i read some interesting article about nuclear rocket engines, I was wondering?

Question by Aquariumnerd Guy: i read some interesting article about nuclear rocket engines, I was wondering? they say the technology is being held back because of the high mass of the reactor, and that the power per unit mass of the reactor could be increased if we had materials that could tolerate a higher temperature, […]

What is the plasma used in ion thrusters?

Question by Apaele Jhuse: What is the plasma used in ion thrusters? Just a random question… Best answer: Answer by Big DaddyYou’re asking about the fuel? For traditional electrostatic thrusters, xenon has been the “fuel” of choice. VASIMR can reportedly make use of different elements, but will be using hydrogen when tested on the ISS. […]

MHD Propulsion (2 of 2)

These boatlets are propelled by magnetohydrodynamics (MHD). We used ten 0.34T neodymium magnets, two 9 V batteries, salt water at 10% salinity, two folded Aluminium foil electrodes and a 15 x 18 mm plastic channel. These vessels were built by two physics undergraduates for their First Year Project at Imperial College London in 2009. Video […]

Project Orion: “To Mars by A-Bomb” RARE Footage

Project Orion was the first engineering design study of a spacecraft powered by nuclear pulse propulsion, an idea proposed first by StanisÅ‚aw Ulam during 1947. The project, initiated in 1958, envisioned the explosion of atomic bombs behind the craft and was led by Ted Taylor at General Atomics and physicist Freeman Dyson, who at Taylor’s […]

Q&A: Could gravity be electrical potential energy between celestial bodies?

by ravi.k Question by Aaron T: Could gravity be electrical potential energy between celestial bodies? Such as a low low amount of Electrical potential energy that works only because of a compounding effect from the sheer mass and volume of the celestial body. I know that non-conductive materials can still build up electrical potential energy […]

Ion Lifter Schlieren Experiment.avi

This is a video using Schlieren photography to view the airflow between and around the electrodes of an Ionocraft or Lifter. The Ionocraft Lifter is a popular High Voltage hovercraft that utilizes an ion wind to create lift. Some say it even creates an Anti-Gravity field!?!? In the video you can see turbulent airflow around […]
