Former NASA engineer. Current ESselsr 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.

    Well why is there no such "plant"-based meat in stores yet, if it's so much more efficient and cheaper, genius? I'm all up for the idea, but i bet it would cost at least five times the regular meat price, not to mention how long would it take to spread idea across every major continent AND to make the old factories start producing the new thing when they already making fortune on real meat.

    Need to feed bill gates? Just give him a gold plated veggie burger


    It all makes perfect sense. Just don't lobby and support politicians to force behavior change. Allow competition, innovation and free markets to ring.... The price of (beef) meat will go up and the price of plant based food will drop if the truth is being told. The Gov should be completely out of your decision and out of subsidizing the production of any food. I have a great idea.....If you want to help the environment just eat less, period. God Speed
