Well, we have given up on the thermal engine. Progress was heading for a three-year development time. I still believe in the idea but it is not going to make it in to this competition.
The light source however is doing very well. We are going solar. I do hope New Mexico lives up to its sunny reputation on contest day. I have offered to share with other teams and will have to see what comes of it.
These are our 2006 solar cells.
