Mark Sullivan, a Texas-based inventor, introduced the Sullivan Generator on Shark Tank in 2012, seeking $1 million for 10% equity. The device aimed to generate electricity by harnessing Earth’s rotation and produce valuable by-products like gold.
The Sharks declined to invest, expressing skepticism about its feasibility. Since then, the Sullivan Generator has not advanced beyond the conceptual stage, with no working prototype developed.
As of 2025, there have been no significant developments or investments in the project, and it remains unrealized.
