No: the air is 6 times more compressed to 600 mm is will make more energy to relax.

2000 m3, that is 2 000 000 kg on a height of 20cm or 0,2m store an energy of 2 000 000 * 0,2 * 9,81 = 3 924 000 J or 1090 Wh or 1,09 kWhcortejuan wrote:As they are shallow (often one meter deep) we could go up 20 cm. On one hectare it is already a few m3 (2000 m3).
