We see smaller and smaller objects through naked eye and microscopes, from hair to atoms.

When two different types of conductors are pushed into a potato chemical reactions take place charging them up - we have a simple electrochemical cell. A potato, zinc screw and carbon rod produce about 1V. We experiment joining a few of these cells u....

This is a simple yet effective demonstration of electricity generation. 500 turns of wire are wound onto a 35mm film can and the two ends are attached to an LED light. A strong magnet is placed in the can and the lid fixed back in place. The generato....

When two different metals are placed in a salt solution (an electrolyte) the chemistry produces a voltage. This is called a cell. By wiring up a number of these cells we can make a battery and use it to power electrical circuits.

Converting wind power into electricity seems like an ideal way of helping to solve our energy problems. However, the power generated by a windmill is dependent on the wind speed. If the wind drops to half its speed there is as little as an 1/8th of t....
