I keep toying with the idea of throwing my hat into the N-Prize ring, especially since the deadline has been extended (maybe forever?). If I do, it will be from my close association with Sugar Shot to Space and the possibility of providing a low cost reusable sugar booster to get something up to 250,000' and then let people who know what they're doing go from there since it is very unlikely that a purely sugar powered launch vehicle cannot make it into orbit no matter how many stages.
We have our first DSS grain casted and are planning our first test of the motor August 6 at the FAR test facility in the Mojave Desert of California. This will be to my knowledge, the world's largest sugar powered motor ever fired. We are all excited and strangely, may end up winning the Carmack Prize with this vehicle. I would have thought someone else would have by now or at least before we are ready. It wasn't a goal for us but now seems like we could if no one goes before us.

If Paul does put an unlimited deadline on the N-prize I will eventually do it.
