First, they get the university to publish an article making their claim seem credible.
They then get an investor to give them $300,000 and make a custom order with a factory in China to add another piece of plastic and some branding to an existing device.
They wait 3 months and then receive 30,000 "magic" gizmos in the mail.
Then, they sell people a $250 electric muscle stimulator that you wear while sitting.
Then they buy a really big new house. They live in a city in the United States though so after taxes and paying a few other people off, it barely even qualifies as a mansion.
Probably aiming for something like this one https://www.zillow.com/homedetails/6503-Edloe-St-Houston-TX-... which is very nice, but his country club friends who are really rich will compare it to their guest houses.
Fortunately they are almost done with the $59.99 app that tracks how much fat you are supposedly burning while you sit there for hours and your calfs twitch.
I think this will sell very, very well. People are incredibly lazy and want to believe that not only do they not need to get off their fat ass, they don't need to move anything other than their feet and legs a few inches. Not only that, they don't even need the willpower to move on their own, and in fact it only works if they plug in to a device that does everything for them. Lol.
