Modeling of a plasma column produced and sustained by a traveling electromagnetic surface wave

Abstract: We present an improved model of a plasma column produced and sustained by a traveling azimuthally symmetric electromagnetic surface wave. The axial density profile of the column as well as the wave dispersion and field and power characteristics are now specified by five parameters: (i) the collision frequency for momentum transfer ν, ν<ω (ω being the wave angular frequency), (ii) the number σ=ωR/c (R is the plasma column radius, c the speed of light), (iii) the number β indicating the gas‐discharge regime (B=0 for the diffusion regime and 0<β≤2 for the bulk recombination one), (iv) the permittivity of the container (glass tube) ed, and (v) the number γ=1+d/R (d denoting the thickness of the tube), the last two parameters having been neglected earlier. The influence of ed and γ on the wave dispersion properties and the axial profiles of the plasma density, wave power, and wave electric field components has been studied numerically. Our improved model is tested with the experimental data [A. Sola, A. Gamero...

Studies on Wave and Tidal Power Extraction Devices

Abstract: Electric power from wave and tidal power is a form of pollution free and echo-friendly renewable energy which has a huge potential. This potential has not been realized high capital costs and environmental concerns. This paper discussed how the two problems could be resolved utilizing small scale technologies, innovative financing, and involving local communities of the coastal areas to ensure that all key impacts are manageable. Bangladesh has 710 km long coast line and long coastal area with 2~8 m tidal head/height rise and fall, most of which is protected against flooding by embankment and sluice gates. Therefore, the potential for wave and tidal power in the country is significant because the barrages necessary for creating controlled flow through turbines (to tap tidal power) are also needed for flood control. The wave climate has been studied for a long time at the coastal belt of Bangladesh. It has been shown that it is feasible to generate electricity using the Bay of Bengal. Our research study showed that all twelve months of the whole year are not feasible for wave and tidal power production but 8 months of the year (from the late March to October) are most suitable, feasible and viable for power production

Iswec: A Gyroscopic Wave Energy Converter

Abstract: Wave Power: how to produce clean electric energy from sea waves. Thousands of patents have been filed, hundreds of devices have been studied and tested in labs and tens of prototypes of Wave Energy Converters (WECs) have been deployed to the sea successfully harvesting wave power. The main research work has been carried out for the oceans, the most relevant source of wave energy. Closed seas, like the Mediterranean Sea, have smaller energy availability, but they have a particular feature: short waves. Short waves have higher frequency and can activate a WEC in a very effective way. For instance a WEC carrying a gyroscope-based energy conversion system harvests power proportionally to the square of the wave frequency. Gyroscopic effects can keep a spinning top in a quasi vertical position, guide airplanes, stabilize ships and, with some different architecture and strategy, harvest energy from sea waves!
