Footstep Power Generation Using Piezoelectric Sensor

Man has needed and used energy at an increasing rate for the sustenance and well-being since time immemorial. Due to this a lot of energy resources have been exhausted and wasted. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India where the railway station, temples etc., are overcrowded all round the clock. When the flooring is engineered with piezo electric technology, the electrical energy produced by the pressure is captured by floor sensors and converted to an electrical charge by piezo transducers, then stored and used as a power source. And this power source has many applications as in agriculture, home application and street lighting and as energy source for sensors in remote locations. This paper is all about generating electricity when people walk on the Floor. Think about the forces you exert which is wasted when a person walks. The idea is to convert the weight energy to electrical energy The Power generating floor intends to trans- late the kinetic energy to the electrical power. Energy Crisis is the main issue of world these days. The motto of this research work is to face this crisis somehow. Though it won't meet the requirement of electricity but as a matter of fact if we are able to design a power generating floor that can produce 100W on just 12 steps, then for 120 steps we can produce 1000 Watt and if we install such type of 100 floors with this system then it can produce 1MegaWatt. Which itself is an achievement to make it significant. Keywords: Piezoelectric sensor, Footstep, remote location, force and pressure, power generation

Evolution of properties of macadamia husk throughout gasification: hints for a zero-waste energy production system

In-depth information about the transformation of biomass during gasification is the key to the sustainable development of this technology. This study elucidated the evolution of physico-chemical properties of macadamia husk throughout relevant industrial gasification conditions. The technical characteristics combined with high kinetics highlighted the suitability of this feedstock for gasification. Non-porous chars with very low surface areas were observed throughout the conversion, which minimizes the potential to use the residues after gasification as adsorbents. Nevertheless, multiple carboxyl and hydroxyl functional groups were present on the char surface. Moreover, an extraordinarily high K content was detected (up to 86 wt% of the char’s total inorganic elements) and evenly distributed on the char surface. Such results consolidated the idea of combining the production of energy and cheap bio-fertilizers using the gasification of macadamia husk. The resulting database offered interesting hints for the development of zero-waste energy production systems with biomass gasification.

Rice husk as sustainable waste energy for small farmers - A review

A review of rice husks as an energy source was carried out to provide information on their use in the drying process, especially handling post-harvest for small farmers. This is done because there are still many small farmers who only use the sun to dry their food. Drying is done by dry in the sun and this process still has drawbacks. The weakness of the process of drying in the sun is very dependent on the weather, so when it is cloudy or rainy the drying process will stop. Of course, this causes losses to small farmers, on the other hand, waste is abundant in the form of rice husks. This is related to rice as the farmer's staple crop and rice husk is a by-product of rice production. Based on several studies and libraries, a satisfactory result was obtained regarding rice husks. Rice husk can be used as sustainable alternative energy. Increasing the drying temperature, it can be done through an energy conversion process. This method is carried out by adding a heat exchanger to increase heat transfer from the burning of rice husks to the drying air. This method is also able to shorten the drying time and the dried food becomes hygienic. This is as a result of the drying process of foodstuffs carried out in the drying room, to avoid dirt and dust. Utilization of rice husks and heat exchangers as an alternative in overcoming the problems of conventional agriculture in terms of uncertain weather and climate.

Six-Stroke Cylinder Engine : An Emerging Technology

The requirement for the advancement of internal combustion (IC) engines and enhance methods for the combustion cycle is increasing day by day. The four-stroke combustion engine is extensively used due to better fuel economy and less exhaust smoke. However, the major drawback includes a considerable amount of extra heat energy generation that directly adds up to waste energy. In order to overcome the limitation, the idea of computing two extra strokes in the four-stroke engine to utilize the waste energy has been introduced. The six-stroke engine has significantly improved the fuel working ratio per cycle. Incorporating alternative fuels like hydrogen and HHO into six-stroke technology increases efficiency and minimizes exhaust emissions. A six-stroke engine could be the solution for making hybrid automobile technology more convenient. The review article aims to thoroughly understand the underlying principles behind the improved efficiency of a six-stroke cylinder engine. The researches on the six-stroke cylinder engine are summarized in the literature review. The design configuration of alternative fuels is discussed towards the end of the paper.
