Charm co-founder here... Two quick notes:

(1) we agree wholeheartedly on the experts front — for the core technology around gasification we've been working with a variety of PhDs, national labs and companies with extensive previous gasification experience,

(2) the gasification technology we're developing is actually fairly novel and unfortunately in this industry that means patenting is in our future, which means that we're not going to blog about the core parts of our gasification system... instead we can blog about the surrounding systems that still represent interesting challenges. So that's why we blogged about grass flow. Rest assured 95% of our time is going into gasification ;)
