As the population of India grows exponentially day by day, there is an equal rise in energy demand to meet the needs of the masses. Moreover, we have very low amounts of non-renewable energy resources. So, the most viable alternative is to effectively use the renewable sources of energy.

A rotary solar furnace is conceptually introduced. In contrast to a conventional solar furnace, where the concentrator is fixed, in a rotary solar furnace both the concentrator and the heliostat rotate in concentric circular path around the concentrator's focus such that at each instant of time they face each other.

Solar Differential Rotation and Oblateness
Science, 1969An investigation of the time development of differential rotation produced by the solar wind torque indicates that the sun has a rapidly rotating core.

Photospheric and chromospheric spectroscopic Doppler rotation rates for the full solar disk are analyzed for the period July, 1966 to July, 1978. An approximately linear secular increase of the equatorial rate of 3.7% for these 12 years is found (in confirmation of Howard, 1976).

Solar radiation and solar differential rotation
Solar Physics, 1988Areas of sunspots and their positions taken from the Greenwich Photoheliographic Results (1874–1976) and typical intensities of the umbrae and penumbrae are used to calculate daily values of the solar flux at a wavelength of about 500 nm. Using overlapping time series of 512 days each solar rotation periods are determined by Fourier transformation. The

Solar rotation and solar wind–magnetosphere coupling
Planetary and Space Science, 2005Abstract This paper deals with three characteristics of the interplanetary magnetic field (IMF), important for solar wind–magnetosphere coupling and related to solar rotation: the IMF azimuthal component, the IMF total magnitude, and the handedness or the sense of rotation of magnetic clouds. The IMF configuration is described by Parker's Archimedian

The subject of solar rotation, or more properly rotations, has become of considerable interest in the last few years. These new developments are primarily associated with spacecraft observations, including observations of the interplanetary medium near the earth, and with improved ground-based solar telescopes and digital data-handling facilities.

The helioseismic determination of the angular velocity distribution within the sun is discussed. In particular, the bulk of the radiative interior of the sun is rotating at more-or-less the same rate as the photosphere. The latitudinal variation of angular velocity appears to change quite abruptly immediately beneath the base of the convection zone ...

Differential solar rotation depends on solar activity
Nature, 1979SUNSPOTS have long been used as tracers to determine the rotation rate of the Sun. Scheiner1 noted 250 years ago that low-latitude sunspots rotate more rapidly than those at high latitude (‘differential rotation’). In a recent review, Howard2 stressed the limitations of the sunspot technique for determining rotation rate and differential rotation, as ...

The secular evolution of the stellar rotation through angular momentum loss, driven by the stellar wind, and the consequences of the angular momentum transfers between orbit and spinning components in binary star systems will be reviewed with the special emphasis on the Solar rotation.
