Key Takeaways
1. Lonnie Johnson, a retired NASA engineer and inventor of the Super Soaker, aims to revolutionize electricity generation with his new project, the Johnson Thermo-Electrochemical Converter (JTEC).
2. JTEC generates electricity using water heated to only 93 °C and operates in a closed loop, utilizing hydrogen gas to create energy from various sources, including industrial waste heat.
3. The technology addresses significant energy waste in industries, with potential to capture up to 50% of lost energy as excess heat, with the first commercial unit expected in 2026.
4. Johnson’s start-up has received $30 million in funding and is expanding its engineering team, but faces challenges in reducing production costs for widespread implementation.
5. Online reactions to JTEC are mixed, with curiosity about its potential tempered by doubts regarding efficiency, costs, and competition with existing thermal power technologies.
Lonnie Johnson is a retired engineer from NASA and the Air Force, boasting over 140 patents. Many recognize the 76-year-old from Atlanta as the creator of the famous Super Soaker water guns, but he also earned a spot in the National Inventors Hall of Fame in 2022. However, with his new project, Johnson isn’t just focused on making summer more fun; he’s aiming to revolutionize electricity generation.
Innovative Energy Solution
The Johnson Thermo-Electrochemical Converter, known as JTEC, functions with very few moving parts and is designed to create electricity using water heated to only 93 °C. The system uses hydrogen gas that crosses an ultra-thin membrane because of pressure differences. As the heat raises the pressure on one side, charge carriers flow, generating electricity. Since the hydrogen isn’t used up, the process remains closed loop. This means it could capture energy from various sources, including industrial waste heat, geothermal energy, or even old boreholes.
Addressing Energy Waste
Johnson states that energy waste in industries is enormous, with as much as 50% lost as excess heat. This is precisely the kind of latent possibility that JTEC seeks to exploit. The first commercial unit is expected to be set up in 2026 at a large energy provider in the southeastern U.S., although the name of the company has not been revealed. The start-up behind this initiative has already secured $30 million in funding and has significantly grown its engineering team. However, a significant challenge still exists: production costs need to be reduced before the technology can be widely implemented.
Mixed Reactions Online
In a recent report by The Seattle Times, Johnson provided a look around his new lab in Atlanta, saying that inventing is all about “the search for good problems.” Besides JTEC, he is also working on a solid-state battery, viewing both projects as a “horse race” to see which will have a greater impact first.
Feedback on Johnson’s JTEC technology on Reddit shows a mix of feelings. While many users are curious, there is also a fair amount of doubt—largely because of the absence of solid data regarding efficiency, costs, and how this system stacks up against current thermal power technologies. Nevertheless, the report indicates that the project is being actively developed, has received financial support, and is planned for its first commercial trial in 2026. The true potential of this technology in shaping the future of energy will only be revealed once reliable performance data is provided.
