Paper Title :: Possibility of tall towers in India for capturing uninterrupted solar energy
Author Name :: Dr. Heleena Sengupta || Arun Kumar Chakraborty

Page Number :: 01-10
This paper presents an ambitious new idea of constructing Tall towers in India for capturing uninterrupted solar power. India presently depends mainly on coal fired thermal plant which is outdated in most of the advanced countries for pollution aspect. Nuclear power plants are not possible in the present context for socio-economic-political reasons in India. On the other hand, wind energy and hydro power available is not sufficient to cater all over India. Moreover, present system of collecting solar energy requires large area and is climate dependent (i.e not suitable in cloudy or rainy seasons). So, construction of one km & above high circular shaped chimney type towers can be used only for uninterrupted solar power as such towers would raise solar panels above obstructing geological features or above cloud level, and expand the surface area available for uninterrupted solar power generation. The amount of solar power that could be gathered from these regions depends on how tall a tower can be built to support the solar panels. The present paper proposed the possible location in Bangalore (southwest part) for such high tower due to lower earthquake and wind load as it is in earthquake zone II as per IS 1893 part 1 (2016) and basic wind speed 33 m/s as per IS 875 Part3 (2015). The circular piled raft type foundation is also very much feasible in this location because the hard bedrock is available below 8.5m from the ground level. Interestingly, the maximum height of cloud level in Bangalore is generally about 450 m (as per the data available) above the ground level. So, construction of 1km tall tower is proposed at Bangalore (southwest part) in this paper. The top 500m height above the cloud level may be used to provide more than 6.0 MW uninterrupted solar power generation.
Key Words: Tall tower, uninterrupted solar energy, Bangalore, earthquake & wind load, piled raft foundation.

In humanoid robotics, imparting dexterity and autonomous competence to a robotic system is a substantial burden, especially in the sectors of industrial manufacturing, prosthetics, orthopedic rehabilitation, and so on. Operating a humanoid hand requires a very inventive actuator and gearbox system. Under-actuated principles are proven to be an effective way of generating particularly dexterous robotic hands without requiring a diversified mechanical design. The fundamental characteristics of an under-actuated robotic hand are that it requires fewer actuators to function than degrees of freedom. The under-actuated equivalent hand is much more affordable than the fully-actuated equivalent hand and considerably reduces the control system's complexity. The existing work dealt with the design and analysis of a three fingered underactuated robotic hand for grasping variety of objects with dexterity. The hand is underactuated one which is used for grasping of objects with less number of actuators and the degrees of freedom is more than the number of actuators. The design and analysis is performed by ADAMS software.
