Developing the Next Stage of Heat-Driven Power

Maximum Delivery Engines is evaluating multiple MDE configurations and scales to determine the most practical path to physical prototype validation.

MDE designs undergo analytical and computational evaluation before physical prototype fabrication, followed by instrumented hardware testing.

Prototype configuration and sequencing will be selected based on engineering results, fabrication practicality, and development priorities.

Recent thermodynamic calculations indicate greater ideal power potential for pressurized MDE configurations than previously anticipated. This has expanded the applications under investigation to passenger-car hybrid generation and larger generators.

The passenger-car concept is a series hybrid: the MDE would drive a generator, with electric motors driving the wheels and a small traction battery supporting immediate driving, acceleration, and passing. This vehicle concept is an opportunity for further study as engine development progresses.

Double-acting pistons use both working faces. Heat-transfer improvements are being investigated while controlling inactive gas volume. These concepts do not yet establish net output or commercial feasibility.

Prototype testing is intended to replace design assumptions with measured data and establish the basis for assessing practical performance.

• Actual mechanical and electrical output, thermal efficiency, and heat-transfer performance.
• Pressure and mechanical losses, cooling requirements, and the operating envelope.
• Noise and vibration, seal and bearing behavior, and durability.
• Manufacturing cost and assembly complexity, supported by manufacturing analysis.

Proposed systems include Combined Heat and Power (CHP) using solar plus combusted-fuel heat, CHP using combusted-fuel heat alone, and power-focused combusted-fuel generation. All three would use the same fundamental external-combustion architecture.

Compatibility with third-party batteries and inverters could support variable demand. Integration and heat recovery also require validation.

Potential advantages in noise, fuel utilization, and emissions require measured comparisons with existing systems.

Maximum Delivery Engines welcomes interest from strategic investors, manufacturing partners, engineering collaborators, and prototype-development partners.
