KMX’s technology facilitates a separation and recovery of pure water, lithium and other rare earth minerals a from industrial brine and waste-streams at low temperature and pressure. By using its proprietary membrane distillation technology for mineral recovery and water separation, KMX's technology targets water scarcity and contamination and offers a new method of promoting clean water and wastewater treatment. In addition, separation of Lithium, which is a critical element for batteries used in electric vehicles and other clean energy technologies, as well as other rare earth minerals, through brine and waste is a far more sustainable approach than traditional lithium extraction methods which are energy-intensive and have negative community and environmental impacts.

DepolarizingGPT is a political AI chatbot that gives three answers to every prompt: one from a left-wing perspective, one from a right-wing perspective, and a third answer from a depolarizing or "integrating" perspective. DepolarizingGPT was created by data scientist David Rozado and political philosopher Steve McIntosh. DepolarizingGPT's left-wing responses have been fine-tuned with content from left-leaning publications and writers, while its right-wing responses have been fine-tuned with content from publications and writers. The model's depolarizing responses have been fine-tuned with content from the Institute for Cultural Evolution think tank, from McIntosh's inclusive political philosophy. The model's depolarizing responses are designed to transcend centrism and reach a "higher ground" balance by exposing users to multiple views across the political spectrum.

Reef Relief Sunscreen protects people's skin while also nourishing coral reefs. The company was inspired by the dangers of chemical sunscreen ingredients to coral health, as Oxybenzone, a chemical found in 80% of sunscreens, has been proven to have a lethal effect on sea-life and can kill coral and coral larvae in even very small doses. Reef Relief's sunscreen was developed in collaboration with cosmetic chemists and marine experts to create a unique formula, containing nutrients used by coral farmers to help coral thrive. It has undergone university testing and boasts increased coral growth with their formula, and has developed the Reef Protection Factor (RPF) as a new certification for the sunscreen market.
