AUDI A2 ELECTRIC CONCEPT REVEALED, INVOLVES LASERS, LEDs AND MICROREFLECTORS

Lasers make everything better, including (but not limited to): microphones, kidneys and Audi's electric A2 concept. This newest flight of fancy uses a laser diode as the rear fog lamp, which projects a red triangle onto the road to let other drivers know you're there. The German car-maker has tricked out the rest of the EV's lighting system as well by implementing matrix beam technology using LEDs and microreflectors -- giving it high resolution, non-glaring beams and intelligent tail lights that change in intensity based on weather conditions. Claiming other state-of-the-art features like gesture controls instead of keys, and brake lights that glow brighter the harder you press, it sounds like this would be a pretty sweet ride -- if it ever makes it to market. No word on the other, insignificant details, like what actually powers the thing.

REDEMPTION CREDIT CARD ALLOWS YOU TO CHOOSE CREDIT OR REWARDS

The Redemption credit card allows the user to use either credit or rewards points to pay for their purchase.  The card was developed by Dynamics and is currently being tested by Citi.  When the user goes to pay for a purchase, they press the side of the card they wish to use, Credit or Rewards, and an LED lights up to indicate the choice.  The purchase is then processed using the selection.  No word on if purchases can be split between the two.  There are also questions about how long the LED and battery will last and how durable the touch sensors for the selections are.
