In F1 the KERS systems fitted to some cars store kinetic energy using either batteries or flywheels and release it to provide a power boost.
What about using a variable mass fluid filled flywheel with pumped fuel as the ballast?-- Pat-O-Cake, Feb 01 2010 Be the flywheel Be_20the_20Flywheelsimilar sentiment [bungston, Feb 01 2010] For F1? Yes, why not? I don't fancy having a rapidly-spinning fuel-tank in my own car, though.-- MaxwellBuchanan, Feb 01 2010 Actually, the driver is probably the heaviest single component of an F1 car - how about using him as the flywheel? To be realistic, he'd have to rotate axially, and would probably need to drive in a prone position. The steering wheel, indicators, windscreen washers, ashtray, satnav etc would all have to rotate in synch, so perhaps what's needed is a sort of cylindrical cockpit with rotable couplings to the rest of the car.-- MaxwellBuchanan, Feb 01 2010 After ruling out the driver, the engine, and then the gearbox I opted for the fuel.
The gearbox was 2nd choice to the fuel! The diff would have been fixed in place along with the gearcage and eingine.-- Pat-O-Cake, Feb 01 2010 And KERS stands for?
Kinetic Energy Release System?-- zen_tom, Feb 02 2010 And the positive aspect of a flywheel system* could be that it stops the car from spinning.
And the negative aspect of a flywheel system* could be that it stop the car from turning.
*non contra-rotating.-- Ling, Feb 02 2010 I'm not convinced that there is enough mass. How many gallons of fuel does an F1 car carry when full?-- WcW, Feb 02 2010 Maybe more to the point: How many gallons of fuel does an F1 car carry when empty?-- Ling, Feb 02 2010 random, halfbakery
