CONTACT US for technician support, we have video problem shoot instruction . A special mini magnet stick in the bottom of alcohol lamp bottle, it make the bottle can attached to the stirling board and avoid drop by vibration during stirling working. With the help of the flywheel, this engine run madly. Because of the heat from highgrade alcohol,the engine will run madly and creat the electricity. It's really interesting and imaginative toy.. It is a amazing and fantastic product at this price,it can be a great gift to your families or friends. It also can be used for teaching purpose. Many of our customers comes from school,colleague,etc. How it works? This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid,the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.
Photovoltaic Energized Vehicles Science Kit Build your own solar-powered models and discover how solar cells generate electricity from light. Build six solar powered models including a locomotive, single-prop plane, bulldozer, helicopter, backhoe, and twin-rotor helicopter. The special solar panel in this kit consists of three solar cells and generates 1.5 volts of electricity in bright sunlight, like a AA battery. A unique cradle holds either the solar panel or the battery, allowing you to switch out the solar panel for a AA battery (not included), depending on the strength of sunlight. You can even use the solar panel to charge up your own rechargeable AA batteries. The solar panel is positionable, so you can maximize its exposure to the sun to generate the most power. The 24-page color instruction book included in this kit gives step-by-step instructions for assembling the six model vehicles. After you have built the suggested models, you can design your own solar vehicles. Compete with your friends to see whose solar vehicle runs the fastest! The 177 building pieces included in this set are compatible with those in all Thames and Kosmos Construction Series kits, Physics Series kits, Wind Power, and Hydropower Kits. Ages 8 and up. All Thames and Kosmos products have been safety tested to the rigorous standards of both the USA and Europe.
In one way or another, almost every form of energy we use originates as energy from the sun. Solar energy directly powers photovoltaic cells and thermal collectors. Indirectly, we get power from plants grown by the sun, oceans heated by the sun, and Earth's weather systems sustained by the sun. Even the energy stored in fossil fuels originated as energy from the sun, captured by plants and animals millions of years ago. Physics Solar Workshop explores the topic of solar energy, focusing on photovoltaic cells. By building five awesome models and conducting experiments with them, you will learn how solar cells transform light into electrical energy, and how motors and mechanical devices can optimize the work done by this energy. Start with a simple helicopter model that converts sunlight into a rotating motion and demonstrates the basics of solar technology. Continue your experiments by constructing increasingly complex models: a solar-bot, a moon rover, and a stag beetle. Finally, build a cool praying mantis model that moves like an insect and is powered by a solar cell. The models can also be powered by a battery, allowing operation in all lighting conditions. There are 138 parts, which are compatible with other Thames & Kosmos physics and engineering kits. The 48-page book offers illustrated step-by-step instructions for the projects. - A Parents' Choice Silver Award Winner.

Now you can harness the power of Mentos candies and soda into a racing car that travels 200 feet or more! As soon as you release the Mentos into the soda, the car is off. Strap the soda bottle onto the chassis, add decals to the nosecone and you're ready to "Start Your Engine." Learn why this works so well and experiment with other types of car power. Experiment with other types of "fuel" with the included Depth Charger. Use the included needle and rubber stopper to convert to an air pump system.
Features ROW! Let's turn back time when the Vikings used to cross the Atlantic or to sail east. The hard rowing crew used the rolling method to maneuver their large, silent, swift ships through rivers and into the open waters of the Black Sea. The evolution of the 21st Century version of OWI's Valiant Viking Ship is similar in nature but uses alternative energy principle, solar, to power its way through water. The sweat drenched Vikings would have welcomed and appreciated the new and improved method of propulsion. It would appear the Valiant Viking Ship is smiling as the sun shines providing its rhythmic splashing, as the oars penetrate the water's edge to create movement. You can almost hear the cheers of the Vikings as they standby and watch the alternative energy principle demonstrate its marvel. Upon completion of its journey, one can moor the ship on its docking station (included). No batteries required and 33 plastic parts to assemble. It's most advantageous because: it's very inexpensive for individuals or groups; clear easy to follow instructions; motivates students to learn about solar energy; a great self-contained take-home project for boys or girls clubs; challenges young people to be technically precise with miniature parts; teaches students to follow precise visual diagrams; have hours of fun experimenting with solar energy. Solar Panel Output : 1.1V x 50mA Assembled Size : 170mm x 200mm x 105mm Solar Cell Life : 2 yrs in normal use Motor: DC Power Consumption : 1.2V x 10mA

The solar powered robot can be transformed into 14 different robot modes that include a multitude of comical and functional movements. Easily change from a wagging-tail dog - running beetle - walking crab - surfer - speedster - zombie chaser and more. The robot kit provides unique accessories and parts that make robot move on land or water or both. With alternative energy playing such a pivotal role, there is no better time than now to start children on the path to learning basic concepts behind these technologies. Fortunately, all the 14-in-1 robots are powered by the sun, so no batteries required. The robot moves in direct sunlight and allows children to create and use their infinite imagination. There are two levels in building robot version. Level One includes: Turtle-bot, Beetle-bot, Quadru-bot, Boat-bot, Walker-bot, Dog-bot and Wheel-bot. After children explore entry level designs, they can challenge their manipulative skills with Level Two projects: Roly Poly-bot, Auto-bot, Slither-bot, Surf-bot, Zombie-bot, Crab-bot and Row-bot. Additional features include: adjustable polarity on the solar panel to change direction of motor rotation, retractable robot head which can be quickly stored in the upper body, the robot head can be installed in the front, top or rear of the gearbox and transparent housing to see the movements of the gears. As we all say, ""Our children are the future"". And if anything is certain about that future, it is that renewable energy sources and green technologies will play a major role in our children's lives. With 14-in-1 Educational Solar Robot Kit, let them learn about their future and have fun at the same time. This solar powered robot can be transformed into 14 different robot modes Powered by the sun - no batteries required Two levels of building skill levels so the beginner and experienced robot builder will be equally engaged Excellent addition to a home-school curriculum
