Military & Aerospace

Whether it’s a drone that can fly faster and farther or the ability to fit 11 generators on a pallet instead of two, our small, versatile engines are solving some of the biggest problems for the military. No wonder the Department of Defense has awarded us over $30M to date.



Demand for electric vehicles is off the charts, with an expected growth of 380% more EVs on the road by 2030. That’s creating a problem. The demand for EVs is causing a shortage in precious metals like lithium. By using our engine we can make hybrid electric cars with 80% smaller batteries.


Urban Air Mobility (UAM)

Planes are typically painted white because it weighs less than darker colors. If the color of the paint matters this much, imagine how important the weight of the engine is. By getting the same power with up to a 10X smaller engine, we’re opening up possibilities for air taxis.


Drones (UAS)

One of the key features of our Hybrid Electric X-Engine propulsion system powering drones is the ability to turn the engine on and off mid-flight, while leveraging an electric motor for quiet cruise or electric-assist sprint and climb modes. Not only does that save fuel, but lets the drone quietly move into sensitive areas with advanced capability.  The innovation made us an award winner in the US Army xTechSearch 3.0 competition.



Whether it’s bringing electric power to the front lines or to a city recovering from a natural disaster, today’s bulky generators don’t make it easy. Current 10kW diesel generators weigh nearly 1,000 pounds. But by using our engine we can make equally powerful gensets that can be carried by hand.


Hydrogen-fueled engines

Our engines have been demonstrated on a variety of fuels, including diesel, gasoline, jet fuel, and recently even hydrogen.  The exhaust from hydrogen combustion is primarily water. This unlocks a 100% green energy solution for the combustion engine market.

We Make the Cars of the Future Possible

Hybrid Electrification

Battery-powered electric vehicles have challenges on the path to a renewable future. A typical electric battery weighs over 1,000 pounds and the amount of lithium, cobalt, and nickel currently needed to make them is unsustainable. Our small, efficient engines in a hybrid-electric car can make it possible for the battery to be up to 10X smaller.

36lbs of fuel can displace 1,000 pounds of battery
LPI Hybrid Power System eliminates up to 80% of the battery pack
LPI engines allow more range for an electric vehicle by combining a smaller, lighter, more cost effective battery, with the ease of rapid refueling for longer journeys when required
LPI's technology could be critical in addressing a possible lithium shortage


Hydrogen is the sixth fuel variation that has been proven to power the X-Engine along with gasoline, propane, kerosene, diesel, and jet A fuel
The primary emission of an Engine running on hydrogen fuel is water, making it a potentially zero carbon-emission, green engine

Lightweight & Compact

Up to 80% smaller and lighter than the traditional piston Diesel engines.


Only two primary moving parts, optimally balanced.

High-Efficiency and Lower Fuel Consumption

The optimized thermodynamic cycle has the potential to decrease fuel consumption by 30%, thereby lowering CO2 emissions and the cost of running an engine

Quiet and Near-Zero Vibration

With lower pressure exhaust and just two moving components that are optimally balanced, the engine is inherently quiet, and offers exceptionally low vibration.
