Shark Tank The Sullivan Generator Update
- Entrepreneur: Mark Sullivan
- Business: Generator taking power from the spin of the earth
- Ask: $1 million for 10% equity
- Result: No deal
- Shark: None
Mark Sullivan entered the tank sharing with the sharks that he’s an inventor with over 1,000 inventions. However, he came to
The Sullivan Generator basically works by harnessing the spin of the earth, pulling in salt-water and preprocessing it. The water vapor is then delivered to a vortex chamber, where the Coriolis Effect spins it into a hurricane.
Then, this drives the turbines, which ultimately makes the electricity. At this point in the pitch, most of the sharks look a bit confused.
However, when Mark S. says that the mineral precipitates are manganese and gold, their ears suddenly perked up.
Robert Herjavec recaps what Mark S. shared, saying that it basically sucks water in, and spins it around really fast. From there, it essentially produces electricity on one end, and gold on the other.
Mark S. agrees with his understanding, saying that Robert is correct. The inventor then goes on to share that the gold produced could altogether total $96 billion.
He then suggests that with a partnership from a shark, they could set up 200 of the generators all over the world, adding that they’re controlled over the internet.
Mark Cuban asks Mark S. about his background is, and the inventor shares that he has degrees in bioengineering and physics.
Daymond John immediately went out, because he didn’t understand anything about the science behind the process.
Kevin O’Leary said the concept seemed to entail that Mark S. was going to create a synthetic hurricane, and eventually use it to power a 100ft machine. Mark S. confirmed that he was right about that, to the sharks’ general consternation.
Robert asked how long it would take to build the machine if an investment would be made. Mark S. said it would take nine months altogether, which ultimately made Mark Cuban go out.
Then, Kevin asked if the inventor had made any money from his other inventions, and he said that they were making over $1 billion per year, such as the left ventricular cyst device for artificial hearts.
Barbara Corcoran eventually dropped out without giving a reason.
Kevin said the project was certainly interesting, however he didn’t think it was actually legitimate. He eventually went out, followed by Robert.
It turns out that Robert had been willing to invest $50,000 , although, the offer was only there if Kevin would front the other $950,000.
With that, Mark S. had to leave the tank with his invention, but without a deal.
Did he manage to make The Sullivan Generator come to fruition, following his appearance on the show? Keep reading our Sullivan Generator update to find out more.
Our Sullivan Generator update reveals that the concept never materialized, and the science required to make it work could not be verified after all.
Mark is still an inventor with numerous patents, but the Sullivan Generator is not available for sale. That said, he maintains the Mark Sullivan Research website, which shares in detail about his many research projects and inventions, including The Sullivan Generator.
However, this will be our final update for The Sullivan Generator.
