Welcome to the 218th episode of the Inc. Uncensored podcast, hosted by Inc.'s editor in chief, James Ledbetter

First, I chat about Carbon Engineering, a Canadian startup that just might be the world's best chance to reverse global warming. The company uses some pretty advanced science--and some enormous fans--to suck carbon dioxide from the atmosphere and turn it into fuel with no carbon footprint.

Staff writer Emily Canal discusses SynDaver, a company that makes shockingly realistic synthetic cadavers for medical schools and movie sets. (If you don't need a whole body, which sells for $70,000, you can buy just a head for $5,000.) The products are reusable and come in animal versions for veterinarians-in-training. 

Finally, assistant editor Cameron Albert-Deitch talks about Cameo, the aptly named startup that allows users to pay celebrities to record messages for friends or loved ones. The company has completed more than 200,000 bookings, with talent ranging from pro athletes to YouTube stars.
