The X Prize Foundation is at it again, this time with a new eco-challenge offering $25,000 for the best “crazy green idea” to stop global warming, reports CNET. The organization, famous for its high-stakes engineering contests, is looking for breakthrough ideas in energy and housing. Proposals must be presented in two-minute concept videos, and posted on YouTube by October 31.
The contest, smaller in stakes than other X Prize projects, aims to generate the seed idea for the foundation's upcoming, big-money Energy and Environment Challenge. Other X Prize endeavors include the $30-million Google Lunar X Prize for a rock-surfing moon vehicle and a $10-million contest for an energy-efficient auto.
