How Does a Stirling Engine Work and Its Use in Solar Thermal Technology for Energy Generation
Posted by admin on Jan 20, 2012
Visit – http://www.SolarStirlingPlants.net – A Stirling engine is extremely simple heat exchange engine and works by low temperature difference between two metal surfaces. One surface is heated at one end of the engine while other is cooled down on the other end, causing the air to expand near the hot surface (high temperature) and compress near the cold surface (low temperature). This expansion and compression of air within the engine cylinder enables the movement of displacer or piston in upward and downward motion between the two surfaces into a cycle or loop. This efficient heat engine was invented by Robert Stirling in 1816 as an alternative to steam engines at that time and a great contribution in heat engine technology.
Stirling Engine Basics Explained
An ideal model for understanding the basics of a Stirling engine consists of a closed cylinder containing two metal surfaces (aluminium) at top and bottom of the cylinder. A displacer is placed between the two plates which is connected to a flywheel through a wire to transfer mechanical energy during upward motion. When one plate is heated for example; bottom plate, the air near that plate expands and causing the displacer to move upward. On the other hand flywheel is connected to a small piston which takes the mechanical energy from flywheel and push the displacer to aid in downward motion. When displacer reaches top position the small piston moves downward enabling the compress air to fill in the cylinder and push the displacer downward. Making a loop of upward and downward motion of both displacer and piston, resulting in the circular motion of flywheel.
Use in Solar Thermal Technology
In solar thermal technology we use heat energy from sunlight into mechanical energy to drive a generator or turbine to generate electricity. Stirling engine serves exactly the same purpose and they are very powerful solar power generators and produce clean and free renewable energy. Stirling Engines are used in solar thermal technology within solar dishes where a large parabolic reflector directs the sunlight into one focal point where Stirling engine is placed which then runs by using this heat energy from sunlight and giving mechanical energy to generate electricity. Solar thermal dishes are used in both residential and commercial electricity generation. Stirling engine powered solar dishes for residential use are comparatively smaller in size and generate around 1-2 kW of electricity. Whereas in commercial use a large single engine powered solar dish can generate up to 25kW (kiloWatt) of electricity.
Your geographical location is important in deciding if solar thermal engines are best option for you. Solar thermal engines are best choice for users in areas that get lot of sunlight throughout the year and not so good for areas that get lot of snow and less sunlight.
One of the best way to understand this extremely simple engine is to purchase a small DIY Stirling engine model. For further reading and buying a model please check http://www.SolarStirlingPlant.net History and Basics as well as it’s use in renewable energy.

OUR NEW LEGO LOGIC OFFER
Posted by admin on Jan 18, 2012
Add our solar wheels to your products and this will be the best demonstration to kids from Denmark to Darwin! This tech. pump up gets you massive improvements in the progress of miles per gallon!. The following tells the new story of solar cell photovoltaic’s applications and the science & developing markets that have been overlooked and underdeveloped. We wish to call your attention to “rotating photovoltaic cells, producing power.” Here’s an aerodynamic futuristic design from our engineers:
Try it! Sample it! Test drive it! Burn rubber with it! Spin out with it! Use it on a trial basis- just sample our (pp) wares. We have devised this introduction to high speed rpm rotations of a solar photovoltaic for use on earth and in space. (we have a rotary solar airplane in the works)
Once dismissed as a mere impossibility by all the “experts” the newer versions of photovoltaics in high spinning RPM applications are becoming the dominant force in the understanding and design of working progressive solar power. We have re-invented the in-wheel motor with solar tilting technologies. This “solar pv wheel” could be the tire of the future, with a solar powered propulsion agenda in place of the current hubcap (or spokes, et. al.) (p.p.) Our eco designers are working on a earth friendly “hubcap” with slip ring construction to travel multiple currents thru the car or directly to a motor attached to the wheel hub. (this has a motor attached directly to the solar cell underside, and direct to the wheel.) With “tilting technologies” both the car and wheel are able to seek greater sunlight. pp Our convex cell array will gain the higher angle of incidence to the sun’s light- and they flip up and out, for further volts when vehicles are parked.
Cars can run off of renewable energy and here’s the proof.
We have additional solar wheel inventions that superceede the outputs of the wheels shown. The spin cools down the solar cells array and adds efficiencies. Watch for our solar dome hubcaps to slip onto your car!

Reducing Your Energy Needs before Going Green With simple instructions available on how to convert to homemade wind power or DIY solar panels for as little as $200, many people are taking the alternative energy more seriously. When choosing to take on a DIY conversion project the first question most people ask is will one windmill or one large solar panel be enough? There are too many factors involved here to answer that question for you. But one way to start is to ensure your home is efficient in the first place. In this article we will walk you through some steps that will help you reduce your energy consumption before you start converting your home.
Reducing Your Energy Needs
One often overlooked step in converting a home to green power is reducing your energy needs in the first place. The average home uses inefficient lighting, power hungry appliances, and poor heating/cooling solutions. An important step to reducing your energy needs is to look at the inefficiencies in your current system.
Consider: 1. Replacing old incandescent bulbs with fluorescents or led bulbs will cut your power consumption from light in half.
2. Replacing old, inefficient, appliances may reduce your energy bills by as much as 30% by itself.
You should also look at your current heating/cooling solutions. For example an electric hot water heater could potentially be replaced by a solar water heater. Maybe that inefficient air conditioner can be replaced with a more efficient heat exchanger. If you need help choosing more efficient appliances, an excellent resource for this is put out by the Canadian government: http://oee.nrcan.gc.ca/EnerGuide/home.cfm. It’s called Energuide, and it covers everything power consumption of home appliance to energy requirements of large commercial air conditioners.Spend some time looking through that guide and calculating how much you can reduce your power consumption in different areas of your home. By simply taking a look at everything in your home that consumes energy, you will find ways to reduce your energy needs before you start.You don’t necessarily have to go all out and spend $10,000 replacing everything — but things as simple as changing your lighting will reduce your energy needs before you start your conversion project.
