Zap Energy hits 37-million-degree electron temperatures in compact fusion device
Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

Jeff Guldner leads Pinnacle West Capital Corporation and its primary subsidiary, Arizona Public Service Company (APS). The companies are headquartered in Phoenix.
APS employs more than 6,000 people and serves nearly 1.3 million customers across Arizona. The company is among the nation’s top utilities for delivering clean and reliable energy to its customers and has announced an ambitious commitment to deliver 100% clean, carbon-free electricity to customers by 2050. APS operates the Palo Verde Generating Station, the nation’s largest energy producer—all of it carbon-free, and ranks among the top five investor-owned utilities for solar energy capacity.
Guldner was promoted to his current position in November 2019 from his dual roles as president of APS and executive vice president, public policy of Pinnacle West. Since joining APS in 2004, Guldner has held a number of leadership positions responsible for areas including legal, rates and regulation, government affairs and customer service.
Prior to APS, Guldner was a partner in the Phoenix office of Snell & Wilmer LLP, where he practiced public utility, telecommunications and energy law. Before practicing law, Guldner served as a surface warfare officer in the United States Navy and was an assistant professor of naval history at the University of Washington.
Guldner is dedicated to community involvement and actively serves on boards of directors, including the Partnership for Economic Innovation, the National Association of Manufacturers, Arizona Theatre Company and Greater Phoenix Economic Council, where he currently serves as Chair.
He earned a Bachelor of Arts degree from the University of Iowa and graduated magna cum laude from the Arizona State University College of Law. Guldner also completed the Reactor Technology Course at the Massachusetts Institute of Technology and the Advanced Management Program at Columbia Business School.
