BasketDaN said:Spinning at their respective maximum velocities, approximately how much more energy will an ideal composite flywheel (magnetically levitated in a vaccum) be able to store than an ideal ball bearing steel alloy flywheel of the same size and shape? Thanks.
Mechanical steel flywheels use traditional mechanical components such as bearings and gears to store and release energy, while magnetic levitation composite flywheels use magnetic bearings and a composite material to achieve levitation and energy storage without any physical contact.
Magnetic levitation composite flywheels are generally more energy-efficient because they have less friction and therefore lose less energy to heat and other forms of energy loss.
There are potential safety concerns with using magnetic levitation composite flywheels, as the high-speed rotation and magnetic fields involved can be dangerous if not properly contained and controlled. However, proper safety measures can be implemented to mitigate these risks.
Mechanical steel flywheels are generally more cost-effective in terms of upfront costs, as the technology is more mature and the materials used are more readily available. However, magnetic levitation composite flywheels may offer long-term cost savings due to their energy efficiency and potential for longer lifespans.
Magnetic levitation composite flywheels have potential applications in various industries such as renewable energy, transportation, and aerospace. They can be used for energy storage, regenerative braking, and as a replacement for traditional batteries in electric vehicles and spacecraft.
