620325 Stirling Engine - ABRA Electronics Inc. - 0 views

  • The 620325 Stirling Engine by Thames and Kosmos uses renewable energy from the sun to drive a generator, which charges a rechargeable battery to power an electric car.
  • Power a Car with Solar Generated Electricity       Discover the Stirling engine, a simple, clean and efficient energy technology that is quickly becoming a viable source of electricity as the availability of fossil fuels declines. The Stirling engine in this kit uses renewable energy from the sun to drive a generator, which charges a rechargeable battery to power an electric car. Named after its inventor, Robert Stirling, the original Stirling engine dates back almost 200 years. Today, high-tech Stirling engines are being used in arrays of giant mirrored solar collectors and common applications like compact generators. NASA is even working on using Stirling engines to power a human outpost on the moon!Like a steam engine, a Stirling engine is a heat engine that converts heat energy into mechanical work, usually to drive a generator that then converts the mechanical energy into electricity. But instead of water and steam, the Stirling engine uses a permanently enclosed volume of gas, such as air or helium, to perform the mechanical work. Stirling engines are highly efficient, can operate very quietly, and can use many different sources of heat: combustion of fuels, nuclear fission, geothermal, or solar heat, as this model uses. The Stirling engine in this kit is located in acharging station with a mirrored parabolic dish. The dish focuses the sun’s rays onto the cylindrical glass bulb of the Stirling engine to heat it up. The air inside the bulb heats up and pushes a piston, which turns an electric generator. The generator produces electricity that charges a rechargeable battery in the car. The car runs on an electric motor powered by the battery.The kit includes the charging station with a beta type Stirling engine, the electric car, and a full-color, 64-page manual.

U49325 Sun Runner Stirling Engine - ABRA Electronics Inc. - 0 views

  • The U49325 Sun Runner Stirling Engine is a solar-powered Stirling Engine which offers a dramatic demonstration of energy conversion.   This motor and its parabolic mirror can be attached to any conventional camera tripod. When properly aimed at the sun, the polished aluminum parabolic mirror focuses incoming solar energy on the heat cap of the engine, which is converted to rotary motion. Unit comes complete with motor, parabolic mirror, and wrenches. Standard camera tripod is not supplied. This engine is completely assembled and ready to run. Each unit is test run at the factory prior to shipping. Motor runs at 2,000 RPM and up. This engine can also run as a horizontal engine with an alcohol burner. Demonstrate this exciting method of harnessing the sun’s clean and renewable energy to your students.  Weight: 6.00 lbs Dimensions: Engine: 8.25 x 3 inches (L x W) Flywheel: 3.25 inchesParabolic Mirror: 18 inch diameterPlease note that this item is designed to demonstrate the operating principles of a Stirling engine for educational use and is not designed for power production.  It can potentially be coupled with a generator for producing very small amounts of electricity but is incapable of powering anything beyond a small light bulb or LED.

XMPP - Extensible Messaging and Presence Protocol - Wikipédia - 0 views

  • Extensible Messaging and Presence Protocol
  • Extensible Messaging and Presence Protocol (qu'on peut traduire par « protocole extensible de présence et de messagerie »), souvent abrégé en XMPP, est un ensemble de protocoles standards ouverts de l’Internet Engineering Task Force (IETF) pour la messagerie instantanée, et plus généralement une architecture décentralisée d’échange de données. XMPP est également un système de collaboration en quasi-temps-réel et d’échange multimédia via le protocole Jingle, dont la Voix sur réseau IP (téléphonie sur Internet), la visioconférence et l’échange de fichiers sont des exemples d’applications.

Feed43 : How It Works - 0 views

  •  
    Feed43 engine converts free-form HTML or XML documents to valid RSS feeds by extracting snippets of text or HTML by means of applying search patterns, and then joining these snippets together using output templates to form user-friendly content of feed's items. The principle of extracting specific data from source documents is also known as "HTML scraping".

Internet Census 2012 - 0 views

  • Internet Census 2012
  • Carna Botnet
  • Abstract While playing around with the Nmap Scripting Engine (NSE) we discovered an amazing number of open embedded devices on the Internet. Many of them are based on Linux and allow login to standard BusyBox with empty or default credentials. We used these devices to build a distributed port scanner to scan all IPv4 addresses. These scans include service probes for the most common ports, ICMP ping, reverse DNS and SYN scans. We analyzed some of the data to get an estimation of the IP address usage. All data gathered during our research is released into the public domain for further study.

Solar power, with a side of hot running water - 0 views

  • The conversion of sunlight into electricity has been dominated by photovoltaic and solar thermal power generation. Photovoltaic cells are deployed widely, mostly as flat panels, whereas solar thermal electricity generation relying on optical concentrators and mechanical heat engines is only seen in large-scale power plants. Here we demonstrate a promising flat-panel solar thermal to electric power conversion technology based on the Seebeck effect and high thermal concentration, thus enabling wider applications. The developed solar thermoelectric generators (STEGs) achieved a peak efficiency of 4.6% under AM1.5G (1 kW m−2) conditions. The efficiency is 7–8 times higher than the previously reported best value for a flat-panel STEG, and is enabled by the use of high-performance nanostructured thermoelectric materials and spectrally-selective solar absorbers in an innovative design that exploits high thermal concentration in an evacuated environment.
