- I guess I've given up on electric vehicles ever becoming practical.
- So, now I am convincing myself that fly-wheel technology will be the
- next major shift in automobiles. The simple view I've taken proposes
- a small internal combustion engine running at a super-efficient, super
- clean, constant speed to "load-up" a fly-wheel to store energy. When
- you want to burn rubber, the fly-wheel is engaged to the drive wheels.
- Some pretty hefty torque and power can be tapped depending on the mass
- and rpm of the fly-wheel. Of course, regenerative braking recaptures
- some of the energy to the fly-wheel when slowing or stopping is required.
-
- In some ways, the age old challenge of maximum acceleration has a
- different twist with this technology. There can be so much stored
- energy in the fly-wheel that LIMITING its delivery to the drive wheels
- would probably be the most important factor.
-
- And I'm assuming that weight of the fly-wheel is no problem since the
- real energy will be stored by the speed at which it rotates.
-
- Any insight on what problems exist with this type of vehicle?
