Energy from salt and water The 3-rd experiment of the Romanian team

Alexandra puts in a glass a solution of water with salt.

We obtained this.

Loredana and Cosmin connect the glass with solution to the voltmeter.

The tension is 0,7 V.

The intensity is almost 7 mA.

We put solution in one more glass and we connect them.

We have 1,5 V …

… and 10 mA.

We connect the third glass with solution and we measure intensity…

… and voltage.

The LED is lighting!

We saw that we can obtain energy from water and salt. Liked it.
