Sentences with phrase «powered by condensation»
The presence of water ice, he says, supports the idea that Saturn's superstorms are powered by condensation of water and originate deep in the atmosphere, about 200 kilometers below the visible cloud deck.

The global science community still isn't entirely sure what caused the repeated cycles — there may have been larger oceans in the northern hemisphere that powered a hydrological cycle (evaporation, condensation, precipitation), or shorter cycles could've been caused by volcanic activity or asteroid / comet impacts.
The open cycle consists of the following steps: (i) flash evaporation of a fraction of the warm seawater by reduction of pressure below the saturation value corresponding to its temperature (ii) expansion of the vapor through a turbine to generate power; (iii) heat transfer to the cold seawater thermal sink resulting in condensation of the working fluid; and (iv) compression of the non-condensable gases (air released from the seawater streams at the low operating pressure) to pressures required to discharge them from the system.
Our estimates suggest that the global mean power at which this potential energy is released by condensation is around one per cent of the global solar power — this is similar to the known stationary dissipative power of general atmospheric circulation.
