Proposed MDE-Based Energy Systems
HHES is developing MDE-based systems around three primary energy configurations. These are development-stage concepts and are not yet commercially available.
PROPOSED ENERGY SYSTEMS
Heat and power, or power alone.
The Maximum Delivery Engine (MDE) is the external-combustion architecture underlying HHES’s proposed energy systems.
Combined Heat and Power (CHP) configurations are designed to provide electricity and useful recovered heat. The power-focused configuration emphasizes electricity generation. Each uses an external heat source; the engine is not an internal-combustion engine.
PROPOSED CONFIGURATION
CHP — Solar + Combusted Fuel
The proposed system would accept concentrated solar thermal energy when useful sunlight is available and combusted-fuel heat at night, during clouds, or when additional heat input is required.
Potential outputs
Electricity and useful recovered heat, with third-party battery/inverter compatibility where appropriate.
Potential applications
Homes, small businesses, farms, workshops, cabins, off-grid or semi-rural properties, and other locations able to use both electricity and useful heat.
PROPOSED CONFIGURATION
CHP — Combusted Fuel
The external-combustion architecture does not fundamentally require solar heat. A fuel-fired heat source can supply the hot side directly, allowing installations where a solar concentrator is undesirable, impractical, or unnecessary to be considered.
Potential outputs
Electricity and useful recovered heat, with dispatchable operation independent of sunlight and battery/inverter compatibility where appropriate.
Potential applications
Homes, small businesses, farms, workshops, cabins, remote/off-grid properties, and locations where solar collection is impractical or unnecessary.
PROPOSED CONFIGURATION
Power — Combusted Fuel
The proposed power-focused configuration would use an external fuel-fired heat source for electricity generation. Suitable fuels may include propane and other combustible fuels, depending on the final configuration.
The external-combustion MDE architecture will offer a substantially quieter operating profile than conventional small internal-combustion generators.
Fuel-fired operation does not depend on sunlight, allowing dispatchable generation day or night.
Potential outputs
Electricity generation, with useful heat recovery not the primary objective and third-party battery/inverter integration where appropriate.
Potential applications
RVs, travel trailers, cabins, remote/off-grid sites, backup power, portable or stationary generator applications, and nighttime generation.
ENERGY UTILIZATION
Efficient, Cleaner Power
MDE systems are designed for high fuel utilization and substantially cleaner combustion than conventional small gasoline or diesel engines. CHP configurations can further improve total energy utilization by recovering useful heat that would otherwise be wasted.
EDUCATION & DEMONSTRATION
Education & Demonstration
MDE-ED — 5–10 cc Educational MDE
This active development platform is intended primarily for teachers, students, schools, universities, and hot-air engine enthusiasts.
Secondary audiences include STEM programs, engineering laboratories, technical and vocational education, maker communities, model-engine enthusiasts, and science demonstrations.
It is separate from the three proposed energy-system configurations and is not yet commercially available.
