/ Perpetual water engine can be created! /
How many secrets exists in nature, so many secrets there is in the molecule of water.

In basis of consideration of properties of Water in given clause lays scientific concept of "Time" existing «Up to during existence Ancient Egypt », as        « Energy of the Stretching » working in all universe in counterbalance with «Energy of Compression », named force of Gravitation. And the main element, in which this force "Stretching", as Time, is shown by strongest way "Water" is.

Therefore the valid explanation, that water is basis of all alive on the earth and in all universe, it that Water in all alive organisms is "Intermediary" for reception space Energy from space of the universe. Therefore only due to properties of water «to accumulate space energy and to transform it to energy of movement and electric energy», water  has taken such central place in the universe. And all most complex systems alive do not live without water, and the most simple alive systems do not activate the action without water
