About Horne Technologies

Horne Technologies is a private company focused on developing a practical and scalable solution for clean energy through nuclear fusion. Founded in 2008 by Tanner Horne, who also serves as the CEO, the company is headquartered in Louisville, Colorado.

The company is engineering a unique hybrid fusion reactor that combines two proven confinement methods: Inertial Electrostatic Confinement (IEC) and magnetic confinement. This dual approach utilizes a superconducting, magnetically-shielded grid, a high-beta capable fusion core, and inertial electrostatic heating to create a non-thermal fusion process. This design aims to overcome the limitations of traditional fusion methods, operate continuously, and avoid the immense energy requirements and radioactive materials associated with other approaches. The company's first-generation prototype produced its first plasma in 2017, and a second-generation device is under construction to gather data for achieving net energy gain.

Horne Technologies' business model is centered on the research and development of this fusion technology, with the ultimate goal of commercialization for both terrestrial and space applications. The company has received financial support from investors including Free Radical Ventures, Aspect Holdings, and Cottonwood Technology Fund. By focusing on an engineering-first strategy with rapid prototyping and using abundant deuterium as a fuel source, Horne Technologies aims to de-risk its path to market and deliver modular, decentralized, and cost-effective fusion energy.
