How Solar Energy Is Converted To Electricity Through Solar Panels
Sunlight is made up of tiny packets of energy, called photons. Every minute, enough of this energy reaches the earth to meet the world's energy demand for a whole year. Photovoltaic panels consists of many solar cells, these are materials made like silicon, one of the most common elements on earth. The individual cell is designed with a positive and a negative layer to create an electric field, just like in the battery. As photons are absorb in the cell, their energy causes electrons to come free. The electrons move towards the bottom of the cell, and exit through the connecting wire. This flow of.
Kickstarter ReadySet Solar Kit for iPad, iPhone, Android more
Hi! My name is Mike Lin. And I'm Brian Warshawsky. And we run Fenix International, a San Franciscobased startup, where we make renewable energy products for emerging markets. Our first product, the ReadySet, is a renewable energy system that can be charged from solar panels, bicycle generators, or even grid electricity. An estimated 1.5 billion live off the grid, without access to electricity. Incredibly, 600 million use cell phones even while lacking the power to keep their phones charged. They also burn kerosene for lighting, which is dirty, dangerous, and expensive.
We designed the ReadySet to make it easy to start an offgrid phone charging business, as well as provide clean and safe electric lighting. I was able to collect 100,000 from the charging of people's phones last month. Since we launched the ReadySet in Africa, many of our friends have been asking us, when they'll be available here in the US. We're happy to announce, the time is now. While we designed the ReadySet for the developing world, there are just as many applications for the ReadySet here at home. Each ReadySet Kit includes a 15 Watt solar panel,.
A grid charger, an LED light, and a universal clip charger, that can charge lithium ion batteries for nearly any camera or cell phone. We built the ReadySet to power countless devices, from its 2 USB ports and 2 car lighter adaptor ports. You can use the ReadySet to create a lowcarbon digital lifestyle, by powering your iPad, iphone, or Android devices with solar power. If you like the outdoors, you can use the ReadySet to power your campsite, by running lights, speakers, and other devices while you're off the grid.
In case of an emergency, like an earthquake, hurricane, or snow storm, the ReadySet can provide vital backup power for communications, flashlights, portable radios, and even a wifi hotspot. These applications are just the start. We've designed the ReadySet with an open standard input to enable users to design their own sources of power generation, like a microwind turbine our interns designed last summer. We're publishing a power API, and launching an online platform to allow makers and hackers to collaborate and to develop new hardware applications for the ReadySet. Together, we can create ReadySet applications that are useful here at home,.
And hopefully power sustainable development in emerging markets as well. So Kickstarter, here's what we need from you. In order for us to bring the ReadySet to the US and support our developer community, we need 100 of you to buy a ReadySet now. By funding our Kickstarter, you can show your support for renewable energy, and help us in our mission to deliver power to the 1.5 billion people who live without electricity. Check back here for new tutorials and updates, and help us spread the word. Thank you very much for your support.
Renewable Energy Education Kit FCJJ 37 Horizon Educational
The Renewable Energy Education Kit is the best way to explore many different forms of renewable energy without having to buy lots of lab equipment. The Renewable Energy Education Kit can generate electricity using a wind turbine, solar panel, or one of two hydrogen fuel cells. The electric current can be used to power a small fan or light up LEDs. The solar cell converts light from the Sun, or a normal desk lamp if it's cloudy, into electricity. The wind turbine generates electricity using the wind outside or the power of a desktop fan.
Its blades are easily interchangeable, allowing for hundreds of different configurations with three sets of three types of blades, each adjustable to three different angles. The Renewable Energy Education Kit also contains two fuel cells a reversible one that uses distilled water, and one that uses pure hydrogen and oxygen from the air. After being filled with distilled water, the reversible fuel cell can use an electric current to split that water into hydrogen and oxygen, storing them safely in two cylinders. The wind turbine can be used to provide that current, or the included battery pack.
Milliliter markings on the sides of the cylinders let students measure how much gas is being produced by observing the displacement of the water. Once enough hydrogen has been collected, the fuel cell can work in reverse to generate electricity by recombining the hydrogen and oxygen from the cylinders. The smaller fuel cell takes oxygen directly from the air and combines it with hydrogen gas. Using the variable resistor, the amount of current in the circuit can be altered on the fly. And the circuit board module allows multiple energy sources to be attached to the same circuit.
The Renewable Energy Monitor, sold separately, can be used to gather realtime data such as volts, amps, and more. And our Energy Monitor Software allows you to create graphs while performing experiments with the Renewable Energy Education Kit. And as with our other great science kits, with the Renewable Energy Education Kit you'll get access to our premium curriculum content, online at horizoncurriculum when you purchase through one of our exclusive resellers. Activities are available for middle and high school students in physics, chemistry, and earth science, with each one aligned to Next Generation Science Standards, the Energy Literacy.
