There are about 7 billion people living in the world today. Nearly a billion of them have access to electricity only intermittently, while another billion have no access at all. A team of UT Arlington researchers is addressing this problem head-on by developing a new power generator that can produce electricity 25 percent more efficiently than existing technology, reduce emissions, and potentially alleviate power shortages in remote areas of the world.
The device was created by aerospace engineering doctoral candidates Raheem Bello and James Peace, Professor Frank Lu, and Adjunct Instructor Dibesh Joshi. Their generator harnesses pressure gain combustion, also known as detonation.
“Up to 70 percent of energy is lost in current gas turbine combustion engine technology just because that technology hasn’t changed in several decades,” Bello says. “We capture the bulk of that energy more efficiently so it’s not wasted as heat in the body of the engine.”
The group formed the company Afthon to support the project. Their patented technology would be able to replace conventional engines in everything from cars to rockets to power plants.
“We’re looking for our generators to have the same impact on power that the cellphone had on communications for the 1.3 billion people without access to electricity,” Bello says.
Dr. Lu believes the technology has the potential to radically alter the world of energy: “This new energy technology can be a game-changer globally.”
