The document summarizes a design for an exercise device that powers electronic devices through pedaling. The device is inspired by a recumbent bicycle and aims to allow comfortable exercise while watching TV. It must be safe, comfortable for long periods, adjustable for different heights, easy to start pedaling, and able to power various devices. The electrical system will either directly store energy from a generator in batteries and convert it to AC, or indirectly use stored energy to activate a switch connecting an appliance to a power source. The designers are concerned about pedals sliding and battery life being too long, and propose solutions.

motionless electromagnetic generator
THOMAS E.BEARDEN has invented and patented in 2002 by a group led by Bearden a free energy device called “MEG” .
This device transforms the magnetic force of a permanent magnet into electricity and achieves over unity.
Semi Perpetual Motion Machine(ppt)
This document describes a semi-perpetual motion machine designed by Harsh Gupta. It works on the principle of centripetal force using a system of gears, shafts and bearings. The central gear provides rotation to three outer gears. Weights are added to the outer gears to provide a high rotational force from a small manual input. While perpetual motion violates thermodynamics, this design aims to generate more power output than input using centrifugal and rotational forces. Potential applications include power generation for irrigation in times of drought.
Electricity generating staircase
This project aims in creating a mechanical system capable of utilizing the mechanical energy during walking, running or climbing that would otherwise have gone to waste, in producing electrical energy that can be used for various other purposes. It uses a chain drive which is attached on the sprocket and a chain locking system is attached at the two ends of the chain which helps in moving the chain uniformly. Then a spring is also attached to the base of the step which helps in bringing flexibility in the step used that helps in moving the chain. After the chain is rotated then the dynamo is attached to it which generates electricity. This design helps to increase the efficiency of the energy production since this system uses less input to produce more output.

It would involve placing sensors on speed breakers and roads to capture the kinetic energy from passing vehicles and walking people. A prototype was built using piezo and force sensors connected to an Arduino board and LEDs. The project aims to provide a low-cost source of pollution-free electricity. It discusses components, circuit diagrams, code, and presents the project's second place win at a tech competition. The conclusion emphasizes the need for alternative energy sources like this to address future energy demands.

Provincial Qualifications for ‘Designers’ revised March 2016
Provincial qualifications are required for interior decorators/designers in Ontario who are responsible for design activities submitted with building permits. To be qualified, individuals must pass examinations from the Ministry of Municipal Affairs and Housing on building code knowledge for various categories of buildings. While not mandatory if work does not require permits, following building codes is still recommended. Insurance is also not required but is a good business strategy.

The Charity Sector in 2016 Final
This document discusses opportunities and challenges facing the charity sector in 2016. It notes that 2016 will be a year of change as new regulations and scrutiny take effect following scandals in 2015. However, it also highlights positive factors, such as thousands of volunteers continuing to donate time and money to support important causes. It argues the sector must avoid knee-jerk reactions to challenges and instead focus on leadership, transparency, and beneficiary needs. Overall the sector faces difficulties but also opportunities to innovate in responding to pressures and serving communities.

ABSTRACT
Energy wastage is one of the major challenges that is facing the world now as there is
insufficient supply of energy and the little ones supplied was not appropriately used. This
energy wastage has made many researchers to engage more on the research to stop this
energy waste as a result of inappropriate allocation of energy to some devices even when
they don’t need it. This research work was able to design and implement an improved
automated DC Motor speed controller system using microcontroller successfully. The
software used for this research work were Fritzing software and Arduino Nano. This project
was able to improve on the working system of the DC Motors and energy was automatically
and successfully saved. The system runs entirely on Bluetooth technology which consumes
less power than other devices. The Android application is user-friendly with enhanced
Wireless communication. This design was successfully developed and implemented with 80%
accuracy. The design was able to work effectively by increasing the cutting speed when the
softness of the material decreases and as the cutting tool material becomes stronger, the
cutting speed increases. This showed that the design is effectively and efficiently developed
with less energy/power consumption which is the earnest desire of an Engineer as it reduces
cost.

Power Generation Using Footstep
Abstract: We need energy for every day today work of our life. There are many conventional methods of energy generation but these are depleting very fastly hence non-conventional energy system is very essential at this time to our nation. So an alternate method of non conventional energy generation is proposed in this project. In this project we are generating electrical power as non-conventional method by simply walking or running on foot step.Here Dynamometer is used for converting mechanical energy into electrical energy. The voltage generated by this sensor is stored in battery which will be later on transmitted wirelessly to charge the mobiles.

Smart Wireless Battery Charger with Charging Monitor: A Review
This document describes a smart wireless battery charger system with charging monitoring capabilities. The system uses an AVR microcontroller to constantly measure the battery charge level and automatically charge the battery until it is fully charged, at which point charging is stopped. An electronic ballast circuit scales a 230V AC supply down to 12V AC which is sent through an air core transformer. The secondary coil induces a magnetic field that wirelessly transmits power to another coil connected to the microcontroller. The microcontroller then monitors and controls the charging process. This wireless charging system can be used to charge batteries for various devices like electric vehicles.

IRJET- Extraction of Energy from Wastage Heat Dessipation from Vehicle En...
This document proposes a system to extract energy from waste heat dissipated from a vehicle engine. It utilizes thermoelectric generators (TEGs) to directly convert the temperature difference between the engine and ambient air into electricity. The TEGs produce low voltage that is boosted by a DC-DC converter to charge a 12V lead-acid battery. The battery can then power mobile phones and LED lights. An inverter can also convert the DC power to AC. The system aims to increase engine efficiency and reduce pollution by capturing otherwise wasted heat. It has the potential to be implemented on a commercial scale to provide off-grid household electricity.

This document proposes a system to generate electricity from waste heat dissipated from a vehicle engine. It uses thermoelectric generators (TEGs) to directly convert the temperature difference between the hot engine and cooler environment into electricity. The TEGs are connected to a DC-DC converter to boost the voltage and charge a lead-acid battery. The battery can then power devices through USB ports or an inverter can convert it to AC power. This system captures otherwise wasted heat to generate useful electricity, improving engine efficiency and reducing pollution.
Advanced Electrical Drive Controls, Types and Implementation”
This document discusses types and applications of electrical drives. It begins with defining electrical drives and listing their main components in a block diagram. It then categorizes electrical drives based on supply type (AC motor drives, DC motor drives), number of motors (individual, multi-motor, group drive), speed (constant speed, variable speed), and control parameters (vector control, constant power, constant torque). Advantages include wide speed control range and efficiency while disadvantages are high initial cost and maintenance. Electrical drives have applications in industrial production, manufacturing, and process control.
