Energy Efficiency of Lightning Leah Holleman Brooke Perry APES Pd: 1st What are its main goals? • To provide adequate energy from a natural source • To not harm the Earth with unintended effects http://www.personal-computer-services.co.uk/Images/lightning.jpg What is its overall potential in “making a difference”? • It is a free source and can be sold for much cheaper than current market energy • Lightning strikes the earth 100 times per second, so there is a huge channel of energy always flowing from Earth • One storm can discharge enough energy to supply the entire U.S. with electricity for 20 minutes How does it work? http://images.machinedesign.com/images/archi ve/70867whenlightn_00000047536.jpg • A prototype collects power from ground area during a strike • Converted into electricity and sold through existing power grids • Mobile “lightning farm” • A lightning bolt carries one million kilowatts of electrical energy What technological obstacles might disrupt/stall mass implementation? • Strikes random, inconsistent and highly unpredictable, thus difficult to set up lightning power system • Little research fully completed • Uses energy at once, requiring huge batteries and capacitors at facilities • Powerful that it could easily overload all but the most sophisticated and heavy-duty systems What political/economical obstacles might disrupt/stall mass implementation? • Huge cost factor, even only considering the research • Federal budgets for alternative energy sources http://www.miqel.com/images_1/reading_ library/lightning-shaman.jpg What are some of the negative environmental impacts? • There are few, if any, because lightning itself is a natural occurrence of the Earth • Possibilities are: 1. an explosion 2. striking a fire 3. large portion of land used for lightning farms http://www.stormscapesdarwin.com/use rimages/swaw06_lightning.jpg Bibliography • http://www.treehugger.com/fi les/2006/10/alternative_ene _2.php • http://www.greenideal.com/a lternative-energy/canlightning-be-harnessed-asan-energy-source/ • http://www.wisegeek.com/ca n-we-store-electricity-fromlightning.htm • http://www.nasa.gov/images/ content/150599main_lightni ng_photo.jpg (background photo) http://lib.store.yahoo.net/lib/discoverthis/lightning-laba.gif
