As I said, I'm fully aware of BrLP's checkered past with many broken promises of commercialization. As a result, I was extremely skeptical this time around as well and ready to dismiss the SunCell out of hand. But when I looked into it, I saw a maturity to the design and reputable partners who I very much doubt would want to be associated with a sketchy project. Most of the engineering and fab of the prototype is being done by Columbia Tech which has a good reputation in the industry. I think there will be delays, but if the claims have validity, this could be a big deal. If not, it costs little to follow this for a while.
