MIGHTY MITE.

In this article the author discusses the benefits of turbines that use supercritical carbon dioxide (CO₂). The author notes that the chemical properties of CO₂, such as its transition from a gas to a supercritical fluid at room temperature, make it an attractive working fluid for Brayton cycle gas turbines. Topics include the author's research as part of a team at Sandia National Laboratory in Albuquerque, New Mexico, investigating the use of Brayton cycle gas turbines for power generation, the creation of two power production supercritical CO₂ test loops at a site owned by contractor Barber Nichols Inc., and the amount of electrical power produced by Brayton cycle gas turbines compared to other power systems.
