Engines Power Our World. We Made a 10X Better One. 

From the cars we drive, to military drones, to brand-new industries like flying taxis, we rely on the combustion engine every day. But the big, heavy, and gas-guzzling engines we use hold us back. So we made an engine that could deliver up to 10X the power at the same weight.

XTS-210 vs. comparable piston diesel engine

Not Your Grandfather’s Engine

Our XTS-210 boasts up to 5X the power density and specific power of comparable piston diesel engines, delivering 25 horsepower in a two-stroke, supercharged, liquid-cooled package. This compact and lightweight engine is heavy-fuel compatible, multi-fuel capable, and optimized for hybrid-electric applications.

X-Engine vs. Wankel

Our patented X-Engine solves the problems of the legacy rotary engines without sacrificing the benefits. It's simple – it has only 2 moving parts, practically zero vibration, extremely compact and lightweight; and can run on heavy fuel, gasoline, and even gaseous fuels like propane and hydrogen.

WE'VE EARNED $30M+ IN DEPARTMENT OF DEFENSE CONTRACTS

Our engine is already proving it can outperform legacy motors. The biggest players across industries are eager to get their hands on it. And we’re only getting started.

WON $30M IN U.S. MILITARY FUNDING BY SOLVING SOME OF THEIR MOST URGENT PROBLEMS - FROM SMALLER, LIGHTER GENERATORS TO DRONES THAT CAN FLY FURTHER AND USE HEAVY FUEL.

SUCCESSFULLY SHOWN HOW OUR ENGINE CAN POWER A LAND VEHICLE USING HYDROGEN.

AWARDED ANOTHER CONTRACT OF $9M FROM THE U.S. ARMY.

Drones, UAV

Demonstration of Hybrid Electric X-Engine using jet fuel in 55lb UAV for the Army. Led to multiple contract awards.

Mobile Generators

OUR ENGINE IS POISED TO DISRUPT THE GLOBAL INTERNAL COMBUSTION MARKET

We remade the engine from the ground up, making this the first disruption to engine technology in 100 years. We have 82 patents issued and in progress, covering everything from our thermodynamic cycle to the engine design.

Growing Revenue Streams

We’re currently developing our 5th generation engine architecture. We aren’t stopping there. We’re planning for three future revenue streams while we expand our footprint across commercial and military markets.

LPI stock price over time

On March 09, 2022 we enacted a stock split, we effected a ten-for-one (10:1) forward “stock split.” As a result of this split, each share of the Company’s Common Stock was split into ten (10) shares of Common Stock. This 10:1 stock split means that effectively the share price is reduced by 10x (while the number of shares is increased by 10x). Therefore, if you paid $54 per share in the last reg A campaign, this means that post-split, you will hold 10x as many shares, but at an effective share price of $5.40 per share.

Lightweight & Compact

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

Simplicity

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.

We have 64 patents, 44 Issued and 20 Pending
