- NASA can't explain how it works, but there's a propulsion system that seemingly violates conservation of momentum -- and it actually produces a small amount of thrust. There are a few different versions of this propellant-free thruster, called a "Cannae Drive" or EmDrive.. and there's even a Kickstarter project to try to build a similar system. Is it April Fool's day every day? [url]
- NASA is looking into every possible means to improve space travel, including the very speculative faster-than-light "warp drive" that proposes to bend space-time to get to distant destinations in a matter of weeks instead of decades. Alcubierre drives are purely theoretical, and NASA explicitly states any kind of FTL warp drive is firmly in the speculation realm. [url]
- Vortex rockets provide a practical solution for reducing the weight of a traditional liquid-fuel rocket. Conventional rockets require some (heavy) complex cooling systems to prevent parts of the rocket itself from melting and/or vaporizing away, but a vortex rocket eliminates the need for cooling by creating a mini-tornado of burning fuel where the hottest temperatures are kept away from rocket structures.
