The document describes two hand-cranked devices - the POWER plus Dolphin and POWER plus Shark - that can be used as flashlights and to charge mobile phones through a hand-powered generator. The Dolphin has 3 LED lights and can provide 30 minutes of light from 1 minute of cranking or make calls for 2-8 minutes from 3 minutes of cranking. The Shark is waterproof to 10 meters, has a bright LED light, and can charge phones through cranking. Both devices can also be charged through AC adapters or computers and are useful power sources in emergencies without sunlight.

Solar street Lights
Most solar panels turn on and turn off automatically by sensing outdoor light using a light source.Solar streetlights are designed to work throughout the night. Many can stay lit for more than one night if the sun is not available for a couple of days. Older models included lamps that were not fluorescent or LED. Solar lights installed in windy regions are generally equipped with flat panels to better cope with the winds.Electricity through wireless transmission witricity
1) Wireless power transmission through resonance coupling was proposed by Nikola Tesla in 1899 and experiments were conducted at MIT to transmit power without wires over short distances.
2) Witricity uses resonant inductive coupling to efficiently transfer power between two electromagnetic resonators over mid-range distances without power loss.
3) Applications of wireless power include powering consumer electronics, electric vehicles, and industrial/transportation systems without wires, helping reduce e-waste and installation costs.

Introduction to photo voltaic installation part one of two by Frederick Paris from Paris Consulting Associates
Solar power
The document discusses solar power generation, distribution, and storage from small-scale solar power systems. It describes how solar power works by converting sunlight to electricity through photovoltaic cells or concentrating solar power systems. The document outlines the components of a solar power generation system and discusses photovoltaic effect. It also addresses performance factors, applications, advantages and disadvantages of solar power.
Solar pannels 2
This document provides guidelines for a solar PV system. It discusses the components of the system including solar panels, batteries, charge controllers, inverters and meters. Solar panels convert sunlight to electricity while batteries store it for use when sunlight is unavailable. Charge controllers regulate battery charging and inverters convert DC to AC current. Meters track energy exchange with the grid through net metering. The document also covers topics like types of solar panels and batteries, system installation, maintenance, sizing considerations and mounting options.
Micro Power Stations
Micro power systems generate small amounts of electricity from sources near the point of use to eliminate transmission grids. They exploit various forms of ambient energy including solar, temperature gradients, human power, airflow, and vibrations. Research is being done on energy scavenging and storage methods like solar cells, thermoelectrics, piezoelectrics, batteries, capacitors, and miniature fuel cells to power autonomous wireless sensor nodes from scavenged energy sources in the local environment. Further development of micro power generation and ultra-low power electronics could eventually replace electrical grids by efficiently scavenging wasted and renewable energy.
Implementation of solar inverter (2)
The document discusses solar inverters for on-grid solar energy systems. It explains that solar inverters are necessary to convert the direct current (DC) output of solar panels into alternating current (AC) that can be fed into the electric grid. High efficiency and reliability are important for solar inverters in order to optimize the performance and minimize maintenance costs of solar energy systems. The document also provides an overview of grid-connected solar power systems and how excess power from such systems can be supplied to the electric grid or used to offset on-site electricity consumption.
Strato solar introduction 2011 6 30
StratoSolar proposes floating solar energy platforms at high altitudes in the stratosphere to generate reliable and inexpensive solar power. Two concepts are described: 1) A large concentrating solar power system over Northern California that would generate 1 gigawatt of power. 2) A photovoltaic system composed of modular arrays up to 1 gigawatt total that could provide weather-independent solar power to locations at latitudes up to 60 degrees. The stratosphere provides ideal conditions for solar power generation with constant strong sunlight and calm stable weather.

Lightning arresters are used to protect electrical systems from high voltage surges caused by lightning strikes. They consist of a spark gap in series with a nonlinear resistor. The resistor allows high voltages to pass to ground while preventing low voltages from causing a short circuit. Lightning arresters come in different classes depending on the voltage level they protect - station, intermediate, distribution, and secondary class arresters. They work by intercepting lightning strikes and diverting the high current to ground to limit the voltage in the protected system. Common applications include protecting tall buildings, power lines, and electrical devices in homes and businesses.
Solar energy and wind turbine
Solar and wind energy are important renewable energy sources. Solar energy harnesses the sun's radiant light and heat, with the amount of solar energy received by the Earth being twice as much as the total energy produced from non-renewable sources. Wind energy uses wind turbines to convert the kinetic energy of wind into mechanical or electrical energy. Both solar and wind energy have advantages such as being clean, abundant sources that do not produce pollution, but also have disadvantages like high upfront costs and unreliable availability depending on sunlight or wind conditions.

Final Copy of Letter to Pastor Donovan
The document is a proposal from John Greyling to Pastor Donovan about providing solar-powered lamps called Genie Lamps to underserved communities in South Africa and Africa. The lamps were designed to provide safe, affordable lighting to replace candles and paraffin lamps. They can also charge mobile phones. Over 5,000 school children in South Africa were found to study by candlelight alone. The lamps last 10-12 hours on an 8 hour solar charge and cost about $90 each including accessories. Greyling believes the pastor can help distribute the lamps to improve lives and sees it as a way to ensure donation funds go directly to those in need.
