How to get thrust with electricity ?4 answersTo generate thrust with electricity, a power generation system driven by fluid pressures can be used. This system involves the use of thrust bodies, a turbocharger, a motor, a driving power source, a lever mechanism, a speed changer, a power generator, a converter, and a controller. The high-pressure fluid sprayed by the turbocharger creates high-speed flowing shielding layers on the front surfaces of the thrust bodies, reducing the pressures on these surfaces. The structural characteristics of the thrust bodies cause low flowing speed and high pressures on the rear surfaces. The difference in pressures between the front and rear surfaces generates forward thrust, which rotates the lever mechanism and drives the power generator to produce electric energy. This power generation system can be installed on the ground or water surfaces, utilizing the static pressures of the fluid to continuously generate clean new energy.
