Solar Energy Powered Toilet for Emergency or Remote Areas Usage: Maker Movement innovation

Renewable energy is of great importance for today’s world which is generally produced from natural sources. Countries like Bangladesh has to use this energy to meet their energy demand. Day by day the demand of electricity is increasing in stormy pace but our resource is limited. So using renewable resources i.e. solar power to meet the demand of electricity is highly necessary especially rural and remote areas. This paper examined the nature and extent of solar energy in Boyarjapha village of Paikgachha Upazila of Khulna district to analyse the effects of solar panel in their daily life. Many positive impacts of solar power were found out such as better quality lighting, education, entertainment, communications, business, increasing working hours, women empowerment, increasing awareness etc. There are a few bad effects of solar energy too. But Government intervention is a must to ensure better quality results in coming future. Similarly, government has to take serious steps to advertise solar electricity in remote areas of Bangladesh

Sub Saharan Africa has a great renewable energy potential. Rural areas are suffering from poor energy access. Some systems designed to address this issue are still faced with some difficulties. Appropriate approaches and energy plant development will help remote areas to address the issue of electricity access. The current development of some micro hydro and micro solar energy plants is of poor quality and maintenance, sometimes resulting in failures. There are also some common mistakes made when promoting (designing) an energy system in an African environment. Identifying issues from local constraints and lessons learned will contribute to determining the appropriate sizing, technology and tools to correctly develop micro hydro and micro solar energy plants.

The Internet Of Things

As satellite communications provide ubiquitous coverage, they play a key role in providing Internet connectivity in remote or marginalized areas, so as to enable the vision of a truly global connectivity of the Internet of Things (IoT). However, these areas often lack reliable electricity supply. Thus, this paper proposes a satellite internet access point powered by solar energy, so that a stable Internet connection can be provided. The access point provides Wi-Fi coverage so that sensors, IoT, and devices can connect to the access point using the Wi-Fi, a common wireless technology. Our design took some cost-saving measures to make it affordable and selected the components that require minimal maintenance operations. The satellite access point costs about USD $500, and can provide four days of Internet connectivity without solar energy.

Grid Based

About 200 million people of India are deprived of grid based power supply, prominently in inaccessible hilly and rural hamlets of the country. Present research is an attempt to design, install, operate use, and maintain the hand on set of light source to address the unserved populations dwelling in electricity inaccessible areas in India. The approach is designing and developing a low cost sustainable or solar emergency light through, “Solar Home Lighting Systems” or “Sustainable Emergency Light” technology, which is one of the smart and innovative approaches of illuminating sources by harnessing solar energy to light the darkened places. The attractive daily usable gadget with surged luminous efficiency, durability, extended life, ecofriendly, compact, and efficient to work at both small values of current and voltages and they are growing acceptance. The safe and non-ignition start, is the uniqueness over conventional emergency light, and solar energy founded. The stand-alone device with mobile charging port with luminosity of 150 Lux can be used in lighting the escape routes, open areas and high risk areas. Under the crisis of pandemic of Covid-19 virus, the portable solar lights is safe and riskless light source for the economic backward classes, and can provide the children and students for online undisrupted study up to about 8 to 10 hours at low cost in remote areas.

Freshwater supply in remote areas has become a critical issue. This paper aims to introduce a new approach to a solar-powered humidification–dehumidification (HDH) desalination system. The design uses a solar collector, a thermal storage tank, and an HDH unit. The HDH works continuously by feeding water to absorb solar energy during the day and then relaying the desalination units with feed water at a top brine temperature (TBT) at night. The model predicts the amount of solar energy stored for the next day, and based on this, the amount of feed water that should be raised to the TBT is calculated. The system operation is carried out in two phases. During the day, the feed water absorbs the heat of solar energy, thereby increasing its temperature to TBT. This hot feed water is then kept in storage tanks. At night, the tank switches to discharging mode and starts feeding the HDH with the hot feed water. The system is designed so that the roles of the tank are rotated at sunset. To achieve the same TBT every day in response to changes in the available solar energy, the mass of the feed water is adjusted daily. The design is simulated using a dynamic model of the energy and mass balance resulting in an average daily production of 7.6 kg of fresh water per unit area of the solar collector. The daily average of the gain output and the recovery ratios are 0.3 and 0.09 respectively.
