Re: Monocoque - my entry cited that format to give additional strength to the chassis/panels mating. Bio-composites are approaching the tensile strength of carbon fiber, and could potentially be much easier to mass produce and at a lower price point. I thought the implication that in 10 years, with research, such an avenue would be viable. Instead, the second place entry was some proprietary kind of new metal that could be used to replace body panels...that's it. I remember calling that entry a "body kit" because that's what it reminded me of overall.
I tuned in to every Q&A session provided during the contest and time and again they reiterated certain principles for judging...when the results came in, yeah, pretty infuriating. Oh well...it did motivate me to finally meet with a Patent Attorney on a couple other ideas, so some lemonade did come out of it.
