Creamy Chanterelle Mushroom Soup


A hearty and delicious fall soup. This soup gets better the longer it sits. Feel free to simmer it longer than 45 minutes even though it will still taste great when served right away!
  • PREP TIME
    10 mins.
  • COOK TIME
    45 mins.
  • 1 TBS coconut oil
  • 1 large yellow onion, finely chopped
  • 4 cloves of garlic, minced
  • 1/2 lb chanterelle mushrooms, cleaned and finely chopped
  • 1 15 oz can organic navy beans (or any other white creamy bean)
  • 3-4 cups organic vegetable stock
  • 1/2 cup organic coconut milk
  • 2 TBS low sodium tamari (or soy sauce)
  • a few pinches of crushed red pepper flakes
  • 1/4 cup parsley, tough stems removed and diced
  • salt and pepper to taste


Serves 4

  1. Heat oil in a large soup pot over medium high heat. Add onions and sauté for about 5 minutes stirring occasionally. Stir in garlic and cook for about 2 more minutes.
  2. Add chanterelle mushrooms and cook for about 5-8 more minutes stirring often. Add in the beans and vegetable stock (start with 3 cups of veggie stock and add more if the soup is too thick) Bring to a boil. Reduce heat and simmer. Add in the tamari and crushed red pepper flakes. Simmer for about 25 minutes.
  3. Carefully with an immersion blender or regular blender, blend the soup until most of it is smooth but leaving some chunks to add some texture.
  4. Stir in the coconut milk salt and pepper. Let the soup simmer for about 10 more minutes.
  5. Serve the soup warm with a healthy pinch or two of minced parsley and more salt and pepper if necessary
Please use this recipe as a guide. Adjust measurements and ingredients as necessary. Always taste test as you go.

Record-Setting Power, Reliability, and Efficiency in a Low Mass, Free-Piston Stirling Convertor


Technology developed through a series of Small Business Innovation Research (SBIR) contracts with Ohio-based Sunpower, Inc., in partnership with NASA’s Glenn Research Center has resulted in the Advanced Stirling Convertor (ASC), an 80-watt free-piston Stirling power convertor that produces electric power from any source of heat. The ASC can be used in any application that requires conversion of heat into electric power with high efficiency and low mass.
The ASC provides a state-of-the-art power conversion system for potential future NASA deep space and planetary missions enabled or significantly enhanced by the application of radioisotope power systems. Other terrestrial applications being considered are a liquid-fueled, soldier-carried, portable power system and an efficient portable solar-to-electric convertor.
The ASC consists of a free-piston Stirling engine and an integral linear alternator that converts the piston reciprocating motion to electrical output. Weighing just 1.3 kg, the lightbulb-sized ASC has evolved to demonstrate 38-percent conversion efficiency, extended operation, and a twofold improvement in specific power over competing power sources. The higher efficiency reduces the amount of radioisotope material or fuel required by a factor of 4 or more, thereby decreasing costs.
Key technologies that enable high efficiency and low mass are hydrostatic gas bearings, moving-magnet linear alternators, high-frequency operation, high-temperature hot end materials and fabrication processes, and high-temperature, high-porosity regenerators.  The ASC is similar in design configuration and size to thousands of commercial terrestrial Sunpower cryocoolers. The company has produced five generations of ASC-related hardware, evolving the technology progressively with each build. ASCs have been running continuously in Glenn’s test facilities to demonstrate their ability to be used in generators. Glenn has contributed its expertise in reliability testing, materials assessment and risk reduction, and has provided access to unique facilities that have allowed for more than 165,000 hours of testing and operation on ASC research and experimental models, as well as the prototypes for flight.
ASC development, funded by the SBIR program, began in 2001 as one of 10 competitively awarded contracts intended to address the power conversion needs of future radioisotope power systems. The convertor efficiency and low mass objectives were met early in Phase 1, with continued technology refinement and improvement in Phases 2 and 3. These successes led to NASA’s decisions to accelerate development by increasing technical support from Glenn and subsequently integrating the ASC in 2007 as a critical component of the Advanced Stirling Radioisotope Generator (ASRG) being developed by Lockheed Martin Space Systems Company for the Department of Energy. Dual opposed convertors are used in the ASRG to achieve balanced operation, and their use has led to more than a twofold increase in specific power when compared with radioisotope thermoelectric generators used in prior missions. The ASC’s small physical size, high conversion efficiency, capability for long-life operation, and high specific power make it a candidate for future deep space missions and military portable power systems. Potential space missions include providing electric power for deep space missions, surface rovers, and stationary power generators.

DLR team develops demonstrator of free-piston linear generator as range extender for EVs; technology transfer to Universal Motor Corp.

http://www.greencarcongress.com/2013/02/dlr-20120220.html

Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Institute of Vehicle Concepts in Stuttgart have developed a demonstrator multi-fuel free-piston linear generator (FPLG, or Freikolbenlineargenerator, FKLG in German) as a range extender for electric vehicles. The FPLG comprises an internal combustion component, a linear generator and a gas spring; the researchers have demonstrated the feasibility of the technology on a test bench specifically developed for this purpose.

The free-piston linear generator works in a similar manner to a conventional combustion engine, but instead of converting the linear movement of the piston into the rotational movement of the crankshaft, it generates electricity directly. A fuel-air mix is ignited in the combustion chamber. This expands and pushes the piston towards the gas springs. These springs decelerate the piston movement and push it back. The linear generator converts the kinetic energy of the piston into electricity and this in turn powers the electric motor. 

Research on this type of drive unit has been fairly widespread. As one example, GM Global Technology Operations LLC and the Regents of the University of Michigan recently were recently awarded a US patent (Nº 8,261,860) for a plug-in series hybrid or range-extended electric vehicle powertrain using multiple free piston linear alternator (FPLA) engines. (Earlier post.) As another, researcher at the Nanjing University of Science & Technology has proposed a novel opposed-piston free-piston linear generator for use in series hybrid electric vehicles. (Earlier post.)
The DLR researchers says that through the installation of a gas spring in their system, they have now succeeded, for the first time, in operating such a system in a stable manner. The control system devised by the DLR engineers is able, for example, to control piston movement accurately to within one tenth of a millimeter. At the same time, it recognizes fluctuations in the combustion process and compensates for them.
The challenge here was to develop a particularly powerful mechanism with a highly dynamic control unit that regulates the complex interactions between the individual component.

The core module operates at high efficiency even at partial load, with an indicated power of up to 35 kW per module; operating frequency is 40-50 Hz.

4 teaspoons chopped fresh jalapeno pepper (including seeds)
1/2 teaspoon ground cumin
