Video: active aero (grille block) via shape memory alloy

Really neat stuff here, directly applicable to what many of us are doing.

A GM researcher shows off shape memory alloys to Autoline Detroit TV host along with three potential automotive applications - 2 of which are active aerodynamics.

The alloys can be stretched, and return to their "memory" shape with the application of heat (or electrical current). So you can create opposing shape memory springs, and by alternately heating one or the other, move stuff (like grille louvers).

Project MPGiata! Mods for getting 50+ MPG from a 1990 Miata
Honda mods: Ecomodding my $800 Honda Fit 5-speed beater
Mitsu mods: 70 MPG in my ecomodded, dirt cheap, 3-cylinder Mirage.
