There are sources of electricity that we never knew of, but might be handy some day when the power goes oit.

About This Video

http://www.FreeScienceLectures.com


The best physics lecturer Walter Lewin makes another wonderful physics demonstration after having read a lecture on batteries.

The battery he creates has a huge potential difference - 10 to 20 kV!

You'll never believe what it's made of!
It's made of two cans with bottom and top open and two other cans. And then water is let to drip through the two open ones.

After a short period a spark comes up, then another one, then another one.

Do you know how it works? If not, see the free electricity and magnetism video course by Walter Lewin at MIT's OCW!
