The LiquidPiston 'X' engine is an advanced rotary internal combustion engine that is fuel efficient, extremely compact and lightweight, durable, quiet, and has near-zero vibration. The X-Mini engine is a 70cc gasoline SI engine, the size of a grapefruit, rated at 3-5 HP, weighing only 4 lbs. This engine is the company's most mature technology demonstrator - achieving 50% better fuel economy than comparable displacement piston engines. This engine can be used in generators, chainsaws, mopeds, UAVs, etc. In 2015 the company completed a $1M DARPA Feasibility study, and the company expects up to $12.5M in DoD contracts to develop diesel versions of its X engine for generator and UAV applications in 2016. The "X4" concept is a 30kW Diesel engine achieving 50% better fuel economy than a piston engine, in a 10x8x8" package, weighing 25lbs. While developed initially for the DoD, this engine will have applications including as a range-extending power source to increase range of an EV.

Drooid develops micro-scale autonomous swarms for reconnaissance, breaching, and high-risk mission automation. Our aerial ornithopters and ground crawlers are palm-sized, low-cost, and expendable, allowing operators to deploy dozens to hundreds of units simultaneously without the risk or noise of traditional drones. Using onboard AI, mesh networking, and a unified command interface, Drooid swarms can map environments, locate threats, clear rooms, or secure perimeters with minimal operator input. Drooid brings next-generation autonomy to the tactical edge — delivering capabilities previously reserved for much larger, more expensive unmanned systems.

ZPods eliminates the need for pumps, tanks, tubes, nozzles, manifolds, and more. Traditional lubrication systems can’t compete with our cost, weight and performance benefits. Traditionally, lubrication is delivered to the core of a jet engine from the outside in, traveling long distances. Once it enters the engine, its journey isn’t done. It travels through many passages to reach its destination. This system is best for engines that need to last thousands of hours. The expendable engine only needs to last minutes to hours. ZPods allows for oil to begin directly where it is meant to be for lubrication. ZPods delivers just enough oil to the desired hardware without the need for any of the traditional hardware that negatively impacts performance. Just enough, without all the other stuff. At the specified temperature, the pod’s shell breaks down, oil is released and the engine’s natural physics take over to transport the oil to the parts that need it for operation.
