- yowzadave 4y agoIf only the lego gears (and your arm) could withstand the force required to turn that crank!
- ajsnigrutin 4y agoI'm sure there is a physics professor somewhere just typing a homework for students to calculate the required turning speed for the last wheel to reach lightspeed on the outer edge and what kind of energy would be needed to spin all those wheels up (ignoring any friction, etc.) :)

- vitiral 4y agoI think theoretically this machine would work in reverse. Relativistically this is not the case.
- jagged-chisel 4y agoAlso realistically. Lego are not designed to deal with the stress required.
- xwdv 4y agoPretty sure if that was possible the resulting transfer of energy would destroy the entire universe.
