A 50% Efficient Turbine Solution

September 11, 2012 | 4 Comments

A steam turbine that drives a generator is usually only about 30% efficient.  Based on the Brayton-cycle system, developed by George Brayton more than 100 years ago, an air or steam system heats the air or water in a confined space and then releases the compressed air or steam to turn a turbine generator. The […]

A New Way to Get Power From a Nuclear Reactor

March 7, 2011 | 2 Comments

Sandia National Laboratories researchers are moving from theory and the lab bench to the demonstration phase of a new gas circulation system using supercritical CO2 for driving turbines for power generation. The theory and supporting lab work suggest that thermal-to-electric conversion efficiency will be increased to as much as 50 percent – an improvement of […]
