Now here's a green challenge with some serious incentive--but you'll have to act fast because entries need to be in by the 30th of this month. The Dutch Postcode Lottery and PICNIC present the PICNIC Green Challenge, a call for truly innovative greenhouse-gas-reducing products and services.

Whoever comes up with the best idea will be awarded with a slammin' EUR500,000 (nearly $685,000)! In addition, the winner will receive coaching and a base list of customers to help get their plan up and running within two years.
