Energy Polarizer

The Energy Polarizer is a box containing a crystal that is claimed to increase fuel efficiency. It is an example of automotive woo.

Origins
In 1986, Australian motor racing driver Peter Brock unveiled a device called an Energy Polarizer, which consisted of a black box containing a sliver of crystal surrounded by magnets, with promises it could improve the fuel performance and handling of any car which uses it. Despite no scientific testing of it, Brock claimed it worked through "aligning the molecules" of the car, and began fitting the device to all (General Motors) Holden Dealer Team specials. Other benefits claimed by the device included absorbing road shocks more completely and quietly, to reduce overall vehicle noises — both inside and outside — to achieve greater efficiency of the power train and steering systems, improving the engine and suspension performance and to create a more pleasant environment for the driver and passenger.

Failure and downfall
On the eve of the 1987 Australian Touring Car Championship, Brock was ready to release a new car called the Brock Director &mdash; a GM-based Brock car with the device as standard. With the Energy Polarizer failing to deliver any improvements in efficiency as promised, Holden refused to have anything to do with it, and after many threats from GMH to withdraw all support from Brock and the Mobile Holden Dealer team if he went ahead with the release of the car, Brock released the Brock Director in February 1987. On 23rd February 1987, Holden withdrew all support to Brock and the Brock Special Vehicles empire was gone along with his reputation.

An Energy Polarizer is also included in the modern throwbacks; however, this is just for posterity.
