Fuel Efficient Five-Gear Rocket Engine Design - Rocket engines used today to launch satellites run at maximum exhaust velocity until they reach orbit. For a car, this would be analogous to staying all the time in first gear. Georgia Tech researchers have designed a new space rocket which works as if it has a five-gear transmission system.

  • Featured: Propulsion / Anti-Gravity > Lifters >
    Development of Ionic Electrical Thrust Technology - In the last few years, electric thrusters, commonly referred to as 'Lifters,' have achieved popularity as a home science project on the Internet. Advocates claim they are a significant technological breakthrough that promises anti-gravity anomalies and a possible new era of solid state electric flight. (PESWiki; Oct. 18, 2008)

    EmDrive - Chinese Say They're Building 'Impossible' Space Drive - Chinese researchers are proceeding to build a demonstration version of a technology developed by Satellite Propulsion Research Ltd (SPR Ltd) of the UK, who have tested both an experimental propellant-less thruster and a demonstrator engine that use patented microwave technology to convert electrical energy directly into thrust. (PESWiki; Sept. 27, 2008)
  • Applied Plasma Technologies Applied Plasma Technologies (APT) develops and manufactures plasma assisted combustion systems for reliable ignition, flame control, clean and stable combustion of different fuels in gas turbines, high speed propulsion systems, boilers, technological burners.
  • Magnetohydrodynamics:Plasma-Powered Flying Saucers - With a span of less than 15 centimetres, Subrata Roy's aircraft qualifies as a micro air vehicle (MAV), but it has an unconventional design to say the least. It is a saucer shape covered with electrodes that ionise air to create a plasma. (PESWiki; May 10, 2008)

The Cutting Edge

On Feb. 24, 2008, Daniel Bowers wrote:

I was just looking at the new propulsion wiki page and realized that those systems are primitive compared to the other concepts for space propulsion.

Plasma rocket:

The late Robert Bussards concept for a plasma fusion rocket

Antimatter Propulsion

Antimatter

Traveling at 186,000 miles per second we could get to Alpha Centauri in 4 years. Current methods of space travel can do this in 40,000 years. 7 or even 10 miles per second doesn't get us anywhere.

The future of space exploration lays in antimatter rockets

Antimatter sail

NAIC Mars explorer antimatter concept

There are many variations of these types of systems, the first generation will most likely be antimatter assisted plasma fusion rockets. Well, first fusion, then fusion rockets, then antimatter assisted plasma rockets and ultimately antimatter propulsion systems which will lead the way to Alpha Centauri and beyond within the next couple of centuries.

Other Technologies

  • Successful test of superconducting plasma rocket engine - Ad Astra Rocket Company has successfully demonstrated operation of its VX-200 plasma engine first stage at full power and under superconducting conditions. VASIMRA engines could enable space operations far more efficiently than today's chemical rockets, and ultimately they could also greatly speed up robotic and human transit times for missions to Mars and beyond. (Space Fellowship; July 6, 2009)
  • Laser-Powered Aircraft Are The Future of Flight. Maybe - Leik Myrabo first got the idea in 1988 and called it LightCraft, a funnel-shaped craft with a parabolic reflector back in 2000. It channels the heat generated by a laser into its center, causing it to explode, thus generating thrust. Small jets of pressurized nitrogen spin the LightCraft at 6,000 RPM to maintain stability. (Wired; Feb. 20, 2009)
  • A Workable Fusion Starship? - Friedwardt Winterberg's innovative propulsion concept now weds magnetic mirror technologies with fusion. The interplanetary vehicle has an exhaust velocity of 100 km/s, while the launcher vehicle gets 10 km/s. (Centauri Dream; Jan. 23, 2009)
  • Unitel Aerospace and macroscopic quantum tunneling - Tim Ventura interviews Larry Maurer, CEO of Unitel Aerospace, which has been a leader in community space-activism with their breakthrough propulsion approach to future space flight. (American AntiGravity; June 27, 2006)
  • NASA Holds Competition to Develop Space Vehicles - US space agency is holding a competition to develop space vehicles NASA doesn't have the time or resources to develop. The winning companies will get $500 million and NASA will merely lease them as the need arises. (Slashdot; June 25, 2006)
  • Fuel Efficient Five-Gear Rocket Engine Designed - Rocket engines used today to launch satellites run at maximum exhaust velocity until they reach orbit.

(Slashdot; Feb. 24, 2007)
  • Human Power > Moving Big Rocks - Wally Wallington has demonstrated that he can lift a Stonehenge-sized pillar weighing 22,000 lbs and moved a barn over 300 ft. What makes this so special is that he does it using only himself, gravity, and his incredible ingenuity. (J Walk Blog; Oct. 17, 2006)
