The ener~y hindrance in 1973 and 1979 initiated a number of actions and courses for high and low temperature applica­ tion of solar power. man made fuels and chemical substances produced through solar power is one in every of them, the place temperatures within the variety of 600-1000°C or maybe better are wanted. In precept such excessive temperatures might be produced in sunlight towers. For electrical energy tower vegetation creation, the feasibility and operation of sun solar energy has been tested through the SSPS - venture (Small procedure) in Almeria, Spain. expand the target of sunlight Thermal strength usage is to box the event from the previous SSPS - software in to the of sunlight produced man made fuels. New fabrics and technolo­ gies must be constructed so as to learn this target. steel parts now in use for sunlight receivers have to be more advantageous with admire to brief operation or potentially changed by means of ceramics. extreme temperature approaches, like steam-methane reforming, coal conversion and hydrogen produc­ tion must be constructed or at the least tailored for the unconven­ tional sunlight operation. hence sun Thermal power Utiliza­ tion is a protracted time period application, which wishes time for its boost­ ment even more time than the durations anticipated in among additional strength situation. The "Studies on expertise and Applica­ tion on solar power usage" is an important step within the correct path so that it will arrange for the power difficulties within the future.

4. 7 contains all the quantities mentioned above. Examples are calculated for January and July, based both on Esol and E(O = 50) for comparison with the measured values of the beam insolation. This again shows the additional energy gained by including the aureole. 16). 0 Available solar radiation when E >300 wm-2 in hours per month 196 209 338 343 The maximum values of the measured beam insolation coincide with the beam insolation calculated from the minimum measured optical thickness, the m~n~mum relative air mass and no cirrus.

The minimum values of the optical thickness dAE from the four years for which measurements are available show the annual variation with a maximum in summer. 85. The amount of water vapour over Tabernas is read from maps of Tuller (1968). 6. The maximum in summer is caused by the water vapour saturation rising with temperature. 6 ozone is given from Gebhardt et al. (1970). 6 is taken from Moller (1970).
