Useful
- 1 inch (in) = 2.54 centimeters (cm)
- 1 foot (ft) = 0.3084 meters (m)
- 1 cubic inch (in³) = 16.39 milliliters (mL) = 1.639 * 10^-5 cubic meters (m³)
- 1 milliamp-hour = 3.6 Coulombs
- 1 amp-hour = 3600 Coulombs
Fun
- 2000 Calories (kCal) = 2.324 kilowatt-hours (kWh)
- 100 Calories per 2 Tablespoons (kCal/Tbsp) = 3,930 watt-hours per liter (Wh/L)
- Energy of a neodymium magnet at 1.5 Tesla (T)
- (1.5 Tesla)^2/(2*4pi*10^-7 Henries per meter) * (1.639 * 10^-5 cubic meters) = 14.67 Newton-meters (Nm) in a cubic inch
- Conclusion: A cubic inch neomagnet, if depleted of its magnetic energy, could not even run a 15 watt light bulb for one second.
- Energy of a AA Battery (7.7 mL) at 1.5 Volts (V) and 2000 milliamp-hours (mAh)...
- (1.5 Volts * 7200 Coulombs) * (16.39 ml / 7.7 mL) = 22,990 Newton-meters (Nm) in a cubic inch (> 1,500x)
- Conclusion: The magnetic field energy of a magnet, if depleted, would yield less than 0.1% as much energy as a battery of the same size.
- Energy of Peanut Butter at 100 Calories per 2 Tablespoons
- (3,930 Wh/L) * (3600 Nm/Wh) * (0.01639 L) = 231,900 Newton-meters (Nm) in a cubic inch (> 15,000x)
- Conclusion: Food sources of energy can be substantially more energy dense than typical battery tech.
- Energy of a neodymium magnet at 1.5 Tesla (T)
