Need a Science Fair Experiment? Always wanting to try this, here are the results of my experiment. For more on electricity old theories and new ones, visit: amasci.com for the answers. You can do the same. Note:. I used random parts and tried to keep the LED values low, with what I had on hand. Transistors are like electronic (one way) valves. The center leg controls the opening and closing or amplification of the valve. Using only that part of a PNP transistor, I devised my own diode for this experiment. Transistors replaced vacuum tubes. They are used mostly 2 ways. To amplify the signal passing through, or to act as an “electronic switch”. Current only goes through one way, and by increasing or decreasing the bias current on the center leg, you can control the flow though it. In most cases, adding even higher voltage, increases the output, thus making it an amplifier. Diodes allow electricity to go only one way, which makes a great gate. DC electricity’s electrons always flow from Negative to Positive. Same as Earth’s Negative electrons flying to a positive charge in the sky. AKA lightning. Yes, it is a scientific fact. Ask Ben Franklin!. Thanks for watching and keep using your heads. Dave
Billy Schopf, a sixth-grader at Whitehall-Coplay Middle School, is the inaugural winner of the Da Vinci Science Center Science Hall of Fame’s Young Scientist Award. Billy has developed a patent-pending wind-powered generating system for solar and electric vehicles. Billys device features turbine-style blades affixed to the front of a vehicle. The blades twist uwind power generate maximum wind power for any electric cars generator in the same manner that a wind turbine powers a buildings electrical grid. What makes Billys system an unexpected success is both its ability to produce electricity during the day and at night and its ability to generate electricity at any wind speed. What makes Billys system unique is its use of a thixotropic fluid to control the angles of the turbine blades in order to maximize their output.
If you dream is to make a wind power generator for your science project or for use to power your home in order to live off the grid, this piece of article will be of assistant to you. You might have heard about this and you are yet to believe it, but I tell you it is possible for you to make your own wind generator to power your home using your two hands. Another good part of building your own wind power generator is that you will be able to save a huge amount of cash if you do this on your own rather than buying one from a wholesaler or retailer, or even seeking the service of a professional installer to fix it in your own for you. Once you have the guides and directions at your reach, you will be able to easily build your wind generator in no time. With the help of used auto components, ends, odd and general supplies from your nearest community local hardware center, you will be building the wind generator in an affordable manner.
By now you must be contemplating about whether to build your own wind generator or to purchase one from a nearby shop. I must tell you that commercial-made wind generators will require thousands of dollars to get, unlike just $250 which you need to get the materials to build yours. The parts required to build the wind generator, such as batteries, DC motor, hub, and towers are very affordable, not expensive. You can build a wind generator for under $250 and you will be able to gain back the money you invested into within a year, which makes it better than having to purchase a professional installed commercial one. If your plans are to use good quality parts to build the wind generator, you are going to see that the overall cost is far better than a professional built and installed one. This also applies to students that want to build wind generator for a science prowind powerng>.
Power produced from the wind is still one of the best known cheap and effective ways to utilize renewable energy. Many homes in the USA and beyond now use wind power for their day to day energy requirement, and the most amazing thing is that most homes build theirs. You will not be lost in the crowd if you intend to build yours starting from today. You can easily own a green power supply if you put in a little effort to make one starting from today. You won’t only be saving our earth from global warm, but you would also save much money too.
You won’t find it difficult to build your own wind generator. An average person can use a Do It Yourself manual with detailed instructions. It’s left for you to build your own wind generator starting from now and fix it to your roof to enjoy the free gift of nature.
Earth 4 Energy is a DIY manual which consists of videos and guides which you can easily use to build your own solar panel from home for under $200. If you want to live off the grid, now is your opportunity to build yours for less than the price of commercially made ones.

April 26, 2010 Science at the Theater: Learn about three efforts our grandchildren may thank us for: cheap solar energy, bringing energy efficiency to China, and learning how to store carbon deep underground. Can solar energy be dirt cheap? We’re all potentially billionaires when it comes to solar energy. The trick is learning how to convert sunlight to electricity using cheap and plentiful materials. Ramamoorthy Ramesh, an innovative materials scientist at Berkeley Lab, will discuss how he and other researchers are working to make photovoltaic cells using the most abundant elements in the Earth’s crust — materials that are literally as common as dirt. Energy efficiency in China Nan Zhou is a researcher with Berkeley Labs China Energy Group. She will speak about Chinas energy use and the policies that have been implemented to increase energy efficiency and reduce CO2 emission growth. Her work focuses on building China’s capacity to evaluate, adopt and implement low-carbon development strategies. Zhou has an architecture degree from China, and a Master and Ph.D. in Engineering from Japan. Understanding geologic carbon sequestration Even with continued growth of renewable energy sources such as wind and solar, fossil fuels will likely remain cheap and plentiful for decades to come. Geologist Curt Oldenburg, who heads Berkeley Lab’s Geologic Carbon Sequestration Program, will discuss a strategy to reduce carbon emissions from coal and natural gas. It involves pumping …
