Project Build A Solar Panel: Step by step guide to building a solar panel with complete illustrations Introduction A solar cell's purpose is to generate electricity through the release of electrons from a material that is bombarded by electromagnetic radiation or photons. Most crystalline solar cells are sensitive to visible radiation from 400 - 700 nanometers, which correspond to 3.1 - 1.8 electron volts, of the visible region as shown by ACEPT W3 Group (1999) and also into the near infrared spectrum. As the wavelength of the electromagnetic radiation increases, the amount of electron volts decreases. This means that infrared radiation has less electron volts than the visible spectrum of light (because it has a larger wavelength than visible light) and ultraviolet and gamma radiation has more electron volts than both the visible spectrum of light and infrared radiation (because they have a smaller wavelength than both infrared and visible light). Significance of Solar Panels A solar cell, in itself, is of little value in our energy consumptive world.

SolTech’s Gorgeous Glass Tiles Heat Your Home With Solar Energy Alternative energy is known to be a lot of things – cutting edge, earth-friendly and forward thinking – but sadly looking pretty isn’t one of them. Well SolTech is changing all that with their gorgeous glass solar-thermal roof tiles. As if it’s not cool enough that these transparent shingles are able to heat your home by using a simple system to store energy from the sun, they also look like a million bucks!

World’s Most Efficient Solar Collector What does a Solar Collector and a Sterling Engine have in common? Well if you mention them together with a company named aptly enough – ‘Stirling Energy Systems’/ Tessera Solar you will undoubtedly be talking about the Maricopa Solar Project and their SunCatcher concentrating technology. The Sun Catcher consists of an array of curved glass mirrors arranged in a parabolic dish shape for the solar collector . In what has been claimed to be the worlds highest-ever conversion rate of 31.25%, breaking the previous record for solar collector performance. Multi-Section ‘Parabolic’ Mirror Solar Collector.

How to make a tool set Life without tools is barbaric. But even simple tools can be expensive in rural parts of developing countries. Import duties bump the costs up higher than they are in the States or elsewhere, and sometimes only low-quality brands are available anyway. So, to hold off future barbarians, we'd like to show how to build a simple tool set on a very low budget. Larry Bentley, the man who figured out how to make these tools, said a wise thing: "Without tools, kids don't take stuff apart, and without taking stuff apart, you don't learn how things work." How I built an electricity producing Solar Panel Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city slicker yuppies (you know the kind, the ones that like to blab loudly on their cell phone while they work on some business administration degree in a cyber cafe somewhere in Trendyland.) and their light pollution, I found a great piece of remote property. The problem is, it's so remote that there is no electric service available.

Appliance Efficiency and Long-Run Energy Demand Appliance Efficiency and Long-Run Energy Demand Matthew Harding (PI), David Rapson (PI) This project will examine how people make decisions about appliance purchases and the effect that these choices have on energy demand.

Survival Gardening Survival gardening can provide fresh food for you and your family in the aftermath of a disaster. Disasters can occur at anytime and anywhere, and take many forms. Not all disasters are dramatic and natural. 300w pedal generator High power Pedal generator (300 watts) 15/04/10 Click image for Hi res version This is my latest attempt at building a highly efficient powerful pedal generator. Pedalling a stationary bicycle can at times be a little tiresome therefore I wanted to make an as efficient as possible pedal generator so for every joule of energy I exert I then harvest the maximum amount of power out. Some of the pedal generators I have made in the past have been rather inefficient with a typical output of around 100 watts. This latest project has yielded 3 times that figure.

Introduction to Videos Welcome The GeorgiaStandards.Org video library is comprised of best practice videos for teachers. This video library has over one thousand videos that demonstrate effective implementation of the standards in classrooms. New battery could change world, one house at a time In a modest building on the west side of Salt Lake City, a team of specialists in advanced materials and electrochemistry has produced what could be the single most important breakthrough for clean, alternative energy since Socrates first noted solar heating 2,400 years ago. The prize is the culmination of 10 years of research and testing -- a new generation of deep-storage battery that's small enough, and safe enough, to sit in your basement and power your home. It promises to nudge the world to a paradigm shift as big as the switch from centralized mainframe computers in the 1980s to personal laptops.

9 Steps To Starting A Survival Garden In a time of economic uncertainty and rising food prices, it it always a good idea to have a garden to provide extra food for you and your family. Besides providing a source of food in an emergency, a garden is also a great source of wonderful vegetables which are MUCH healthier to eat than most of the food you can get at the supermarket. So how do you begin? How I built a solar panel for 0 – You can too Mike Davis - no hidden costs In this article I am going to describe how to build a photo voltaic solar panel for a fraction of the price you would pay a manufacturer. I’ll show you how inexpensive materials and common tools can be used to make panels that rival commercial products in power production, but blow them away on price. Several years ago I bought a remote property in Arizona.
