STIRLING ENGINE SOLAR POWER PARABOLIC MIRROR ELECTRIC GENERATOR

GREENPOWERSCIENCE asked:

www.greenpowerscience.com This is a larger Stirling engine that has a 12v DC Permanent Magnet motor operating fixed as the flywheel bearing. It produces 15 Volt max with NO LOAD. This setup as is produces about 15 watts. The heat sink is a water cooled tank that is a bit short for the displacement piston but does work. I will be adding some heat sinks soon and testing it with the 56 inch dish and a Fresnel Lens. The motor/generator has an additional pulley that the other engine I have may be …

Homemade Power
- Best Windmill Plan for your homemade Wind Power
  Do you intend to set up a homemade wind power plant? The most important thing to assure the success of a homemade power system is its plan. Wind power generating system using a windmill is not an exception. The best windmill plan should be including these following features: Guidance documents with illustrations: Visual descriptions with […]
- Homemade windmill – guidelines for windmills set up
  What can we do to cope with world energy crisis today? The first thing we can do right away is to save the existing power with several saving methods. Second, we can try our ways making more power using alternative energy resources. Most popular homemade solutions are wind and solar power systems. Herein after some […]
- What is a wind generator?
  A wind generator is equipment for producing electrical power using wind energy. The machine catches the wind power and conveys it into mechanical energy. This mechanical energy drives the move of the blades (or paddle) in a motor to produce electricity power. Nowadays wind generators contribute thousands of megawatts (MW) of electricity to network. Wind [... […]
- Switch to low carbon solar energy
  The Sun is a gigantic fusion reactor which radiates energy into space. The amount of energy our planet receives in one hour from the Sun is of the same dimension as the world energy consumption in one year. This energy drives the water cycle, causes winds and provides light and heat. The use of these […]
- What is Energy?
  From a little girl’s smile right up to nuclear fusion, energy is the spark of change. For this is issue of ambitions, we turn to a special group of energy experts. We asked children on five continents to answer the question: What is energy? We use energy everyday, sometimes even without noticing. Everything we do […]
- Thermosyphon solar water heater
  The thermosyphon (thermosiphon ormonobloc) solar water heater is one of the simplest, most economical, and, I believe, the best type of solar water heater. It’s a passive system, meaning that it has no mechanical or electrical devices that make it work. Only the sun’s energy is needed to heat the water in the solar collector […]
- What is Solar Energy
  Solar energy is radiant energy that is produced by the sun. Every day the sun radiates, or sends out, an enormous amount of energy. The sun radiates more energy in one second than people have used since the beginning of time! Where does the energy come from that constantly radiates from the sun? It comes […]
- Wind Power – Alternative Renewable Energy
  Energy is essential for life. Since prehistoric times, when man used bonfires to keep warm at night or to cook food, energy has been the force behind human evolution. In its various forms, energy now moves vehicles and even rockets that will take us to new frontiers in space. Paradoxically, the use of fossil fuels […]
- Solar Power
  The use of solar power Solar power has been used in traditional buildings for long time. In recent years, however, it has provoked great interest, as the high cost and limited supply of fossil fuels becomes increasingly problematic in some developed countries. Many businesses and institutions are researching new ways to harness solar power and […]
