Gas Letdown Generator

The Langson Energy’s Gas Letdown Generator™ generates Green Power from wasted gas pressure at People’s Gas pipeline in Chicago, Illinois. For the first time, on July 23, 2014, testing was completed on a USA gas distribution system using Langson Energy’s award winning Gas Letdown Generator™. The system performed beyond expectations by generating more power at higher efficiencies than predicted. This testing proved beyond a doubt that the technology works, is safe and economical. The tests were attended by many engineers, including David Lazzaro, General Manager of People’s Gas and Bill Lynes of RL Dent Resources. The significance of this test is that gigawatts of extremely low-cost electricity can be generated close to the consumer by utilizing wasted kinetic energy in millions of pressure reduction valves found in the gas pipelines and factories through the USA and the world.

Langson Energy’s founder, Richard Langson, said, “It’s very satisfying to have the first Gas Letdown Generator running on a major gas company grid in the USA. We are pleased that the machine logged thousands of test data points and proved to out-perform even our projections.” Personnel from People’s Gas were also excited by the side-benefit of valuable cooling created from the pressure reduction that could also be utilized by customers to further reduce their cost of power.

The Gas Letdown Generator™ is an innovative technology that harnesses wasted energy from pressure reduction on gas pipelines to produce low cost, baseload, clean, low-cost electricity. A significant benefit can also be the optional use of cooling for customer needs. Because the Gas Letdown Generator™ uses no fossil fuels to operate, it serves to improve the energy efficiency of existing facilities and industry.

Langson Energy has developed a line of Steam and Gas Generators from 250 kW to 5MW, which use no fuel – only wasted steam, heat and gas pressure.


About Langson Energy Incorporated
Langson Energy of Carson City, Nevada has developed exceptionally efficient and unique power conversion systems called the Steam Machines and Gas Letdown Generators. These machines convert Steam, Gas Pressure and Waste Heat to Green Power more cost effectively than all other forms of power generation. This technology easily handles challenges encountered by previous attempts to harness wasted energy from pressure reduction and saturated steam. This technology makes clean power by integrating LEI technology with off the-shelf components that have a proven history of reliable, robust, low-maintenance performance.
