Former NASA engineer. Current KGselr and friend of science.
Answers to some common questions:
1) I studied Mechanical Engineering in School. I did my undergrad at BYU and Masters at USC.
2) I worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover (I made a video about it you should def totes watch cause it's probably my favorite of all my videos). I founded a company called Digital Dudz on my nights and weekends while working at NASA (also made some videos about that) and sold it to the guys who make Morphsuits in the UK. As part of the sale I quit my job at NASA and worked for them coming up with all their new costume ideas for 2 years. Recently, I was presented with an opportunity to return to my Engineering roots to come do some ideation type of work for a tech company near San Francisco.

    The teacher was so passionate. Just look at him while he's explaining. He's so enthusiastic about it. My 12 grade teacher looked like he would commit suicide if I ask him a question again.

    I think a deciding factor would be to make plant based meat much more accessible. You pretty much can find meat in every corner, however plant based it's much more rare. I know you mention that you can find it in a lot of places, however I don't live in the US and it's almost impossible here to find it. Challenges would be nice as well. Hopefully some powerful people would promote this in the future.

  27. Luke Luke

    The problem comes in the fact that beyond meat/Impossible meat is insanely expensive. You compare an 8 dollar pack of Australian minced beef to an 18 dollar pack of beyond meat. It simply isn't comparable from a price efficiency perspective.

    When I looked at the title, I thought he fed Bill Gates a poisoned burger to save the world

  51. Martin Glueck

    i will never understand how delivery services just leave packages in front of the door. in germany, where i live, we either get it delivered to a locked packstation or a post office, where i can get it myself or if no ones home, the shipping company will take it back and try again a second time. if they still can't deliver it they will return it to the sender.

  52. Timothy Berner

    I'm broke as anything and have spent the last week or so working hard on my CV and applying for new jobs, had some interviews, was feeling pretty chuffed, and then... "whose qualifications include building his own electric plane from scratch." Not sure if I'm feeling inspired and amazed or totally depleted of sense of self-worth haha. Awesome video Mark!!
