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

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

  3. We obtained this.

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

  5. The tension is 0,7 V.

  6. The intensity is almost 7 mA.

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

  8. We have 1,5 V …

  9. … and 10 mA.

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

  11. … and voltage.

  12. The LED is lighting!

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