In case you forgot, the X Prize Foundation put together a pre-contest contest this past fall. That is, they challenged people to decide what kind of green invention would be worthy of the next $10 million X Prize, and present their proposals in the form of a 2 minute Youtube video. The winners would get $25,000 for their idea, plus the satisfaction of knowing that there would be a whole bunch of X-Prize hungry inventors out there trying to make it a reality.
And the winner is? Ultracapacitors. In their video, a group of students from UC Irvine, led by one Kyle Good, basically said – build a really good ultracapacitor. To reiterate their conditions:
- You may only use self-contained capacitors
- You must exceed the energy density of a lead-acid battery
- The device must recharge in less than a minute and survive half a million cycles
- You must use non-toxic, recyclable materials
- The device must cost less than 2x the cost of a lead-acid battery.
- The device must hold enough power to drive an electric vehicle for 100 miles per charge
And now… we wait. This is the fifth challenge to come out of the X-Prize foundation since 2004, and so far only one of them was met – the team that built a private spaceship in 2004. Granted, lofty goals are what this prize is all about. And if this one becomes a reality, it would be incredibly awesome.
