Topic: Mario Kart 8's official Steering wheel conserves battery?

Argos claims that the new Wheel can save battery power by pressing a button on the back of the wheel.I wonder how it can save battery since the attachment is made completely out of some kind of Plastic as far as I know.Got any theories on how it could help save power.I use Wiimote recharge packs instead of real batteries so maybe this feature won't work with my battery packs.But anyway I still wonder how such a feature can work.No other website I've seen has made this claim.

Because the special plastic they use produces electricity as you touches them.

Because of the hidden battery pack that uses cold fusion to to produce electricity

Probably the matrix generator which materializes your kart. Pressing the button will switch it to standby.

Actually got my hands on the New MK8 Wheel and there is no button present on the back of the wheel that apparently can save battery.Just a button that presses the B button in like the original Wii Wheel.Still wonder why Argos claimed such a thing.Never mind all is answered.
