This document describes a piezo-electric shoe that generates electricity from the kinetic energy of walking to charge an internal battery. Piezoelectric crystals produce voltage when pressure is applied, and placing these crystals in the shoe's insole harness the energy from each step. The battery stores the accumulated charge to power small electronics without needing plugs or cables. While a prototype generated only small amounts of power, future designs may improve efficiency by an order of magnitude, making piezo-electric shoes a practical way to scavenge renewable energy from normal walking.

DC Fast Charger and Battery Management System for Electric Vehicles
This document discusses the development of a DC fast charger and battery management system for electric vehicles. It aims to reduce charging times for EVs by designing an efficient charging mechanism. A PIC microcontroller controls the charging voltage and a battery management system monitors battery temperature, voltage, current and provides notifications. The system uses a step-down transformer, rectifier, voltage regulators and temperature sensor to charge lithium-ion batteries safely and quickly, while the battery management system protects the batteries from overcharging or overheating. Faster charging times through more charging stations could encourage greater adoption of electric vehicles.
Coin-Based Mobile Battery Charger Using Solar Panel
Abstract: The coin-based mobile battery charger developed in this paper is providing a unique service to the rural public where grid power is not available for partial/full daytime and a source of revenue for site providers. The coin-based mobile battery charger can be quickly and easily installed outside any business premises. The mobile phone market is a vast industry, and has spread into rural areas as a essential means of communication. While the urban population use more sophisticated mobiles with good power batteries lasting for several days, the rural population buy the pre-owned mobile phones that require charging frequently. Many times battery becomes flat in the middle of conversation particularly at inconvenient times when access to a standard charger isn't possible. The coin-based mobile battery chargers are designed to solve this problem. The user has to plug the mobile phone into one of the adapters and insert a coin; the phone will then be given a micro-pulse for charging. It does not bring a mobile from 'dead' to fully charged state. The charging capacity of the mobile is designed with the help of pre-defined values. It is, of course, possible to continue charging the mobile by inserting more coins. This compact and lightweight product is designed to cater for the growing number of rural mobile users worldwide. A suitable microcontroller is programmed for all the controlling applications. The source for charging is obtained from solar energy and back up storage battery in case of non-availability of solar energy.

IRJET - Efficient Energy Harvesting and Reusing System
The document describes a proposed system to efficiently harvest and reuse energy from human footfalls. Piezoelectric sensors placed under walking surfaces like floors or pavements would convert the kinetic energy of footsteps into electrical energy. This energy would be stored using a boost converter to increase the voltage before storing it in batteries. An inverter would then convert the stored DC energy into AC power that can be used to power devices. The system aims to address rising energy demands by utilizing wasted kinetic energy from walking. It could be implemented in populated areas to passively generate electricity from human foot traffic.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Pretty much any person with a mobile phone/device has experienced that frustrating moment when a device fails to complete its task due to a lack of energy. My project is designed to fix this problem in a way that promotes health by creating a shoe insole that converts the physical energy created by walking into electricity, which is then stored in a portable battery pack. This way, you will always have an emergency power source (and you will be renewing some of your own physical energy too)! Piezoelectricity was present ever since mid-18th century. Piezoelectricity is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics in response to applied mechanical stress. This sounds familiar! Yes they do, you can actually find those piezo elements in your old/ outdated earphones from the 90's.
