And how long you are going to provide energy. You can use a sound card oscilloscope with your computer\/laptop to measure and record the voltage over time. Take the readings each second and add them up.<\/p>\n<p>EnergyJoulesForOneSecond = PowerWattsForOneSecond * 1 second<\/p>\n<p>PowerWatts = CurrentAmperes * VoltageVolts<\/p>\n<p>EnergyJoules = PowerWatts* TimeSeconds<\/p>\n<p>VoltageVolts = CurrentAmperes * ResistanceOhms<\/p>\n<p>PowerWatts = ResistanceOhms * CurrentAmperes^2<\/p>\n<p>PowerWatts = VoltageVolts^2\/ResistanceOhms<\/p>\n<p>I think that is 66 foot electrical tape at 3\/4 inch wide and weight 90.7 grams or 0.0907 Kilograms. The radius is something close to 2.5 centimeters or 0.025 meters.<\/p>\n<p>The MomentOfInertia is close to (1\/2)*(0.0907 kg) * (0.025 meters)^2 = 0.00002834375 KilogramMeterSquared<\/p>\n<p>EnergyJoules = (1\/2) * (2 pi)^2 * MomentOfInertia * FrequencyHertz^2<\/p>\n<p>EnergyJoules = EnergyWattSeconds = 5.59483*10^-4 WattSecondsPerHertzSquared * FrequencyHertz^2<\/p>\n<p>EnergyWattSeconds = 0.5595 * F^2 in milliWattSeconds<\/p>\n<p>1000 RevolutionsPerMinute = 1000\/60 RevolutionsPerSecond = 16.667 Rps = 16.667 Hertz<\/p>\n<p>EnergyWattSeconds = 0.5595 * (16.667 Hertz)^2 = 155.4 milliWatt seconds.<\/p>\n<p>If you power something that need 1 milliWatt, it will last about 155 seconds, except the power drops off fast and it will only work for a shorter time at that power level.<\/p>\n<p>It seems like a lot to remember, but put it into a spreadsheet and you don&#8217;t have to remember all the details, just get them right when you set it up. There are going to be flywheel groups all over the Internet, and many many many calculators, models, equations and estimates.<\/p>\n<p>Here is something more specific to storing energy at <a href=\"https:\/\/en.wikipedia.org\/wiki\/Flywheel_energy_storage\">https:\/\/en.wikipedia.org\/wiki\/Flywheel_energy_storage<\/a><\/p>\n<p>While electrical energy is useful, you might want to consider its use for storing angular momentum that can be used directly &#8212; <a href=\"https:\/\/en.wikipedia.org\/wiki\/Control_moment_gyroscope\">https:\/\/en.wikipedia.org\/wiki\/Control_moment_gyroscope<\/a><\/p>\n<p>Sincerely,<br \/>\nRichard Collins, Director, The Internet Foundation<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Electrical tests! | 2 Mechanical Battery by Black Sahara at https:\/\/www.youtube.com\/watch?v=uiOf_-0aFP8 I like what you are doing or I would not comment.
