ROADMAP & VISION
Current Status
AEPEP is at an advanced proof-of-concept stage. The core condensation device (VECC) has been designed, internal geometries finalised, and physical hardware is under manufacture using an investment casting process. A comprehensive experimental protocol has been developed covering thermodynamic validation, condensation rate measurement, power generation confirmation, and closed-loop cycle demonstration.
The proof-of-concept system is designed to produce 250–350 watts of continuous electrical output at an overall thermal efficiency of approximately 21%. Once the physics is validated, scaling is an engineering challenge governed by well-understood principles of heat transfer and turbine design.
