Reminds me of the Bassard Ramjet, I wonder if we could make this principle work even in deep space , where although very thinly distributed there is still gases?

Scientists arguing about stuff thats over my head...lol. you guys!

This engine is mostly electrical not combustible. Like an ion engine, it ionizes molecules then shoots out the plasma using magnets to accelerate to an oppositely charged hollow pole. There's plenty of electical potential in space (sunlight) and the cold temperature could be used for superconductive magnets. Decelerating molecules in the upper atmosphere of earth or probably any planet, moon or asteroid (basically any space gaseous material will do) to collect enough to generate propulsion seems to be the key they have unlocked. I wonder if collecting charged particles from the solar wind could do. That could accelerate a ship all the way to interstellar space.

That looks like it has significant potential. Ion drives do have implications for deep space but this method of collecting propellant is targeted at the thin atmosphere of low earth orbit not the much harder vacuum of deep space
