It's been a good few years for Bro inventions: There's the backpack-vacum for scaling brick walls, the Tandem-Duct Aerial Transporter, pizza vending machines, guitar-playing urinals, and a dorm room robot that throws cold beers. If you're a Bro who loves tinkering in the garage to engineering the next big invention, check out the Nissan Innovation Garage. You can submit your idea for a chance to win a $50,000 grant, a 2013 Altima, and a little help from Nissan with growing it via Kickstarter.com if it's one of two submissions chosen by Nissan's panel of engineers.
