While spark-ignition and compression-based engines rely on fuel, generate waste, and pollute, and electric motors — though powerful and compact — still demand constant input and suffer from inefficiencies, the EFE is designed to overcome both. Unlike traditional renewables like solar, wind, biomass, or geothermal — which are location-dependent, bulky, and expensive to build — the Electron Fluid Engine delivers clean, high-efficiency power in a compact, scalable, and affordable format. Our modern energy systems are inefficient, wasteful, and heavily dependent on fuels or grid infrastructure. Affordable, portable, and sustainable energy options remain limited — and classrooms rarely have access to hands-on tools that demonstrate real innovation.
