Thames & Kosmos 620615 It?s looking increasingly inevitable that electric vehicles (EV's for short) will be the cars of the future. More specifically, battery electric vehicles (or BEV's) which are powered entirely by rechargeable chemical cells are starting to become practical. Many major auto manufacturers have BEV's in development, and a few already have BEV's on the road today. The challenge in making BEV's a viable transportation solution is the battery. Batteries must be easy to recharge, able to hold enough charge to drive long distances, and more efficient than gasoline engines. Scientists and engineers around the world are tackling this battery challenge, and major progress is being made. In this kit, you can build and experiment with a new type of environmentally friendly ?fuel cell? to learn about electrochemical cells and BEV's. Features: -Metal-air electrochemical cell type of battery that is widely used in small scale devices.-Ideal for demonstrating battery technology.-Does not use any harmful chemicals.-Uses only magnesium plates, salt water, and the oxygen in the air to generate electricity.-Experiment with different concentrations of salt to see how long.-Learn about electrochemistry and battery technology.-One metal plate lasts as much as six times longer than a regular AA battery.-Moreover, magnesium is considered an eco-friendly renewable fuel because it could be harvested cleanly from ocean water.-Build 20 different models and power them with this special battery.-Ages 10 and up.-22 Experiments.-Full-color, 64-page experiment manual. 91 building pieces.-Gender: Boy.-Category: Science.-Minimum Age Requirement: 8 Years And Up.-Age Start: 10 Years.-Age End: And Up.-Collection: Construction Series.Dimensions: -Overall Height - Top to Bottom: 16.8.-Overall Width - Side to Side: 11.5.-Overall Depth - Front to Back: 3.2.-Overall Product Weight: 2.4.
