The Infinity Cell Kickstarter project is the perfect invention for people whose phones die at inopportune times, which is pretty much every smartphone owner at one time or another.
The Infinity Cell uses kinetic energy that is generated when you move around, which then transfers that energy to your smartphone's internal battery. That means that the Infinity Cell is a smartphone charging solution that doesn't involve pesky things like wall outlets or cables. Simply slide the iPhone into the cradle and your movement will handle the rest. The Infinity Cell even comes with an app to show you how much energy and carbon emissions you've saved by using the device, as well as games to play around with the kinetic energy you've stored.
The Kickstarter project has a stated goal of $155,000, so I think if anyone who has ever had their smartphone die at the worst possible time gave 10 cents, they'd hit their goal by lunchtime tomorrow.
