Tree-Hugging Pedal Pushers: Innovate or Die!

Pedaling to save the world -- or at least fuel advertising -- has endless appeal because we'll probably never run out of human energy or youthful tenacity.

The idea of driving people to oblivion for not doing the right thing (Vote or die!, Funny or die!, Assimilate with Android or die!) is also insanely appealing.

So Google and Specialized give us Innovate or Die(!), a rewards-driven invitation for young engineers to invent eco-friendly, zero-emission machines that operate on human pedal power.

If you're crazy enough to do it, or need to kill time until FlugTag, make a film about it and post it on YouTube by December 15.

Prize for the most innovative submission includes $5K and a Specialized Globe bike. Five runners-up will also get Specialized Globe bikes. We don't actually know what those are.
