while designing the flywheel wheel, i divided the design into three main parts
1)storage of energy
2)charging mechanism
3)powering mechanism( although it is almost the same as charging)
today i was focusing on storage. As mentioned in the previous blogs, we require a high rpm, low weight, and large radius. the radius in the design is as good as fixed, since its in respect to the tire. we need a really light arrangement too. so we require a really high rpm. but the problem is, the higher the rpm, the greater is the air resistance. to avoid this, we place the flywheel in a vacuum. but this poses a different problem. the flywheel inside the vacuum chamber needs to be engaged,disengaged and rotated from outside the vacuum chamber. this means that there needs to be rotational movement, as well as forward movement on the axle without breaking the vacuum seal.
before coming up with this method, i went through multiple ideas. i tried using magnets to interact (attraction) to rotate the axles without direct contact. but, this would require very strong magnets which becomes impratical.
