This is more of a brief background on the history of the rocket engine.  How far after the Wright brothers did this take place?

Since the dawn of rocketry, we’ve relied on the same basic technology to get us off the ground. Fill a cylinder with volatile chemicals, then ignite them in a controlled explosion. The force of the blast is what pushes the rocket up. Nowadays, chemical rockets are the only ones with enough thrust to overcome Earth’s gravity and carry a payload into orbit. But they are not very efficient.

The heavier the payload, the more fuel a rocket needs to lift it into space. But the more fuel a rocket carries, the more fuel it needs. For long-range missions, most spacecraft rely on their initial launch speed to essentially coast to their destination. Flight planners often design routes that give the craft a gravity assist by sending it around the moon or another planet. One small cadre of scientists believes it has a quicker and more efficient way to get around in space.

The comments on this thread are all over the place and some are quite inquisitive.

We hope you like the video and look forward to more on the plasma engine concept!
