If you are not one of the semifinalists, we encourage you to keep innovating and looking for opportunities to improve your idea. There were numerous, impressive submissions to the Ready! Contest. In fact, there were more than 120 submissions from across the country. Many of these were great ideas but needed additional development and refinement to advance to the next level. In the coming weeks, you will receive an e-mail from the Prize Administrator with comments and feedback on your submission from the judges that reviewed it.   

We want to thank all teams for competing in the Ready! Contest and hope you continue to be an active member of the Solar Prize community. Please continue to utilize the American-Made Network to improve your ideas and watch for other opportunities to make them a reality.
