. One method to craft improved use of the “waste heat” is to get through the main energy source on-site, and accordingly produce energy in all of the requisite forms, at the place of use. This is recognised as a combined heat and power (CHP) system, or “cogeneration”.

CHP systems are capable of perking up the entire force employment of main force sources including fuel and intense solar thermal force. Thus, CHP has been gradually attaining appreciation in all segments of the force economy due to the augmented prices of fuels, primarily oil-based fuels, and due to ecological concerns, principally environment change.

Micro-CHP systems’ major difference from their larger-scale family is in the operating limitation driven procedure. In quite a few cases, industrial CHP systems chiefly make electricity, and heat is a precious consequence.

Tenaciously, micro-CHP systems which function in residences or small business buildings are driven by heat-demand, distributing electricity as an upshot. Because of this working model and because of the erratic electrical demand of the arrangements they would be apt to function in homes and small business buildings. Micro-CHP systems often create more electricity than is unswervingly being asked for.

In today’s time, due to its effectiveness in savings, micro-CHP systems have gathered great response from the consumers. Its key function is “produce-and-resell” model, According to which the power in excess from the required, is allowed to resell or is sold back to the electrical utility. This system is proficient because the energy used is dispersed and used immediately over the electrical grid.

The main losses are in the conduction from the foundation to the client, which will obviously not equal the losses sustained by storing power locally. If the fraction of homes with electricity producing systems is big, then the result on the network may become significant. Harmonisation amongst the generating systems in homes and the network is necessary for unfailing procedure and avoiding damage to the network. Consequently, from a solely scientific point of view, net-metering is very dexterous.

Yes! Generating power In Your Own Home is Possible

Generating energy in your home may sound like an exclusive and technological choice, but there are people who are looking at alternate energy sources to cut down on using straight electricity. We utilise electricity for lighting, heating, and for running appliances. We require seeing, what alternate energy sources can be used to generate power in your home.

The sun provides us with radiance and warmth, and this radiance and warmth can be used to create power for lighting and running appliances. Solar panels are used to use the sun’s power to create electricity. The solar panels have photovoltaic cells that charge batteries. The power from the batteries is used for lighting and running appliances.

Using solar panels has now become a universal system of generating power for the plan of using in homes. The photovoltaic cells create power when the sun shines on them. The more sunlight, the more power is generated. Solar panels don’t require intense sunlight to run, they develop the daylight. Solar panels can be installed on roof tops.

The second natural supply that can be used for generating power is air flow. In areas such as sea side where there is a stable current of air; air flow turbines can be installed. Depending on the size of the breeze turbine and its potential, a large amount of electricity can be produced. The wind turns the propeller which in turn rotates a generator that generates electricity.

In some countries like Holland, wind turbines are used to generate electricity which is supplied to the country. If you happen to live in a place where there is a constant wind blowing, using the wind power to generate electricity is a cheap option. It only costs installing of the wind turbine and generator to generate electricity. The wind, like the solar power is free.

Another alternate resource for generating electricity is burning biomass. Rural waste and animal waste are made into pellets and burnt in a heater. Likewise, water is heated which converts into steam and is used to turn a power generating turbine. Biomass can be used to produce power on a farm. It’s not realistic to believe of installing a biomass driven generator in cities.

For heating the house during winters, another alternate equipment is using geothermal. The soil present a few meters down maintains a temperature of 11-12 C in UK. By passing a coil through the earth, the innate warmth of the earth can be used to warm homes.

These are some of the ways in which we can save power by generating power in our homes. Installing and using these alternate power sources depends on the space available. They do not charge much, and in fact, requires just a onetime investment. Once you create your own power, you can cut down on the electricity that you may otherwise use from the public utility board. Also, all these energy sources are known as green and clean sources of generating electricity. So, you may be helping the ambiance by using a natural source of energy to create electricity.

Ways To Reduce Your Carbon Footprint

Global warming is a fact. Many people find it very easy to disregard, but on the other hand a large number of people are in fact taking notice and trying to do what they can to decrease its unhelpful impact on the situation. It’s actually easy to make simple changes to the way you live so as to decrease your carbon footprint.

Begin by localising your purchases. If you procure things that were produced close to where you dwell (your city or country) then you are aptly reducing the amount of things that have to be brought in from further distances. Another thing that can be done is to purchase organic products. By using pure products, you can lessen the amount of deleterious chemicals that are used.

When you go shopping, take your own cloth or plastic shopping bag with you. Plastic is better than paper, and cloth is better than plastic. By taking something from home, you can reduce wastage and saving the environment. In addition, when buying products, look at their packaging and opt for products that do not have wasteful packaging with them, for example, instead of buying individually plastic wrapped vegetables, buy them loose and unpacked.

Stop drinking bottled water. The bottles are manufactured in one place, and then shipped to some other place where bottling is done and is then dispersed. Make it a point to take your own refillable water bottle with you, and refill it from home or office water dispensers. If easily handy, prefer to find filtered water with your meal instead of bottled water.

Go through your home with a technician and make certain you aren’t leaking power. Look for cracks in and about window and doorframes. When you’re not at home, turn the heating or cooling off, or have it on a time-specific thermostat. Use glowing lights as an alternative of luminous ones as they use 75% less power and last longer.

When buying plants for your house, buy ones that grow in the natural environment in your city or country instead of buying exotic plants that are shipped in from farther away. Also, opt to use local and organic soil when gardening.

If you require travelling, attempt to travel via bus or train as they use less power and fuel. If you cannot travel by bus or train, use air, but be assured that you attempt and take a non-stop flight instead of one with a lot of links.

When you are gone on holidays, make certain you unplug all appliances at home so that they do not use power. These embrace televisions, mobile chargers, kitchen appliances, and any other thing that is plugged in to a power outlet. Even when they are on standby, they use a small amount of power, which can mount up a lot over time. Also, put your water heater on sleep mode so that it warms, but does not warm through your water supply while you are away.

When doing the laundry, prefer to employ the lowest warmth you can for the wash. Same goes for the dishwasher and your showers. It takes a lot of power to heat up water.

Ways to Reduce Your Energy Bill

With costs rising and uncertainty about the economy plaguing everyone, it is important to manage successfully from wherever possible. One of the easiest places to reduce expenses is in your house. By ensuring that you are not wasting money on water, electricity, heating, or unnecessary groceries, you can save tons of money every month.

One of the easiest things to cut down expenses on is electricity. Cutting your energy bill is going to save you thousands of pounds every year. Here are some things you can do in this regard:

- Inspection: Get a technician to examine your ventilation, heating, and air-conditioning to make sure it is operating efficiently. Sometimes a simple filter replacement is all that is needed to reduce consumption.

- Energy Star Guidelines: When buying air conditioners, look at Energy Star Guidelines to make certain you are getting one that is appropriate for your requirements. Getting one that is excessively big will only cost you more, and therefore take more energy to function.

- Cleaning: By ascertaining that your gear is kept clean and has appropriate upholding regularly, you can save money. Remember to clean the air filters on your air conditioner monthly.

- Thermostat programming: you can shun needless utilisation and save some finances by adjusting your thermostat setting with timer so that your air conditioning or heating shuts down when you are at employment.

- Seal your home: You can save on heating and cooling overheads by ascertaining that your dwelling is appropriately sealed and hot or cooled air is not leaking through small spaces within doors and windows.

- Light bulbs: Make certain you employ glowing bulbs because they can save you 25% on power, and even make less heat.

- Close the blinds: Keeping your window blinds down in the hot season will lessen the heat that enters your dwelling.

- Fans: Using fans can decrease the temperature by some degrees. Just remember to switch them off when you aren’t in the room because fans don’t cool the home, rather they just make you feel cooler when you are below them.

- Unplug gadgets: Make certain your microwave, cell phone charger, and other power consuming appliances are not plugged in when not being employed. The major waste of electricity is when people leave these appliances plugged in – even when on standby – because they employ electricity and make heat in that condition also.

- Energy Providers: You can also look for various energy providers in your area to see if you can choose cheapest possible. Some energy providers allow customers to choose a plan that costs them less rates for off-peak usage. Finally, you can pay a flat rate per kilowatt used every month. Make sure you talk to your energy provider about the options available to you.

By following these tips, you can decrease your energy use in no time, and can therefore decrease the amount you spend on power each month. Also, you are also helping the environment by using fewer resources.
