Adding more engineering courses

I would like to see Khan Academy add courses in mechanical, chemical, and civil engineering. Would anyone else like to see this? Over the years there have been a couple of posts asking about more engineering courses. Since Khan Academy has helped many people learn, maybe adding some more engineering courses could help students learn better, and also maybe it could help more high school students to decide if engineering is right for them. Also it is my understanding that the electrical engineering course on here is a basic course. Similarly any additional engineering courses don't have to be more advanced than necessary. They could just give people an idea of what goes into engineering.
