Accelerating the transition to sustainable transportation through power-generating suspension systems.
About us
Jon Hurry, one of our founders, was first captivated by the potential of harnessing naturally occurring energy from vehicles traveling over road displacements during his participation in his university's solar electric race competition in the early 90s. Unlike typical shocks that dissipate energy, there was a tremendous opportunity to capture usable energy by leveraging a power-generating suspension system. However, at the time, the technology was too expensive and inefficient to be commercially viable.
Since then, the market has evolved, with an increasing demand for electric vehicle range and emissions reduction. Furthermore, Jon discovered new advances in linear generator technology that made the idea more appealing and feasible.
Propitious Technologies was established in 2019 by Jon and Elsbeth Hurry, who shared a passion for developing green technology solutions to meet the world's energy needs. The company assembled a world-class team that worked in collaboration with Tufts University, Dr. John Miller, Dr. James Kirtley, Abtery AB, and others. The team experimented with different designs and materials to refine their technology, ultimately leading to a differentiated (patents pending) value proposition for refrigerated trailers, electric semis, and containers. Their testing of the prototype designs yielded remarkable results, revealing a breakthrough in linear generator design that allowed them to create a highly efficient linear generator capable of capturing a significant amount of energy based on variable road inputs experienced when driving on rough roads. As such, Propitious' technology has the potential to revolutionize the market and accelerate the transition to more sustainable transportation.
In early 2023, Johan de Nysschen, a world-class CEO with extensive experience and leadership in the automotive segment, was added to the team to lead commercialization efforts. With enormous potential, the company is finalizing the funding needed to prove the technology in the real world.
Propitious Technologies is emerging as a leading player in the clean-tech industry, recognized for its innovative solutions that address the world's energy needs. The company's commitment to sustainability and passion for innovation make it a driving force in the transition to a cleaner, more sustainable future.

Overview
The Issue
More than 90 percent of food consumed in America is transported in refrigerated shipping trailers. These “reefers” are one of the largest vehicle polluters in America. They often require a secondary diesel generator, which are lightly regulated and produce tons of particulate emissions – spewing forth 22.5 pounds of CO2 per gallon of diesel fuel burned. Could this refrigeration be managed using a cleaner approach?
every year
tons of greenhouse gases (CO2) are added globally
every year vehicles alone release over
tons of greenhouse gases into our atmosphere 16% WW, 29% US
by 2040
growth in transportation emissions is expected
are needed to absorb CO2 produced by 1 semi-truck in a year
The Technology
Propitious has developed an innovative, patent-pending power generating suspension system (“PGSS”) mated to an electric generator to cool the refrigeration unit. This technology is designed to be retrofitted into existing fleets which means it can replace the diesel-fueled refrigeration units in the hundreds of thousands of "reefer" trailers currently on the road in the United States and Europe. Alternatively, it can greatly reduce the battery backup required for a fully electric reefer cooling system as a battery would only be needed while the vehicle is at rest.
Our technology harvests the power produced when the suspension reacts to road anomalies generating compression and rebound strokes. Our system is specifically designed to work with variable inputs created from the first inch of suspension travel on the trailer.
The system physically links to the suspension and translates its vertical travel into a horizontally mounted linear generator. A power electronics box then collects and boosts that output to the battery pack, while burning off residual energy. In heavy-truck application, the Propitious system is about six feet long and six inches in diameter. The system in total weighs about 1,800 pounds – a more compact and lightweight alternative to massive battery packs.
