SYNOPSIS An analysis is developed for the soiar chimney, aimed particularly at deriving overall efficiency and significant performance data. Numerical values are consistent with available information on the 200 m solar chimney at Manzanares, Spain, and projected designs. Overall efficiency is directly related to the height of the chimney and is shown to be about 1% for a height of 1000 m. It is concluded that the solar chimney is essentially a power generator of large scale.read more

Parking the power: Strategies and physical limitations for bulk energy storage in supply–demand matching on a grid whose input power is provided by intermittent sources
TL;DR: In this paper, it is shown that, in a sustainable energy future, energy for the electricity grid will probably be derived largely from the renewable sources of wind and solar radiation, because both are intermittent, any infinite busbar grid supplying a metropolitan area must necessarily be buffered from these intermittencies by massive energy storage on the gigawatt-day level.
