IBM’s Photovoltaic Prototype Can Concentrate the Power of 2000 Suns

Posted by Leigh Kim in Solar Power, Stirling engine on April 22, 2013

IBM Researchers have built a low-cost prototype solar dish that produces electricity and generates heat for desalination or cooling. IBM got the idea for the solar dish from the water cooling technology used in its high-end computers. The Swiss Commission for Technology and Innovation has provided $2.4 million worth of funding to IBM, Swiss researchers, [...]

Solar Powered Stirling Engine Technology Breaks Efficiency Records

Posted by Mila Luleva in Solar Power, Stirling engine on January 18, 2013

Ripasso Energy, a solar technology company based in Sweden, has designed a Solar stirling dish modules that set a new efficiency world record of 32%. The dish modules convert sunlight in most climates, however they have proven to be most effective in hot and dry climates, where the system converts one third of the solar [...]

Thingiverse Raves About 3D Printed Stirling Engine

Posted by Leigh Kim in Stirling engine on December 28, 2012

Thingiverse, touted as “Digital designs for real, physical objects. A Universe of Things!” is a website for community sharing and feedback. Thinkiverse plugs itself is a place where creative, innovative people can share designs with the world, and the creators believe that just as computing shifted away from the mainframe into the personal computer, digital [...]

New Nuclear Reactor With a Stirling Engine Could Power Space Missions

Posted by Mila Luleva in Nuclear Power, Stirling engine on November 28, 2012

A new reactor concept that combines Stirling engine with modern heat pipe cooling system might provide power to upcoming space missions. The invention was created by a group of researchers from NASA and Los Alamos National Laboratory. The developers proudly show their simple, light and flexible design, which is easy to control. It is particularly [...]

Cool Energy’s Low-Temperature Stirling Engine Recovers Waste Heat as Electricity

Posted by Janina Lazo in Stirling engine on November 25, 2012

The SolarHeart®Engine is the new Stirling engine developed by Cool Energy that converts low-temperature (100oC to 300oC) heat energy to electrical power output ranging from 3 kW to 20 kW, making it suitable for solar thermal electric, biomass power, and waste heat recovery applications. As a participant at the Asia Pacific Clean Energy Summit’s Defense [...]

Video: Home-Made Stirling Engine Goes to 1687 RPM

Posted by Ovidiu Sandru in Stirling engine, Video on November 21, 2012

Stirling engines are rarely seen in the media, but they are actually one of the few options we have in turning raw heat to electricity. Indeed, some variations of the almost 200-year-old engine are more efficient than others, but it’s good to see experimenters from around the globe tackling them, and solving their shortcomings step [...]

Dean Kamen’s Stirling Engine Could Power Cable Installations

Posted by Benji Jerew in Energy news, Stirling engine on October 20, 2012

The Society of Cable Telecommunications Engineers [SCTE] Cable-Tec Expo finished today in Orlando, FL. Keynote speaker Dean Kamen holds over 400 patents worldwide, including an advanced human prosthetic arm for DARPA and the Segway Human Transporter. One of Kamen’s proudest accomplishments is founding FIRST® (For Inspiration and Recognition of Science and Technology), an organization dedicated [...]

Six-Cylinder Stirling Engine Built by DIYer in His Garage

Posted by Ovidiu Sandru in Stirling engine on October 15, 2012

Stirling engines have been touted as a good alternative for current internal combustion engines, since they can be powered with mostly anything that burns and are much simpler than steam engines for small applications like running a car. Here’s a guy who built a six-piston Stirling engine, at home, just to prove that this old [...]

Laser-Powered Micro Stirling Engine Invented by German Researchers

Posted by Ovidiu Sandru in Stirling engine on December 12, 2011

You know how Stirling engines work, don’t you? If you don’t you can make an idea by imagining a cylinder with a fixed quantity of gas inside that expands when hot and compresses as it loses heat, creating movement and perhaps moving a piston (just like in the picture). That’s a 200-year-old idea, but now [...]

The Stirling Racer: Nice But Expensive Stirling Engine Toy Powered By The Sun

Posted by Ovidiu Sandru in Pointless Green, Stirling engine on November 23, 2010

It’s nice for a toy, but difficult to understand when it comes to explaining the true greenness of this invention. A stirling engine-powered toy just hit the market recently, combining a 194-year-old engine concept touted today for its fuel flexibility with solar power-the baby that modern science wants to grow.

Evita: Hot Water and Important Electricity Savings From Stirling Engine-Equipped Boiler

Posted by Ovidiu Sandru in Stirling engine on November 9, 2010

I thought Stirling engines can offer great advantages if used in cars, but it never crossed my mind using such an engine in a heating boiler for your household. Evita is the name of the latest boiler made by Remeha, a Dutch company, using a Stirling engine to produce electricity and upload it to the grid.

How to Measure a Stirling Engine's Efficiency (video)

Posted by Ovidiu Sandru in How to..., Stirling engine, Video on May 21, 2010

The next video shows a Stirling engine while working to achieve its best, powered by a 70W light bulb. The poster also shows how he measured various parameters of the engine, like speed, torque, input/output power.

Panasonic Revives The Stirling Engine For 10 kW Waste Heat Recovery System

Posted by Ovidiu Sandru in Stirling engine on May 18, 2010

estir Co., an in-company venture of Panasonic led by Teruyuki Akazawa, thought that it would make a good business reusing the otherwise wasted heat from Panasonic’s plants, and reimplemented Stirling engines, seeking to make them more efficient than ever.

31% Efficient Stirling Engines Used to Convert 1.5MW of Arizona Solar Power

Posted by Cristi in Solar Power, Stirling engine on January 2, 2010

Stirling engines are known to mankind for about 200 years but they are not so widely used today, except maybe for the pacemakers and long-distance robotic spacecrafts. This will soon change as 60 stirling engines will be used in Phoenix, Arizona, to harvest solar power which will be converted into electricity.

NASA Planning to Use Nuclear Powered Stirling Engine for Moon Base

Posted by Ovidiu Sandru in Nuclear Power, Stirling engine on October 27, 2009
