American engineers have achieved a historic feat: a jet engine powered solely by plasma (electricity that ionizes the air) ran continuously for 70 hours without a single drop of fossil fuel. Zero emissions, zero carbon, thrust generated only with air and electrical energy.

The test proves that the technology already supports long-term operations, paving the way for perpetual drones and, in the future, commercial aircraft that fly cheaper and without polluting. Aviation has just taken the biggest leap towards an electric future!
