  Single slope solar still absorbs the thermal energy from sunlight to distillate polluted water into clean water in an enclosed space. Principal of heat transfer and energy balance were the governing equations for the operation of single slope solar still. A mathematical model was developed to express these thermodynamics behaviours. In the model, critical parameters had been identified, such as slope angle of glass cover, mass of water in basin and wind speed. Simulation had been carried out and results revealed the importance of the slope angle matching the latitude of the experimental location, the increasing of water mass in the basin leading to decreasing of clean water production and the presence of wind speed also increase the output only when the sunlight is still sufficient.

  Underwater autonomous device with capability of locomotion in liquid environment has become a popular area of interest as technology closes in the gap to match with reality. However, the nature in liquid environment is complex and it is current need to overcome maneuverability, mechanism robustness, speed, operation duration and control system that still pose a major challenge. Current trend of study are experimenting on aquatic animal inspired concept to mimic the mother nature of fish swimming to provide better option for a far more dynamic and efficient technique for underwater applications. This has motivated a brief review on the fish morphology and swimming mode, the underwater biomimetic fish modelling and simulation and finally the control system development so far.

  Fundamental fish swimming kinematic by sinusoidal fit consisting of smooth amplitude modulated travelling wave h(x,t) along the fish body from the nose to tail being a construe of wave amplitude envelope f(x) and a fish tail oscillation function g(t). Improved fundamental parameters by previous workers, such as the body wave speed (C), wavelength of body wave (λ), swimming speed (U), tail beat amplitude (A) and Strouhal-Number (St) were utilized in the simulation for designing the biomimetic robotic fish. Effects of these parameters on the swimming kinematic model had been developed for comparison between the Blacktip shark and biomimetic robot fish over a single cycle with 18 iteration of full fish body motion from nose to tail. Results showed that Blacktip shark could be seen to produce a more elongated body displacement shape as compared to the biomimetic robotic fish. Doubling the swimming speed (U) had also showed insignificant body motion change though increase in tail beat frequency and reduction of tail beat amplitude (A) and wavelength (λ) was obvious. The effect of doubling the tail beat frequency had also shown similar behavior as doubling the swimming speed.
