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. The battery is a metal-air
electrochemical cell, a type of battery that is
widely used in small scale devices. It is ideal
for demonstrating battery technology because
it does not use any harmful chemicals: it uses
only magnesium plates, salt water, and the
oxygen in the air to generate electricity. 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. Experiment with different
concentrations of salt to see how long
your battery can run. Learn about electrochemistry
and battery technology.
One metal plate lasts as much as six times
longer than a regular AA battery (six plates
included). Full-color, 64-page experiment
manual. 91 building pieces.
