This set allows students to explore the important world of renewable energy, and helps them answer the question, “How can ecological electric power be produced?” Production, storage, and use of electricity from natural energy sources such as water, wind and the sun are graphically illustrated using various models and numerous experiments. This set, which is an upgrade of the previous Oeco Tech set, now includes two new solar modules. This not only guarantees more power; but the many new attachment possibilities ensure even more flexible use in the models. The Gold Cap included for power storage can release the stored power at a slower rate. This helps students to truly understand these energy forms of the future. This set can be combined with the new Fuel Cell Kit to allow you to build additional models and operate them with a fuel cell. Contains 370 components for building 14 different models. Also includes multi-language teaching and activity booklet as well as complete step-by-step assembly instructions. Parts include a solar motor (2V), 2 solar modules (1V; 400 mA), Gold Cap power storage device, and LED ON/OFF switch. Can be used in conjunction with the Fuel Cell Kit to build additional models. The fischertechnik system was created in 1964 by Professor Artur Fischer. A highly creative and prolific individual, Professor Fischer patented his first invention, a Photo Flash Light, back in 1949, and he currently holds 1080 patents in his name. He still hopes to someday surpass Thomas Edison, who recorded 1093 patents during his lifetime. The original fischertechnik construction sets were created as Christmas gifts for the customers and associates of Mr. Fischer’s nylon wall plug business. These initial sets proved so popular that he decided to release them on a larger scale. The sets were then featured on German television during Christmas of 1965, and later introduced to the retail toy market the following spring. The response was enthusiastic, and public demand led to many additional sets. And even now, almost 50 years later, fischertechnik sets are still highly in demand. Today, fischertechnik building sets are used and coveted around the world, not only by aspiring young engineers, but also in classrooms and labs, as well as industrial simulations and training.
